I know anyone who reads this will think I've lost my mind, but in addition to my neck pain, extreme upper arm pain when I move my arm up or out, now I can't sit comfortably because my rib cage area hurts. It's all on my left side. Can the cervical area cause pain n the rib area? I'm 15 weeks post op c4/5. I have more Mri's and more nerve test scheduled or Wednesday. Anybody have any ideas! I about to lose it! Please!
