Does Varicose Veins Need to Be Operated on If Nothing Hurts

If varicose veins do not hurt, surgery is not always necessary. The decision is based on the results of vein duplex ultrasound, the severity of reflux, the diameter of the affected trunk, the condition of the tributaries, and the CEAP stage. Sometimes the right approach is observation. This is not a refusal of treatment, but a well-founded medical decision.

A person may notice a prominent vein after a workday but feel no pain. Another patient may be troubled by heaviness and swelling even though the vascular network looks small. Appearance and pain alone cannot reliably determine who requires intervention.

Why the Absence of Pain Is Not Reassuring

Varicose vein disease is associated with impaired function of the venous valves. Blood flows not only upward toward the heart but also partially back downward. This backward flow is called reflux.

The body can compensate for this problem for a long time. Therefore, enlarged veins are not always accompanied by pain. In some patients, pronounced reflux is discovered by chance. Conversely, even minor changes can cause heaviness, a feeling of pressure, night cramps, or swelling.

Pain does not always accurately reflect the condition of the veins:

• people’s sensitivity differs;
• symptoms depend on exertion, heat, and how long a person sits or stands;
• external signs do not always correspond to the condition of the deep veins;
• unpleasant sensations may be related to causes other than the veins.

Therefore, it is important for the doctor to know about pain, but this sign alone is not enough. The function of the venous system must be assessed.

It is useful to understand separately what reflux on vein duplex ultrasound means. The presence of reflux alone does not mean that surgery is needed. The doctor assesses its location, severity, and relationship to clinical manifestations.

What Determines the Decision: Ultrasound, CEAP, and Examination

The main examination before choosing treatment is vein duplex ultrasound. It shows not only enlarged vessels but also the direction of blood flow.

I assess:

• the presence of pathological reflux;
• the venous segment where it occurs;
• its duration;
• the diameter of the main trunk;
• the condition of the tributaries;
• the patency of the deep veins;
• signs of thrombosis and other changes requiring a separate treatment approach.

A treatment plan cannot be created from a photograph of the leg or a brief description. Similar external signs may have different causes and require different treatment volumes.

The CEAP classification is also used. It describes the stage of the disease according to its clinical manifestations, cause, anatomy, and mechanism of dysfunction. In simplified form, it takes into account:

• spider veins and small reticular veins;
• enlarged varicose veins;
• swelling;
• skin changes;
• a healed or open venous ulcer.

CEAP does not replace an examination and ultrasound. But it does not allow the assessment to be reduced to the formula: 「it does not hurt, so everything is fine」.

When Surgery May Not Be Necessary

Observation may be the right decision if ultrasound does not show indications for eliminating pathological blood flow, the changes are minimal, and the condition is stable. Sometimes enlarged vessels remain primarily a cosmetic concern. In that case, correction can be discussed, or no intervention may be performed.

Surgery or minimally invasive treatment is not automatically necessary for every person with a visible vein. There is no reason to treat only an image on the skin if the examination does not confirm a significant impairment of venous outflow.

A doctor may recommend observation if:

• there is no significant reflux in the truncal veins;
• the deep veins are patent;
• there are no complications;
• symptoms are absent or have almost no impact on daily life;
• the current risk and expected benefit of intervention do not justify treatment.

Observation does not mean complete inaction. You need to understand which changes to monitor, when to repeat the examination, and in which situations to seek care sooner. The timing of follow-up ultrasound is determined individually.

If treatment is necessary, the method depends on the anatomy of the veins. In my practice, this includes EVLA with a Biolitec laser, sclerotherapy, miniphlebectomy, and other methods within their indications. CLaCS is used for spider veins: a cryolaser acts through the skin, while the sclerosant is injected into the feeding vein. The spider veins themselves are not removed through punctures. Prominent varicose tributaries are removed through small punctures. This is miniphlebectomy.

What Happens If You Simply Wait

Varicose veins usually develop slowly. Waiting for several weeks or months without warning symptoms does not mean there is an immediate danger. However, pathological reflux usually does not disappear on its own. As the condition progresses, changes in the venous wall and valves become irreversible.

Over time, the following may develop:

• an increase in the number and size of varicose veins;
• evening heaviness;
• swelling of the lower legs;
• changes in skin color and firmness;
• inflammation of a vein;
• skin damage and ulcers that are slow to heal.

This does not mean that such changes will necessarily occur in everyone. It is wrong to pressure a patient through fear. But postponing an examination simply because 「it does not hurt yet」 is also unreasonable.

The purpose of an early consultation is not necessarily to prescribe a procedure, but to assess the situation before complications develop. After that, treatment, observation, or lifestyle management can be chosen. If the problem is primarily cosmetic, the doctor should say so directly. With significant reflux, the consequences of waiting and suitable treatment options should be discussed.

Self-Check at Home and What to Do Next

A self-check does not establish a diagnosis. It helps you notice changes and prepare information for the doctor.

Today you can:

• examine both legs under the same lighting and note any prominent veins, changes in skin color, or irritation;
• compare the appearance of the legs in the morning and evening and record when a noticeable difference appeared;
• pay attention to sock marks, tightness, heaviness, or a feeling of pressure toward the end of the day;
• recall whether you experience night cramps, itching, burning, or thickening along the course of a vein;
• do not massage a painful area or try to puncture or 「drain」 a vein yourself;
• find the results of any previous ultrasound. It is important to review not only the conclusion but also the description of the venous segments and blood flow.

The next steps are:

• Schedule an in-person examination and vein duplex ultrasound if the test was performed a long time ago or your condition has changed.
• Bring previous reports, a list of medications, and information about any prior interventions.
• Ask the doctor to show on a diagram where the reflux is located and which veins are contributing to it.
• Clarify whether there are indications for treatment now or whether observation is appropriate.
• If a procedure is recommended, ask what exactly will be treated, which method will be used, what restrictions are expected afterward, and what is included in the written estimate.
• Do not compare offers based on price alone. The treatment volume and cost can be determined accurately only after ultrasound. The estimate should be provided in writing.

At the consultation, it is useful to ask:

• What is the CEAP stage?
• Is there pathological reflux, and where is it located?
• Which tributaries are involved?
• What will change if we observe?
• Which signs would be a reason to seek care sooner?
• Is observation sufficient, or are compression, symptom treatment, or a procedure needed?
• Why was this particular method chosen?

When to Seek Urgent Medical Attention

Seek urgent medical attention if you develop:

• sudden noticeable swelling of one leg;
• rapidly increasing pain or severe pressure;
• redness and a painful thickening along the course of a vein;
• bleeding from a varicose vein;
• a sudden change in the color or temperature of the foot;
• shortness of breath, chest pain, sudden weakness, or dizziness.

The cause of such symptoms cannot be determined through correspondence. Do not wait for a scheduled visit or try to treat them yourself. If a vein is bleeding, press the area with a clean tissue or bandage, lie down, raise the leg, and seek emergency medical help. I have written more about first aid in the article what to do if a varicose vein bleeds.

Myth: If It Does Not Hurt, It Does Not Need Treatment

This is a partial truth turned into a mistake. The absence of pain may support observation if ultrasound shows no significant abnormality and there are no complications. But by itself, it does not replace an examination.

The opposite mistake also occurs: a person sees a large vein and assumes it must be removed immediately. Appearance does not determine the need for or method of treatment. A prominent vein may not be the main source of reflux. Conversely, minor external signs may sometimes be accompanied by impaired blood flow that is visible only on ultrasound.

I have been practicing vascular surgery since 2019 and follow a simple principle: first confirm the problem, then discuss intervention. If there are no indications, I say so directly. If treatment is necessary, I explain which vein needs to be closed or removed and why, as well as what alternatives exist.

Practical conclusion: painless varicose veins do not automatically mean either 「operate」 or 「forget about it」. Have a vein duplex ultrasound, assess the reflux, trunk diameter, tributaries, and CEAP stage. Then choose treatment or observation together with your doctor.
