Tennis Elbow

Tennis elbow is one of several overuse injuries that can affect the elbow. The tendons that join the forearm muscles on the outside of the elbow become inflamed and damaged, causing microscopic tears to form in the tendon. This leads to pain and tenderness on the outside of the elbow.


  • Pain that radiates from the outside of the elbow into the forearm and wrist
  • Pain when extending the wrist
  • Pain with gripping and twisting
  • Forearm weakness
  • Pain is gradual; worsens over weeks or months
  • A painful grip during certain activities, such as shaking hands or turning a doorknob
  • An inability to hold certain objects, such as a coffee cup

Common causes:

  • Overuse injury: repeated contraction of the forearm muscles that are used to straighten and extend the hand and wrist
  • Work or recreational activities that require repetitive and vigorous use of the forearm muscles to grip and/or twist

Risk Factor:

  • Age - most common in adults ages 30 to 50, but the condition can affect anyone who repetitively stresses the wrists
  • Overuse - anyone who uses repetitive gripping and twisting movements for at least two hours a day is at greater risk
  • Smoking - increases the risk of developing tendonitis
  • Muscular imbalances
  • Incorrect ergonomics
  • Rounded posture
