Pelvic congestion syndrome: why the pain is coming from your veins
Pelvic congestion syndrome is chronic pelvic pain caused by veins in the pelvis that no longer drain properly. Instead of carrying blood upwards towards the heart, the ovarian and pelvic veins allow it to fall back down and pool. The vein walls stretch, pressure rises through the day, and the result is a heavy, dragging ache that is usually worst by evening and eases when you lie flat.
A circulation problem that looks like a gynaecological one
The reason this condition is missed so often is that the pain is felt where gynaecological disease is expected. Scans done lying down can look reassuring, because gravity is no longer loading the veins. Many patients are investigated for months, told their reports are normal, and left with the impression that the pain has no physical cause. It does — it is simply being looked for in the wrong system.
The clues are in the pattern rather than the location. Pain that builds with standing, discomfort after intercourse, visible veins around the vulva, buttock or inner thigh, and varicose veins that come back soon after apparently successful leg treatment all point towards pelvic vein reflux feeding the problem from above.
What patients describe
- Chronic pelvic pain
A dull, dragging ache low in the abdomen lasting longer than six months, often described as heaviness rather than a sharp pain.
- Pain before periods
Discomfort that builds in the days leading up to menstruation as pelvic veins engorge under hormonal influence.
- Pain after standing
Symptoms worsen through the working day, after long hours standing, travelling or sitting, and settle when you lie down.
- Pain during or after intercourse
Deep dyspareunia, or an ache that begins during intercourse and lingers for hours afterwards, is a classic venous pattern.
- Pelvic heaviness or fullness
A sensation of pressure or bearing down in the pelvis, sometimes with urinary urgency or bloating.
- Lower back and hip ache
Congested pelvic veins refer pain to the sacrum, buttock and upper thigh, which is often mistaken for a spine problem.
- Visible pelvic, vulval or thigh veins
Prominent veins on the vulva, buttock, inner thigh or behind the knee — and varicose veins that return after leg treatment.
Who tends to develop it
- Two or more pregnancies — pelvic vein diameter increases substantially during pregnancy and may not fully recover
- Age between 20 and 45 years, when ovarian hormonal activity is highest
- Family history of varicose veins or valve weakness in the veins
- Existing leg varicose veins, especially veins that recur after previously successful treatment
- Occupations requiring prolonged standing or long seated hours — teachers, nurses, IT professionals, retail and hospitality staff
- Polycystic ovarian disease and other conditions associated with pelvic vein dilatation
- Anatomical vein compression such as May-Thurner syndrome (left iliac vein) or nutcracker syndrome (left renal vein)
- Previous pelvic surgery, pelvic inflammatory disease or pelvic trauma
Conditions it is commonly confused with
Cyclical pain, deep dyspareunia and pelvic heaviness overlap almost completely with endometriosis, adenomyosis, ovarian cysts and chronic pelvic inflammatory disease. When a laparoscopy is normal, the pain is often labelled unexplained rather than investigated as venous.
Bloating, lower abdominal discomfort that worsens through the day and variable bowel habit lead many women down an irritable bowel syndrome pathway, with endoscopy and dietary trials that never address the underlying vein.
Pelvic pressure and urinary urgency without infection are frequently treated as recurrent urinary tract infection, interstitial cystitis or an overactive bladder.
Referred sacral, buttock and thigh ache that is worse on standing invites lumbar imaging, physiotherapy and sometimes injections before the veins are ever imaged.
Because symptoms fluctuate with the cycle and worsen with fatigue, many women are told the pain is hormonal, psychological or simply part of being a woman — and stop seeking answers.
A routine pelvic ultrasound performed lying down, without Valsalva and without interrogating the ovarian veins, can look entirely normal in a woman with significant reflux. The diagnosis needs a scan specifically aimed at the venous system.
How the diagnosis is confirmed
A structured pain history — timing, posture, cycle relationship, obstetric history and previous vein treatment — combined with examination for vulval, thigh and buttock varicosities. This step alone reclassifies many women who have been investigated for years without a venous explanation.
A painless duplex scan of the abdomen, pelvis and legs measures ovarian vein diameter, demonstrates reversed (retrograde) flow on Valsalva manoeuvre, and maps any leg reflux feeding from the pelvis.
Performed where appropriate, it visualises dilated para-uterine and para-ovarian veins at close range and helps exclude fibroids, adenomyosis, ovarian cysts and endometriomas.
A contrast CT provides a complete road map of the ovarian, renal and iliac veins, identifies compression syndromes, and rules out non-venous abdominal causes of pain.
Radiation-free cross-sectional imaging that is particularly useful in younger women and where soft-tissue detail of the uterus and ovaries matters alongside the venous anatomy.
The reference standard. Through a tiny vein puncture, contrast is injected directly into the ovarian and internal iliac veins to confirm reflux and pelvic varices — and, in the same sitting, treatment can be delivered.
What treatment involves
Not every woman with pelvic vein reflux needs a procedure. Where symptoms are mild, pain is managed and the veins are monitored. Where scanning confirms significant reflux and the pain pattern matches, the refluxing veins can be closed from inside through a small vein puncture — ovarian vein embolization, a day-care treatment done under local anaesthesia.
Assessment, scanning and treatment are all run through the Pelvic Vein Clinic at Renova Century Hospital, Banjara Hills. If leg veins keep returning after treatment, the varicose veins assessment includes checking the pelvic veins above them.
