My penis has a redness around the tip area, and it never use to. I had some small blisters and itching 15 months ago. Dr. s that I have been to said it was herpes. But have not had any blisters for 15 months now. There is no discharge. The itching is like inside the hole, but I do get a very, very, slight itch feeling every once in a while. Not like I use to. I think it is something other than herpes. But the head of the penis gets a funny looking red blotch every so often. I was wondering if tetracycline would clear up this redness. I have been to my general doctor, 2 dermatoligist, 2 uroligist for a total of about 9 times and they can not seem to clear up the redness. What is your opinion?
