Frequently Asked Questions

ny birthmark that grows, darkens, develops irregular borders, or becomes itchy or painful warrants prompt evaluation. These changes can be early signs of melanoma or other skin cancers, so early dermatologic assessment is crucial.
Topical antifungal creams containing clotrimazole, terbinafine, or miconazole can be effective if applied twice daily for 2–4 weeks. Keep the feet dry, change socks regularly, and use a separate towel for each foot to reduce moisture and prevent reinfection. If symptoms persist, consult a clinician for stronger prescription therapy.===
fungal nail infection often starts with a small white or yellow spot near the cuticle or on the nail surface. Over weeks it may thicken, discolor to a yellow‑brown hue, and become brittle or crumbly. If you notice these changes, especially on the toenails, it’s a good idea to see a clinician early to prevent spread and more extensive damage.
Eczema typically presents as itchy, red patches that may ooze or crust, often in flexural areas (inside elbows, behind knees). Psoriasis usually shows well‑defined, silvery scales on raised plaques, commonly on elbows, knees, scalp, or the back of the hands. A dermatologist can confirm with a skin biopsy if the presentation is unclear.
