Cervical MRI shows a pinched nerve in my neck which has been causing severe shoulder pain which than results in muscle spasms from my shoulder blade spine area around to under collarbone, and down to elbow. Worse pain than when I had pinched nerve in lower lumbar area which was fixed with multiple injections. So far Ive had 4 trigger point injections in shoulder joint. For my back I was prescribed Soma than Robaxin along with 5mg of Oxycodone. Would this be a good choice for the shoulder pain? I don't like taking something that I have not taken before, and I had good results with the Soma/Robaxin and Oxycodone, If not I would appreciate recommendations on meds. Thanks to anyone who tries to provide me with assistance.
