Ringworm before and after treatment

Ringworm is a fungal infection of the outer skin, not a worm. It can begin as a small irritated area and develop a clearer centre with a more active, raised or scaly border. A [Skin Rash](/symptoms/skin-rash/) or [Scaly Skin](/symptoms/skin-scaling/) can have other causes, so appearance alone cannot confirm the diagnosis.

With treatment, itching and new outward growth often improve before the skin looks completely normal. Residual redness, darker or lighter colour, and mild dryness may linger while the surface repairs. Compare progress by checking whether the patch is enlarging and whether new areas appear, rather than judging colour alone.

Keep the area clean and thoroughly dry, wash hands after touching it, and avoid sharing towels, clothing, hairbrushes or sports equipment. Follow the directions for [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) and continue for the advised course; stopping as soon as the itch eases can allow infection to persist. Do not apply steroid cream alone unless a clinician specifically advises it.

Take a clear photo in similar lighting so changes are easier to judge. If the area is extensive, recurrent, on the scalp or nails, or not responding, a clinician may consider [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/).

Arrange medical review if the rash keeps spreading, becomes painful, develops pus or crusting, or has not begun settling after the advised treatment period. Seek prompt care for facial or eye involvement, scalp hair loss, or widespread infection. People with reduced immunity, diabetes, or a young child with a suspected infection should seek advice early.

Could this be ringworm or another cause of scaling? Which treatment suits this body site, and how long should I use it? What signs would show that the infection is active or needs a different approach?
