Pain
  • Can relieve pain associated with muscle spasms.
  • Reviewed Flexerilon 8/19/2017I felt like it would relax my muscles too much thus making my body feel very weak and in more pain. I switched to tizanidine 2mg and feel much better. The doctors say that you have to use the muscle relaxer with the opiate. But also if there's pain usually there's immflamation.
