Introduction
Varicose veins are enlarged, twisted superficial veins most often seen in the legs. They develop when vein valves weaken and blood pools instead of flowing efficiently toward the heart.
Symptoms may include aching, heaviness, swelling, and visible bulging veins. While often a cosmetic concern, advanced disease can lead to skin changes and ulcers.
Treatment ranges from compression and lifestyle measures to minimally invasive procedures that close or remove faulty veins with good long-term relief for many patients.
This page explains common symptoms, how evaluation usually proceeds, treatment options, and when to seek medical care.
Overview
Chronic venous insufficiency underlies most varicose veins. Risk increases with age, family history, pregnancy, obesity, and prolonged standing.
Modern endovenous therapies have largely replaced extensive surgical stripping for many patients, with faster recovery and durable results.
- Dilated superficial leg veins with valve failure
- Common and often run in families
- Cause aching, swelling, and cosmetic concern
- Compression stockings are first-line therapy
- Minimally invasive closure procedures available
- Progression may lead to skin ulcers
What happens in the body
Incompetent venous valves allow retrograde blood flow and venous hypertension. Increased pressure dilates vein walls and promotes inflammation in surrounding tissue.
Over time, microvascular leakage causes ankle swelling, hyperpigmentation, lipodermatosclerosis, and ulcer formation in severe chronic venous disease.
- Valve incompetence increases venous pressure
- Blood reflux pools in superficial veins
- Chronic hypertension damages vein wall and skin
- Inflammatory mediators worsen edema and fibrosis
Signs and symptoms
Common symptoms and warning signs may include:
- Visible twisted blue or purple leg veins
- Leg heaviness worse after standing
- Ankle swelling especially evening
- Aching or throbbing pain
- Itching over affected veins
- Night cramps
- Skin darkening near ankles when advanced
- Bleeding from superficial vein rupture (rare)
Causes and risk factors
Possible causes and contributing factors include:
- Inherited valve weakness
- Age-related vein elasticity loss
- Pregnancy hormonal and pressure effects
- Obesity increasing venous load
- Prolonged standing or sitting
- Prior deep vein thrombosis damaging valves
- Female sex and multiparity
Diagnosis and evaluation
Evaluation may include:
- Clinical examination with patient standing
- Duplex ultrasound mapping reflux
- CEAP clinical classification staging
- Exclude deep venous thrombosis when acute leg swelling
- Ankle-brachial index if arterial disease suspected
- Photography for treatment planning and follow-up
Treatment and management
Treatment and management may involve:
- Graduated compression stockings daily
- Leg elevation and regular walking
- Weight management when applicable
- Endovenous laser or radiofrequency ablation
- Foam sclerotherapy for tributaries
- Ambulatory phlebectomy for selected bulging veins
- Treat skin ulcers with compression and wound care
- Avoid prolonged immobility
Prevention, self-care, and lifestyle
Not every condition is fully preventable, but the steps below may lower risk or recurrence:
- Stay active and avoid long uninterrupted standing
- Maintain healthy weight
- Use compression during pregnancy if symptomatic and advised
Possible complications
Delay, missed care, or unsafe self-medication can raise the chance of complications in some cases:
- Superficial thrombophlebitis
- Venous leg ulcers
- Lipodermatosclerosis and stasis dermatitis
- Bleeding from varicosity
- Reduced quality of life from pain or appearance
When to see a doctor or seek emergency care
Seek prompt medical advice or emergency care if any of the following apply—it is safer not to wait and see:
- Sudden painful swollen leg suggesting DVT
- Skin breakdown or nonhealing ankle wound
- Sudden heavy bleeding from a vein
- Severe symptoms limiting daily activity
Living with the condition
Wear compression stockings in the morning before swelling builds, and replace them every few months as elasticity fades. Regular walking activates calf muscle pumps that support venous return.
Frequently asked questions
Do varicose veins always need surgery?
No. Many people manage with compression and lifestyle changes. Procedures are considered for significant symptoms, progression, or complications.
Can varicose veins return after treatment?
Treated veins usually stay closed, but new varicosities may develop elsewhere because underlying predisposition remains. Ongoing compression helps maintenance.
