Hi, since past two days, m having chronic pain on the back of chest. And left shoulder. Till last night, it was in front side almost whole chest, since morning it moved to only left part behind the chest and the left shoulder. It I bend forward, there bottom edge of chest pains. Breathlessness. Coughing. But not able to cough properly due to severe pain. Can't lie down straight out upside down. Only able to lie down on the same left side where pain occurs. Getting confused due to several indications. Please assist. Thanks in advance.
