A couple of days ago I woke up in the middle of the night to use the toilet, still half asleep I stood up and immediately hit the floor waking up my husband. As I tried to get up I realised my left leg wasn't working. when I eventually got up I had to put all my weight on my other leg. i didn't have any pins and needles and I could still feel my leg so it wasn't numb. Now the muscles in my leg are quite sore. I've also been getting a strange jumping sensation in my head. Has anyone else experienced anything like this?
