I am a 27 year old female who was diagnosed with sciatica 6 years ago. 2 weeks ago my lower back went into a spasm that ran down my left leg into my foot, I can't feel my big toe and the top of my foot. I was given a Valium and 2 other pain meds in shots. The E.R doc said to take 10 mg flexiril for pain 3 times a day. The day after my incident I was cometely drugged up. Slept all day and night. Not sure if its from the hospital drugs or the flexiril I took the day after. Does the flexiril help with sciatica as well as muscle spasms!!!
