You can use the site search for elbow pain, I know there are past posts , I had that inner elbow pain too...
Does dr have any ideas on why your nerve keeps popping out?
the groove too shallow ? nerve too tight along the path somewhere?

Part of my cause of mild chronic TOS /RSI was hyper mobility & repetitive production work..

I had good luck with a very skilled chiropractor..used many PT modes of therapies too.. like top rib mob, trigger points, low level laser, US , E stim, adjusted arms, shoulders, elbows, wrists, as needed..
Had lots of PT too, but chiro was faster & more all over wellness focused.
