Red, itchy, ring-like rashes are most often due to a fungal infection, where the rash spreads in a circular pattern because of fungal growth on the skin. This usually happens with sweat, moisture, or sharing clothes or towels. Keep the area clean and dry, wear loose cotton clothes, and avoid scratching or using random creams. A doctor may advise an antifungal treatment to clear it properly, so talk to your doctor if it is spreading or not improving.

A fungal infection on multiple body parts that is not improving may be due to incomplete treatment, resistance, or repeated moisture and sweating. Keep all affected areas clean and completely dry, wear loose cotton clothes, and avoid sharing towels or clothing. Do not stop treatment early, even if it seems to be improving, as this can lead to a recurrence. As it is not responding to current treatment, consult your doctor so the diagnosis can be confirmed and stronger or longer treatment can be planned.
