10 Causes of Urticaria
Cause #9: Friction
Some portion of the population have a condition that is known as dermatographism. This is a condition in which patients are hypersensitive to friction.
In people with this condition, rubbing or scratching the skin can result in the emergence of hives. If the hives are continually rubbed or bothered, they will generally continue to get more intense. Wearing loose clothing and avoiding heavy physical contact is the best way to limit these break outs.
