Question: Bluish Knuckles

 LCarrat123 - Sun Dec 30, 2007 9:20 pm

Can anyone tell me what possible causes might be for my blue knuckles? I have not been exposed to the cold and I am guessing it may be due to low blood flow. My hands are not cold. Any ideas?

User avatar Hi LCarrat123,

This may be due to some changes in blood vessel contriction causing some back up of blood in the area. If this is only intermittent it is probably nothing to worry about. If it persists I would recommend that you see your doctor for an evaluation.

Best wishes.
