After pulling my back out, I was put on
cyclobenzaprine. After 1 week of taking this medication, I woke one morning
with numbness and tingling from the mouth down. My primary care physician felt that cyclo could not have caused this sensation; however, I stopped taking cyclo due to my inner voice. After 46 hours the tingling and numbess was gone, i.e... cyclobenzaprines half life is between 18- 48 hrs. After researching this topic, I found MANY individuals with the same symptoms.
