I fractured 7 vertebrate recently, then a few days ago, I sprained my ankle. I am on pain meds as well as 4 mg Tizanidine 4x/day. When I first fractured my vertebrate a few months ago they gave me flexoril (10mg's). I am not completely sure if I notice a difference between the two (been on Tizanidine for 1 day). But between the two, which one is more potent, and/or works best to relax my aching muscles both in my back and now in my ankle. Thank you
