Hello Doctor, I was diagonised for Symptomatic Demographism, not sure if that is right. The problem i have is, i started to get rash now and than. It comes and goes in 5/10 mins. It is like hives . what could be the orginal cause since i was given allegra 180 and i am having it for past 10 days, but still i see the problem.
Hi, The problem with dermatographism is that most of the time there is no specific cause for it. However, at times hot baths, stress, anxiety, exercise and skin friction(rubbing, scratching, minor pressure over skin) can flare it up. The disorder usually goes into remission on its own, may be in few days, or it might take few years to go. So the only thing that can be done is to take antiallergics to relieve the symptoms. As you said with Allegra you are not having much of response, in that case you can consult the doctor to add one more group of antihistamines. You can also apply soothing calamine lotion, it will reduce the itch to some extent. Take care.
