Causes

Tendons connect muscles to bone. Repetitive or stressful movements of the muscles causes strain and pain at the tendon. The forearm muscles are active when a person grips something, such as a tennis racquet. Doing this repeatedly can cause pain at the tendon. Other things that may cause this problem are:
  • Hitting a tennis ball incorrectly
  • Using the wrong size tennis racquet or the wrong tension of racquet strings
  • Gripping or swinging a golf club the wrong way
  • Doing certain arm motions too much, such as:
    • Tennis strokes
    • Golf swings
    • Painting
    • Raking
    • Pitching
    • Rowing
    • Using a hammer or screwdriver

Risk Factors

This problem is more common in older adults. Other things that may raise the risk are:
  • Playing tennis or golf
  • Jobs that use repetitive wrist extension and gripping with a closed fist
  • Muscle imbalance
  • Lack of flexibility

Symptoms

Symptoms happen slowly over time and may be:
  • Pain and tenderness on the outside of the elbow
  • Pain that may go down the forearm
  • Tight forearm muscles
  • Stiffness or trouble moving the elbow or wrist
  • Not being able to fully extend the elbow
Pain may be worse when:
  • Shaking hands
  • Turning doorknobs
  • Picking up objects with the palm down
  • Hitting a backhand in tennis
  • Swinging a golf club
  • Pressing on the outside of the elbow

Diagnosis

The doctor will ask about your symptoms and health history. You may also be asked about your recent physical activity. A physical exam will be done. It will focus on the elbow.

Treatment

The goal of treatment is to ease pain and help with healing. Choices are:
  • Supportive care, such as cold compresses and avoiding activities that cause pain
  • Physical therapy to help with strength, flexibility, and range of motion
  • Wearing a forearm brace to limit movement during healing
  • Medicines, such as:
    • Over the counter pain relievers
    • Corticosteroid injections to ease pain and swelling

Prevention

To lower the risk of this problem:
  • Slowly increase the intensity and duration of activity
  • Use the right techniques and equipment for sports and activities
  • Exercise regularly to keep arm muscles strong
