Sylvie,

What is involved in the testing? Have you considered just trying the antihistamines to see if they work? Many conditions are actually diagnosed by trying treatments for them...ie., like inflammatory neuropathies are sometimes determined by seeing if a course of steroids work? It's not like there is a specific test for inflammatory neuropathy...and the short course of steroids can show immediately whether inflammation is a factor int he neuropathy.

Speaking of bedridden, what have you tried for your dysautonomia? I don't want to detract from the point on your thread (which I think is perfect based upon some members comments and symptoms). I have a long history of dysautonomia (19 years) and might be able to offer you some information to help you get out of bed.

I am one of the many here with strange allergies, but that is also common with any autoimmune disease, due to the direct tie between the immune system and allergies (IgG, IgA, Igm...& most importantly, IgE (for allergies). So I have an interest in where this topic goes and all the good input that will likely get posted.
