Hello Dr My chest feels tight, heavy and painful, I have difficulty breathing more like I struggle to get enough air. I have to constantly take deep breaths or yawn trying to catch air. My throat feels swollen and painful from the outside. This happens seasonally. Also whenever it happens, my eyes feel like they are popping out. I ve done thyroid tests 3 times and they came back clear. I ve gone to doctors since 1998 for this and to this day, I have no solution. What could be wrong?
