For about 5 years I've had recurring pain under the medial section of my left shoulder blade. It is not constant, it seems to come and go, but every time it recurs it seems to get worse. It is not a sharp pain, more like a deep burning. Within the past year, during times when my shoulder is acting up, I also experience, pain, numbness and tingling in my left arm and hand (particularly in my pinky and ring finger), and my shoulder joint has begun to pop and catch.
