Thought I may have been having problems with ulnar nerve. Started out with tingling in right arm, palm of hand, and 4th and 5th finger. But, now feeling tingling traveling from center of chest to right shoulder and tingling in right arm, palm, and 3rd through 5th fingers. Can ulnar nerve affect chest also. My right shoulder has been frozen for some time (therapy did not help) and upper right back is tight and painful.
