My calf did that for the first time ever the other night. It does hurt like hell, let me tell you.

I'm hoping it is the last time, too.

Ew!!!!!!!!!!!!!!!!!

I've had this several times in my life. It hurts just as bad as you imagine. I think it's from not exercising enough, but that's my uneducated guess.

Either way: it's some real bullshit, I'll tell you that much. Eesh.

Get these pretty often. When I get them my toes want to point straight down, but that just makes it last longer.

What's really bad is I usually get them while Im sleeping. I'll feel it like a few seconds before it's full on pain and my leg wanting to keep my toe pointed down. Hurts more to move with it doing it. But I have to get my toes pulled up and high as they will go and hold them there until it stops.

Can take 5-10 minutes of just standing on the floor leaning forward against the wall so my toes are extended upward with my heels flat on the ground.

It usually comes on after I walk a lot, but like 2-3 days after the fact. Also not drinking enough water can sometimes cause it...and lack of vitamins or something can do it too. Think potassium is the one for muscle cramps, which I am mildly allergic to bananas and don't much care for them due as a result.

They happen enough that I know what's happening when it happens, but not enough to really track down the linking cause of it. Was horrible the first time I ever had one as a teen, felt like something was biting my leg with no idea how to stop it.
