A year ago I began having major pain in my shoulder. After going to my Primary Care they say I had strained my rotator cuff, gave me a list of instructions and said if it wasn't well in 2 weeks to come back. I ended up going back, diff doctor, same result. Now, the pain has gotten extremely worse. I have numbness and tingling down my arm, and I can't lift above my head. It's weaker and I have trouble sleeping at night. What does it sound like? Should I see an orthopedist?
