Varicose Veins and Manual Therapy: What You Need to Know

What Are Varicose Veins?

Varicose veins are dilated, tortuous superficial veins — most commonly of the lower limbs — resulting from incompetence of the venous valves that normally prevent retrograde blood flow. Under normal conditions, venous blood is returned to the heart against gravity through a combination of muscular contraction, respiratory pressure changes, and one-way venous valves. When valve leaflets fail to close competently, blood pools in the dependent vein segments, causing progressive dilatation, wall weakening, and the characteristic bluish, bulging, ropy appearance visible beneath the skin surface.

Varicose veins affect approximately 20–30% of adults in Western populations, with a higher prevalence in females and increasing incidence with age, prolonged standing occupations, pregnancy, obesity, and family history. Symptoms range from cosmetically bothersome but painless visible vessels to significant aching, heaviness, itching, oedema, and skin changes indicative of chronic venous insufficiency.

Clinical Implications for Manual Therapy

Varicose veins are not an absolute contraindication to manual therapy, but they require informed clinical decision-making regarding technique, pressure, and anatomical location. The primary risk is not the varicose vein itself but rather the potential to disturb thrombus in an associated deep vein — a concern that applies wherever venous disease is present in the lower limb.

Crucially, deep vein thrombosis (DVT) must be actively excluded before performing lower limb massage in patients with known or suspected varicose vein disease. The clinical signs of DVT — calf pain, warmth, oedema, Homan's sign (though low specificity), and skin colour change — should prompt deferral and urgent medical assessment rather than treatment. This is a genuine clinical red flag: pulmonary embolism arising from DVT dislodgement by massage is a documented and preventable outcome.

For patients with confirmed uncomplicated varicose veins, manual therapy of the surrounding musculature is generally safe. Techniques applied directly over varicosities — deep friction, strong compression, or high-speed strokes — should be avoided. Oedema associated with chronic venous insufficiency may respond to manual lymphatic drainage (MLD) techniques; these involve light, rhythmic, directional strokes designed to encourage lymph flow rather than deep tissue manipulation.

Absolute and Relative Contraindications

The following represent contraindications to direct massage over or around the varicosity or affected limb: active DVT (absolute contraindication); acute thrombophlebitis characterised by warmth, redness, pain, and induration over the vessel (absolute); recent endovascular treatment (sclerotherapy, thermal ablation) within four to six weeks (relative, pending practitioner guidance); severe chronic venous insufficiency with active leg ulceration (relative — wound care takes priority). Compression garments are often recommended post-treatment for all varicose vein presentations to support venous return and should be worn during manual therapy sessions where relevant.

Exercise and Lifestyle Management

The gastrocnemius and soleus complex constitutes the primary venous pump for the lower limb — its rhythmic contraction during walking and standing compresses the deep venous plexus and drives blood proximally. Regular ambulation, calf raises, and cycling are highly effective conservative management strategies for symptomatic varicose veins. Prolonged standing should be interspersed with active movement; elevation of the legs above heart level during rest periods reduces pooling and oedema. Weight management and compression therapy provide meaningful symptomatic relief. Patients with symptoms beyond the cosmetic — persistent oedema, skin changes, superficial thrombophlebitis, or haemorrhage from superficial varices — warrant vascular surgery referral for consideration of endovenous ablation, sclerotherapy, or surgical stripping.
