Hi. I have been suffering with a breathing problem since mid last year. I was struggling to take a deep breathe. Always needing to take a deep breathe and not feeling like i was getting air. I have had many appointments with doctors and xrays and tests which all confirm that my blood is getting more than enough air. It seemed to improve slightly over the past few months but it has since come back slightly and i have noticed throbbing pain near my left hand colar bone. Could this be something to do with the breathing problem?
