Skelaxin is pretty wimpy. I used it and wondered if there was really any med in it?

Flexeril helps for a lot of muscle stuff (even skeletal muscle) - I take 10-20 mgs. Caution though, it may knock you out and you might want to try that at bedtime.

Zanaflex - I take 4 mgs, and I don't know if it makes me sleepy because I have only taken it at bedtime. But it does seem to hlp for most of the next day.

If muscle relaxers do not work though it could be other things.

Already mentioned to get heart and gall bladder checked, and you don't have the gall bladder. Also check lungs and look into stomach problems - could be ulcer even if you don't feel pain the way you'd think you would.

People with ms often feel pain in weird ways.

Good luck with this, hope you get some relief.
