Yeah, I had allergies, I went for the needle test on the arm, and they told me I was highly allergic to rag weed, roaches, and bed bugs. No problems with the last two, but rag weed I can snort and have no reaction what so ever, but If I get it under my skin then I have a problem. So I figured it out myself, it was the tree in the backyard, I cut it down and no more allergies ! It would put me in the hospital in 15 minutes with allergic asthma, almost bit the farm one time, went through that for over twenty years.
Yeah, they gave me all kinds of meds. one almost killed me, but they couldn't figure out what was giving it to me. that told me, they don't know how to cure it, they just give you a broad array of meds. and hope it works.
Not knocking all doctors, just the chemical administering ones.
P.S. Good luck, hope you get it cured, it is miserable.
