I Am A 62 Year Old Male, Weight 220. E

I am a 62 year old male, weight 220. E mail address Krafty 40 @yahoo.com. I have had two prior back surgerys and a history of hemroids. I have had a burning sensation, not visable to the eye, for several months between my scrotum and anus for several months. I have been using anti bacterial cream but it has not gone away. Please help me.
