Great write-up. Good decison to turn around when injured, you didn't miss much.
My doctor was marvellous when I explained I was often miles away from roads, and gave me a prescription for 100!! co-codamol tablets each with 30mg of codine for emergency pain control.
I also always carry Voltarol (non-steroidal anti inflamatory cream) but if you don't have it you can make up something similar by finely crushing ibuprufen and mixing with a face cream.
I also got caught in a sandstorm and the paint on the right fork has been worn off.
