Health condition · Clinically reviewed
Lymphoedema, compression therapy and when surgery can help.
Persistent limb swelling from impaired lymphatic drainage is chronic, but rarely untreatable. A structured therapy plan controls it - and, for some, surgery goes further.

Key facts
Lymphoedema at a glance.
The essentials, in plain English - what it is, why it happens, and how it is managed in the UK today.
-
What it is
A chronic, progressive build-up of protein-rich lymph fluid in tissue caused by impaired lymphatic drainage.
-
Two main types
Primary - congenital lymphatic dysfunction - and secondary, which is far more common and usually follows cancer treatment.
-
Leading cause
Lymph node dissection plus radiotherapy, especially for breast cancer, causing arm lymphoedema.
-
Diagnostic sign
A positive Stemmer sign - inability to pinch a fold of skin at the base of the second toe or finger - is a reliable clinical marker.
-
Gold-standard care
Complete decongestive therapy - manual lymphatic drainage, multi-layer bandaging, exercise and skin care.
-
Long-term outlook
Not curable in most cases, but very manageable with lifelong maintenance compression and good skin care.
Why this guide matters
Chronic doesn't mean unmanageable.
Lymphoedema is usually lifelong, but with the right therapy most people keep it well controlled. The three points below shape everything else on this page.
-
Most cases are secondary
Cancer treatment, especially breast cancer surgery with lymph node removal and radiotherapy, is by far the commonest cause in the UK.
-
Compression is the backbone
Complete decongestive therapy followed by lifelong maintenance garments controls swelling for the great majority of patients.
-
Surgery has a real, growing role
Lymphovenous anastomosis and lymph node transfer offer meaningful improvement for carefully selected, severe or resistant cases.
How the diagnosis is made
From first swelling to a clear plan.
The steps a UK GP or specialist lymphoedema service will normally follow, in order - so you know what to expect and why.
Phase 1 · Assessing
History, exam and staging
Phase 2 · Confirming
Scans to exclude other causes
Phase 3 · Preparing
Genetics and specialist referral
- 01
Assessing
Clinical history and limb exam
A review of onset, prior surgery, radiotherapy, infections or family history, plus a check for the Stemmer sign.
- 02
Assessing
Staging the severity
The International Society of Lymphology stages the condition from 0 (latent) to III (elephantiasis) to guide treatment.
- 03
Assessing
Limb volume measurement
Circumferential tape measurements or perometry establish a baseline and track response to therapy over time.
- 04
Confirming
Duplex ultrasound scan
Excludes chronic venous insufficiency or deep vein thrombosis as the cause or a contributing factor.
- 05
Confirming
Lymphoscintigraphy
Used selectively in uncertain cases to visualise lymphatic flow and confirm impaired drainage.
- 06
Preparing
Genetic testing where relevant
Considered for suspected primary lymphoedema, particularly with early onset or a family history, such as Milroy disease.
- 07
Preparing
Referral to a specialist service
MDT-led, commissioned lymphoedema services coordinate compression therapy, exercise plans and surgical opinion where needed.
Typical timeline: a first assessment to a settled therapy plan in a few weeks.
Symptoms
What lymphoedema actually looks like.
The classic mix of swelling, heaviness and skin change - and the features that mean it's time to seek urgent care.
-
Limb or area swelling
The defining feature - persistent swelling of an arm, leg or other area that does not resolve with elevation.
-
Heaviness and aching
A dragging or tight sensation, often worse by the end of the day or after activity.
-
Skin thickening and changes
Over time, skin can become firm, fibrotic and thickened - a feature of more advanced disease.
-
Positive Stemmer sign
Inability to pinch and lift a fold of skin at the base of the second toe or finger - a reliable diagnostic clue.
-
Recurrent cellulitis
Swollen limbs are prone to repeated skin infections, which in turn can worsen lymphatic damage.
-
Psychological and quality-of-life impact
Visible swelling, clothing difficulties and activity limits carry a real emotional and social burden.
-
Congenital or early-onset swelling
Primary lymphoedema can appear at birth (Milroy disease), around puberty (praecox) or later in adulthood (tarda).
-
Red flag - rapid worsening or redness
Sudden deterioration, spreading redness or fever needs urgent assessment for cellulitis or another cause.
Treatment
How lymphoedema is treated in the UK.
Complete decongestive therapy first, lifelong maintenance compression next - and surgery for carefully selected severe cases.
-
Complete decongestive therapy
The gold-standard approach - manual lymphatic drainage, multi-layer compression bandaging, exercise and skin care combined.
-
Manual lymphatic drainage
A specialised, gentle massage technique that encourages fluid to move towards working lymphatic pathways.
-
Multi-layer compression bandaging
Reduces swelling during the intensive phase of treatment, before a maintenance garment is fitted.
-
Maintenance compression garments
Custom-fitted, worn lifelong to sustain the volume reduction achieved during intensive therapy.
-
Pneumatic compression devices
Intermittent pneumatic pumps used alongside garments for selected patients to support fluid movement.
-
Skin care and infection prevention
Meticulous daily skin care and prompt treatment of any wound - cellulitis prevention is central to long-term care.
-
Graduated exercise
Structured, progressive activity that supports the muscle pump - it does not worsen lymphoedema when done correctly.
-
Surgical options
Lymphovenous anastomosis and vascularised lymph node transfer, reserved for severe or treatment-resistant disease.

Red flags
When lymphoedema needs urgent attention.
Most lymphoedema is managed through routine specialist care. These are the situations that aren't - and where urgent review is needed.
-
Acute cellulitis
Sudden redness, warmth, spreading pain or fever over a swollen limb needs urgent antibiotics and same-day assessment.
-
Rapidly worsening swelling
Fast progression can point to infection, a new deep vein thrombosis, or - rarely - tumour compression of the lymphatics.
-
A new lump or hardening
An unexplained new mass or area of induration should be checked to exclude recurrence or, very rarely, lymphangiosarcoma.
-
Suspected deep vein thrombosis
Sudden one-sided swelling with calf pain and warmth needs same-day assessment (see our deep vein thrombosis guide).
-
Skin breaks or weeping
Open areas or weeping skin raise the risk of infection and need prompt wound care from a specialist nurse or GP.
-
Truncal, groin or genital swelling
Swelling beyond a limb needs specialist assessment, as standard limb protocols may not fully apply.
-
Suspected malignant lymphoedema
Swelling caused by tumour compression of lymphatic channels needs oncology input alongside standard lymphoedema care.
-
Significant psychological distress
Low mood, anxiety or body-image distress related to swelling deserve psychological support alongside physical treatment.
-
Suspected Klippel-Trenaunay syndrome
Congenital limb swelling with vascular birthmarks and overgrowth needs specialist vascular review (see our Klippel-Trenaunay guide).
Living with it
A lifelong condition, with a clear routine.
Four things that make the biggest difference day to day - skin vigilance, consistent compression, gentle movement and knowing where to find support.
A quiet reminder
Consistency, not intensity, keeps swelling controlled.
Small daily habits - kept up for years - do more than an intensive week that isn't followed through.
- 01 Skin
Guard against infection
Check your skin daily, moisturise well and treat cuts or grazes immediately - this is the single most important daily habit.
- 02 Compress
Wear your garment every day
Maintenance compression only works if it is worn consistently - most flare-ups follow a gap in wear, not a single bad day.
- 03 Move
Keep moving
Graduated exercise and everyday muscle pump activity support drainage and do not make lymphoedema worse.
- 04 Support
Reach out for support
The Lymphoedema Support Network and local commissioned services can help with the practical and emotional load of living with it.
Frequently asked
Everything we get asked about lymphoedema.
Quick answers on causes, compression, maintenance garments and surgery.
-
What is lymphoedema?
A chronic, progressive condition where protein-rich lymph fluid builds up in tissue because the lymphatic system cannot drain it properly. It most often affects an arm or leg and causes swelling, heaviness and, over time, skin changes.
-
What is the difference between primary and secondary lymphoedema?
Primary lymphoedema is caused by a congenital fault in the lymphatic system, appearing at birth, around puberty or in adulthood. Secondary lymphoedema is far more common and develops after damage to the lymphatic system, most often from cancer treatment, infection, trauma or chronic venous disease.
-
Why does breast cancer treatment cause arm lymphoedema?
Removing or irradiating the lymph nodes under the arm during breast cancer treatment can permanently reduce the lymphatic system’s capacity to drain the arm, leading to swelling that can appear months or years after treatment finishes.
-
What is complete decongestive therapy?
It is the gold-standard treatment - a combination of manual lymphatic drainage, multi-layer compression bandaging, guided exercise and careful skin care, usually delivered in an intensive phase followed by long-term maintenance with a compression garment.
-
Do I need to wear a compression garment forever?
For most people with established lymphoedema, yes - maintenance compression is usually lifelong. Stopping typically allows the swelling to return, so garments are refitted and replaced regularly as part of ongoing care.
-
Can lymphoedema be cured with surgery?
Surgery is not a routine cure. Lymphovenous anastomosis and vascularised lymph node transfer can meaningfully reduce swelling and the burden of compression for selected patients with severe or treatment-resistant disease, but most people continue some level of conservative management afterwards.
