carolyn, your electrolytes could be out of balance. low potasium or magnesium can cause spams or cramps. all the sweating that you do could be the cause of this.

my mother went through years of this problem. hospitalized many times until it was dx'ed and taken care of. she had the same sweating problem. it can be serious. she almost died.

not trying to scare you, but your sweat isn't just plain water.

a blood test can check for this. but they need to really look at the results. if the levels are even a tad on a low side, they still need to be fixed. most dr's will just let you slide because you aren't in a danger zone.
