I tried Skelaxin with little relief. Flexeril like WB said made me way too sleepy. I'm now taking Zanaflex which is a anti-spasmatic but it is short lived so doesn't really help either. Haven't really found anything yet that helps the muscle spasms other than Neurontin that helps the ones in the neck for some reason.
Good Luck with your search for the perfect med. It takes alot of trial and error to find the one that works for you. I don't think there is anything that will take all the pain away completely but can get it to a controllable level to function.
