Hi, I am quite empathetic to your skin problems and can make out that you are really stressed with the situation. After reading your history I can make out two possibilities: 1. Fungal infection of the area: if these are raised ring like areas or map like then this is the best possibility. 2. Allergic contact dermatitis: if these are red areas with complete coverage without any ring like appearance. Do not pinch, pop or scratch the area.Keep the area dry and wear cotton clothes. Change the undergarments two time a day. DO not get exposed to extremes of environment and protect yourself from heat and humidity. For fugal infection, I suggest you to apply plane anti-fungal cream such as clotrimazole or ketoconazole. Take fluconazole 150 mg alternate days or tablet terbinafine 250 mg daily for 15 days. Do not apply any mixed cream or mixed ointments as it causes further aggravation of the problem. If at all the things are not improving in next couple of days after this above treatment then you can meet a dermatologist for best possible diagnosis. Take care.
