I have it.! Not the worst thing really. by: Anonymous
I have had Dermographism since I was a kid (for about 25 years). I have no idea how it happened. The only thing I remember is that one day after bath time all my body was red and covered in welts, but it went away as soon as it came. Sometimes it is annoying when you wear short sleeves and people notice welts on your hand and ask you what is wrong. I don't wear shorts anymore because of all the objects that touch my legs and cause the welts.
Other than that everything is fine and I have also learned not to put pressure on my face or neck while sitting. I chose not to take medicine because I don't like the drowsy feeling allergy medications give me. It is not a terrible disease and with some adaptation you can definitely live a normal life.
