I have had this problem for a couple of years. What the Dr. told me ,was it was a form of herpes and gave me acyclovir. What i noticed, is that when i get extremely stressed it starts itching on m buttocks, on one side in the same sport all the time. I gt some anti fungul cream and learned to control my stress. i now rarely get a repeated problem. i can;t think of the crea i pruchase right now, but it comes in a little tube and costs about $8.00.View Thread
