hello, I have had soreness in my arm, tingling in my fingers and severe pain in the back of my shoulder. I have been to neurologist and no nerve damage, but my MRI shows bone spurs, arthritis and degenerative tissue in my neck. I go to the pain clinic soon and would like to know my best options for treatment. I am in good shape, exercise and weigh 110 at 5 2 . I have been to physical therapy and they said I need to go to the pain clinic and have a cortisone injection. Should I get another opinion?
