What is a common overuse injury that can result in chronic pain?

Tendonitis is a common overuse injury characterized by inflammation of a tendon, typically resulting from repetitive movements or prolonged strain on the affected area. This condition often manifests as chronic pain, often experienced during movement or activity, and can significantly hinder a person's ability to perform in martial arts or any other physical activity.

The repetitive nature of specific movements in martial arts, such as striking, blocking, or grappling, can place excessive stress on tendons, leading to microtears and inflammation. Over time, if the stress continues without adequate rest and recovery, tendonitis can develop, causing persistent pain and stiffness.

Conversely, fractures, concussions, and dislocations tend to be acute injuries. Fractures are breaks in bone caused by sudden trauma; concussions result from impact to the head, leading to brain injury; and dislocations involve the displacement of bones at a joint, all of which typically result from specific incidents rather than ongoing wear and tear.
