Long-term management for chronic dry, irritated skin.
Fungal Infection

A highly contagious fungal infection caused by dermatophytes, often spread by skin-to-skin contact or shared items.
Keep skin clean and dry, avoid sharing towels or sports gear, and wash hands after touching pets.
Topical antifungal creams (clotrimazole, terbinafine). Oral antifungals for stubborn infections.
Myth: It is caused by a literal worm under the skin. Fact: It's caused by a fungus. The name comes from its ring-like appearance.
If the rash doesn't clear up after 2 weeks of OTC antifungal use, or if it's on the scalp.
