Dermatographism: Dermatographism means the ability to write on the skin. People with this form of chronic urticaria are sensitive to touch and pressure, as well as scratching. The areas of skin that are touched or scratched get a raised, red and itchy rash. While many people with chronic urticaria have features of dermatographism, people with true dermatographism have only pressure as the cause. Try antihistamine.
Dr. John Chiu

Allergy consult: The issue is complex and you should consult an allergist. Do realize that even though we can usually control the rash, not uncommonly no cause can be found despite exhaustive studies. In the meanwhile, try taking antihistamine 3 to 4 times a day to see if this may help. The dose needed for itchy skin is much higher than what is needed to control hay fever but even then it may not work.

Need evaluation: Diffuse itching of the body is called pruritis, and can be due to impairments of the liver and ducts draining the liver. A primary care doctor would be the best place to start, if you have yellowing of the skin, or of the whites of the eyes or pain under the right side of rib cage then see a gastroenterologist. If liver is fine, then see allergist or dermatologist.
