I am 40yrs, started itching in my later 20's. I have had this condition for about ten years. I am not fair skinned. I am african american, medium brown, someone remarked that fair skinned people tend to have this. I do know two light skinned african american women with this same condition.
I find it annoying: when getting eyebrows arched, taking showers, my lips use to welt up, if an itch pen grazed my face, people looking at you crazy, my upper chest looked like a cat clawed me...etc..
I have been prescribed Doxepin( an anti depressant) I take it only once a week and it does the trick. Doxepin doesn't work for everyone . I also take Xyzal (allergy med, prescription only) 2 or 3 times a week. I itch just very little, but nothing embarrasing like before and hardly any welts.

I use to be able to play tic tac doe on my skin! I recently met an older gentlemen 57yrs- he has been prescribed Lyrica, he has relief after 12yrs and he was so glad to find out that he wasn't crazy that there is a whole community with this issue.
