I have this pain that started in my right side of my back since September. And now than the last few days the pain is shifted also to my left side in my lung area. And pain in my chest on the left side that goes down my arm and feels like somebody is squeezing my veins. I had an EKG done and that came back normal. Doctors don't seem to know what is wrong with me and I'm starting to lose hope. When I had an xray done it showed scarring in my right lung that I have no idea why is there. Any help would be greatly appreciated.
