Internal varicose veins: signs, risks and natural support

IMPORTANT: Internal varicose veins, especially when affecting deep veins, are a condition that can lead to serious complications such as deep vein thrombosis and pulmonary embolism. Diagnosis is made only by a phlebologist or vascular surgeon, based on clinical examination and venous Doppler ultrasound. There is no herb, tea, or natural cream that cures internal varicose veins. Everything that follows is strictly an adjunct and does not replace investigations, medical treatment, compression stockings, or minimally invasive procedures recommended by a doctor.

Internal varicose veins are one of those problems that hide from our eyes. You do not see them in the mirror like the swollen veins on the calves, but you feel them in your body: heavy legs by evening, night cramps, fatigue that does not fade even after a full night of sleep. Many people live for years with discomfort without knowing that their deep veins, those hidden between the muscles, are dilated and no longer return blood properly to the heart.

The big difference between superficial and internal varicose veins is visibility. Classic varicose veins, known to everyone, are those bluish, winding cords on the calf and thigh. Internal varicose veins are a problem of the deep veins, the large conduits that carry most of the venous blood. When they dilate, the valve system no longer closes properly, blood refluxes, stagnates, and puts pressure on the entire leg.

The good news is they can be kept under control. As a patient, you do not have many miraculous options, but you do have a very good one: the phlebologist, who knows what investigations to perform and what treatment to recommend. In addition, lifestyle and a few simple habits can do enormously well for daily comfort.

What internal varicose veins are

The venous system of the leg has two networks, linked together. The superficial network lies beneath the skin, and the deep network consists of large veins running between the muscles, alongside the arteries. Between them run connecting veins, called perforating veins, fitted with valves that push blood in only one direction, from the superficial into the deep system.

When these valves fail, or when the walls of the deep veins dilate, venous reflux appears. Blood no longer rises smoothly toward the heart but falls back, stagnates, and pressure builds up. That, in simple terms, is what internal varicose veins mean. Doctors call this chronic venous insufficiency of the deep system.

How they differ from superficial varicose veins

• They are not visible on the skin
• They affect much larger veins
• They carry a higher risk of thrombosis
• Classic surgery such as stripping does not apply here
• Different therapeutic methods are needed, sometimes endovascular

A patient may have both visible skin varicose veins and internal ones. The two problems usually overlap, because superficial insufficiency puts pressure on the deep system and vice versa.

How they form and why

The venous system works against gravity. Blood has to be pushed from the foot up to the heart, nearly a meter and a half, upward. So that blood does not fall back, veins have valves that close after each muscle contraction. The calf muscles, contracting during walking, squeeze the veins and pump the blood, while the valves close to hold it up. This mechanism is called the muscle-venous pump.

If valves weaken or break, the pump no longer works properly. Vein pressure rises, walls dilate, and veins become tortuous. The process is slow, taking many years, but once it has begun, it will not reverse without treatment.

Main risk factors

• Genetic inheritance, the strongest factor
• Being female, especially after repeated pregnancies
• Age, as vein walls lose elasticity
• Prolonged standing at work
• Prolonged sitting without movement
• Obesity, which increases intra-abdominal pressure
• Pregnancy, through hormonal and mechanical effects
• A sedentary lifestyle, not walking enough
• Chronic constipation, which forces the abdominal press
• Smoking, which affects vein walls

The more boxes you tick, the faster the problem appears. But not all people with risk factors develop internal varicose veins. Some have very resistant veins. Others, without being exposed, still develop them simply from genetic reasons.

Signs and symptoms

The signs of internal varicose veins are often mistaken for ordinary tiredness. Patients say their legs feel tired by evening, they sleep badly because of cramps, and their tight shoes bother them more than they should. Over time, symptoms worsen and become hard to ignore.

Common signs

• Heavy leg feeling, especially at the end of the day
• Ankle swelling by evening, which disappears in the morning
• Night cramps, especially in the calf
• Tingling, numbness, a burning sensation
• Dull, diffuse pain that is hard to localize
• Itching on the calf or ankle
• Brown skin pigmentation in advanced stages
• Restless legs syndrome sometimes associated
• Symptoms worsen with heat, improve with cold

Warning signs

Certain situations must bring a patient to the doctor immediately. A calf that swells suddenly, within a few hours, that is tender to touch, warm, and red, may indicate deep vein thrombosis. This is an emergency. Likewise, chest pain with shortness of breath in someone with venous problems may mean a pulmonary embolism. No hesitation, no delay, straight to the emergency room.

Diagnosis: Doppler ultrasound

The basic investigation in venous diseases is the venous Doppler ultrasound of the lower limbs. It is noninvasive, painless, and lasts 20 to 40 minutes. The doctor examines each venous segment, measures diameter, checks for reflux, and looks for thrombi.

The ultrasound is performed in the standing position, because this is when vein pressure is evaluated correctly. A scan done lying down does not give the same information. This is why it is important to consult a physician experienced in venous pathology.

Other possible investigations

• Phlebography, rarely used today
• Venous MRI in complex cases
• Venous CT with contrast substance
• Blood tests for clotting disorders

Depending on the case, the doctor may request these additional investigations. Usually a Doppler ultrasound is sufficient.

Available medical treatments

There is no miracle treatment for internal varicose veins. There is an entire arsenal, which the doctor adapts to each patient.

Conservative measures

• Medical compression (graduated stockings)
• Oral venotonics such as diosmin, hesperidin, and escin
• Adequate hydration
• Weight loss, if there are extra kilograms
• Regular movement: walking, swimming

Minimally invasive procedures

• Foam sclerotherapy for smaller veins
• Radiofrequency ablation
• Endovenous laser ablation
• Acrylic glue (VenaSeal) for certain cases

These procedures are done on an outpatient basis, with local anesthesia, and the patient goes home the same day. Recovery is quick, with activity resumed within days.

Classic surgery

Stripping, the older operation, is still practiced for certain veins. For the deep system proper, surgery is reserved for severe situations.

Compression stockings

Medical stockings, with graduated compression, are the most useful tool a patient with internal varicose veins has. They are not the same as ordinary stockings. Compression is higher at the ankle and decreases gradually toward the thigh, helping blood rise upward. There are compression classes, from I to IV. The doctor recommends the appropriate class.

Rules for use

• Put on in the morning before getting out of bed
• Remove in the evening before sleep
• Wash by hand with mild detergent
• Replace every 6 months as elasticity is lost
• Choose the correct size, measured by a pharmacist or specialist

The stocking does not cure varicose veins, but it prevents worsening, reduces swelling, and lowers the thrombosis risk. Those who think it looks unattractive forget that untreated disease leads to brown skin and ulcers, which look far worse.

Natural adjunctive support

Alongside medical treatment, there are herbs and habits that help venous circulation. Note, they do not cure, only support.

Herbs with venotonic effect

• Horse chestnut (Aesculus hippocastanum), the best known, containing escin, which reduces capillary permeability
• Butcher’s broom (Ruscus aculeatus), used in European medicine for weak veins
• Bilberry (Vaccinium myrtillus), rich in anthocyanins protecting vessel walls
• Red vine leaf (Vitis vinifera), with flavonoids supporting microcirculation
• Gotu kola (Centella asiatica), traditionally used for venous insufficiency
• Witch hazel (Hamamelis virginiana), useful topically as gel or water

These herbs come as capsules, extracts, or creams. Do not use them without consulting your doctor, especially if you take anticoagulants or other medications.

Compresses and external applications

• Cold compresses with red vine leaf decoction
• Witch hazel gel applied on the calf at night
• Massage oil with a few drops of cypress, lavender, and lemon
• Cold foot baths with sea salt

Massage should always go from bottom upward, never the other way. Never massage directly over a visible, inflamed, or painful vein.

Diet and movement

Venous circulation responds very well to lifestyle. Two things matter a great deal: what you eat and how much you move.

Vein-friendly foods

• Red and purple fruits (blueberries, blackberries, currants, dark grapes)
• Citrus, for vitamin C and flavonoids
• Leafy green vegetables, for magnesium and vitamin K
• Fatty fish, for omega 3
• Seeds and nuts
• Legumes, for fiber
• Garlic and onion, which help blood flow

To avoid or limit

• Excess salt, which retains water
• Sugar and ultra-processed foods
• Trans fats
• Large amounts of alcohol
• Very spicy foods, which increase superficial vasodilation

Daily movement

Walking is the best medicine for veins. Thirty minutes of brisk walking a day activates the muscle pump, pushes venous blood upward, and improves vein wall tone. Swimming is even better, because water pressure helps veins.

To avoid: prolonged standing without movement, squatting, heavy weightlifting with breath holding.

Practical tips

• Raise the foot of the bed by 10 to 15 cm so your legs rest slightly elevated
• Do 5 minutes of ankle circles every hour if you sit at a desk
• Avoid very hot baths and prolonged sauna
• Wear comfortable shoes, avoiding daily high heels
• Drink at least 2 liters of water per day
• Do not cross your legs for hours
• Do 50 tiptoe raises each morning
• Wear compression stockings during flights longer than 4 hours
• See your phlebologist every 1 to 2 years, even without new symptoms

Frequently asked questions

Can internal varicose veins be cured with teas? No. Teas and herbs are only adjuncts. Once formed, internal varicose veins do not return to their original state without medical treatment. What natural means can do is slow progression and ease symptoms.

Are compression stockings to be worn in summer? Yes, especially in summer, because high temperature worsens symptoms. There are thin, breathable models designed for the warm season.

Is sport dangerous if I have internal varicose veins? On the contrary, it is recommended, with a few exceptions. Avoid high-impact sports and heavy weightlifting. Walking, swimming, cycling, and light gymnastics are advised.

Can I get lymphatic drainage massage? Yes, if performed by a qualified therapist and after the doctor has ruled out thrombosis. Never on a warm, red, painful calf.

Do varicose veins disappear after pregnancy? Partially, yes. Those appearing during pregnancy from hormonal and mechanical causes may regress after birth. But with genetic predisposition and multiple pregnancies, they may remain or return.

Is surgery necessary for all internal varicose veins? No. Many cases are controlled very well with compression and medication. The decision for surgery belongs to the doctor, not the patient.

What should I get from the pharmacy for varicose veins? There is no single answer. It depends on what the doctor recommends after consulting you. Do not start venotonic treatment on your own, especially while taking other medications.

Internal varicose veins are a chronic but manageable disease. If you act in time, listen to your doctor, and pay attention to lifestyle, you can lead a normal life without complications. The secret is not a miracle herb but discipline: stockings in the morning, daily movement, regular check-ups. And if you have any doubts, ask the phlebologist, not the internet forums.
