Climber's elbow, also known as medial epicondylitis or golfer's elbow, is a common overuse injury among climbers. It refers to the inflammation or irritation of the tendons on the inner side of the elbow, near the bony bump called the medial epicondyle. It can result from repetitive stress or strain on the muscles and tendons that control wrist and finger flexion. Symptoms of climber's elbow may include pain and tenderness on the inner side of the elbow, weakness in grip strength, and difficulty in fully bending or straightening the arm. Rest, ice, stretching, and strengthening exercises are typically recommended for recovery, but it's always a good idea to consult with a healthcare professional for a proper diagnosis and treatment plan.
