Sorry I didn't know how else to describe it. Yesterday my legs (really my thighs) started feeling weak and wobbly, as if I'd just hiked up and down a mountain. A few hours later it became this ache with the weakness whenever I stood up and it would get so bad that I couldn't walk and and needed support to stand in one place. Once I'm sitting/lying down it eventually stops.

This doesn't sound like what I've read about leg cramps so I was wondering if anyone had any clue what it was?
