Hello,
For ringworm(fungal infection),wash the effected skin daily and then dry thoroughly by pat drying,not rubbing. The damp skin is an ideal site for fungi to multiply.Also wear cotton underwears and change them twice a day and do not share other people’s towels.
Most cases of ring worm respond to over-the-counter products, which contain any of several basic ingredients: miconazole, tolnaftate, terbinafine,ketaconazole and clotrimazole.You can consult a pharmacist and get any cream or lotion containing these ingredients. Some of them are Lamisil, Monistat derm, Mycelex, and Nizoral.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
