I've never been a person to wake up to horrible leg cramps, until about a month or so ago. It's happened a couple of times...totally freaked DH out 'cause he thought I was crying out with labor pains. The past couple of weeks my legs have been really tight and crampy, and the whole pregnancy they've been swollen. I can't even wear tennis shoes because socks leave such a mark on my ankles I worry about cutting off circulation. I drink a ton of water, but stretching them out helps. The shooting pain from your hip/lower back down the back of the leg is sciatica.
