So fr the antihistamines and meds. I was on daily Flonase and Sudafed in conjunction with Zyrtec, this offered little to no relief. I have tried aleve and other meds and they never seemed to help much. For the nausea I have found that a certain "herbal" remedy was the only effective solution at times even when I was taking the sublingual medicine (sorry I can't recall the name but it is the most common out there). The allergists and I believe that all these problems are being caused by an autoimmune problem but to paraphrase him there is no treatment currently available so there is nothing that can be done until more research is available. When I visit other specialists for immunology or rheumatology they just tell me to keep doing what I am doing which is nearly completely avoiding the allergens. The rheumatologists at the Spectrum Health clinic were not helpful though. I was provided with the product information for four medications and instructed to pick one. I tried half of them and they caused significant side effects such as skin burning and pealing. A third had nearly killed my sister, and the fourth was terrifying and even taking it for a short time was potentially going to cause decades of side effects. The rheumatologist had stated to me that these were "the only" medications available. They refused to do any form of testing or examinations, which made no sense to me.
