I Have Skin Allergy That Is Urticaria In Which I
Can be dermographism.
Hello dear welcome to Ask a doctor's service.
I read your query and here is my advice.
I think you are having dermographism which is the appearance of urticaria or hives after you scratch the skin. The origin is unknown so there are no specific recommendations for foods or substances to avoid.
I think stress may trigger it so better avoid stress.
Using antihistamine is the only treatment you can use . Allegra that you are using is also an antihistamine and will help you prevent these episodes .
Hope I have answered the question.
Let me know if I can assist you further.
