i feel as though i cannot exhale completely. I can breathe in fine but on exhale my chest hurts and the deeper i try to exhale the harder it hurt. The pain is where the sternum is and is just that area. Because im  not exhaling fully i start to hyperventilate. If i exhale hard for half an hour or so the pain subsides but if i dont exhale then i cant concentrate, get rapid heart rate along with palpitaions, fatique, muscle pain, back pain.

The breathing excersize are helpful but iv had this for a few years now and am beginning to think it needs something more than self therapy. Is there anything i could do to ease the pain in the chest which is what i think is causing all this.
