oh, NaeNae !!
that's rough, right when you gotta DO stuff, MS rears its ugly head.
sending you cool soothing blue waves of healing calm energy.
and prayers too, natch.
bring a little ice chest on the road, with a couple of ice-packs, sometimes that helps stop the leg cramps...
but don't leave 'em on too long, just a few minutes.
and keep your legs positioned so they won't cramp... bring extra pillows.
love and hugs, K
