I understand now and sympathize with the need to improve blood circulation. Sitting on the toilet my left foot was completely without feeling. The nail color of my big toe was darker; nearer to a faded blue.
Tried and failed to curl my toes or move my foot. It felt like a mass of uncontrollable flesh. I was worried what this meant and that it could lead to something problematic. My foot needed blood circulation.
Leaning on the right leg I pretended to ride a bicycle with the other. The tingle sensation came through to the foot and my toes moved when I willed them to move.
After the tingle came the pain. The pain that stops you from moving. You try to move and it hurts. I just didn’t move and waiting for the feeling to go away.
