Nail Problems a Dermatologist Treats: Fungus, Ingrown & Discolouration
Quick Answer: Nails are dermatology territory: fungal nails (thickened, yellowed, crumbly — confirmed before treated, because half of "fungal" nails aren't, then cured with months-long topical or oral antifungal courses matched to severity); ingrown toenails (conservative care early, minor matrix procedures for the recurrent — the permanent-corner fix); and the discolouration-and-change file — where one signature rule lives: a new dark streak in a single nail gets urgent dermatoscopic evaluation. Nails grow slowly; every nail treatment is a patience contract measured in months.
Fungal Nails, Done Properly
The confirm-first doctrine: psoriasis nails, trauma nails, and ageing nails impersonate fungus constantly — KOH/culture or clinical-dermatoscopic confirmation before months of treatment protects the calendar and the liver. Then severity-matched treatment: medicated lacquers for early-limited disease (long faithful application runs), oral terbinafine-tier courses for established involvement (weeks-months protocols with the screening-and-interaction review — supervised, per this hub's standing rule), and the recurrence-prevention layer (footwear rotation-and-hygiene, treating the athlete's-foot reservoir, trimming discipline). The visual contract: cured nails grow out clear from the base over 6–12 months — the old damaged plate doesn't transform, it gets replaced.
Ingrown Toenails and the Permanent Fix
Early-stage care: warm soaks, cotton-wisp lifting, straight-across trimming re-education, and the footwear-width conversation (the corns article's toe-box culprit reoffending here). The recurrent-corner cases: partial nail avulsion with matrix treatment (phenolisation) — a minor clinic procedure retiring the offending nail edge permanently; diabetic feet route through the vigilance rules as everywhere.
The Changes That Earn Examination
The bold rule first: a new longitudinal dark band in one nail — especially widening, irregular, or extending to the skin fold — is an urgent dermatoscopy case (nail-unit melanoma's presentation, and acral vigilance matters in Indian skin). The broader file: pitting-and-lifting (the psoriasis-lichen nail clues), clubbing and spoon-nails (systemic signposts routed onward), white bands-and-patches, and the post-illness ridging (Beau's lines) that tells recent-history stories — nails are the skin's dashboard, and reading them is the visit.
FAQs
My nail's been yellow-thick for years — bother treating? Confirmed fungus is curable at any age of infection — the six-month grow-out is the only price.
Are salon pedicures safe with a fungal nail? Instrument-hygiene risk runs both directions — treat first, and choose sterilisation-conscious salons after.
Home remedies (vinegar soaks) for nail fungus? Adjunct-tier at generous best — established plate disease answers to real antifungals.
Both my big toenails grow inward every month — destined for surgery? The matrix-edge procedure is a one-time fix most serial sufferers wish they'd taken years earlier — the consult sorts candidacy.
