Suggest Treatment For Shoulder Pain,tingling Sensation In Head And Legs

hello I am age 37. I have neck and left shoulder pain for 2 years. Had MRIS they showed mild degenitive changes such as bulding disk, arithis. Did PT did not help. Had TMJ surgery of the left joint that did not help. After I did trigger point injections something happened. I woke up the next day and my whole left arm was swollen. Afterwards my neck mucles and shoulder mucles got really weak. Things are getting progessiviely worse. Its hard for me to walk. Weakness of muscles esp in the upper area neck shoulders arms. I have had Ct s MRI s, Nerve conduction studies. My neck will just burn and burn. I have tingling senastions in my head down my legs. the last MRI showed I have a flexed neck????? I am not sure how or what is causing this considering the MRI a month ago did show the same thing. My joints feel dry and are cracking esp in my shoulders. Please help its been 3 months of torture and the drs are helping me but are at a loss.
