“Tennis elbow” or lateral epicondylitis is caused by overuse, strain, or injury on the tendon that attaches to the bone on the outside of the elbow. This tendon is attached to the muscle that bends the hand backwards from the wrist. This results in tears in the tendon, causing inflammation and pain.
Tennis elbow can be caused by any repetitive movements that involve bending the wrist in a turning or backwards motion (e.g., tennis, painting, hammering, using a screwdriver).
Your physiotherapist can help prevent these types of injuries by correcting poor technique, strengthening weaker muscles and stretching.
