I am having severe muscle spasms in my lats. Mostly on left side, but occasionally on both sides. i had cervical fusion 2 years ago and still have severe neck issues, but are these spasms related?? When the spasm hits, i am literally propelled forward and i make funny grunting noises (cuss sometimes). the pain is so strong even with new meds doctor gave me (Amrix). this is horrible...HELP, they wont stop.
