Breaks and SprainsJoint dislocations and broken bones are painful and may have long-term consequences if not handled in a timely fashion. Treat all serious arm and leg injuries as broken bones (even if you think they're dislocated). An easy reminder for almost all arm and leg injuries is the RICE treatment: Rest, Ice, Compress, Elevate.
Cuts and BleedingThe game is getting serious when the blood starts flowing. Wash all wounds with soap and water - it's the best disinfectant. Deep cuts, where you can see the bumpy fat tissue underneath, will probably need stitches. Otherwise, if you can pull the cut closed easily, try using butterfly closures.
Cuts on active areas like elbows and knees will probably need something stronger than butterfly closures.
