Tennis Elbow: Lateral Epicondylalgia

What is tennis elbow?

Tennis elbow describes pain on the outside (lateral) elbow, usually linked to overload of the wrist and finger extensor tendons where they attach near the lateral epicondyle. You do not need to play tennis to get it. Many cases relate to repeated gripping, wrist extension, tool use, lifting, or a sudden jump in training load.

Why does tennis elbow occur?

Tendons adapt when load rises gradually. However, when load spikes or stays high for too long, the tendon may become sensitive and painful. Common triggers include manual work, racquet sports, gym sessions with heavy gripping, new DIY projects, and long stretches of mouse or keyboard work.

How does tennis elbow develop?

Tennis elbow often starts as mild soreness during or after activity. Next, pain can show up earlier and last longer. Over time, the elbow may feel weak and irritable, especially with gripping and lifting. Although people often call it “inflammation”, persistent symptoms commonly behave more like tendon overload with reduced load tolerance.

Who is at risk?

Tennis elbow often affects adults in their working years, especially people who grip tools, carry loads, or repeat wrist and hand tasks. It also affects recreational athletes, parents lifting children, and office workers with sustained wrist and hand postures. Risk rises when workload increases quickly without enough recovery.

People also ask: is tennis elbow a tear?

Many people worry they have “torn something”. In most cases, tennis elbow behaves like an overloaded tendon attachment rather than a full rupture. Imaging is not always needed. Instead, a good assessment looks at pain triggers, grip strength, tendon load tests, neck screening, and how symptoms change with movement and load.

Diagnosis and assessment

A physiotherapist will assess your elbow, wrist, shoulder, and neck to confirm the source of pain and guide treatment. This matters because nerve-related pain (from the neck or radial nerve irritation) can mimic tennis elbow. If needed, imaging such as ultrasound or MRI may help rule out other causes, although clinical testing often provides enough direction.

Treatment options

1) Load management that keeps you active

Complete rest often slows progress. Instead, many people do better with temporary changes to painful tasks while keeping the arm moving. That might mean adjusting grip size, changing lifting technique, reducing tool vibration exposure, or breaking long tasks into shorter sets.

2) Progressive strengthening (the cornerstone)

Strengthening aims to rebuild tendon tolerance and reduce flare-ups. Programs often start with isometric loading (steady holds) for symptom control, then progress to slow resistance and eccentric-biased strengthening. Your plan may also include shoulder and upper back strength, because the whole chain influences elbow load.

3) Manual therapy and movement coaching

Hands-on treatment may help reduce pain and improve movement, especially when combined with a graded exercise plan. In addition, technique coaching (work tasks, sport skills, gym form) can reduce repeated tendon overload.

4) Bracing and straps

A counterforce strap or elbow support may help some people during painful tasks by reducing strain at the tendon attachment. Still, braces work best as a support tool while you rebuild strength. If a brace increases pain, causes tingling, or changes hand colour, stop and get checked.

5) Injections and other procedures

Some people consider injections when pain persists. Research varies by option and timing. For example, corticosteroid injections may help short-term pain for some people. However, exercise-based care often performs better in the medium to longer term for function and recurrence risk. A physiotherapist can help you weigh options alongside your work and sport demands.

How long does recovery take?

Recovery time varies. Many people notice meaningful improvement over 6–12 weeks with a consistent plan, while longer-standing cases often take several months. Your symptoms, tendon sensitivity, workload, sleep, and stress can all influence recovery speed. Importantly, flare-ups do not always mean damage. They often mean the tendon needs a smarter load progression.

Prevention tips

• Build grip and forearm strength gradually, not in big jumps.
• Warm up before heavy gripping tasks or sport.
• Use larger grip handles where possible (less tendon strain).
• Alternate tasks and take short breaks during repetitive work.
• Improve shoulder and upper back strength to reduce elbow load.

What to do next

If your outer elbow pain lasts more than 2–3 weeks, keeps returning, or reduces grip strength, a physiotherapist can assess the driver and set a staged plan. Early guidance may help you stay active while you rebuild tendon capacity safely.

FAQs

What are the main symptoms of tennis elbow?

Most people feel pain or tenderness on the outside of the elbow, plus pain with gripping, lifting, or wrist extension. Some people notice reduced grip strength or morning stiffness.

How do I know if it is tennis elbow or nerve pain?

Tennis elbow pain usually sits at the outer elbow and worsens with local tendon loading tests. Nerve or neck-related pain may include tingling, numbness, broader arm symptoms, or pain that changes with neck movement. A physiotherapist can screen both.

Should I rest completely?

Complete rest is not always required. Many people improve with load modification, short-term symptom control, and a gradual strengthening plan that builds tendon tolerance.

Do tennis elbow straps work?

A strap may help during painful tasks for some people. However, it does not replace strengthening. Use it as support while you rebuild capacity and adjust aggravating tasks.

When should I book an appointment?

Book an assessment if pain lasts more than a couple of weeks, grip strength drops, symptoms keep returning, or you cannot manage work or sport comfortably.
