Many things: Acute or sudden blue painful spots can be due to bruising. They can come from systemic issues ( like liver, etc), hemaniomas and other things both "bad and not so bad". I would get a further evaluation with more testing . I woul imagine that the fact they have been there for a long time suggests the probably represent nothing serious... Not i would still get them checked out.
