I am currently taking zaniflex but it is not helping. I have plate from C2-6. I have huge knots and muscle spasms chronically. My new pain Dr. Wanted to put me on Robaxin but I can t swallow easily and choke on big pills. Crushing is out of the question..,too bitter. I am also taking Nucynta 50 mg. and was told I could no longer take Flexeril with it because it can cause heart issues. What muscle relaxer is best for long term use and maybe in liquid oral form?
