Hello, Thank you for your contact to healthcare magic. I understand your health concern, if I am your doctor I suggest you that this is the sign of peripheral cyanosis. The reason for such a condition may be some heart disease, or some kind of poisoning, or some large blood vessel disease. But exact diagnosis and so management can only be possible after your confirm diagnosis. In my advice you should visit to the nearby doctor for general check up and diagnosis. I will be happy to answer all your future concern. Thank you, Dr Arun Tank Infectious disease specialist. Wish you a best health at health care magic.
