The study above used ultrasound to see how many people in the general population had an ulnar nerve that moved from in back of the protusion of the inner aspect of the elbow (the medial epicondyle) to around the side of this bony protrusion and end up slightly more on top of the elbow area. This study found that 1 in 5 people have an ulnar nerve that moves like this. No one needs surgery just because the nerve moves like this. It is just a pretty common variation from the usual behavior of the nerve to stay in back of the inner bony protrusion of the inner elbow (medial epicondyle) as the arm is flexed and extended. It may be that doing all those curls may cause some nerve irritation from it's moving, but you are juming to conclusions that this is your problem if you have not been examined medically.
I did not intend to cause you any worry that you need surgery.
A web site is not a place where you can get any definitive diagnosis or treatment. If the arm is continuing to bother you, you should be checked out medically.
(You do know that it is the triceps and not the biceps that is the important upper arm muscle for tennis, don't you? And that if you are interested in a set of exercises to help prevent injury while playing tennis, you should be doing the thrower's ten: www.asmi.org/SportsMed/throwing/thrower10
