I have alot of pain in my left upper arm, shoulder into my neck, back & chest. At times it causes headaches and goes up my head. This has been going on for more than 8 months now. I have had an xray on my shoulder and an MRI of my neck & shoulder. I did 2 weeks of therapy also. The only thing they could see was a little bit of arthritis and bursitis in my shoulder. I have an order for a ct scan of my neck & chest. Any ideas. This pain gets very bad at times. It really seems too severe for what they have told me they have found so far. The doctors don't think I should be in this much pain for what they have found either. Thanks
