I have the leg cramps at night too, plus the restless moving of my legs a lot. Sometimes it's so bad that, I have to go to bed, & then it will ease up some. I thought it was restless leg syndrome, but my doctor has never really addressed my concerns about it. And, I know next to nothing about lupus, so am learning as I go. I had a bad thyroid, that was removed in Jan of '11, & the side effects of hypothyroidism, & of lupus are VERY similar. (Hair loss, weight gain, etc)
