Well, thank you for bringing that up. I'm a musician and so usually have these chronic hand problems. so when you mentioned this i looked up ulnar neuritis. Sarcastically, I am the proud owner of some of the most tense neck and back muscles among my friends and pals. this is what I found , a snippit , about ulnar neuritis:

It is my opinion that most ulnar neuritis, but not all, originates from a traction injury of the ulnar nerve at the shoulder by the muscles at the back of the shoulder


thank you for bringing it up. I should get refitted before I destroy my whole body. THANKS !
