Check it out: Could be serious. Blue or purple fingernails and fingers can be due to pooling of blood and is often lack of oxygen to the tissues. Can occur in fingers or toes. This can happen if cold to some people but we see as an effect of low oxygen at night, specifically with sleep either due to obstruction or other causes. Blood test (hemoglobin count) can be helpful as can a sleep study.
