I don't quite know how to explain it. When I lie down to go to sleep it's as if my calves just can't relax. It's not like they're cramping or anything, it's just as if I can't find a comfortable position, like whenever I have them still it doesn't feel right. I move them about, change position, I've even just come downstairs and am lying on the floor with my legs up on the couch and it's the same. Has anyone else had this?!! It's so hard to describe, not painful or anything, but as if I need to move them about, or something. The thing is, I'm REALLY tired!! And I could do with a good night's sleep!
