Key facts

Epicondylitis at a glance.

The essentials, in plain English - what it is, the two variants, and how it's treated in the UK today.

  • What it is

    Overuse tendinopathy of the elbow - degenerative rather than truly inflammatory, with collagen breakdown and neovascularisation at the tendon origin.

  • Two main forms

    Lateral epicondylitis (tennis elbow) at the ECRB tendon, and medial epicondylitis (golfer's elbow) at the flexor-pronator origin.

  • Who gets it

    Peak incidence 30 to 50 years - racquet-sports players, throwers, manual workers and anyone with repetitive gripping tasks.

  • Not inflammation

    Histology shows angiofibroblastic tendinosis, not tendonitis - which is why long courses of anti-inflammatories often disappoint.

  • Foundation therapy

    Eccentric and heavy-slow loading with a specialist upper-limb physiotherapist, plus activity modification and a counterforce brace.

  • When to escalate

    PRP, shockwave and, for refractory cases beyond 6 to 12 months, arthroscopic or open tendon release (Nirschl procedure).

Why this guide matters

A stepped plan, not endless painkillers.

Elbow tendinopathy is common, mostly treatable and - with the right ladder - usually controllable. The three points below shape everything else on this page.

  • Loading beats resting

    Eccentric and heavy-slow loading rebuilds tendon capacity - the best-evidenced conservative treatment for tennis and golfer's elbow.

  • Steroid is a bridge, not a plan

    Corticosteroid injections help short-term pain but worsen long-term outcomes if repeated - use them selectively.

  • Refractory cases have options

    PRP, shockwave and, ultimately, arthroscopic or open tendon release exist for cases that fail rehab beyond 6 to 12 months.

How the diagnosis is made

From first grip pain to a clear plan.

The steps a UK GP, sports physician or upper-limb surgeon will normally follow, in order - so you know what to expect and why.

  1. 01

    Assessing

    Focused elbow history

    Sport, occupation, repetitive gripping, throwing load and technique - and how symptoms behave with grip and lifting.

  2. 02

    Assessing

    Local tenderness and provocation

    Point tenderness over the lateral or medial epicondyle, plus Cozen and reverse Cozen provocation tests.

  3. 03

    Assessing

    Grip strength assessment

    Grip is nearly always reduced on the affected side - a simple, objective marker for tracking recovery.

  4. 04

    Confirming

    Rule out mimics

    Cervical radiculopathy, PIN entrapment on the lateral side and ulnar neuropathy on the medial side can all masquerade as epicondylitis.

  5. 05

    Confirming

    Ultrasound if uncertain

    US shows tendon thickening, hypoechoic change and neovascularity - and guides injections safely.

  6. 06

    Preparing

    MRI for atypical or refractory

    Reserved for cases that fail to respond, or where a tear, ligament injury or intra-articular problem is suspected.

  7. 07

    Preparing

    Specialist upper-limb opinion

    For persistent symptoms beyond three months of dedicated rehab, a shoulder and elbow surgeon should review the plan.

Typical timeline: clinical diagnosis on the day; imaging only if the picture is unclear.

Symptoms

What epicondylitis actually feels like.

Point tenderness at the epicondyle, grip weakness and pain with resisted wrist movement - and the features that mean it's time to escalate.

  • Lateral epicondyle pain

    Tennis elbow - pain over the outer point of the elbow that radiates into the forearm extensors, worse with gripping.

  • Medial epicondyle pain

    Golfer's elbow - pain over the inner elbow at the flexor-pronator origin, worse with wrist flexion and pronation.

  • Grip weakness

    Difficulty holding a mug, turning a key or shaking hands - a hallmark of both variants.

  • Pain with resisted wrist movement

    Resisted wrist extension reproduces lateral pain; resisted wrist flexion reproduces medial pain.

  • Morning stiffness

    A short-lived stiffness after waking or after periods of rest, easing once the tendon warms up.

  • Radiation down the forearm

    Pain often travels along the extensor or flexor muscle mass, sometimes as far as the wrist.

  • Occupational pattern

    Symptoms track working hours or training load - typists, tradespeople, racquet players and throwers.

  • Red flag - neurological features

    Numbness, pins and needles or hand weakness suggest nerve involvement (PIN or ulnar) and warrant urgent review.

Treatment

How epicondylitis is treated in the UK.

Loading rehab first, brace and injections next - and shockwave or surgery for tendons that refuse to settle.

  • Activity modification

    Reduce provocative gripping and loading - not full rest, but a temporary dial-down while the tendon settles.

  • Specialist physiotherapy

    Upper-limb physio with eccentric and heavy-slow loading (Alfredson and Tyler protocols) - the best-evidenced conservative therapy.

  • Counterforce brace

    An epicondylar clasp worn during aggravating tasks - offloads the tendon origin and reduces peak strain.

  • Topical and short-course NSAIDs

    Useful for symptom control in the first few weeks - not a long-term strategy for a degenerative tendon.

  • Corticosteroid injection

    Short-term relief in the first six weeks - poorer long-term outcomes than physio, so used selectively.

  • PRP or autologous blood

    Ultrasound-guided platelet-rich plasma or autologous blood injection - growing evidence for refractory tendinopathy.

  • Extracorporeal shockwave

    ESWT sessions delivered over several weeks - a non-invasive option for stubborn cases.

  • Surgical tendon release

    Open or arthroscopic debridement (Nirschl procedure) for refractory disease beyond 6 to 12 months of conservative care.

A quiet reminder

This guide is for information, not medical advice.

Your GP, sports physician or upper-limb surgeon knows your elbow and history and can tell you which parts apply to you. If in doubt, get seen.

Red flags

When elbow pain needs a closer look.

Most epicondylitis is manageable in primary care with physiotherapy. These are the situations that aren't - and where a specialist opinion is needed.

  • Ulnar nerve symptoms

    Numbness or tingling in the little and ring fingers with medial elbow pain - consider cubital tunnel syndrome and seek urgent review.

  • PIN entrapment features

    Weakness of finger extension with lateral elbow pain - the posterior interosseous nerve can be compressed near the radial tunnel.

  • Cervical radiculopathy

    Neck pain radiating down the arm with sensory change - a C6 or C7 root can mimic tennis elbow.

  • Sudden pop or bruising

    An acute distal biceps or triceps tear presents differently but is often missed - urgent orthopaedic review.

  • Locking or clicking

    Mechanical symptoms suggest an intra-articular loose body, plica or radiocapitellar chondral lesion rather than pure tendinopathy.

  • Systemic features

    Fever, joint swelling elsewhere or morning stiffness in multiple joints raises the possibility of inflammatory arthritis.

  • No response at three months

    Failure to improve with dedicated rehab is not a reason to keep waiting - it is a reason to escalate the plan.

  • Occupational disability

    When symptoms threaten the job, involve occupational health and Access to Work early to protect earning capacity.

  • Bilateral or unusual pattern

    Bilateral symptoms in a non-manual worker deserve a broader look, including inflammatory and metabolic screens.

Living with it

A treatable tendon problem, with a clear ladder.

Four things that make the biggest difference day to day - loading the tendon, fixing the aggravator, giving it time, and knowing when to step up.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits kept up for months do more than a heroic week of rehab that doesn't last.

  1. 01 Load

    Rebuild the tendon

    Eccentric and heavy-slow resistance work is uncomfortable at first but builds tendon capacity - stick with the physio programme.

  2. 02 Technique

    Fix the aggravator

    Racquet grip size, throwing mechanics, keyboard set-up or tool handles - a small change can offload the tendon.

  3. 03 Patience

    Think in months, not weeks

    Tendinopathy recovers over three to twelve months - short-cuts and repeated cortisone rarely help long-term.

  4. 04 Escalate

    Know when to move up the ladder

    If you're no better after three months of dedicated rehab, ask about PRP, shockwave or a surgical opinion.

Frequently asked

Everything we get asked about epicondylitis.

Quick answers on loading, injections, PRP, shockwave and tendon release surgery.

  • What is epicondylitis?

    It is an overuse tendinopathy of the elbow - degenerative change at the tendon origin rather than true inflammation. Lateral epicondylitis (tennis elbow) affects the ECRB tendon on the outside of the elbow; medial epicondylitis (golfer's elbow) affects the flexor-pronator origin on the inside.

  • Do I need a scan?

    Most cases are diagnosed clinically without imaging. Ultrasound is useful when the diagnosis is unclear or an injection is planned. MRI is reserved for atypical, refractory or suspected structural cases such as a tear or intra-articular problem.

  • Should I have a cortisone injection?

    Cortisone can settle severe pain in the short term but the long-term outcomes are worse than a well-run physiotherapy programme. It is used selectively, not as a first-line or repeated strategy for tendinopathy.

  • What is the role of PRP and shockwave?

    Platelet-rich plasma and extracorporeal shockwave therapy are options for refractory tendinopathy that has not responded to three to six months of loading. Evidence is strongest for PRP in lateral epicondylitis and for shockwave in chronic tendon disease more broadly.

  • When is surgery considered?

    Surgery is offered for cases that remain disabling after 6 to 12 months of dedicated conservative treatment. The Nirschl procedure debrides the degenerate tendon origin. Both open and arthroscopic techniques are used, with good outcomes in properly selected patients.

  • How long until I can return to sport or work?

    Most people return to normal activities within three to six months of starting a structured loading programme. Manual workers and racquet-sports players often need graded return, technique review and a counterforce brace for aggravating tasks.
