Rashes On Body, Facial Swelling. Taken Benedryl. Blood Test Negative For Allergies. Treatment?

My husband has rashes all over his body. They go away for a while if he takes benedryl but they come back. He went to one of the Eye, Ear, Nose and Throat clinics and they charged us hundreds of dollars and ran tests and told us it would take 2 weeks before they would have the results back and we would know what was causing the rash, but when the test results came back they said he wasn t allergic to anything. At this time his face is very swollen. It is very frustrating.

Dermatologist 's  Response
hello
Thanks for posting your query.
Your husband must be suffering from chronic urticaria. most of the cases belong to idiopathic category. That is difficult or cause not known. He must take anti histamines like benadryl or the latest non sedative like levo cetrizine one tab per day and if he under good control which means rash free for 24 hrs. he can continue the medication for few months before he stops. he may not need for more than six months.
there is nothing to worry.
meanwhile you can avoid egg, fish, fish products etc and check if it helps
have a good day
