NICE varicose veins leg swelling duplex ultrasound referral guideline
New below-knee swelling with a history of varicose veins needs an in-person assessment soon, ideally today or within 24-48 hours, particularly if it is mainly in one leg. Varicose veins can cause chronic venous insufficiency with swelling, but a deep-vein thrombosis (DVT, blood clot) must first be ruled out.
The photo alone cannot confirm the cause. I do not see an obvious open ulcer or marked redness in this image, but a photograph cannot assess a clot, vein reflux, warmth, tenderness, or arterial circulation.
Seek urgent emergency care now if any of these are present
- Sudden or rapidly increasing swelling of one leg
- New calf pain/tenderness, warmth, redness, or a hard painful vein
- Shortness of breath, chest pain, coughing blood, fainting, or rapid heartbeat
- Fever with a red, hot, painful leg
- Bleeding from a varicose vein
Whom to consult
Consult a vascular surgeon or a vascular medicine specialist. If unavailable, start with a general physician/internal-medicine doctor today, who can arrange the scan and referral.
Most useful test
-
Colour duplex venous Doppler ultrasound of the affected leg
- Ask for assessment of both:
- Deep veins: to exclude DVT
- Superficial veins and venous reflux: to map incompetent valves causing varicose veins
Duplex ultrasound is the standard assessment for symptomatic varicose veins and treatment planning, according to NICE guidance.
- Ask for assessment of both:
-
Additional tests only if the doctor finds an indication
- D-dimer blood test, if DVT probability is assessed as low/intermediate
- CBC, kidney/liver function, thyroid testing, urine protein, glucose, etc., if swelling is bilateral or another systemic cause is suspected
- Ankle-brachial pressure index (ABPI) before prescribing stronger compression stockings, especially with diabetes, smoking history, foot pain on walking, or weak foot pulses
What to do until reviewed
- Do not massage the calf or use unprescribed blood thinners.
- Walk gently and avoid long periods sitting or standing. During travel, move ankles and walk regularly.
- Elevate the leg above heart level for 20-30 minutes, several times daily.
- Avoid tight clothing around the thigh or knee.
- Compression stockings can help venous swelling, commonly 20-30 mmHg for uncomplicated varicose veins, but because this is new swelling, it is safer to start them after a clinician has excluded DVT and significant arterial disease. Harrison’s notes that chronic venous disease may progress from varicose veins to edema, skin change, and ulcers, and that graduated compression is commonly used for symptoms (Harrison’s Principles of Internal Medicine, 22E, Chronic Venous Disease).
If the Doppler shows reflux without a clot, the vascular specialist can discuss options such as compression, endovenous laser/radiofrequency ablation, foam sclerotherapy, or phlebectomy. Symptomatic swelling is itself a valid reason for vascular referral, as noted in the NICE referral criteria.
A recent evidence review supports current guideline-based management, but does not change the priority here: first exclude DVT, then assess venous reflux. Relevant recent guideline: PMID 37652254.

NHS deep vein thrombosis symptoms swollen leg hard tender urgent
If the swelling is solid/firm rather than soft or pitting, please arrange a same-day medical examination and a venous colour Doppler ultrasound. A firm swollen calf can occur with chronic venous changes, a clotted superficial varicose vein, inflammation/infection, or less commonly a DVT. It cannot be distinguished safely by touch or photo alone.
Go to emergency care today if it is one-sided and new, enlarging, painful/tender, warm, red/dark, or if a vein feels like a painful hard cord. Seek emergency help immediately for chest pain, breathlessness, fainting, or coughing blood.
Until assessed:
- Do not massage or vigorously rub the area.
- Do not start aspirin or blood thinners on your own.
- Do not use tight compression stockings until DVT and poor arterial circulation have been assessed.
- Gentle walking is fine if comfortable, but avoid prolonged standing or sitting.
Consult a vascular surgeon/vascular specialist. If one is not readily available, see a general physician or emergency department today to arrange the Doppler. Hard, sore swollen veins are among the features that need assessment for clotting, as described by NHS DVT guidance.

NICE varicose veins painful hard veins superficial thrombophlebitis referral
This picture clearly shows prominent, bulging varicose veins around the upper calf/below-knee area. I do not see an obvious open wound or marked redness in the photo, but a photo cannot rule out a clot within a superficial vein or a deep vein.
Because she has:
- long-standing varicose veins
- new swelling
- a firm/solid feeling area
she should have a venous colour Doppler ultrasound of the whole leg today or within 24 hours. Request assessment for:
- DVT in deep veins
- Superficial vein thrombosis/thrombophlebitis
- Venous valve reflux due to varicose veins
The firm area could be chronic venous swelling, but if the visible vein or lump is hard, painful, warm, or increasingly swollen, superficial vein thrombosis is possible. Varicose veins are a common setting for this. A thrombosed varicose vein can become tender, raised, red, and indurated, sometimes with leg swelling (Bailey and Love’s Short Practice of Surgery, 28th ed., Varicose Veins).
Consult: a vascular surgeon or vascular specialist. If Doppler is not easily available through a clinic, go to an emergency department or general physician today for urgent evaluation and a Doppler referral.
Until she is examined:
- No massage or rubbing of the swelling.
- Do not start aspirin, anticoagulants, or pain medicines other than simple paracetamol unless prescribed.
- Avoid prolonged standing and sitting; gentle walking is acceptable if not painful.
- Elevate the leg when resting.
- Do not begin firm compression stockings until the doctor has excluded DVT and checked circulation.
Emergency now if chest pain, shortness of breath, fainting, coughing blood, rapidly worsening one-leg swelling, or a very painful/red/hot calf occur. Symptomatic varicose veins and hard painful veins warrant vascular assessment under NICE recommendations.
What do you think is the management of this case based on, uh, different findings seen in venous Doppler ultrasound?
Reading File
Quick answer
Management depends mainly on whether Doppler shows deep-vein clot, superficial-vein clot, reflux (leaky valves), or obstruction.
| Venous Doppler finding | Likely meaning | Usual management |
|---|---|---|
| Normal deep and superficial veins, no reflux/clot | Swelling may not be primarily venous | Doctor evaluates other causes: lymphedema, knee/Baker cyst, infection, medicines, kidney/heart/liver/thyroid disease. Compression only after arterial circulation is considered adequate. |
| Superficial varicose veins with reflux, but no clot | Chronic venous insufficiency from incompetent valves, likely the common scenario here | Leg elevation, walking/calf exercises, weight management if relevant, skin moisturising, and properly fitted graduated compression stockings after assessment. Refer to vascular surgeon for definitive treatment if symptoms/swelling persist: endovenous laser or radiofrequency ablation is usually preferred; foam sclerotherapy or phlebectomy may be used for residual visible veins. |
| Great saphenous vein or small saphenous vein reflux with large symptomatic varicosities | Treatable source of varicose veins | Vascular specialist plans endovenous ablation of the refluxing trunk, often followed by phlebectomy or foam treatment of branches. Do not treat just the surface veins without mapping the underlying reflux. |
| Superficial vein thrombosis / thrombophlebitis in a varicose vein | A clot in a surface vein. It can cause a firm, tender cord/lump, sometimes redness and swelling | Urgent vascular/medical review. Ultrasound must document clot length and distance from the deep-vein junctions. Elevation, walking as tolerated, analgesia/anti-inflammatory treatment if appropriate, and compression only as advised. Anticoagulation is commonly needed if clot is extensive, near the saphenofemoral or saphenopopliteal junction, worsening, or there are clot-risk factors. Repeat Doppler may be needed to ensure it is not extending. Definitive varicose-vein treatment is usually planned after the acute episode settles. |
| Superficial clot close to the deep system, or extending into deep veins | Higher risk of DVT/pulmonary embolism | Treat as DVT with therapeutic anticoagulation under a physician/vascular specialist, with urgent assessment. |
| Acute deep-vein thrombosis (DVT) | A deep clot, which cannot be safely managed as ordinary varicose veins | Same-day treatment by emergency/medical/vascular team. Anticoagulation is the main treatment unless contraindicated. The duration and drug choice depend on whether it is provoked, extent/location, bleeding risk, kidney function, cancer/pregnancy status, and previous clots. Do not massage the leg or undergo varicose-vein procedures during acute DVT. Seek emergency care immediately for breathlessness, chest pain, fainting, or coughing blood. |
| Old/chronic DVT with residual obstruction or post-thrombotic changes | Previous clot has damaged valves or narrowed the vein | Specialist assessment. Compression and exercise may help symptoms; management focuses on swelling, skin protection, and ulcer prevention. In selected severe proximal obstruction, a vascular team may consider further imaging and venous intervention such as stenting. Superficial vein ablation needs careful planning because those veins may be important drainage pathways. |
| Deep venous reflux without acute DVT | Deep vein valves are incompetent | Usually conservative treatment first: compression if safe, elevation, exercise, skin care. Treating superficial reflux may still help in selected patients, but this must be decided after full mapping by a vascular specialist. |
| Perforator reflux with skin pigmentation, eczema, hard lower-leg skin, or ulcer | More advanced chronic venous disease | Compression and meticulous skin/ulcer care. Vascular referral for treatment of superficial reflux, and sometimes perforator treatment. A nonhealing ulcer needs wound-care and vascular management. |
For this case
Given the visible varicose veins plus new firm swelling, the Doppler request should explicitly state:
“Venous colour Doppler of affected lower limb: assess for DVT, superficial venous thrombosis, great and small saphenous reflux, perforator incompetence, and deep venous reflux/obstruction.”
If the report says “no DVT, no SVT, but significant saphenofemoral/great saphenous reflux”, this is usually managed non-emergently by a vascular surgeon, with planned endovenous treatment after clinical examination.
If it says “SVT” or “DVT”, the patient needs prompt physician/vascular review the same day, because management may include anticoagulation rather than simply stockings or vein procedures.
Patient says there is past history of similar swelling in the hip region. Which, uh, came and she didn't, uh, go for any treatment. It went on its own.
Reading File
Quick answer
That history is important. A previous swelling near the hip that settled on its own could have been unrelated, but together with current firm leg swelling and varicose veins it raises concern for an intermittent vein problem, including a possible episode of superficial vein thrombosis that resolved.
It does not prove a clot, but makes it more important not to assume this is only uncomplicated varicose veins.
What to tell the doctor/Doppler centre
Ask for:
Whole-leg venous colour Doppler including common femoral vein, saphenofemoral junction, great and small saphenous veins, assessment for superficial thrombosis, DVT, reflux, and proximal/iliac venous obstruction if technically possible.
If the current swelling is on the same side as the prior hip/groin swelling, mention that specifically. If Doppler is negative but there is significant recurrent one-sided swelling, the vascular specialist may consider imaging of pelvic/iliac veins, because a standard leg Doppler may not fully visualize them.
Important history to provide
Tell the clinician about:
- Exact side and location of the old “hip” swelling: groin, upper thigh, buttock, or side of hip
- Whether it was painful, red, warm, hard, or associated with a visible vein
- Recent travel/immobility, surgery, injury, injections, hormone tablets, smoking, prior pregnancy-related clot, family history of clots, or cancer history
- Any weight loss, persistent fever, night sweats, or recurring unexplained lumps
Urgency
Please arrange assessment today or within 24 hours. Go to emergency care immediately for chest pain, breathlessness, fainting, coughing blood, or rapidly worsening pain/swelling.
the swelling increased to current size in one month's time.
Reading File
Quick answer
A firm, one-sided swelling that has progressively enlarged over one month should not be treated as simple varicose veins without investigation.
It could still be worsening chronic venous insufficiency, but important alternatives include:
- Superficial venous thrombosis in a varicose vein
- DVT or old clot causing partial venous blockage
- Proximal obstruction higher in the thigh/pelvis, especially given the earlier hip/groin-region swelling
- Lymphedema
- Less commonly, a soft-tissue lump, enlarged lymph node, or other pelvic/abdominal cause compressing venous/lymphatic drainage
What to do now
Arrange same-day or next-day in-person evaluation with a vascular surgeon, general physician, or emergency department if no urgent appointment is available.
Ask for:
Urgent whole-leg venous colour Doppler, including deep veins, superficial veins, reflux mapping, superficial thrombosis, common femoral/saphenofemoral junction, and assessment for proximal venous obstruction.
If the leg Doppler is normal but the swelling remains substantial or is clearly one-sided, the doctor should consider pelvic/iliac venous imaging and examination for a non-venous lump.
Until reviewed
- Do not massage the swelling.
- Do not self-start aspirin or blood thinners.
- Avoid prolonged sitting/standing and elevate the leg when resting.
- Hold off on strong compression stockings until DVT and arterial circulation have been assessed.
Go to emergency care immediately for new/worsening pain, redness, warmth, rapidly increasing size, breathlessness, chest pain, fainting, or coughing blood.
