Understand, as my journey was 91/2 years to find solution to SOB with minimal exertion. Only last year did I developed SOB like the hyperventilating. Good news is that my first problem was solved by ACDF surgery with a herniated disc being removed and a spacer put in C5/6. The other SOB like yours is still there, and I’m beginning to wonder if it isn’t a pinched nerve at C4/5… Maybe have an X-ray?
