This is a long story, so please bare with me. I fell while playing tennis one day and scrapped my knee pretty bad, and since I didn't wash it enough, I guess it got infected. So my doctor prescribed Doxycycline antibiotic. The infection cleared up very quickly, but I continued the dose for 10 days. On the last day, a small red bump on scrotum that freaked me out, so I went to urgent care and the doctor said it was an infected hair follicle and prescribed Bectrum DS for another 10 days. That's when my problems started. I noticed skin lesions on both sides of the shaft on my penis. They didn't hurt, but when I touched them, they would itch. I didn't like this to Bactrum, so I continued the dose. By the end of my trial period, I noticed more lesions. I tried to rub them out, but they got more irritated and more reddish. I went to another doctor who prescribed one dose of diflucan and Lamisil. Diflucan 150 mg seem to take all the irritation out, but left the skin very chapped and scaley. After a couple of days, the redness came back and now I have this reddish irritation also under the tip of the penis. So another doctor prescribed diflucan 100 mg for 7 days + Lotrisone, which is apparently a combination of two medicines. I'm on day 4, and the symptoms don't seem to be improving. I'm 27 years old; I'm not diabetic, and never had actual sexual intercourse, but did get a few hand jobs before. I finally went to a dermatologist who thinks it may be a viral infection so he took a culture sample, but won't know the results for another week. Any idea what could it be?
