Since a car accident about four years ago, I have had terrible pain in my left shoulder (I was the driver, and it's right behind the seatbelt location). It feels brusied, although there is nothing visible. And there is swelling; tingling also on left pinkie and next two fingers, as well as burning in elbow. Nothng much shows on an MRI. What kind of doctor should I see? Have seen orthopeadic surgeon. What could this be? It's been so long; sometimes heat helps, sometimes ice pack. Gets much worse with lifting/arm stretched, etc. Thank you!
