Hi, my fiance told me that 30 years ago when he was a younger man, people in different places told him a secret for getting a better blood flow out to the extremities. For fingers/hands, just send your arms out and rotate your both hands in small circles as fast as you can. When you feel tingling in your fingers, the blood has increased in that area. For your feet and legs just hold on tight to the back of a kitchen chair while you rotate your feet as fast as you can. I also wonder if doing the bicycle exercises while laying down on your bed, and then rotating your feet in circles while in the same position will help.
