This happened when I was 6 then again at 9 and once more at 10. One morning I couldn't walk. When I tried to out weight on my legs they would crumble. No pain, and I could feel them, but not a lot of movement if I can remember. I tried getting out of bed but I couldn't stand, I just flopped to the floor. I stayed home that day. My mother thought I was just making it up so I wouldn't have to go to school, but I wasn't. About 8 hours later I was able to stand again, kind of and slightly walk. That night I was completely back to normal. That happened again in the middle of the night a few years later and I think my legs felt like pins and needles it was really weird and scary. But by morning I was fine. Then it happened again a few more years later and that was the whole day thing.
Any suggestions on what causing my legs not being to support my body then being able to again?
