Hello, I had right rotator cuff surgery just 6 weeks ago, one tendon repaired. After 4 weeks I removed sling and began physical therapy. I have horrible pain and numbness in my hand, a little in my forearm, and some burning pain in the tricep region. The pain in the hand is almost excruciating. I had swelling in the hand, but it is subsiding as I work the hand, the pain,though, has increased. What do I do?
