When considering sclerotherapy to remove unwanted spider veins or small varicose veins, it’s completely natural to ask, “Does it hurt?” After all, the treatment involves injecting a solution directly into a vein, and that alone can cause hesitation for many patients.

At The Dermatology, Laser & Vein Center in Cincinnati, Ohio, we perform thousands of sclerotherapy treatments each year—and we’re here to assure you that the discomfort is minimal, and the procedure is far more comfortable than most people expect. In fact, the majority of patients say it’s easier than a flu shot and well worth the beautiful results.

Here’s what you need to know about the sensation and experience of sclerotherapy.

What Is Sclerotherapy?

Sclerotherapy is a non-surgical injectable treatment used to treat spider veins and small varicose veins. A solution called a sclerosant is injected into the target vein using a fine needle. This causes the vein to collapse and eventually be absorbed by the body. Over time, the treated vein fades away, and blood is rerouted through healthier vessels.

The treatment is fast, highly effective, and considered the gold standard for cosmetic vein removal.

What Does Sclerotherapy Feel Like?

Most patients describe the sensation as mild and very tolerable. Here’s what you can expect at each stage:

During the Injection

• You may feel a tiny pinprick as the needle enters the skin

• The sclerosant may cause a mild stinging or tingling sensation as it enters the vein

• In some areas, you may notice slight cramping or a warm flush

The sensation typically lasts only a few seconds per injection, and most sessions involve several quick injections over 15–30 minutes.

After the Injection

• You may feel slight pressure or tightness in the treated area

• Temporary itching or mild burning may occur at the injection site

• Treated veins may feel slightly firm or raised for a few days

Discomfort is usually minimal and resolves quickly. Most people return to their normal activities the same day.

Is Sclerotherapy Painful?

While pain tolerance varies from person to person, sclerotherapy is not considered a painful procedure. In fact, many patients say:

• “It stings a little but wasn’t bad at all.”

• “It was more like a mosquito bite than anything else.”

• “Definitely worth it for the results.”

We use ultra-fine needles and inject the solution slowly to ensure maximum comfort. If you have sensitive skin or anxiety about needles, we’ll take additional steps to help you relax during treatment.

What About Sensitive Areas?

Some areas of the body may be more sensitive than others. For example:

• Ankles and feet have thinner skin and more nerve endings

• Inner thighs and behind the knees may feel more tender

Even in these areas, discomfort is still very mild and short-lived. We always tailor your treatment to minimize sensitivity.

Can Numbing or Anesthesia Be Used?

In most cases, numbing is not necessary because the discomfort is so minimal. However, we may use:

• Cold packs to reduce sensation

• Topical numbing cream if requested

• Distraction techniques for nervous patients

Our goal is to make you as comfortable as possible throughout the process.

What About After the Procedure?

Following sclerotherapy, you may experience:

• Mild soreness or aching, especially in the evening after treatment

• Bruising or redness at the injection site

• Slight firmness or tenderness along the vein path

These are temporary and typically resolve in a few days to a few weeks. Wearing compression stockings and walking regularly helps reduce discomfort and improves results.

How Long Does the Discomfort Last?

Any discomfort from the injections usually subsides within minutes to a few hours. Post-treatment tenderness may last a few days, depending on the number of veins treated and the area of the body.
