Herpes lesions can occur anywhere on the penis. It could cause muscle/joint pains, but probably not. You need to see a health provider immediately. If "as soon as I can" means more than a couple of days, it will make it very hard to properly diagnose your penile lesions.
One more thing I forgot to mention, the muscle/joint pains have seemed to intensify, would this be a symptom of herpes?
Thanks for the advice doc! The "ulcers" (or small tears) appear around the penis head, under the edge where the head meets the shaft. Does herpes usually show up there? I will see a doctor as soon as I can.
Your 5 week negative test result is virtually 100% proof you didn't catch HIV. Your symptoms don't suggest HIV, and Kaposi's sarcoma is a sign of late/advanced AIDS, not ARS. The odds of catching HIV from a single exposure like you describe are extremely low anyway. Genital tingling of the sort you describe does not suggest HIV or any STD; the most common cause of such symptoms probably is genitally focused anxiety. As to your penile dry skin, I would think nothing of it--but I'm concerned by your mention of an 'ulcer' (on your penis?). That raises the possibility of herpes.
Bottom line: See a health care provider if you remain concerned about your symptoms, and especially see a provider if you have a genital ulcer. You can have another HIV test if you want, 6 weeks or later; the 5 week test is almost 100% reliable, but a 6 week case will nail it down for sure. So just relax about HIV; no chance.
Good luck-- HHH, MD
