Tennis elbow or lateral epicondylitis is a type of tendinitis that is characterized by swelling of the tendons causing pain in elbow and arm. These tendons connect the muscles of lower arm to the bone. Any strain on the muscles will put too much stress on the tendons leading to tendinitis.
Characteristics of tennis elbow:
Cause: Repetitive gripping activities using the thumb and first two fingers like playing tennis, racquet ball, squash etc. OR weight lifting OR jobs/hobbies that require repetitive wrist movements like painting, typing, carpentry etc.
Symptoms: Pain and swelling in the bony knob on the outside of elbow that radiates to upper or lower arm. Pain especially occurs on lifting something, making a fist or grip, opening a door etc.
Treatment: Conservative treatment may give relief to the patient but if it fails to do so, elbow arthroscopy is performed to remove the damaged tendon and repair the remaining tendon.
