Tennis elbow, medically known as lateral epicondylitis, is a common condition that causes pain and inflammation around the outer part of the elbow. Despite its name, it isn’t limited to tennis players—it can affect anyone who repeatedly uses the forearm muscles and tendons, especially with activities involving gripping, lifting, or twisting motions. The pain typically starts as a mild discomfort but can worsen over time, making it difficult to perform everyday tasks like shaking hands, turning a doorknob, or holding objects.
The underlying issue in tennis elbow is the overuse and small tears of the tendons that attach the forearm muscles to the bony bump on the outside of the elbow. This repetitive strain leads to inflammation and pain. It usually develops gradually and is often linked to repetitive motions in sports, work, or hobbies. While the pain is localized to the elbow, it can sometimes radiate down the forearm. Understanding the cause and avoiding aggravating activities are important steps in managing the condition.
