You really are lucky it wasnt worse. I gotta tell you though.....I saw my buddy taxi his plane(throttle linkage came loose) between his legs,but the prop put a small gash in his leg. Werent sure if it should have stitches either,but they did stitch it. BUT,the problem he had wasnt the cut or even the stitches. It was the terrible infection he got even though he put stuff on it etc. You will likely need antibiotics prescribed to you. There must be something about airplane fuel and dirty props that really makes it hard to keep infection under control. Ask your doctor for antibiotics.
