Sometimes this condition is referred to as dermatographism, which literally means skin writing, since bumps appear on the skin when it is stroked, scratched, rubbed, and even slapped. These welts tend to remain on the skin for sometime and then disappear. However, at times, these may stay longer than a week. In such a case, a visit to the dermatologist is essential.
