Starting early this year (around April), the skin above my left eye start to frequently ich.

Through then till now, I first had a case of Staph infection on my chin and crotch area. Then a few months after that I had Jock Itch.

Soon after the Jock Itch disappeared, the eye itching worsened. Now it seems to have moved to different body parts. The areas are characterized as being dry and/or inflamed, irritated, and sometimes have bumps. I don't know if this has any relevance, but even though the itching may not be to bad or even noticeable, itching known spots causes a slight euphoric sensation in some cases. Current effected spots are the back of my right hand, under chin, both eye lids, forehead, back of neck, and crotch region.

I've had a rapid increase in body weight, as well as a increase in hair loss off my sculpt.

I've had myself tested for sexually transmitted diseases - that came out negative.
I've had myself tested for diabetes and thyroid issues - also negative. Both do run in the family - especially my mother's side.

I've used cortisone, but that only relieves the itching. Allergy pills don't help much. Started using Selsun Blue on my sculpt due to drandrif.

What is wrong with me?
