I am so sorry about your accident. I hope it is nothing serious.

About 4 or 5 years ago I was riding in a bike lane and an old lady in a huge Caddy, who wanted to turn right into a bank parking lot as I was approaching the entrance, moved right into the bike lane so that other cars could pass her then finally made the turn. In doing this, I had to brake very very hard. My tire was up against her bumper when I finally stopped. I was so Hot , I slammed my fist down on her trunk. She looked up in her mirror, shocked but did nothing to apoligize. To this day, I hate it when people use the bike lane as a turn or passing lane.

My opinion about the wrist, consult a physical therapist and see what you need to do to condition it. They may suggest to exercise it by sitting on the floor at a hard surface (a chair or an end table) in front of you. Place your arm on the surface with your wrists just over the far end of the table at the ledge. Place a 5 lb. weight in your hand and have your hand lift it up and down slowly.

Hope this helps.
