Lisinopril and heat cold

I'm a 30 year-old female. I've been on Lisniprol for almost four years. And these four years have been the worst of my life. I've had test after test and seen dr. after dr. trying to figure out what is wrong with me. I have a terrible cough, my face gets hot and I get the chills (kinda like the flu), I'm very achy with pain in my legs and back, headaches, confusion, memory loss, sensitivity to heat/cold, swollen throat, very tired. Chest pain and trouble breathing (wore a heart monitor and had stress test, but everything was normal). Heart rate is rapid. Gained a lot of weight in the last three years. Everything test-wise always came back normal. Saw an OB/GYN to see if I was premenopausal; nope. Had an MRI and CT for the backpain; nothing; Labs done to rule out throid disease; nothing. Saw a neorosurgeon for possible nervous system disease from so much pain. Nothing he could do. Went to allergist for possible allergies; nothing. Oh....but wait..I go to the dr. today to tell him I'm still not feeling better and that I ran acrossed some information on the web about possible side effects of the bp pill Lisinopril and that I still recall that I started experiencing side effects about the time I started the medication of 10mg. Then when he increased it to 40mg, I really felt terrible. He looked back through my labs and saw that an allergan level had been very high in my CBC. He said, "bingo, you must have an allergic reaction, or maybe a perisite". He said this CBC is done on a normal blood test and will show elevation if the body is trying to fight off an infection or has an allergic reaction to something. So...went off the BP pills today. I'll keep everyone posted. My email is ****** if anyone wants to email me with similar situations.
