Well i have a few problems , health wise .. i've been having what's seems to be symptoms of (hives ) been on and off for atleast four months !

Hives: Hivea can be stimulated by exposure to allergens or other environmental causes but a work up is warranted because in some cases anaphylaxis can occur which can be dangerous or life threatening Recommend consulting with an allergist

Hives: Urticaria. Usually the cause of chronic urticaria (if that's what it actually is) never gets found. I think it's often an antibody against some component of the allergy part of the immune system. Tried a food diary? Or you might try an elimination diet (maybe rice, lamb and a vitamin tablet) for a month or so, and if it works, reintroduce foods one at a time. You might discover the cause.

Mostly idiopathic: meaning no known cause to science so far, but in few cases could be due to other hidden cause, hence you need evaluation by a specialist, either an allergist or a dermatologist, if you are taking any antihistaminic OTC, (recommend the less sedating second generation ones), take them on regular basis even if you don't have the symptoms, for better control,till sorted out by the specialist,
