Elbow bursitis, what it is, when to worry, and how it’s treated.

A soft swelling over the point of the elbow is often bursitis. Most cases settle with offloading and time, but around one in five are infected and need urgent care.

Key facts

Elbow bursitis at a glance.

The essentials in plain English - what it is, why it happens, and how the UK treats it today.

  • What it is

    Inflammation of the olecranon bursa, the superficial fluid sac overlying the bony point of the elbow.

  • Common names

    Also called student’s elbow, draughtsman’s elbow, plumber’s elbow or miner’s elbow.

  • Main types

    Non-septic (traumatic or chronic pressure), septic (infected), inflammatory (RA, gout, CPPD) and haemorrhagic.

  • Septic share

    Around 20 percent of cases are septic, most often driven by Staphylococcus aureus entering through a small skin break.

  • Range of motion

    Elbow bending and straightening are usually preserved, which helps separate bursitis from joint arthritis.

  • When to escalate

    Fever, spreading redness, systemic upset or immunocompromise mean urgent same-day review, not a wait-and-see plan.

Why this guide matters

One swelling, several diagnoses.

The elbow lump can be a nuisance or a genuine emergency. The three points below shape everything else on this page.

  • Rule out infection first

    About one in five cases are septic. Fever, spreading redness, a nearby skin break or immunocompromise are the features that change the plan.

  • Offloading does the heavy lifting

    For non-septic bursitis, taking pressure off the elbow with pads and habit change is more useful than any single tablet.

  • Aspiration and bursectomy have their place

    Ultrasound-guided aspiration confirms the diagnosis and helps large swellings. Bursectomy is reserved for chronic or recurrent disease.

How the diagnosis is made

From first swelling to a clear plan.

The steps a UK GP, emergency clinician or orthopaedic team will normally follow, in order.

  1. 01

    Assessing

    Focused history

    Trauma, leaning habits, occupation, medications, immunocompromise, fever and any skin break over the elbow.

  2. 02

    Assessing

    Elbow examination

    Fluctuant swelling over the point of the elbow, warmth, redness, tenderness and full range of motion assessment.

  3. 03

    Assessing

    Septic screen

    Fever, cellulitis, lymphangitis and systemic symptoms - the features that push suspicion toward infection.

  4. 04

    Confirming

    Bursal aspiration

    Ultrasound-guided aspiration by orthopaedics or emergency for Gram stain, culture, cell count and crystal analysis when infection or crystal disease is likely.

  5. 05

    Confirming

    Bloods

    FBC, CRP, urate and a rheumatology screen when history hints at gout, CPPD or inflammatory arthritis.

  6. 06

    Confirming

    X-ray of the elbow

    Reserved for trauma, chronic disease or suspected bony spur, erosion or calcification.

  7. 07

    Preparing

    Referral pathway

    Orthopaedics for septic, refractory or surgical cases. Rheumatology when an inflammatory driver is confirmed.

Typical timeline: most non-septic cases resolve within two to six weeks with offloading.

Symptoms

What elbow bursitis feels like.

A soft swelling at the point of the elbow with preserved joint motion. And the features that signal infection or a deeper problem.

  • Swelling over the point of the elbow

    A soft, egg-shaped swelling posteriorly over the olecranon - the classic sign that defines the condition.

  • Fluctuant, movable lump

    The bursa feels fluid-filled and mobile beneath the skin rather than fixed to bone.

  • Warmth and redness

    Localised heat and erythema, especially over the swelling, raise suspicion of septic or inflammatory bursitis.

  • Pain on pressure

    Discomfort when leaning on the elbow or resting it on a hard surface, sometimes with a bruised ache.

  • Preserved elbow motion

    Bending and straightening are usually near normal, which helps rule out joint arthritis or an intra-articular injury.

  • Occupational pattern

    Writers, plumbers, gardeners, tilers and students who lean on their elbows for long periods are the classic groups affected.

  • Small skin break

    A cut, graze or crack over the elbow that later swells and reddens is a common route in for septic bursitis.

  • Red flag - fever and spreading redness

    Systemic upset, cellulitis around the swelling or rapid enlargement need urgent assessment for infection.

Treatment

How elbow bursitis is treated in the UK.

Offloading, NSAIDs and time for most cases. Aspiration and antibiotics when infection is likely. Bursectomy for chronic disease that refuses to settle.

  • Pressure offloading and elbow pads

    The single most useful step - remove the friction that caused it. Padded sleeves protect the bursa while it settles.

  • NSAIDs and simple analgesia

    Short courses of oral or topical NSAIDs ease pain and inflammation in non-septic disease when there are no contraindications.

  • Ice, compression, elevation

    Standard soft-tissue care - short ice sessions, a compression sleeve and elevation reduce swelling in the first days.

  • Aspiration

    Ultrasound-guided aspiration under sterile conditions is used for diagnosis in suspected infection and for large or symptomatic swellings.

  • Steroid injection

    Selective use only, and only when infection is excluded. Carries a real risk of skin thinning, recurrence and septic transformation.

  • Antibiotics for septic bursitis

    Flucloxacillin, or clindamycin if penicillin-allergic, guided by local microbiology. Oral for 10 to 14 days after drainage, IV first if systemically unwell.

  • Treat the underlying disease

    Gout, CPPD or rheumatoid arthritis need their own long-term plan - urate-lowering therapy, colchicine or DMARDs where indicated.

  • Bursectomy

    Open or endoscopic removal of the bursa is reserved for chronic, recurrent or refractory cases that fail conservative care.

Treatment by type

Non-septic bursitis

Rest, elbow pads, activity modification, ice and compression. Oral or topical NSAIDs for pain. Ultrasound-guided aspiration with or without a cortisone injection in carefully selected chronic cases. Olecranon bursectomy for recurrent or refractory disease.

Septic bursitis

Urgent drainage with Gram stain and culture. Empirical flucloxacillin, or clindamycin for penicillin-allergic patients, guided by local microbiology. Ten to fourteen days of oral therapy after drainage, IV first and inpatient admission if systemically unwell. Incision and drainage where an abscess has formed.

Inflammatory bursitis

Treat the underlying disease. Allopurinol or febuxostat for chronic gout, colchicine for acute flares, and DMARDs for rheumatoid arthritis. CPPD (pseudogout) is managed with NSAIDs, colchicine and, if needed, joint aspiration under rheumatology guidance.

Haemorrhagic bursitis

Review anticoagulation and correct any coagulopathy. Compression, elevation and specialist orthopaedic input. Aspiration is avoided in the acute bleeding phase unless the swelling is compromising skin.

Red flags

When elbow bursitis needs urgent attention.

Most cases settle with time and offloading. These are the situations that don’t - and where a same-day opinion matters.

  • Fever and systemic upset

    Temperature, rigors, tachycardia or feeling generally unwell alongside a hot elbow swelling need same-day assessment for septic bursitis.

  • Spreading cellulitis

    Red streaks tracking up the arm or expanding redness beyond the bursa suggest cellulitis and possibly early sepsis.

  • Immunocompromise

    Diabetes, chemotherapy, biologic therapy, steroids and CKD lower the threshold to treat as septic and to admit for IV antibiotics.

  • Rapidly enlarging swelling

    Quick growth over hours to a day, especially with pain out of keeping with the surface findings, warrants urgent review.

  • Recent penetrating injury

    A puncture wound, bite or deep abrasion over the olecranon dramatically raises the chance of joint or bursal infection.

  • Anticoagulation with a large swelling

    A tense, expanding swelling on warfarin, a DOAC or antiplatelet therapy can be haemorrhagic and needs coagulation review.

  • Failure to settle after two weeks

    Non-septic bursitis that is not improving with offloading and NSAIDs deserves imaging, aspiration or a specialist opinion.

  • Recurrent bursitis

    Repeated episodes point to unresolved friction, an underlying inflammatory disease or chronic thickening that may need bursectomy.

  • Concurrent joint symptoms

    Pain deep in the elbow joint, restricted rotation or locking suggests something beyond bursitis and needs joint-level assessment.

Living with it

A treatable condition, with a clear ladder.

Four things that make the biggest difference day to day - offloading, patience, watching for infection and rebuilding gently once the swelling has gone.

A quiet reminder

Consistency beats intensity, every time.

Small, steady habits kept up for weeks do more for a bursa than a heroic weekend of rest that goes back to leaning.

  1. 01 Offload

    Keep the elbow off hard surfaces

    Elbow pads, forearm rests and a change of leaning habits do more than any tablet for chronic pressure bursitis.

  2. 02 Patience

    Give it weeks, not days

    Non-septic bursitis usually settles over two to six weeks. Reserve escalation for cases not improving or getting worse.

  3. 03 Watch

    Know the infection signs

    Increasing redness, warmth, pain, fever or feeling unwell means stop, contact a clinician and get seen the same day.

  4. 04 Rehab

    Rebuild after settling

    Once the swelling has gone, a short rehab plan restores confidence in leaning, gripping and lifting through the elbow.

Frequently asked

Everything we get asked about elbow bursitis.

Quick answers on septic vs non-septic, aspiration, antibiotics, steroid injections and surgery.

  • What is elbow bursitis?

    Elbow bursitis, also called olecranon bursitis, is inflammation of the small fluid sac that sits over the bony point of the elbow. It causes a soft, fluctuant swelling posteriorly and can be triggered by pressure, trauma, infection or an inflammatory disease such as gout or rheumatoid arthritis.

  • How do I tell septic from non-septic bursitis?

    Septic bursitis is more likely when there is fever, spreading redness, marked warmth, severe tenderness, a nearby skin break or systemic symptoms. Non-septic bursitis usually feels sore and tight but the elbow moves well and there are no systemic features. Ultrasound-guided aspiration with Gram stain and culture is the definitive test when infection is suspected.

  • Do I need antibiotics?

    Only if the bursitis is septic. Culture-guided oral flucloxacillin, or clindamycin for penicillin-allergic patients, is typical for 10 to 14 days after drainage. IV therapy and admission are reserved for people who are systemically unwell, immunocompromised or failing oral treatment. Non-septic bursitis does not need antibiotics.

  • Should the bursa be drained?

    Aspiration is used to confirm or exclude infection, to send fluid for crystal analysis, and to relieve large, symptomatic swellings. Blind aspiration can be avoided in favour of ultrasound-guided drainage under sterile conditions by orthopaedics or a specialist musculoskeletal service.

  • Are steroid injections a good idea?

    They are used selectively and only after infection has been excluded. Steroid injections into the olecranon bursa can help chronic non-septic disease but carry real risks - skin thinning, recurrence and turning a non-septic bursa septic. Most UK practice reserves them for carefully chosen cases.

  • When is surgery needed?

    Bursectomy - open or endoscopic removal of the bursa - is considered when the bursitis is chronic, recurrent or refractory to conservative care, or when there is a persistent draining sinus. It is a specialist decision, usually after months of pressure offloading, NSAIDs and, in selected cases, aspiration have failed.
