Hello, Welcome to health care magic. I am Dr Alok Sinha, MD Psychiatry from India. I can understand your concern. I will try my best to answer your query. I have carefully read your question and could understand that that you apparently having a fungal infection. Fungal infection of thigh, groin and genitalia are very common, specially in a hot & humid climate. It manifest with soreness of skin, cracks, burning sensation at the site, itching and/or annular lesions. Skin folds like groin, fold between thigh and scrotum, base of penis etc are the usual sites which remain wet due to sweat, hence more vulnerable to infection. If a person like you comes to my clinic, I advise to do the following:- - keep the area dry - don t rub or wash frequently - wear loose undergarments - sleep naked below waist for few days under fan at night if adequate privacy is available. I also prescribe them some topical antifungal powder to apply at day time and antifungal cream to apply at night along with antiallergic medicine like levocetrizine for controlling the itching sensation. You may follow the above mentioned advise and visit you doctor for further examination and prescription. I hope it answers your query. I wish you all the best.
