I had horrendous leg cramps my leg would start to turn inward, all the muscles would cramp and it felt like all my joints were going to dislocate themselves. I found having a warm bath while pressing ur toes back on the end of the bath and having Dad2b give me a really rough painful massage was the only thing that stopped them, then i slept with a hot water bottle and a heatpack on my leg to keep the heat going and the leg warm. They were so bad I was almost screaming and was bauling my eyes out. Make sure you have someone to help you though if you have a bath I couldnt have got out otherwise
