I had hives for eight years as a child growing up in Northern California. When I moved to Masschusetts for college, they went away. And they stayed away until 2005, when they returned. I have had them since then. Except, after I was on Zyrtek, Singulair, Zantac (H2 receptor) and Doxepin...then later Hydroxcicine...I found, though trial and error, that if I had one Zyrtek in the morning and three of this digestive supplement Vitalzyme X, then I didn't have them. If I missed a day with one of these two substances, they would come back.
This summer, somehow the combination stopped working. They did change the Vitalzyme formula from X to XE but I don't know the reason; taking it doesn't work any more. So I'm back on the heavy anti-histamine regiment including Zyrtek and Hydroxicine. My doctor wants me to go on steroids but I remember clearly that when I came off steroids, then my hives were worse than ever.
I have them everyday, all over including my face. Luckily, they plague my lips but rarely my breathing. Does anyone see a common thread? Like having Diabetes (Type II), eating heavy proteins, eating wheat (Celiac-like some mentioned), not eating wheat, heavy exercise, no exercise, having had liposuction, any common thread?
