as you know i have had acdf in june of 09. well the solid burning in neck, and upper back is progressing again, just like before surgery. as well as new pain from throracic i think, that wraps around my upper chest. i do suffer from RSD . my neck also has severe pain when turning certain ways, i try not to at all. i have to sleep on right side at nite. i cannot even lay on my back for very long, before having to turn because of pressure on my neck, and back, muscle spasms, shooting pains. i realize rsd is a result of some of this, but the neck definately does feel like it did before i had the surgery. i had herniated disc, and did not even know it. the burning pain is always there just like before. this is before i even had any of my surgeries, and was walking around like that, and could not even look up, like now also. i am afraid of what it could be again. does anyone have any input? or suggestions? i would appreciate it , thanks Leo ~X( :?
