Advice support symptoms and conditions

I took 20 mgs a day for 5 days in September of 2006. I developed a terrible cough, but worse than that, severe chest pains & shortness of breath upon exertion. I still can't go up & down stairs; my pain is brutal and it's going on 3 years since it all began. Before I took the lisinopril, I hadn't been having any chest pains or trouble breathing.

Is there any hope of recovery? My doctors all say they've never heard of this kind of side effect; that lisinopril is a very common drug; it's clear that I have reduced lung function & definite pain & symptoms, but there is no way to isolate the exact thing causing it or to figure out how to make it go away; just to control the symptoms.

My theory: the lisinopril triggered an autoimmune response in which my body physically tries to reject my own lungs. Any thoughts on that one? I had been taking cozaar as an ACE inhibitor to slow the rate of my renal failure; I have type 1 diabetes and hypoparathyroidism, and while I needed meds before this episode, all I had to do then was manage my diabetes & I was able to live normally. Since this, it's been nearly impossible to do ANYthing. I am at the end of my rope & I want this to stop. But 3 years later, and while the shortness of breath is improved, the pain is actually worse now. I could sure use some advice & support. I'm on my way this week to get set up with a new dr. because we've moved, and I'm going to have to go through this whole thing again. Also - I'm trying to compile a list of other people who have had side effects with chest pain & shortness of breath. Also anxiety & panic attacks as collateral damage.
