Baclofen
"I've had sciatica for 20 years. On and of a number of different meds but had negative effects. Had a bad fall Oct 30-2013 (i'm 65 on walker and canes) and square on my coccyx. Oh boy. Doc gave me Toradol pills--nothing, then cyclobenzaprine--bad effect, then BACLOFEN 5MG 3X DAY DOES HELP ME SLEEP AT NIGHT. ON IT NOW A MONTH."
