About a yr ago, I developed tendonitis in the rt wrist ( according to a doctor). I thought it had healed. Next thing I saw was a cyst , a fatty area near the ulnar head. After that, I experienced pain in the hand, went back to the doctor and he X-rayed the wrist. It showed osteoarthritis. After that, I began losing sleep due to numbness and tingling in my rt lower arm...up to the wrist. Also, I think I feel a little pain in the upper back, perhaps around the T-1 level. What is going on, is my question? And how do I sleep if I get numbness in the arm after a few minutes of lying down?
