An overuse injury can occur when you take on too much physical activity too quickly.
1 Examples of an acute injury include sprains, strains, and contusions.  Overuse injuries occur gradually over time, when an athletic or other activity is repeated so often, areas of the body do not have enough time to heal between occurrences. Tendinitis and bursitis are common soft-tissue overuse injuries.
