There is nothing worse for an athlete, than being forced to pause because of an injury. Out of all injures, fractures are not always the worst. While a broken bone usually heals within 3 to 6 weeks, tendon and nerve injuries cure much slower. Because injured tendons and nerves don't restrict the training with a plaster, many athletes go back to training too soon, which slows down the recovery process. One of the most dangerous injuries are nerve-injuries. For example when a nerve gets overstretched, (often happens when the shoulder is dislocated) or when a nerve separates. The concerned muscles or muscle groups often stay paralyzed for a long time (sometimes even forever). Other common sports injuries are ruptures, inflammations, deformations, joint wear outs etc.
