I am a 45 yr old male. I have asthma from birth, and I use Aerius 1xd, Singulair 2xd, Symbicort 400/12 3xd, and Ventolin when needed.
The last two years, whenever I have to cough really hard (the gasping for air kind), I frequently get to a point where I start "dry vomitting". I get a vomit reflex, but nothing comes out of my stomache., I only, explosively, force a lot of air out of my lungs. Directly after that I get an excruciating pain all over my upper body; chest, back, neck, sides and back of my head, arms, and hands. Like there is a few hundred Volts running through me. I've passed out a couple of times because of it. It takes about two hours before the pain's completely gone. What's happening, is it dangerous, can it be prevented?
