I've just come across some info on an allergy treatment that sounds interesting to me, and it occurred to me, without knowing much at all about your medical history or condition, that it may be of some interest/benefit to you since the standard medical treatments don't seem to be helping. I don't know if you're open to or interested in alternative methodologies either (and there are LOTS of them!), but I thought I'd go ahead and drop this into your "information box". It's called NAET -
From Wikipedia: Nambudripad Allergy Elimination Technique (NAET) is a non-invasive, drug free, alternative therapy intended as a treatment for allergies and chemical sensitivities. Founded in 1983 by Devi Nambudripad, a California based acupuncturist, NAET draws on ideas from acupuncture, applied kinesiology, and allergy medicine. NAET is practised by over 9000 licensed medical practitioners all over the world.

We now know that most illnesses (i.e.headaches, back aches, joint pains, addiction, PMS, indigestion, cough, body aches, etc.) are caused by undiagnosed allergies. When left untreated, allergies can become serious life threatening illnesses. Please read "Say Goodbye To Illness" by Devi S. Nambudripad, M.D. (WI), D.C., L.Ac., Ph.D. (acu) to find the cause of your illnesses.
The brain provides warnings to the body whenever blockages occur within the energy pathways. These warnings include illness, pain, inflammation, fever, heart attacks, strokes, abnormal growths, tumors, and various physical, physiological and psychological discomforts. If the symptoms are minor, blockages are minor. If the symptoms are major, blockages are major. Minor blockages can be unblocked easily, whereas major blockages take a long time to unblock.
Dr. Nambudripad's discovery, NAET®, is an innovative and completely natural method for regaining better health with often permanent freedom from allergies and the diseases arising from those allergens.

Google NAET, as with all alternative treatments there is some positive info and also some calling it a scam, so you can evaluate.
