Pain usually on ex hailing.Upper left side,under arm to my back & bringing up phlegm. Worried!?

sounds like you have a chest infection, or pleuritc pain from the pain and phelgm. you will need antibiotics, over the counter medicines will not fix it, they do nothing. get to your Dr. or it will get worse. (pluerisy is an infection of in the space between your lung and chest wall.when it gets infected it dries out and causes pain when breathing), it s not life threating, but needs treating)
