Hi Kay,Sorry to hear you're having trouble. From what you're describing, it sounds as you vocal cords are the source of your breathing issues. There is something called, Vocal Cord Dysfuction. With vocal cord dysfunction, the vocal cords can get in the way, and can make it hard to get air past. Here is a link with information:
www.nationaljewish.org/healthinfo/conditions/vcdOn the left side of the web page, there are topics related to VCD, for you to click and explore.
Have you been to an ENT or pulmonologist/asthma doc to be checked? Your symptoms sound bothersome enough to warrant medical attention.
Good luck with your search for answers!
Best wishes,
Denise
