I ruptured my slime bag.....
I am at the beach taking photos, or rather clambering over rocks by the sea. I slip on a particularly slippery rock and my feet shoot out from under me. Most of me, and the camera, hit the sand. My arm, including my elbow hit a rock. It hurts quite a bit but everything works so I head home to change my wet trousers. When I get there I happen to look in the kitchen mirror and see this...
Friend of my told me she suffered the same injury while in Germany. The Doctor didn't speak English and the best translation they could come up with was that she had ruptured her slime bag.
