Exactly what I had a few years ago, my left shoulder was in pain, I had pain with upper arm, I also had tingling with fingers. I took X-ray, I met a couple of doctors, they all said I was fine. I told one of them that hot compress helps a bit, she said then you do hot compress as long as it helps you. Then I decided not to see any more doctors throwing money, so I started my gym training. That actually helped more.
