Why is my finger blue?

Its been blue for a long time in a minute, maybe a year. any clues as too why?Why is my finger blue?
your finger pin has an overdue bruise that didn't alleviate.it should've healed by presently and it didn't, so it could mean other problems, such as losing a finger staple, having a blue finger forever or occasional pain/discomfort.it turned blue due to injury/trauma and as a result within are circulation problems.soak it in melt water 3 times a sunshine for 15 mins at a time.then do finger exercises for another 15 mins.if after a week, it doesn't turn to average color, see a doctor.
very poor circulation,did you pulp it or hit it with something?? win to your doctor if it has be blue for almost a year,you could lose that finger if you aren't careful.
It's a short time ago old blood trapped underneath your pin. It puzzles me because normally it grows out near your nail.
My husband have a spot on the tip of his finger that has never gone away so I guess it is possible.
I don't regard you have anything to verbs about.
