From time to time I experience skin sensitivity. It feels like the nerve endings are sensitive, almost like a sunburn might feel.
it goes away after a couple of days, but comes back from time to time???
I had exactly what you describe the last two days over the right side of my abdomen...it even felt burnt and unbearable to touch the skin. I've read it can be a symptom of fibro and that some people have it so bad they can't bear the feeling of clothes on their skin. It's worth getting it checked out by a doctor though, especially if you have any other symptoms too.
sure sounds like your system is inflamed... hope someone has some more clues for you... in patchy areas, or all over?... you on medication? find a good gp who's thorough and start a batch of tests to eliminate possible causes...
