cervical dystonia
"I received injections in neck, shoulders and calf.  Serious side effects of feeling like I have been poisoned for 1-2 weeks after the injections.  I still have incredible pain and muscle weakness.  My calf muscle still cramped and knotted.  Difficulty swallowing at times.  I really don't know if it worked at all for me.  It's been a year and I still am wondering what benefits I am receiving."
