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
- Using a hammer or screwdriver
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 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
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.

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
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
