In my anus region, there is a tiny sentinel bag of less than 2 mm and nowadays I feel wetness. I am aged 76 and taking BP drugs carvedilol and amlong once daily, with ecosprin. The surgeon advises a small surgery for which he will administer spinal anaesthesia. Need I go for the surgery? I am presently putting ano metrogyl cream. I wd like to be clarified wh post surgery situation will improve this present embarrassing situation.
