Hello,
You are suffering from
excessive sweating of the rectum area. It commonly occurs due to exercising, wearing tight fitting fabrics, stress, medical conditions like
hyperthyroidism,
fungal infection, pruritis-ani, etc. You are suggested to take a wash every time you visit the washroom. Be quick to change the undies, do not wear undies in which you have already sweated.
Manage stress and get tested of thyroid, get T3, T4, TSH done. You will be accordingly treated. Take care of your hygiene. Keep your private area clean. Use antiperspirant. If fungal infection, then you should apply ointment
clotrimazole on the area affected for relieve.
Pruritis ani will be reduced by applying
hydrocortisone cream on the area affected. Keep the perianal area clean and dry. You are suggested to avoid the use of harsh chemical soaps, perfumed lotions, soaps, beauty products.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
