I have a righthand chest pain and a righthand back pain in behind the shoulder blade. When i stand up and walk around, it hurts. When i take a big breathe it hurts, even normal breaths when im sitting or standing it hurts. When im lying down, like i am now, theres no pain. I use a cpap machine, sleep apnea. I also have asthma, copd, hypertension and cholestrol which is all under medication.
