About three years ago, I got up in the middle of the night to go to the bathroom and I immediately crumpled to the floor. I tried to stand up, but just fell right down again. Finally I managed to pull myself up on the bed. I thought my leg must be numb, so I massaged it. But it wasn't really numb, just weak. I couldn't get out of bed for about four more hours and then I had to hold on to things to keep from falling down. That lasted for about three days and since then my thigh has been weak. It seems to get worse when I am very tired. Lately I've been having trouble walking up the stairs, I kind of have to swing my leg up. I cannot get up from kneeling down without something to pull me up. When my leg is weak, I am having to concentrate when I wak to make sure I don't stumble.
Anyone have any idea what it might be? I haven't fallen again, so it makes me think it can't be that big of deal, but it is annoying. My thigh kind of aches most of the time. My foot on that leg also twitches, mainly at night. I don't know if it has anything to do with the weakness.
