Nerve injury from blood draw

A year ago I had my ulnar (or median but pretty sure ulnar) nerve hit during a blood draw. The first 2 months it felt like I hit my funny bone constantly and was told to not use it and it would heal itself... Now the pain has traveled up my arm through my shoulder and neck to the back of my head behind my ear and making my left side of my face feel 'weird'. It goes down my forearm mostly to ring finger in the other direction. I've had a MRI on my elbow and neck and also nerve conduction test on my arm, all which couldn't find anything "significant". I've been told to see a neurologist but don't want to see the one I already saw b/c he diagnosed me with tennis elbow and didn't run any tests so don't trust him. Thank you for any help.
