Thanks for your replies!
I only take benadryl as it is something im not afraid to take. i also carry an epipen. My spirometry readings were low but i cant remember what they were but they know i have a restriction. that was over 5 years ago. my oxygen levels are always about 99-100 percent so because of that, they insist im hyperventilating. My allergist wanted to do allergy shots but im too afraid of that too. sometimes i wonder, even though i have food allergies, if gerd intensifies the shortness of breath. it's very frustrating to have to focus on every single breath.
no i haven't had that test. in fact, this is the first time i've heard of it. i'll research it because i didn't know there was a way to diagnose asthma except with a stethoscope. I think i might need one of those tests. i'm afraid of dying during my testing - even at the hospital.
