If you need to use one crutch or cane make sure to use it on the opposite side of your painful or injured leg. The purpose of a crutch is to help you move normally. When used on the opposite side, a crutch will unload the painful leg and reduce limping. If used on the same side, it will cause a limp (Have you ever seen House M.D.) This creates bad habits that’ll need to be addressed later.
