Does weight training cause nerve issues in the hand?

Hi doctor,

For the last couple of years, I have had some tingling in my two little fingers and my elbow. I also have upper arm tenderness. I started weight training and used to do a lot of triceps. That is what started it. I have had an MRI of my neck and spine, and it was clear.

The pain is not bad. However, I can often feel the tingling, and if I gently rub inside my upper arm, it sets off the tingling. I had a nerve conduction study, and the woman in charge was not very good at communication and, frankly, had no time. She said there was a slight entrapment (I thought it was either trapped or not trapped). There was not any obvious popping when I flexed my elbow.

What would you think and suggest needs to be done?

Thank you.
