For about 2 weeks now, I've had 2 spots on my body where the skin is very sensitive to the touch. The best way to describe it, is that I almost feels like a sunburn. There is no rash, no redness, or anything else. The skin looks completely normal. It started in my left armpit, shortly after shaving, so I ignored it at first assuming it was razor burn. The area has spread now and covers the full armpit, and works its way into my arm, and around the back to my shoulder blade. It has also started on my left hip and the area there is getting larger as well. I've been getting shingles since I was in my early 20's, but never in these areas, and none of the times I've gotten it have felt like this. It is JUST the skin. If I actually press on it, there is no pain, but if my shirt even lightly brushes against it, there is a lot of pain. Any suggestions?
