, ugh. I'm sorry. I think people sometimes forget how painful and disruptive muscle cramping can truly be. I hope some of the tips from the link I shared work for you. I had forgotten about tonic water (quinine) and one member suggested Flexeril, which is a muscle rub that can be purchased over the counter. Also, arnica cream (it's kind of like muscle rub without the burning/icy sensation) might be worth a shot.
I'm sorry. I know being in pain stinks.
