Varicose veins are enlarged, twisted veins that can cause discomfort and affect how the legs look. Sclerotherapy is a common, minimally invasive treatment that helps close these problem veins. It’s often considered one of the best options because it is quick, effective, and usually involves little downtime.
Sclerotherapy is a minimally invasive, in-office treatment that targets varicose and spider veins by injecting a solution that causes them to close and gradually fade. The procedure is quick, requires little downtime, and can relieve symptoms like aching and swelling. Most patients resume normal activities the same day. APEX Vascular offers expert, convenient sclerotherapy care for patients throughout East Tennessee.
What Is Sclerotherapy?
Sclerotherapy is an outpatient treatment done in a doctor’s office to help improve problem veins. Because it is simple and minimally invasive, many patients choose it as a convenient way to reduce visible veins and related symptoms.
During the procedure, a clinician injects a special solution directly into the affected vein. This solution irritates the vein wall, causing the vein to close, collapse, and gradually turn into scar tissue that the body absorbs over time.
The procedure is commonly used to treat varicose veins and spider veins, especially smaller veins in the legs. It usually doesn’t take that long, and most people can return to normal activities soon after.
How the Procedure Works

During your appointment, your doctor will usually have you lie down and elevate your legs so that the vein is easier to access. Your skin is then cleaned and a clinician uses a very fine needle to inject the treatment solution into the affected vein.
The solution irritates the vein lining, which makes the vein swell shut and stop carrying blood. Over time, blood is naturally rerouted to healthier veins nearby.
Sclerotherapy often takes less than an hour and is typically completed in the doctor’s office. In some cases, imaging may be used to help identify the vein more precisely before treatment begins. Afterward, the treated vein gradually breaks down, is absorbed by the body, and fades from view.
Benefits of Treatment
Sclerotherapy is popular because it offers a simple, minimally invasive way to treat problem veins with little to no downtime. Many patients choose it because the procedure:
- Is efficient
- Can be done in a medical office
- Does not require surgery or a long recovery
It can improve the appearance of visible veins while also helping reduce symptoms such as aching, burning, swelling, and cramping. That makes it appealing for both cosmetic and medical reasons. The treatment is especially effective for smaller varicose veins and spider veins, particularly those in the legs.
For patients who want to address vein concerns without undergoing a surgical procedure, sclerotherapy is often a strong option. The treatment’s combination of convenience, comfort, and visible results is a major reason it remains one of the most commonly recommended vein therapies.

Recovery and Aftercare
Recovery after sclerotherapy is usually straightforward, and most patients can return to normal activities soon after treatment. Overall, recovery is usually simple, with minimal interruption to daily life and gradual improvement over the following weeks. The treated area may feel mildly tender or look slightly red or bruised at first, but this typically improves over time.
To support healing, you will be instructed to wear compression stockings or bandages for a period after the procedure. These help reduce swelling and keep pressure on the treated veins as they close. Walking is also an important part of aftercare, since staying active encourages healthy circulation and supports recovery.
In most cases, patients can go back to work, errands, and light daily routines the same day or shortly after treatment. Depending on your provider’s instructions, you may also be advised to avoid sun exposure on treated areas while the skin is healing.
Results and Expectations
You will likely begin noticing results within a few weeks after sclerotherapy, although larger veins may take longer to fully fade. In some cases, the treated vein area improves gradually over time rather than all at once.
Because every vein is different, some may need more than one session to achieve the best outcome. That is especially common when multiple veins are being treated or when the veins are larger or more stubborn.
Once treated, the veins usually collapse, fade, and do not return. However, new varicose or spider veins can still develop over time, which is why ongoing vein care may be helpful for some patients.
