I have this problem about numbness on the left hand for 2 years already. The ulnar nerve in my left hand feels "pulled" all the time especially when i raise my hand or do anything with it. About 3 weeks ago, i found out 1 of my shoulder is higher than the other one. I aligned it to the correct position and found out the alignment of the shoulder is due to the ulnar nerve. When my left shoulder is higher, it feels normal but when the shoulder are balanced, the sensation of ulnar nerve "pulled" came back. So, I would like to know does anyone has any idea of what I'm being through and what are the treatments. Thanks in advance
