I had issues when I was BF and discovered it was the way I was holding DS that was causing the wrist pain - once I became aware of the issue and changes it, it went away!
I had the same thing, and as MummyNaomi said, it was mainly caused by the way I would hold DD when BF. I saw a physio, and had some ultrasound treatment on it, as well as using nurofen jel, and also was given some wrist splints, which I wore infrequently as they were just impractical with a baby! Until you can get to see someone, definately try some nurofen jel or similar, and maybe try to focus on what things aggrevate it, so that you can adapt things.
