I guess it all depends on what is causing the muscle spasms. I get terrible muscle spasms, just about every where, in my neck, my hands , my feet, the inside of my thighs, back of my thighs and calves, heck just about everywhere, my Doc prescribed Baclofen, I was started of at 5mg every 8 hours, and increased it up to my current dosage of 25mg every 8 hours, which seems to work pretty good, oh I still get them every now and then but not like I did before! Baclofen really has been a Godsend for me I nolonger get those horrible long lasting muscle spasms that would cause my muscle to knot up into a tight ball and not release, they would hurt so bad! I also found that since I have been on Baclofen that I don't need as much Percocet for break through pain. My pain Doc said that allot of patients that are on Baclofen also report that it helps relieve pain. You might want to ask your Doctor about it.
Good Luck to You
