Fungal nail infection
Onychomycosis may cause thickening, yellow or white discolouration, crumbling, separation from the nail bed or debris under the nail.

Nail health assessment · OMR
Nail disorder treatment
in Chennai.
Discolouration, thickening, splitting, pain or nail-shape changes can have very different causes. Diagnosis comes first.
At Ram Skin Clinic in Thoraipakkam, OMR, nail problems are assessed in the context of the surrounding skin, toes or fingers, medical history, medicines, footwear, occupation and possible infection before treatment is planned.
Why diagnosis matters
Nail changes are not always fungal.
Thickened or discoloured nails are commonly blamed on fungus, but trauma, psoriasis, eczema, lichen planus and other nail disorders can look similar. Treating the wrong cause can delay improvement.
The American Academy of Dermatology notes that a dermatologist may examine the nail closely and, when needed, take nail clippings or debris for testing before prescribing antifungal treatment.
Common nail problems
What can cause abnormal nails?
The appearance of the nail plate, nail bed and surrounding skin can provide useful clues.
Psoriasis & inflammatory disease
Nail psoriasis can cause pitting, thickening, lifting or colour changes. Eczema and lichen planus can also affect nail texture and growth.
Trauma, pressure & ingrown nails
Repeated pressure from footwear, sport, manicures or injury can damage nails. Ingrown toenails can cause tenderness, swelling and secondary infection.
Brittle or splitting nails
Frequent wet work, chemicals, ageing, repeated trauma and some medical or nutritional problems can contribute to brittle nails.
Pigment or colour changes
Dark streaks, persistent red or brown areas, or unexplained colour change should be assessed, particularly if new, widening or affecting a single nail.
Assessment
How are nail disorders diagnosed?
A dermatologist may examine all fingernails and toenails, not just the affected one, and look for changes in the surrounding skin or elsewhere on the body.
Depending on the suspected cause, testing may include nail clippings, scraping, microscopy or culture. If an inflammatory disorder or unusual pigment change is suspected, further testing or biopsy may occasionally be considered.
When related skin disease matters
Nail changes can be part of a broader dermatologic condition. See our pages on psoriasis treatment, lichen planus treatment and skin infections.
Important: Do not start prolonged antifungal tablets solely because a nail looks thick or yellow. Confirming the likely cause helps avoid unnecessary treatment.
Treatment planning
How are nail disorders treated?
Treatment depends on the diagnosis, number of nails affected, severity, symptoms and medical history. Nail growth is slow, so improvement often takes time even when treatment is working.
Fungal nail disease
Selected cases may be treated with topical or oral antifungal medicine. The choice depends on extent, nail site, test results, other medicines and health factors.
Inflammatory nail disease
Psoriasis, eczema or lichen planus may need anti-inflammatory treatment directed at the underlying condition rather than antifungal therapy.
Trauma & ingrown nails
Reducing pressure, changing footwear, careful nail trimming and treating inflammation may help. Painful or recurrent ingrown nails may need procedural assessment.
For fungal nails, AAD guidance emphasises confirming the diagnosis because several other nail conditions can mimic fungus. Treatment selection depends on the individual nail pattern and patient factors.
Nail care
Everyday habits that can protect nails.
- Keep nails clean and dry, especially between the toes.
- Trim nails straight across and avoid cutting deeply into the corners.
- Wear well-fitting footwear with enough toe room.
- Avoid repeatedly picking, scraping or drilling thickened nails yourself.
- Use gloves for prolonged wet work or chemical exposure.
- Do not share nail clippers, footwear or manicure tools.
When to arrange an earlier review
Seek assessment sooner for significant pain, swelling, pus, rapidly worsening redness, a new or changing dark streak, persistent bleeding, nail loss after trauma, or nail problems in a person with diabetes, poor circulation or reduced immunity.
If there is surrounding redness, drainage or suspected infection, our skin infection treatment page may also be useful.
Follow-up
Why follow-up can matter.
Toenails and fingernails grow slowly. A damaged nail may take months to fully grow out, so treatment is often judged by whether healthy new nail is emerging from the base rather than whether the entire nail looks normal immediately.
Consultation & cost
Cost depends on the diagnosis.
Consultation cost and any additional testing or procedures depend on what is clinically required. A treatment plan is discussed after examination rather than assuming every nail problem needs the same medication.

Frequently asked questions
Nail disorder FAQs
Are all yellow or thick nails caused by fungus?
No. Fungal infection is one cause, but trauma, psoriasis, eczema, lichen planus and other nail disorders can produce similar changes. Examination and sometimes testing help distinguish them.
How long does fungal nail treatment take?
Nails grow slowly, so visible improvement can take several months. Even after the cause is controlled, the damaged nail must grow out before the appearance fully changes.
Can nail psoriasis look like fungus?
Yes. Nail psoriasis can cause thickening, lifting, pitting and discolouration. Some patients may also have both psoriasis and fungal infection, which is one reason diagnosis matters.
When should a dark nail streak be checked?
A new, widening, irregular or unexplained dark streak—especially in a single nail—deserves dermatologic assessment. Trauma and benign pigmentation are common causes, but examination is important.
Should I use antifungal tablets without testing?
Not routinely. Because several nail disorders mimic fungal infection, a dermatologist may recommend confirming the likely diagnosis before oral treatment, particularly when prolonged therapy is being considered.
Prepare for your visit
What to bring to a nail consultation.
If possible, avoid removing all visible nail changes immediately before the appointment. Bring a list of medicines and supplements, details of prior antifungal or steroid treatments, and photographs showing how the nail changed over time.
Tell the dermatologist about diabetes, circulation problems, immune suppression, psoriasis, eczema, recent injury, sports activity, salon procedures or repeated wet work.
