I have been suffering from hives for over 30 years with a remission from severe reactions for 25 years now I am back to every few weeks break out from moderate to severe now. With the facicial break outs I have headache to migraines. I have had test for allergies and have changed diet to no change and have even had a hive reaction at blood test sight so feel can get false allergy testing because of this. I have had better control on my own by taking an antihistmine daily and have only had two bad lip break outs in the past four months and only a dozen or so minor break outs on body. I have a finiacial hardship so Im just need to find a limit on antihistamine level to help control the more intense break outs of the angodiema on my face with the onset of migraines. My allergist has referred me to a dermatologist and I'm still waiting for a call four months later.
