Golfer elbow, also known as medial epicondylitis, is an overuse injury caused by repetitive motions that place stress on the tendons where the forearm muscles attach to the inner bump of the elbow. The condition causes pain on the inner elbow and difficulty with wrist movement. It commonly affects people over 30 years old who participate in sports like golf or tennis that involve swinging motions, or those with occupations requiring strong gripping. Conservative treatment includes rest, anti-inflammatory medications, physiotherapy, and bracing to decrease stress on the tendons.
