About 2 % to 5% of the population is affected by dermatographism, also called dermatographia or skin writing. This condition, which is not dangerous, causes welts when skin is scratched, rubbed, or otherwise exposed to pressure.
Why do I suddenly have dermatographia?
When people who have dermatographia lightly scratch their skin, the scratches redden into a raised wheal similar to hives. These marks usually disappear within 30 minutes. The cause of dermatographia is unknown, but it can be triggered in some people by infections, emotional upset or medications such as penicillin.
Does dermatographic urticaria go away?
Symptoms of dermatographia usually go away on their own, and treatment for dermatographia generally isn't necessary. However, if the condition is severe or bothersome, your doctor may recommend antihistamine medications such as diphenhydramine (Benadryl), fexofenadine (Allegra) or cetirizine (Zyrtec).
