Sports injuries can be broadly classified into two types: acute and chronic. Acute injuries are caused by a single traumatic event, such as a fall or collision, and typically result in immediate pain and swelling. Chronic injuries, on the other hand, develop over time and are usually the result of repetitive motions. Common examples include tennis elbow and runner’s knee. Both acute and chronic injuries can be extremely painful and often require professional medical treatment. If you suspect that you have suffered a sports injury, it is important to see a doctor as soon as possible for an accurate diagnosis and appropriate treatment plan.
