Over a month ago, I got an uncomfortable rash all over my genital area. It went away after a week or so. I had been having several instances of weird genital skin stuff, so I was tested for a few STDs--HIV, Syphilis, and Herpes I and II, all of which came back negative.
Then, two weeks ago, I got an itchy rash that started on my wrist and then spread to my pelvic area--it was particularly concentrated around the front of my waistline. This rash went away. And then, a week later, I developed itchy, pimple-looking bumps on my chest. These too were clearing up when I woke up with several red, itchy areas on my penis and testicles. It was itchy. There were also some bumps around my belly button and one on my nipple that itched as well. I went to the doctor, and he said he thought it might be scabies. He gave me some medicine and a shampoo, which I will use, but I have my doubts about the diagnosis, given the ebb and flow of this rash.
I have also had a small, raised, slightly hard area on the rim of my penis, which no dermatologist (I've seen 3) has been able to identify. The inexplicable hard bump has been there for 4 months, ever since I moved to Central America.
Can anyone make sense of all (or any) of these things?
Thanks.
