Ten reasons why your nails might change colour

My toenail is changing colour. What can be causing it?

The function of a toenail is protection of the tip of the toe. If we are lucky, we will progress through life with few changes to their appearance, but that isn’t always the case.

We all have a good idea of what we consider a ‘normal’ nail, but sometimes all or part of the nail can start to change colour. In this blog we look at how and why this can happen.

brown-black discolouration (occasionally red)

Although uncommon, the first condition to eliminate is (subungual – under the nail) melanoma. Speak to your podiatrist or GP if you are concerned. In reality, there are numerous benign causes.

Longitudinal melanonychia

This is a term used to describe a  strong and noticeable pigmented band – normally brown – that runs down the nail from the bed to the tip. This condition normally affects more than one nail at a time.

This is quite common in Black-skinned, Asian, Hispanic, and Middle Eastern individuals who frequently have benign/harmless longitudinal pigmented bands. This is due to the naturally occurring pigment cells or melanocytes that make their skin darker.

The number and width of the bands tend to increase with age.

However, the presence of a new, single – only occurring on one of ten nails –  dark coloured band in an adult could represent a melanoma and should be checked immediately.

There are additional uncommon causes including systemic disease and medication to numerous to list here.

Subungual haematoma (bruise)

Following trauma – kicking something, dropping something on the toe – blood can accumulate in the space between the nail bed and nail plate. It can  also happen following vigorous exercise/dancing when you don’t remember ‘bashing it’.

The discolouration is often accompanied by considerable pain due to the pressure created under the nail. If you visit a Podiatrist as soon as possible after the injury occurs, it is possible to painlessly drain the fluid and bring immediate relief.

Yellow/white discolouration (occasionally orange)

Onychomycosis (fungal nail)

Nail fungus usually cause a yellow-white discolouration, but occasionally it can be black or orange.

Nail fungus usually starts at the tip or sides of the nail and work their way upwards towards the nail bed frequently following trauma.It is very common for patients to report that fthe fungus appeared after damaging the nail.

If caught early, infected nail can sometimes be trimmed away to prevent spread.

If allowed to become established, treatment can be difficult and lengthy. For further information https://maidenheadpodiatry.co.uk/what-can-i-do-about-my-fungal-nail/

Some medications can also produce similar discolouration.

Cream, Dark yellow or white-yellow nails

Trauma

When nails have experienced trauma, the protective mechanism can be triggered, and they increase in thickness. That increase in thickness causes the colour of the nail to darken and take on a changed appearance. The nail will also grow more slowly.

Psoriasis

This condition can occur just on nails with no history or occurrence on the skin. The changes can be similar to, and are often mistaken for, a fungal nail infection and it is important to establish which you have, to allow appropriate treatment

Paronychia

Or infection of the nail bed. This can lead to a change in appearance as pus builds up under the nail. This condition can require release of the pus and prescription of anti-biotics, depending on severity.

Some medications can also produce similar discolouration.

Yellow Nail syndrome

This is a very rare condition characterised by very curved, transversely thickened, smooth, yellowed nails and is associated with lymphoedema, pleural effusion, and (usually) ascites.

White nail discolouration

Minor trauma

A common cause, and tends to produce small localized areas of whiteness, like white spots on the nail.

There are a number of other systemic conditions that can also lead to white nails but they are too uncommon and numerous to be listed here.

Green/blue nails

Pseudomonal nail infection

Pseudomonas infection is often found on the underside of a nail (it can also be found on the skin) which has already lifted, often due to trauma or previous infection. It is characterised by green-blue, or occasionally black, discolouration. This infection is relatively harmless in healthy adults. If you are immune compromised you should seek advice.

Some medications can also produce similar discolouration.

Oral medication (terbinafine) has been recommended for my fungal nails – is it safe?

Terbinafine and fungal nails

There are too many topical anti-fungal preparations currently on the market to list them all here. Their success also varies enormously and is covered in another blog. click here to read.

Having visited your Podiatrist or GP and had your nail infection confirmed as fungal, there are three main options.

  • Do nothing
  • Try an over-the-counter or prescription anti-fungal topical application
  • GP prescribed oral medication

There are two mainly used oral anti-fungal medicines – itraconazole and terbinafine. This blog will look specifically at terbinafine (hydrocloride) because at Maidenhead Podiatry we are frequently asked about its potential side effects.

Liver problems were only reported in 0.1% of patients. 1 in 1000; but only 1 in 50,000 to 1 in 120,000 were serious

What is terbinafine (hydrochloride)?

Terbinafine is an allylamine drug, meaning it works by inhibiting squalene epoxidase, an enzyme involved in the synthesis of ergosterol, a component in fungal cell walls.

Terbinafine is available as cream, gel, spray and, of course, tablets for oral administration at the time of writing.

What is the history of terbinafine?

It is used in the treatment of onychomycosis or fungal nails (as well as a range of fungal skin infections). Terbinafine has been available since the early 1990s in the UK and the late 1990s in USA, but there has always been some reluctance regarding its potential side effects particularly those affecting the liver when taken orally.

When terbinafine was first deployed as a new antifungal, the choices for treatment of fungal nails were limited. Topical treatments were often, and remain, disappointing.

Until the 90s, oral griseofulvin and ketoconazole were the oral drugs of choice, indicated for dermatophyte or fungal nail infection, but they were far from effective. Generally, they required long courses with a narrow spectrum of activity leading to many patients giving up when they experienced unpleasant side effects.

The idea of a new, modern, antifungal drug was appealing with subsequent studies suggesting it had twice the success rate of griseofulvin and it became widely used in the treatment of dermatophyte nail infections.

How is terbinafine metabolised?

As with many drugs, terbinafine is metabolised by the liver and excreted by the kidneys, consequently a reduction in function of either of those two organ systems could result in serious problems and correct prescribing is crucial.

Terbinafine is highly lipophilic (combining with or dissolving lipids) and tends to accumulate in hair, skin, nails, and fatty tissue where it inhibits fungal growth..

What about terbinafine and liver damage?

The possibility of liver disease (hepatotoxicity) with terbinafine has long been known and drug manufacturers have highlighting that it should not be prescribed for patients with liver disease. Terbinafine, like nearly all classes of medications, has been shown to be able to induce idiosyncratic liver injury or drug induced liver injury (DILI), but that doesn’t mean it will.

The causes of DILI are many, although pre-existing liver disease may play a part. In otherwise healthy individuals it’s cause and reason for development is unclear, although genetic susceptibility may be responsible. As a consequence, The British National Formulary advises it should not be used in patients with known liver disorders. For those that are prescribed the drug, they should have liver function tests before starting and periodically after 4–6 weeks of treatment to assess liver function.

The test monitors the levels of liver enzymes present in the bloodstream. Elevation of these enzyme levels can signal early changes in liver function. Tablets are often prescribed a month at a time, the next month being prescribed only following a successful test.

Is terbinafine safe?

Hepatotoxicity or liver function problems are rare but the more common side effects in patients taking the drug include

  • gastro-intestinal upset,
  • taste disturbances,
  • headache
  • rashes

Further, liver problems may not be as common as is perceived. A 1996 British study reviewed 9879 patients who had taken the oral terbinafine. Half of these had other illnesses and conditions and were taking other medications at the same time. 14% reported various side effects but only half of these were thought to be related to the terbinafine as reported by their physicians.

Liver problems were only reported in 0.1% of patients. 1 in 1000

(14 cases) of which 10 cases were classified as minor and transient elevations in liver enzymes. In addition, some of these patients were found to have pre-existing history of liver disease (gall bladder disease, alcohol related changes, hepatitis and cirrhosis).

There were no terbinafine associated deaths.

The National Library of Medicine Liver Toxicity Database report on terbinafine shows less than one percent of patients see an increase in liver enzymes in the bloodstream and most resolve with stopping treatment. It estimates the probability of developing elevated liver enzymes levels requiring stopping treatment is about 0.31% for 2 to 6 weeks’ treatment and 0.44% for treatment lasting longer than 8 weeks.

It concludes that clinically apparent liver injury from terbinafine occurs rarely, in around 1 in 50,000 to 120,000 prescriptions.

How do I decide?

Remember,

  • no drug can ever be 100% effective for everyone so success isn’t guaranteed
  • successful resolution doesn’t mean you can’t get it again
  • re-infection within 12 months is not only possible but likely
  • successful resolution must be followed by an anti-fungal regime
  • leaving a fungal nail untreated rarely causes problems

As with most classes of drugs, terbinafine can potentially lead to liver problems. However, the data from the above control suggests that oral terbinafine is safer than perhaps it is perceived, and minor side effects are far more likely for most patients than serious liver damage.

Data from studies suggest the risk of serious liver injury to be between 1 in 50 000 and 1 in 120 000

Despite its rarity, patients taking terbinafine who exhibit any of the symptoms of liver problems (nausea, vomiting, abdominal pain, fatigue, anorexia, general itching and dark urine) should urgently be referred for further assessment.

Podiatry

Podiatry is defined as the diagnosis and treatment of foot disorders; however, we assess, diagnose and treat from the knee down. We also treat warts on hands.

Chiropractic

Chiropractic is the management consists of a wide range of manipulative techniques designed to improve the function of joints, relieve pain and ease muscle spasm.

Chiropractors don’t only treat backs and can help with any soft-tissue or structural issues.

What is Podiatry?

Podiatry like many health care professions has general practitioners and specialists.

A general practitioner will treat anything from corns to verrucas and from plantar fasciitis or heel pain to ingrown toenails. We are all licenced to use local anaesthetic, perform minor surgeries such as ingrown nail removal and dispense antibiotics, if and where appropriate.

We provide vascular assessment and diabetic screening as a matter of course when requested or required. We have Podiatrists with special interests in areas such as diabetic care and biomechanical assessment and gait analysisGait analysis includes being filmed on a treadmill followed where appropriate by prescription of custom moulded orthotics together with an integrated exercise and rehabilitation program.

Seven Podiatrists and two Chiropractors trained in using the latest treatment and cutting-edge technology for a range of common conditions.

Cutting edge technology

Shockwave, which is a percussive mechanical treatment for chronic, or long-term, soft tissue pain such as heel pain, Achilles pain, hip pain and of course plantar fasciitis although it can be used anywhere in the body. It is used by both Podiatrists and Chiropractors

We were one of the first clinics in the country to use Swift, a microwave generator for the treatment of verrucas. We also offer salicylic acid, freezing and needling.

We offer all general foot care too including fungal nails, athlete’s foot, splits, fissures and infections. We also provide foot care in nursing and care homes as well as a domiciliary/home visiting service.

What is a Podiatrist?

What is a Podiatrist and what can they do for me?

This article will guide you through the many and varied aspects of Podiatry and help you find the foot care that suits you best. To assist in stopping the development of preventable foot problems and advise you in self care.

To offer a better understanding of the foot care options available to an individual we have split this blog into sections starting with the simplest or self care and escalating to the most complex or podiatric surgery as an end point.

  • Self care and footwear

 

Not everyone needs to become a patient. Many foot conditions can be safely and appropriately managed with the right equipment, skills and confidence.

Many foot health advice leaflets are available through the NHS and the Society of Chiropodists and Podiatrists and your Podiatrist will be happy to give you advice and guidance.

Poor choices in footwear can cause significant foot problems and seeking and following advice to make good choices of appropriate footwear can prevent development of new conditions, aggravation of existing ones and prevention of falls. Again, your Podiatrist will be happy to give you advice and guidance.

  • Footcare

Simple footcare is defined as nail cutting and skin care including the tasks that healthy adults would normally carry out as part of their daily personal hygiene routine.

Of course this doesn’t apply to everyone but it is an important aspect of footcare that ensures many individuals check their feet regularly while still mobile and pain free.

For those who do attend clinic regularly for simple footcare, examination of the feet during a routine appointment acts as an early detection system ensuring prompt intervention and prevention of developing more serious foot health problems.

PODIATRY

  • Core Podiatry
  • Nail surgery
  • Warts and verrucas
  • Fungal nails
  • Long term and neurological conditions

 

Core Podiatry is defined as ‘the assessment, diagnosis and treatment of common and more complex lower limb pathologies associated with toe nails, soft tissues and the musculo-skeletal system with the purpose of sustaining and improving foot health. (Farndon 2006).

The main foot conditions affecting older people (as opposed to children) requiring core podiatry are -nail problems, corns, callus, toe deformities, and falls prevention.

These conditions can be managed successfully by Podiatrists in the NHS and Private practice using a range of treatments including sharp debridement (scalpel), pharmacology (creams, tablets, steroid injection) and therapies (often in conjunction with footwear advice and and prescription of orthoses where appropriate0.

Although the call for Nail surgery is small – approximately 8 per 1000 GP patients – there is certainly a need for an effective, non-recurring treatment.

Since the 1970s partial or total nail avulsion has become a standard Podiatry procedure where part (the sides) or all of the nail are removed painlessly to the nail bed under local anaesthetic to resolve recurring problems with ingrown nails.

The likelihood of regrowth is reduced to almost zero (0.5%) with the application of  phenol to the nail bed.

Warts and verrucas are small skin growths caused by the human papilloma virus. Verrucas are warts on the feet, common in children and although harmless they can be painful.

Most verrucas will clear up without treatment within two years but there are numerous treatments available through your Podiatrist including

Fungal nails are very difficult to treat successfully. There are numerous topical applications available as well as GP only prescribed oral medication. Your Podiatrist will discuss your best options and agree a treatment plan.

Long term and neurological conditions include conditions such as Diabetes, rheumatoid arthritis, stroke and Parkinson’s and a Podiatrist’s management often involves management and prevention of potential escalation of foot problems.

Core podiatry is essential in maintaining the integrity of the feet of people whose medical condition places them at risk of developing complex problems.

Falls prevention. Foot problems in older people are often associated with impaired balance and mobility and where there is a history of multiple falls there are usually more foot issues.

The existence of a corn, bunion or poor footwear choices are often at play and podiatry intervention can moderate the risks.

ORTHOTICS

  • Orthotics, footwear and Musculo-skeletal provision
  • Podopaediatrics
  • Sports injuries
  • Footwear

Orthotics, footwear and Musculo-skeletal provision. Bio-mechanics and bio-mechanical assessment are an essential part of podiatry provision and the discussion of findings and correction of underlying issues with orthoses can have positive implications across the breath of podiatry services.

Many patients present with musculo-skeletal pain caused by bio-mechanical problems which can involve foot, knee, hip and lower back affecting gait (the way they walk).

Often the most cost effective and appropriate treatment is the provision of orthoses (specialist insoles) which modify and correct the bio-mechanical problem.

There are a number of different orthoses that can be prescribed by your Podiatrist depending on presenting condition and patient need. Orthoses range from a simple heel raise or cushioned insole to specific complex custom devices.

Podopaediatrics focuses on provision of Podiatry for children. This ranges from treatment of warts and verrucas to early identification of foot deformities. From gait assessment to prescription of orthoses.

Sports injuries often occur due to abnormal rotation and deformation of joints and/or muscles. Podiatrists target improvement and resolution through bio-mechanical assessment and prescription of orthoses combined with strengthening exercises and footwear.

Footwear choices can directly affect foot conditions. Podiatrists offer advice from correct choices when buying shoes to measuring for custom made footwear depending on requirement.

SPECIALIST PODIATRY

– relates mainly to long term conditions and may or may not be provided within a general podiatry clinic.

  • Diabetes
  • Systemic musculo-skeletal disorders
  • Dermatology
  • Advanced technology

Diabetes care is one of the basic provisions of any Podiatry practice and your podiatrist can offer regular foot health assessment as part of good diabetic control and patient education.

Early detection of foot problems can ensure correct management and reduce the likelihood of critical long term changes.

Systemic musculo-skeletal disorders such as rheumatoid arthritis (RA) increase the need for a range of basic foot care services. Up to 90% of people with RA have some kind of foot involvement sometimes leading to the formation of callus corns and occasionally ulceration.

Early Podiatric intervention can improve long term outcomes.

Dermatology can be considered part of core Podiatry as many of the common skin problems seen on the feet are amenable to Podiatric treatment. From tinea pedis (athlete’s foot) to melanoma.

From verrucas to cellulitis you can ask your Podiatrist for advice.

Advanced technology is becoming more a part of day to day Podiatry provision. At Maidenhead Podiatry we use Swift – a microwave treatment – for verrucas, Shockwave for chronic soft tissue pain and Cryopen for freezing warts and verrucas.

EXTENDED SCOPE PRACTICE

Podiatrists who work in extended scope practice usually work in the NHS although they can be available in larger private practices and have undertaken additional training in their clinical areas  and may actively engage in the following –

  • non-medical prescribing
  • requesting blood tests
  • requesting scans
  • interpretations of test results
  • injection therapy
  • advanced vascular investigations

PODIATRIC SURGERY

Podiatric surgery is surgical treatment of the foot and associated structures carried out by a Podiatric Surgeon often as a day case and under a local anaesthetic.

In Conclusion good foot health has a fundamental link to health and well being. Poor foot health can have a significant impact on mobility, independence, and quality of life.
