Hi, I am 16 years old and have problem with scratch on elbow. My doctor said that I have dermatographism. Anyone please tell me more?

Well, the Dermatographism is a form of urticaria in which skin welts develop along the lines where one has been stroked or scratched.
Dermatographism is a condition where lightly scratching the skin raises wheals or welts. Histamine is released at the site, causing the small blood vessels (capillaries) to dilate, producing redness and localized swelling.
Therapy is antihistamine but rarely it may be partially efective.
