I had terrible pain in my right arm that felt like muscle spasms and also sharp shooting pains in my shoulder. My MRI showed degenerative disc disease and also bone spurs in the cervical spine. I took Zanaflex for the muscle spasms in the arm, Lortabs for pain, and also Arthrotec. This combination has worked well for me until a urine test showed I have kidney disease and was told to quit taking all the meds until the cause for KD was found. I go for the last (I think) test tomorrow and hope I will be able to resume the Athrotec again. By the way, I am 52 and was diagnosed with OA last spring. I had always been healthy and active until then. Now it seems like I drag myself around a lot. I also work full-time as an administrative assistant.
Good luck to you and I hope you can find something that helps quickly.
