Dermographism means “write on skin” and it is the most common form of physical urticaria in the population. It is estimated that 4-5% of the population are affected. This condition is quite benign, and the patient should be reassured upon diagnosis. It is not known what exactly causes this condition, and it may last several months to years before going away. Treatment includes antihistamines and avoidance of physical stimulus of the skin that can cause the urticaria. The person should also be instructed to avoid hot showers/baths as it tends to make the condition worse.
Dermographism can also be associated with chronic urticaria (generalized hives that has been going on for more than 6 weeks). A qualified Allergy & Immunology specialist can help evaluate your urticaria/hives.
