Hi Photophil, this sounds like joint inflammation rather than an accute injury like popping a pulley.
Place you hands in ice water for 30mins, the cold should be painful at first then eventually your body will flush the hands with lots of blood.
Do this twice a day for three days followed by icing as and when you need it. Stay off the crimps, look to trying to open hand/drag on small holds as a replacement. Pain killer/anti-inflammatory gels such as Voltarol can also help, but be mindful that they may lead you to return when your body is not ready.
Also do not neglect your shoulders, a raised shoulder blade round your ear when pulling on holds is going to cause you to raise your wrist which will lead you to switching to a crimp to keep purchase. Keep the shoulder blades back and down will let your big back muscles do the hard work.
