Overview

What Is Tennis Elbow?

Tennis elbow is irritation or degeneration of the tendons that attach the forearm muscles to the bony outer part of the elbow. It is also called lateral epicondylitis, although tendon wear and degeneration are often more important than active inflammation. Repeated gripping, lifting, racquet sports, manual work, and computer use can trigger it. Despite its name, tennis elbow can affect people who have never played tennis.

Symptoms

Tennis Elbow Symptoms

Tennis elbow symptoms usually develop gradually rather than after one clear injury. Pain is commonly felt on the outside of the elbow and may worsen with gripping, lifting, or moving the wrist and forearm. The discomfort can make everyday activities harder, even when the arm looks normal.

  • Pain over the outer elbow is a common early symptom.
  • The outer elbow may feel tender when pressed.
  • Gripping objects can increase elbow pain.
  • Lifting or twisting the forearm may cause pain.
  • Grip strength may become reduced in the affected hand.
  • An aching feeling may spread into the forearm.
  • Everyday tasks such as opening jars, carrying items, or using tools may become difficult.

Causes

What Causes Tennis Elbow?

Tennis elbow develops when repeated gripping, lifting, wrist extension, or forearm rotation overloads the tendon attachment at the outer elbow. Over time, this stress can cause small tissue injuries and changes in the tendon, leading to pain and reduced tolerance for activity. The problem is usually related to repeated loading rather than a single traumatic injury, although a sudden increase in activity can bring symptoms to the surface.

  • Racquet sports can repeatedly load the wrist and forearm tendons.
  • Manual work involving tools, gripping, or repetitive arm movements can trigger symptoms.
  • Keyboard or mouse use may contribute when the wrist and forearm remain in the same position for long periods.
  • Cooking tasks such as chopping, stirring, or lifting pans can repeatedly strain the elbow.
  • Gardening can involve gripping tools and twisting the forearm.
  • Repeated lifting at work, home, or during exercise can overload the tendon.

Risk Factors

Tennis Elbow Risk Factors

Can be changed

Modifiable factors
Repeated gripping, abrupt increases in activity, poorly fitting equipment, and inefficient movement technique can increase tendon strain.

Less changeable

Other factors
Middle age, occupations involving repetitive arm use, and previous tendon or elbow problems can make tennis elbow more likely.

Complications

Tennis Elbow Complications

  • Persistent pain can interfere with work, exercise, and household activities.
  • Ongoing tendon symptoms may reduce grip strength.
  • People may need to limit activities that load the affected arm.
  • Elbow discomfort can disrupt sleep when the arm is positioned or used during the night.
  • Delayed improvement can lead to a prolonged recovery.
  • A tendon tear or another diagnosis is uncommon, but persistent or changing symptoms may require reassessment.

Diagnosis

How Tennis Elbow Is Diagnosed

A clinician will ask when the symptoms began, which activities make them worse, where the pain is located, and how it affects daily function. During the examination, they may check for tenderness, grip strength, wrist and forearm movement, elbow motion, and pain or weakness against resistance. This assessment also helps distinguish tennis elbow from other causes of elbow pain.

When Are Tests Needed?

Diagnosis is often clinical, so imaging is not routinely needed when the symptoms and examination are typical. An X-ray may help assess bones or arthritis, while ultrasound or MRI may be considered for persistent symptoms or to evaluate another tendon, joint, nerve, or structural problem. Your clinician will choose tests based on the findings and your response to initial care.

Treatment & Management

Tennis Elbow Treatment and Management

First-Line Care and Rehabilitation

  • Physiotherapy can guide pain management, movement changes, and a gradual return to activity.
  • Gentle stretching may help maintain wrist and forearm flexibility when recommended by a clinician.
  • Progressive wrist and forearm strengthening can gradually improve tendon capacity.
  • Correcting sports, work, or lifting technique can reduce repeated tendon strain.
  • A brace or counterforce strap may help some people during activities when fitted and used appropriately.

Options for Persistent Symptoms

When symptoms continue despite rehabilitation, a clinician may discuss injections or other procedures if they are appropriate for the individual situation. Surgery is uncommon and is generally considered only when pain and loss of function persist after a prolonged course of nonsurgical treatment. Tennis elbow treatment should be individualized, and improvement may take weeks to months rather than occurring immediately.

Prevention

How to Help Prevent Tennis Elbow

  • Increase sports, work, and exercise activity gradually rather than making sudden increases.
  • Use proper technique and equipment that fits your activity and body.
  • Take regular breaks during tasks that involve gripping or repeated arm movements.
  • Vary repetitive tasks when possible to reduce continuous loading of the same tendons.
  • Strengthen the forearm gradually with exercises suited to your ability and recovery stage.
  • Respond early to recurring pain by reducing the provoking activity and seeking advice if it persists.

Outlook and Prognosis

Tennis Elbow Outlook and Prognosis

Many people improve without surgery, but tennis elbow can persist for several months, especially when the activity that provokes it continues. Recovery is often gradual because the tendon needs time to tolerate normal loads again. A tailored rehabilitation plan can help restore function while avoiding repeated flare-ups.

When Should You See a Doctor

When Should You See a Doctor for Tennis Elbow?

Schedule an evaluation

Persistent or limiting symptoms need assessment

Arrange an evaluation if elbow pain lasts more than a few weeks, interferes with work or sleep, causes meaningful weakness, or does not improve with initial self-care. A clinician can check for tennis elbow and other causes of pain in the elbow or forearm.

  • Seek urgent assessment for major swelling or a visible deformity.
  • Seek urgent assessment if you cannot move the arm normally.
  • Numbness or loss of sensation in the arm or hand needs prompt medical evaluation.
  • Sudden severe pain after an injury should be assessed promptly.
  • Fever with a hot, red, or swollen joint requires urgent medical attention.
  • Rapidly worsening weakness needs prompt evaluation.
