Check this out - last night I was training, pulled quite hard on a small 2 finger pocket and felt pain through my wrist and up my forearm. I shook it out and it didn't feel bad at all, so I carried on climbing (with no pain, not even on small crimps/anything).
When I got home, it was a bit sore, but I had a bath and it went away.
However, when I woke up this morning it hurt like bejeesus, and still does. And yet, if I crimp, it doesn't.
WTF is it on about?
