Sounds rather like poor circulation. Lack of oxygen in the feet (or elsewhere) could cause cyanosis, and that makes the skin look blue. When the blood supply has been cut off from, say, the feet, and then returns, tingling is sometimes felt.
feet turn blue when they are really cold and when there is barely any oxygen getting to them
I would recommend that you see your doctor right away.
When legs and feet turn blue, it is an indicator that circulation has been cut off. If blood flow is not restored, tissue will rapidly die and can result in amputation.
When toes turn blue, the cause is usually bad circulation. The body isn't getting oxygenated blood to the extremities.
not just the hands and feet but the whole body
Fingers and feet turn blue in the elderly because these individuals have poor circulation. The blue color is the effect of the area becoming cold.
When your feet turn purple and blue, it can be a sign of circulation problems or Raynaud's disease, a disorder involving the blood vessels. With this condition, there is a narrowing of blood vessels in response to cold temperatures or stress.
you have the flu
because there blue
I think it has something to do with Raynaud's disease. That means that when it's cold, your veins narrow, causing the flow of blood to your hands or feet to decrease or even stop. Result: your fingers/toes turn white or even blue. Normally, this stops after a few minutes or hours and then they turn pink again. During this process, your fingers can tingle or hurt. The best thing to do is keep yourself warm and avoid smoking, because that could also trigger it. I'm not one hundred percent sure whether it's right, but that's what I read about it.
Dermeculitus is when the hands and feet turn a sickly green colour and the only way to cure it is to have unusually painful injections by needle or stick your hands and feet in lizard pee!

Your feet turn blue-purple when they do not get enough blood flow or when they are lacking circulation or some times they are cold the best thing to do is rub them or run them under warm water.
Unfortunately the bones are built differently and you do not have as complex nerve connections to your feet so no
Dermatemeculitus is a disease when your hands and feet turn green. The only ways to get rid of it is a series of painful injections or dipping hands and feet in cifolic acid found in the urn of most lizards....
