This has happened off and on, but this time it is lasting longer. My legs and feet fall asleep from the knees down. I guess it is because I need to get my bs down. I have walked 20 min. per day on the treadmill the past 4 days and can only sit a short time, then have to pace to try & walk it off. Watched every bite I took today and will continue to do that. Am hoping once my bs is in line, this will stop, it's scary.
