In reply to mumrikken:
Yeah, you definitely need to ease off, but that doesn't mean you need to stop for long. Perhaps have a full week off, but when you come back to it your aim can be to get a lot of climbing done without much force on your fingers. Don't go for steep stuff on the bouldering wall, but you could do stuff that feels quite sustained in a top-rope.
After an injury (sounds like you have a minor one), warm up slowly. Sometimes I spend more time warming up than really trying with an injury. Then listen to your fingers. If it feels painful or wrong, let go.
