A broken nose and face bruises.
I also have had a whole on one side of my abs and it hurt a lot more than the broken nose. I didn't want to make the surgeon who did the stitches nervous by making pictures of the wound. Anyway, he did a lousy job and after 2 weeks when we had to remove the stitches, the wound was not healed but infected and another surgeon had to clean it again (it hurt!). The whole recovery took me about a month and I was not able to ride a bike during this period. Not to mention the first two weeks were awfully painful. The whole was punched by my brake lever and it was about 2 inches deep. I was lucky that I didn't have any internal organs damaged.
