What is varicose vein disease?
Varicose veins (medically called chronic venous insufficiency or varicose veins) refer to dilation and tortuosity of the veins, most commonly on the lower leg. Your veins contain small valves that prevent blood from flowing backward. When these valves are damaged or weakened, blood pools in the veins. With increasing pressure, the vessel wall stretches and becomes tortuous — this is how the characteristic bluish varicose veins appear.
It’s important to understand: varicose veins are not merely a cosmetic problem. In the early stages they may still be reversible, but without treatment they can progress gradually and lead to serious complications — leg ulcers, thrombosis.
Key idea
Varicose vein disease is a disorder of venous return: in dilated, valve-defective veins blood pools, causing leg swelling and fatigue. The cornerstone of home treatment is regular movement (calf muscle pump) and compression therapy. If active movement is not possible, home devices (muscle stimulator, pneumatic compression) can support the muscle-pump effect. Symptoms appearing after previous deep vein thrombosis are covered in the thrombosis articles.
How does it develop? – Venous circulation and the muscle pump
The natural engine of your leg venous circulation is the calf muscle pump. When you move — walk, stroll, run, climb stairs — the rhythmic contraction of your calf muscles "pumps" blood upward toward your heart. This muscle pump effect is essential for venous return.
However, if you sit or stand still for long periods, the muscle pump doesn’t work — blood begins to pool in the veins. The increasing hydrostatic pressure gradually dilates the vessel wall and damages the venous valves: this is the initiating mechanism in the development of varicose vein disease.
Because of the stagnant blood, protein and fluid leak into the surrounding tissues — this causes swelling, tightness, and over time the skin’s brownish-purple discoloration (hemosiderin) and skin hardening.
Stages of varicose vein disease – CEAP classification
The severity of varicose vein disease is described in vascular surgery with the CEAP system (Clinical, Etiological, Anatomical, Pathophysiological). The clinical (C) stage is what you can recognize at home in the mirror:
| Stage | Characteristic |
|---|---|
| C0 | No visible or palpable varicose veins – but symptoms may already be present (heavy-leg sensation) |
| C1 | Small vessels (telangiectasia, "spider veins"): thin, hairlike, bluish-purple |
| C2 | Classic, tortuous varicose veins (varicose veins), ≥3 mm diameter |
| C3 | Leg swelling (edema) – by the end of the day, mainly around the ankle |
| C4 | Skin changes: brownish pigment (hemosiderin), eczema, lipodermatosclerosis |
| C5 | Healed venous leg ulcer (scar) |
| C6 | Active, open venous leg ulcer |
In stages C0–C2, lifestyle changes at home and compression therapy can provide the best results. From C3 onward, adjunctive physiotherapy (EMS, pneumatic compression) is particularly recommended. In stages C5–C6 specialist vascular (surgical) care is necessary — for home aftercare you can choose between two parallel modalities: venous leg ulcer treatment with muscle stimulation (EMS) or leg ulcer treatment with soft laser (the two can be combined).
Symptoms of varicose vein disease
Varicose vein disease usually develops gradually. Recognize the signs in time:
Visible varicose veins – Twisted, swollen, bluish-purple veins are visible under the skin, most commonly on the lower leg and calf. This is the first visible sign that many consider merely an aesthetic problem.
Heavy-leg sensation – Legs feel "lead-heavy", tired, especially after prolonged standing or sitting. This is often the first symptom that draws attention to the problem.
Leg swelling – If the edge of your sock leaves a groove in your skin, that is already a warning sign. The foot, ankles, or even the lower leg can become edematous, especially by the end of the day. The differential diagnosis of leg edema (varicose vs. lymphoedema vs. lipedema vs. cardiac/renal) is discussed in the leg swelling triage article.
Itching and burning – Itching in the affected area may indicate slowed circulation. Burning, throbbing sensations or nighttime muscle cramps may also occur.
Skin changes – In advanced stages the skin may discolor to a purplish-brown and thicken. This is a sign of hemosiderin deposition — read more in the Reddish-brown spot on the lower leg – What is it? article.
Ulcer – The most serious complication: a wound that does not heal or heals very slowly, usually around the ankle. Home treatment options include muscle stimulation (EMS) and soft-laser therapy. If the ulcer becomes infected (erysipelas), read the erysipelas – bacterial skin infection article.
What causes varicose vein disease?
Several factors play a role in the development of varicose veins:
Heredity – If family members have it, your risk is higher. Weakness of connective tissue can be inherited.
Lifestyle – This is the most important factor you can influence! A sedentary lifestyle, prolonged standing or sitting directly leads to varicose vein disease.
Age – The older you are, the higher your risk. In the 60–69 age group about 25% are affected by varicose vein disease.
Sex – Women are twice as likely to be affected as men. This is due to weaker connective tissue and differences in vessel wall structure.
Hormonal factors – Birth control pills, pregnancy and hormonal changes increase the risk. You can read about pregnancy-specific varicose vein problems in the pregnancy varicose vein article.
Obesity and smoking – Both are significant modifiable risk factors.
Varicose veins and thrombosis risk
Varicose vein disease is not the same as thrombosis, but it increases the risk of thrombosis. Stagnant, slow-flowing venous blood (venous stasis) is one element of Virchow’s classic triad — the other two are vessel wall injury and increased coagulability. In severe varicose veins superficial thrombosis (phlebitis) is more common, and statistically the risk of deep vein thrombosis (DVT) is higher.
However, this is a risk factor, not a direct cause-and-effect chain: people can live with varicose veins for decades without thrombosis if lifestyle protective factors (movement, compression, hydration, ideal body weight) are maintained.
When is an URGENT medical examination needed?
- Sudden, significant one-sided leg, calf or ankle swelling developing within half a day;
- warmth, redness in a localized area with pain that increases on touch;
- chest pain, shortness of breath, sudden coughing (possibly with bloody sputum) — call emergency services (104 / 112): suspicion of pulmonary embolism.
The detailed clinical picture of thrombosis, home actions and treatment of post-thrombotic syndrome are available in the thrombosis article.
Treatment of varicose vein disease — what you can do yourself
Regular exercise – the cornerstone of home treatment
For both prevention and treatment, regular physical activity is the most important factor. Recommended activities:
- walking, brisk walking;
- Nordic walking;
- cycling;
- swimming;
- running (if your condition allows).
The point: aim for at least 30–40 minutes daily. If you have a sedentary job, stand up every hour, walk for a few minutes and move your legs.
Lifestyle advice
- Don’t use the elevator — take the stairs!
- Wear flat, flexible-soled shoes (heels no higher than 5 cm).
- Avoid heat: sunbathing, saunas, thermal baths.
- If your legs swell, elevate them frequently.
- Don’t sit with your legs crossed.
- High-fiber diet, reduced salt.
- Maintain a healthy body weight.
Compression therapy
Compression stockings or bandages are a fundamental tool in treating varicose veins. Important to know: compression garments are most effective when you move while wearing them. If you sit motionless with a bandage on, its elasticity cannot take effect.
The appropriate compression strength should be selected by a professional. Don’t buy compression stockings by guesswork — the wrong strength can do more harm than good. According to the modern European consensus recommendation (Rabe et al. 2022), from CEAP C2 upward a minimum of 20–30 mmHg compression is recommended; for asymptomatic preventive use 15–20 mmHg may be sufficient.
Home devices – physiotherapy
If your condition prevents regular physical activity — for example due to mobility limitations, severe joint problems, or advanced varicose vein disease — home medical devices can support the muscle-pump effect.
Muscle stimulator (EMS) device
The muscle stimulator device uses electrical impulses to trigger contraction of the calf muscles — exactly mimicking what happens while walking. During a 20–30 minute treatment the rhythmic contraction of the muscles "pumps" blood out of the veins.
This method is particularly recommended for:
- mild to moderate varicose complaints (CEAP C0–C2);
- if you are unable to perform active exercise;
- as a supplement to daily physical activity.
Rehalito EMS muscle stimulator
Simple, affordable, 2-channel device. Designed specifically for rehabilitation and circulation improvement. An ideal choice if you primarily need activation of the calf muscles.
Elite SII TENS/EMS device
Multifunctional device with 100 programs. In addition to EMS (muscle stimulation) it also features TENS (pain relief). If you need pain relief alongside varicose complaints, this is the better choice.
Compression therapy unit (lymphatic massage machine, pneumatic compression, IPC)
The lymphatic massage machine works with air-chamber cuffs. The device sequentially inflates and deflates the air chambers, thereby "massaging" the leg from bottom to top — promoting venous and lymphatic return.
This method is particularly recommended for:
- more severe varicose complaints (CEAP C3–C4) and significant leg swelling;
- residual conditions after previous thrombosis (post-thrombotic syndrome) — detailed protocol in the thrombosis pillar PTS section.
Power Q-1000 Plus lymphatic massage machine
Entry-level home device. Ideal for mild to moderate varicose complaints at an affordable price.
Power Q-2200 lymphatic massage machine
Mid-range device with multiple treatment programs. Recommended for more severe complaints and frequently recurring edema.
Power Q-1000 Premium lymphatic massage machine
Advanced home device with more programs and greater comfort — for more severe (CEAP C3–C4) chronic venous insufficiency.
The full Power Q range, device selection guide and technical specifications can be found on the lymphatic massage machine category.
Before you start treatment – contraindications
To ensure safe use, know the contraindications.
When NOT to use a muscle stimulator?
- Implanted pacemaker or defibrillator
- Suspicion of active thrombosis
- Infected or inflamed skin in the treatment area
- Malignant tumor in the treatment area
- Pregnancy (abdomen and lower back)
When NOT to use the lymphatic massage machine?
- Acute deep vein thrombosis
- Severe, decompensated heart failure
- Acute skin infection, eczema or open wound on the treatment area
- Active malignant tumor in the treatment area without physician approval
Important information
In heart disease or high blood pressure use lower pressures (max. 40–50 mmHg) and shorter sessions. If unsure, consult your treating physician. Always read the device user manual before starting treatment.
Possible side effects
Treatments are generally well tolerated. Possible effects include:
- mild redness of the treated area (temporary);
- muscle fatigue after muscle stimulation;
- mild discomfort during compression.
Practical advice – what to expect from treatment?
Important to understand: established varicose veins will not regain their original shape. What you can achieve with consistent home treatment:
- relief of symptoms (pain, swelling, heavy legs);
- slowing disease progression;
- prevention of complications.
Varicose vein surgeries (sclerotherapy, laser surgery, stripping) actually mean removing or closing the problematic vein — but if your lifestyle doesn’t change, another vein may dilate in its place. Surgery should be considered when disease severity (e.g., recurrent thromboses, non-healing ulcers) leaves no other option.
My advice on creams and medicines
Many creams and medicines are marketed for varicose veins. Alone they cannot eliminate varicose dilation. Horse chestnut-containing products may relieve symptoms, but meaningful effects are achieved only together with exercise and compression therapy.
Scientific background
Structured exercise improves muscle-pump function
Padberg and colleagues showed in a randomized trial (2004) that a 6-month structured exercise program produced significant improvement in calf muscle pump function in chronic venous insufficiency.1
Hemodynamic effects of pneumatic compression
Kakkos and colleagues (2001) demonstrated that intermittent pneumatic compression can favorably influence venous circulation and relieve symptoms of chronic venous insufficiency.2
Cochrane review on the role of physical activity
The Cochrane review by Araujo and colleagues (2016) examines the role of structured physical activity in the treatment of non-ulcerated chronic venous insufficiency.3
European compression consensus (2022)
The consensus recommendation by Rabe and colleagues (2022) defines suggested compression strength by CEAP stage: from C2 20–30 mmHg, while 15–20 mmHg may be suitable for asymptomatic preventive use.4
ESVS 2022 European practice guidelines
De Maeseneer and colleagues edited the European Society for Vascular Surgery (ESVS) 2022 clinical practice guidelines on the management of chronic venous disease of the lower limbs, which represent the current standard for CEAP classification and treatment algorithms.5

Frequently asked questions
In the early stages (C0–C1) lifestyle changes and compression can significantly improve symptoms and slow progression. Once tortuous dilated veins have formed (from C2) they will not regain their original shape on their own — treatment aims to relieve symptoms and prevent complications.
Varicose vein disease is a chronic condition of vein dilation and valve insufficiency causing blood stasis. Thrombosis, by contrast, is an acute condition: a blood clot forms in the vein. Varicose veins can increase thrombosis risk (venous stasis), but they are distinct conditions. Details in the thrombosis article.
Yes, in chronic venous insufficiency (CEAP C3 and above) pneumatic compression can favorably affect symptoms (Kakkos 2001). It is contraindicated with suspected acute thrombosis. Detailed device selection: lymphatic massage machine category – varicose section.
Clinical evidence supports 30–40 minutes per day of moderate-intensity activity (walking, cycling, swimming) to improve muscle-pump function and relieve symptoms. Padberg’s 2004 randomized trial confirmed effectiveness with a 6-month structured program. With sedentary work, stand up for 2–3 minutes each hour and move your calf.
For asymptomatic preventive use the Rabe 2022 consensus recommends 15–20 mmHg. If you have symptomatic varicose disease from CEAP C2 upward, your vascular surgeon/angiologist may prescribe 20–30 mmHg or stronger stockings — use these on specialist advice.
