Red, circular, itchy patches on the skin are commonly seen in fungal infections like ringworm, but similar-looking rashes can also happen due to eczema, allergy, or other skin conditions. Fungal rashes are often round, itchy, slightly scaly, and may spread slowly over time. Keeping the affected area clean and dry is important. Avoid scratching, sharing towels, or using very oily creams, as moisture and irritation can worsen the rash. Wear loose cotton clothing and change sweaty clothes quickly, especially in hot weather. A doctor may suggest an antifungal cream if it is truly a fungal infection, but the correct treatment depends on the exact cause of the rash. Medicines/treatment should be taken only if advised or prescribed by your doctor. Avoid using steroid-containing creams on your own, because they can sometimes worsen fungal infections and make diagnosis difficult. Please see a dermatologist if the patches spread rapidly, ooze fluid, become painful, affect the face or scalp, or do not improve within 1-2 weeks.
