I am having a nightmare with my legs. In the evening I get really restless legs amd changing position in bed is almost scary as the sightest tensing of legs brings on cramp and when in bed I spend most of the night on the verge of sleep as I keep feeling cramp coming on in my calfs. I normally get a bit of cramp when weather warms up and add more salt to my diet as well as drink more water but can not add salt now. Have had cramp for a few nights in a row and bought a heat pad to put under legs but am too hot to leave it on, need to turn it on when I feel the cramp coming but it means I am getting about 2 hours sleep a night. Any suggestions please as I am now in tears of fustration at night with lack of sleep and have enough on my plate to stress about without this.????
