I was awakened from a dead sleep at 6am with the the absolute worst "charlie horse" in my right calf ever!! My leg got numb from my toes to mid-thigh. Rubbing it didn't help. It just happened...I didn't even stretch (which often brings them on). I thought I was going to die.
I discovered on-line that this is yet another WONDERFUL occurance that goes along w/being PG. They happen more during 2nd and 3rd trimester as weight increases - oh joy!!
I've had a few in the past month, but none this bad. I was nearly in tears, it was that bad.
