Two months ago, I had bumps on my penis head and shaft, scrotum, buttocks (mostly in the crack and underwear line), wrists, hands, fingers, ankles, and toes. The bumps were red, and different sizes from pin head size to 1/4 of an inch. The bumps all itched - tremendously. At night, I itched all over, even where the bumps were't.
Because of my lifestyle, the doctor thought they looked like chigger bites, and treated me for the same. After about a month or so, they went away.
A few weeks later, my sex partner broke out with the exact same symptoms, and is being treated with antibiotic.
If I had to guess, I would say this looks more like a viral thing, but it has us worried. Can you give us a clue?
The next step, according to the physician, is a dermatologist and a biopsy.
