S.
I have a problem with a recurring pinched nerve in the same place but my left shoulder, from probably the same cause, and I know it's awful. I also thought it might be carpal tunnel syndrome. I do think you should see a physical therapist. 6 weeks of therapy and traction helped me. My PT gave me some stretches to do at home (look down slowly, look up slowly, look left slowly, look right slowly, head sideways to shoulder slowly...repeat five times) and then here's the real kicker: I wasn't allowed to even pick up a toy for 6 weeks...no grocery bags, not pick up my daughter (who thankfully was 3 so I could have her walk but it was hard)
Now when I feel those familiar twinges I ease up on lifting and lay on a heating pad when I can.
Good luck
