Tennis Elbow: Why It Lingers and What Actually Works

What is happening in the tendon

The muscles that lift your wrist and fingers attach to the bony bump on the outside of your elbow, the lateral epicondyle, via a shared tendon. The most commonly involved part is the tendon of a muscle called extensor carpi radialis brevis.

For years this was called lateral epicondylitis, implying inflammation. Studies of the tissue show that, in established cases, inflammatory cells are scarce. Instead the tendon shows disorganised collagen, increased water content and new small blood vessels — signs of a tendon that has been loaded beyond its capacity to adapt and is struggling to repair. That is why the term tendinopathy is now preferred, and why treatments that only target inflammation tend to disappoint.

Typical symptoms

Pain is usually felt on the outside of the elbow and may spread down the forearm. It is often mild at rest and sharp with specific tasks.

• Pain when gripping — shaking hands, holding a coffee mug, turning a door handle.
• Pain lifting with the palm facing down, such as picking up a kettle or a bag.
• Pain twisting, such as opening jars or using a screwdriver.
• Tenderness to touch just in front of and below the bony point on the outside of the elbow.
• Weakness of grip, sometimes dropping things.
• Morning stiffness in the forearm.

Who gets it

Tennis elbow is most common between the ages of about 35 and 55, when tendons are less able to adapt quickly to sudden increases in load. The biggest risk factor is a change: a new job, a home renovation, a new hobby, or working longer hours with a mouse. Repetitive, forceful gripping and sustained wrist extension are the classic culprits. Smoking and some medications are also associated with higher risk.

Ruling out other causes

Several conditions can mimic tennis elbow. Neck problems can refer pain into the outside of the elbow, and nerve compression in the forearm, known as radial tunnel syndrome, causes aching that is often deeper and further down the forearm. Joint problems within the elbow, such as arthritis or a loose fragment, cause clicking, locking or loss of movement. A careful assessment checks the neck and nerves as well as the tendon, which matters because a neck-driven elbow pain will not respond to treating the elbow alone.

Imaging is not usually needed to diagnose tennis elbow. Ultrasound or MRI can show tendon changes, but those changes are also found in people without pain and do not predict recovery well, so treatment is guided by the clinical picture.

What the evidence says about common treatments

The table below summarises how common treatments compare. The overall message is that approaches which build the tendon's capacity do better in the long run than those that only quieten pain.

Why steroid injections are not the first choice

Steroid injections often produce dramatic relief within days, which explains their popularity. However, high-quality trials have found that by six to twelve months, people who had an injection are more likely to still have pain and to have a recurrence than people who had physiotherapy or simply waited. The injection seems to quieten the symptoms while doing nothing to restore the tendon, and may impair repair.

That does not mean an injection is never appropriate, but it should be a considered decision with the trade-off clearly explained, not an automatic first step.

The exercise programme

Loading exercise works by stimulating the tendon cells to remodel and strengthen the tissue. The programme typically progresses through stages, guided by symptoms. Mild discomfort during exercise, up to about three out of ten, is generally acceptable as long as it settles by the next morning.

Early on, isometric exercises — holding a wrist extension against resistance without moving — can reduce pain and begin loading the tendon. The programme then moves to slow wrist extension with a light dumbbell, lifting and lowering under control, including emphasis on the lowering phase. Grip strengthening, forearm rotation work and shoulder and shoulder blade exercises follow, because a stronger shoulder takes load off the forearm during lifting.

Consistency matters more than intensity. Most programmes involve exercising most days for at least twelve weeks, progressing the weight as tolerance improves.

Changing how you use your arm

Exercise is only half of it. If the activities that caused the problem continue unchanged, the tendon is being overloaded faster than it can adapt. Small adjustments make a large difference.

• Lift with your palm facing up rather than down wherever possible.
• Use both hands for heavier lifts and keep objects close to your body.
• Use tools with larger, padded handles to reduce how tightly you need to grip.
• Adjust your mouse and keyboard so the wrist is neutral, not bent back.
• Break repetitive tasks into shorter blocks with changes of activity in between.
• Return to sport or heavy work gradually rather than all at once.

How long recovery takes

Tennis elbow is often described as self-limiting, meaning most cases eventually resolve, but the timeline can be long — commonly six to twelve months, and occasionally longer. A structured programme tends to speed the process and reduce the chance of it returning. Most people notice meaningful improvement in pain and grip within six to twelve weeks of consistent exercise.

If symptoms have not improved after a thorough programme of several months, options such as shockwave therapy or a specialist opinion can be considered. Surgery is reserved for a small minority.

Golfer's elbow: the inside version

Pain on the inside of the elbow, where the wrist and finger flexor muscles attach, is called golfer's elbow or medial elbow tendinopathy. It is less common than tennis elbow but behaves in much the same way: an overloaded tendon that hurts with gripping, carrying and wrist flexion, typically after a rise in repetitive work or sport.

The treatment principles are the same — reduce the aggravating load, then rebuild tendon capacity with progressive strengthening, this time focused on the wrist flexors and forearm rotation. One difference worth knowing is that the ulnar nerve runs very close to the inside of the elbow. Tingling into the ring and little fingers suggests the nerve is involved too, and that changes both the exercises and the advice about elbow positions, particularly sleeping with the elbow bent.

Working through it in a physical job

Many people with tennis elbow cannot simply stop working, and they do not need to. The aim is to keep the total load on the tendon within what it can currently tolerate while the exercise programme raises that ceiling. Rotating between tasks, using power tools in place of hand tools where practical, sharing the heaviest gripping work and taking short, frequent breaks all help. If your job is the main driver and adjustments are not possible, a short period of modified duties is often enough to let the programme take hold. When the problem developed at work, a WSIB claim may cover treatment.
