That's pretty common. And the movement of the nerve would certainly fit with the sensation the OP is describing.
That study also found that while the ulnar nerve was about 3x2 mm in men, in those with a hypermobile ulnar nerve the nerve was usually somewhat larger.
A flexbar really helps prevent tennis elbow??
