Strange rash wherever I scratch

I have a strange condition and I have no I idea what to do about it. Wherever I scratch myself, be it on my leg, my arm, my neck, wherever, in the exact spot where I scratched, I break out in a rash or a hive or something. The rash doesnt hurt or itch or anything, but it looks unsightly. Can anyone tell me what might be causing this, or a treatment?

Hello,
It can be due to dermatographism and urticaria. Dermatographism can be caused by stress, tight or abrasive clothing, watches, glasses, energetic kissing, heat, cold, or anything that causes stress to the skin. In many cases it is merely a minor annoyance, but in some rare cases symptoms are severe enough to impact a patient's life.

It can be treated by antihistamines or cromoglicate and sometimes steroids, as they prevent the histamine from causing the reaction. As the underlying cause of dermographism is not known, it can last for many years without relief.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
