I have seen a few instances where people suffer from tremendous pain the legs, often around the region of ankle, going a bit down and stretching up to knee. This happens most prominently at the night during sleeping. Needless to say that sleep goes haywire.
What I need to know is that why does this happen at night only? That is, if there is any physical problem, it should manifest at other times also, right. But it doesn't. And in this same instance, I have seen that fingers of hands are legs of the patient, get involuntarily bent. Is this related? I can think of reduced intake of water and/or blood glucose level - but anything else?
And obviously, how and why this leg pain happens and if possible, ways to cure it.
