Steroids will torture you and destroy your immune system. Antihistamines and H2 blockers like Zantac will provide barely any relief and never solve your problem. Meds do nothing. Blood tests will tell you nothing because the cure is not in your bloodstream – it’s in your gut.
Two words that gave me back my life: DIAMINE OXIDASE (or DAO), which is a naturally occurring enzyme in your gut. It breaks down histamine and flushes it from your system. It is not patented, so your doctor will never tell you about it (if he/she even knows about it) because you don’t need doctors to cure your problem (in my opinion).
Antihistamines merely coat histamine, so even when I feel some relief, those cells are still communicating (ie, your curing nothing). When you don’t have histamine in your system, those cells simply stop acting on the circadian rhythm which perpetuates your condition. Worst year of my life, but I did my research and found a supplement that supplies DAO; and immediately my hives decreased. Slowly I reintroduced foods I had abandoned, and within a month of consistent DAO, they were gone–never to return.
I don’t want to recommend a specific product for fear of appearing as spam. I genuinely just want to help people find relief from this torturous condition. You can buy it on Amazon. I’ve checked the drug stores and GNC/vitamin shops – they don’t have it, but you can search diamine oxidase and/or histamine and get a supplement. I used 20k IU’s of DAO, and my hives (and doctor bills) are DONE!
