Hello,
From the symptoms it sounds like
ring worm or fungal infections. Wash your
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.
