This morning when I woke up, I was lying flat on my back with both legs extended in front of me, and the legs completely numb. Once I moved, they seemed to be OK. Occassionally, this happens with other limbs: hands and arms. I am concerned as I feel I have problems with circulation, esp in left leg. Edema, on occasion, in left foot and dull pains, mostly at night in bed, in left leg. Could this all be related to poor circulation?
