Hi, I am an adult with locah. It's strange but I had the same thing happen to me and it happens when I go off dex. Once during pregnancy and the other when I just felt like weening off. I'd get these cramps in my calves. I would get bad at times at night because I couldn't find a position for my legs to be comfortable. I had the urge to hit the back of my legs to create circulation or something. I read a little about restless leg syndrome, I also read that low potassium can cause leg cramps too. I'm interested in what others have to say about the their experiences, so please post. Thanks
