Dermatographism: Welting of the skin immediately following rubbing is called dermatographism or dermatographic urticaria (medical word for hives). It suggests that a cell population in your skin, called mast cells, are releasing histamine. It is seen in 4-5% of people. In most cases a cause is not discovered. If it bothers you, try antihistamines like zyrtec or Benadryl (check interactions and contraindications). ...Read moreSee 1 more doctor answer

If it bothers you, try zyrtec (get the generic) 1 or 2 a day. No blood tests or allergy tests will help you. ...Read moreSee 1 more doctor answer
Dermatographism: When the skin is scratched, a hive develops. Most cases happen for no known reason, although it can be seen after one gets an upper respiratory infection, a medication, or collagen vascular diseases. Again, most common it comes for no known reason. Treatment is simple--take antihistamine every day (i.e. Zyrtec, claritin, allegra). Most will resolve with this. Take for 3 months and try stopping. ...Read more
