Steve, has your shoulder pain improved after the injections? How old are you? I would recommend going back to your orthopaedic surgeon and telling him/her if your pain hasn't improved.

From what you've said, you COULD have carpal tunnel syndrome, but you it could still be a shoulder issue e.g. a torn rotator cuff muscle etc. It could also be something compressing one of the nerves in your neck that supply your hand.

I know you are probably looking to see a different doctor, but really it's best if you talk to the doctor you have already seen. A neck or shoulder MRI or nerve conduction test may help locate the problem.

Get well soon!
