Oh my god, i have never experience so much pain in my life. my arms feel like they're gonna fall off not to mention my chest and back i feel like they beat to death. after lying down for 2 hrs, i would wake up with so much pain that i would stay up all night rubbing my arms with icy hot for the muscle and bone pain after 19 days on this medication I have stopped it and been off of it for 2days now but the pain comes and go. How long before I feel better again???
