What to Know About Sclerotherapy: Your Complete Guide

What is Sclerotherapy?
Sclerotherapy is a widely used vein treatment designed to eliminate spider veins and varicose veins, improving both vascular health and skin appearance. This minimally invasive procedure involves injecting a specialised sclerosing solution directly into the affected veins. The solution irritates the vein walls, causing them to collapse and seal shut. Over time, the treated veins are naturally absorbed by the body, leading to smoother, clearer skin and improved circulation.
Many people choose sclerotherapy not only for cosmetic reasons but also to relieve discomfort associated with varicose veins, such as aching, swelling, and cramping. Unlike more invasive surgical options, sclerotherapy is a quick, outpatient procedure that requires little to no downtime, allowing patients to resume normal activities almost immediately. It is considered one of the most effective and reliable vein treatments, offering long-lasting results with minimal side effects. Whether seeking to enhance aesthetic appearance or improve vein health, sclerotherapy remains a trusted solution for addressing unsightly or problematic veins.
Benefits of Sclerotherapy
One of the key sclerotherapy benefits is its minimally invasive nature, making it a preferred option for those looking to treat spider veins and varicose veins without the need for surgery. Unlike more invasive procedures, sclerotherapy is performed in a clinic setting and typically takes less than an hour, with little to no discomfort. Most patients can return to their daily activities almost immediately, making it an ideal spider veins treatment for those with busy lifestyles.
Another major advantage of sclerotherapy is its ability to enhance the appearance of the treated area. By eliminating unsightly veins, the procedure helps restore smooth, clear skin, boosting confidence and comfort. Additionally, sclerotherapy can improve circulation, reducing symptoms such as swelling, aching, and cramping often associated with varicose veins. With a high success rate and long-lasting results, it is widely recognised as one of the most effective treatments for vein-related concerns.
For those in Newry and Northern Ireland, sclerotherapy benefits extend beyond aesthetics. Access to specialist vein treatments in the region means patients can receive high-quality care without the need to travel far. Newry Private Clinic offer professional consultations and tailored treatment plans, ensuring the best possible outcomes for individuals looking to improve their vascular health and skin appearance.
How Does the Sclerotherapy Procedure Work?
The sclerotherapy procedure is a straightforward and minimally invasive treatment designed to effectively eliminate spider veins and varicose veins. If you're considering this treatment, knowing what to expect can help you feel more confident about the process.
Sclerotherapy Consultation and Preparation
Before undergoing the sclerotherapy procedure, patients will have an initial consultation with a vein specialist. During this appointment, the doctor will assess the affected veins, discuss medical history, and determine if sclerotherapy is the most suitable treatment. Patients may be advised to avoid certain medications or skincare products before the procedure to ensure the best possible results.
The Injection Procedure
On the day of the procedure, patients can expect a quick and well-tolerated treatment that typically lasts between 30 to 45 minutes. The specialist will cleanse the treatment area before using a fine needle to inject a specialised sclerosing solution directly into the targeted veins. This solution causes the vein walls to collapse, sealing them shut. Over time, the body naturally absorbs the closed veins, making them fade from view. The number of injections varies depending on the size and extent of the spider veins or varicose veins being treated.
Sclerotherapy Post-Treatment Care and Recovery
Following the sclerotherapy procedure, patients can resume normal activities almost immediately, as no downtime is required. However, certain post-treatment care measures should be followed for optimal results. These may include wearing compression stockings to support healing, avoiding strenuous exercise for a few days, and keeping the treated area out of direct sunlight. Mild redness, swelling, or itching at the injection site is normal but typically resolves within a few days.
Most patients notice visible improvements within a few weeks, with continued fading over the following months. For those wondering what to expect, the sclerotherapy procedure is considered a safe and effective way to achieve clearer, healthier-looking skin while improving overall vascular health.
Is Sclerotherapy Painful?
A common concern for many considering treatment is, "Is sclerotherapy painful?" The good news is that sclerotherapy is generally well-tolerated, with most patients experiencing only mild discomfort during the procedure. Since it is a minimally invasive treatment, it does not require surgery or extensive recovery time, making it a preferred option for those seeking relief from spider veins and varicose veins.
Pain Levels During the Sclerotherapy Procedure
The sclerotherapy procedure involves injecting a sclerosing solution into the targeted veins using a very fine needle. Some patients report a slight stinging or burning sensation when the solution enters the vein, but this discomfort is typically brief and subsides quickly. Unlike surgical vein treatments, sclerotherapy does not require general anaesthesia, and most people find the procedure highly tolerable.
Pain Management During Sclerotherapy
To further minimise discomfort, specialists use several pain management techniques during sclerotherapy:
Cold compresses – Applying a cool pack before or after the injection can help numb the area and reduce any initial sting.
Local anaesthesia – In some cases, a topical numbing cream may be applied to sensitive areas before the procedure to enhance comfort.
Fine-gauge needles – The use of ultra-thin needles ensures that injections cause minimal discomfort, making the experience as smooth as possible.
Compression stockings – Wearing compression garments post-treatment helps to reduce swelling and prevent any lingering soreness.
Sclerotherapy Post-Treatment Sensations
After the procedure, it is normal to experience mild tenderness, slight swelling, or a tight sensation in the treated veins. These effects are temporary and usually resolve within a few days. Over-the-counter pain relievers (excluding aspirin, which can increase bruising) may be used if necessary, but most patients find that they do not require any medication.
If you're wondering "Is sclerotherapy painful?", rest assured that it is a low-pain, high-benefit procedure with only minimal discomfort. Thanks to modern pain management during sclerotherapy, patients can achieve clearer, healthier veins with ease and confidence.
Sclerotherapy Recovery and Aftercare
Understanding recovery after sclerotherapy is essential for achieving the best possible results. While sclerotherapy is a minimally invasive procedure with little downtime, proper post-treatment care plays a crucial role in ensuring smooth healing and long-lasting vein improvement. Most patients can return to their daily activities immediately, but following aftercare recommendations will help enhance results and minimise potential side effects.
What to Expect After Sclerotherapy
After the procedure, the treated veins will gradually fade over the following weeks and months as the body absorbs them. It is common to experience mild redness, bruising, or slight swelling around the injection sites, but these effects are temporary and usually resolve within a few days. Some patients may feel a tightness or firmness in the treated veins, which is a normal part of the healing process.
Sclerotherapy Post-Treatment Care Tips
To optimise recovery after sclerotherapy, it is important to follow these key aftercare steps:
Wear Compression Stockings – Compression garments should be worn for several days to a few weeks, as advised by your specialist. They help improve circulation, support the treated veins, and reduce swelling.
Stay Active, But Avoid Strenuous Exercise – Light walking is encouraged immediately after treatment to promote blood flow and prevent complications. However, avoid high-impact activities such as running, weightlifting, or intense workouts for at least one to two weeks.
Avoid Prolonged Standing or Sitting – Try to move regularly throughout the day to support proper circulation and healing.
Protect Your Skin from the Sun – Direct sun exposure on the treated area can cause hyperpigmentation or prolonged bruising. It is recommended to use sunscreen or keep the area covered for a few weeks after treatment.
Follow-Up Appointments – Attending scheduled follow-ups allows your specialist to monitor progress and determine if additional sessions are needed for optimal results. Some patients require multiple treatments for complete vein clearance.
By carefully following these post-treatment care guidelines, patients can maximise the effectiveness of sclerotherapy and achieve clearer, healthier-looking skin. While noticeable improvement is often seen within a few weeks, final results can take a few months to fully develop. With proper recovery after sclerotherapy, patients can enjoy long-term benefits and improved vein health.

Sclerotherapy Risks and Side Effects
While sclerotherapy is a safe and minimally invasive procedure, it is important to understand the potential risks of sclerotherapy and how to manage any sclerotherapy side effects effectively. Most patients experience only mild and temporary side effects, but being aware of what to expect can help ensure a smooth recovery.
Common Sclerotherapy Side Effects
After sclerotherapy, some patients may notice temporary changes in the treated area, which typically resolve on their own. These can include:
Bruising and Discolouration – Mild bruising at the injection sites is common and usually fades within a couple of weeks. Some patients may also notice slight brownish pigmentation, which can persist for a few months before fading.
Swelling and Redness – Mild swelling or redness around the treated veins may occur, especially in the first few days after the procedure. Wearing compression stockings can help reduce this.
Itching or Tenderness – Some patients experience minor itching or discomfort at the injection sites, which typically subsides within a few days.
Rare but Possible Risks of Sclerotherapy
Although complications are uncommon, certain risks may occur in rare cases:
Blood Clots – In very rare instances, a small blood clot may form in a treated vein. If a vein becomes firm, tender, or swollen, it is important to contact your doctor for assessment.
Allergic Reactions – Though uncommon, some individuals may have a mild allergic reaction to the sclerosing solution. If you experience sudden swelling, breathing difficulties, or a rash, seek medical attention immediately.
Matting (Small Red Vessels) – Some patients may develop tiny red blood vessels (matting) near the treated area, but these often disappear on their own or can be treated with additional sessions.
When to Seek Medical Advice
While most sclerotherapy side effects are mild and temporary, contact your specialist if you experience:
Severe pain or swelling that does not improve
A red, warm, or hard lump near the treated area
Unusual skin discolouration that worsens over time
Shortness of breath or chest pain (extremely rare, but requires immediate medical attention)
Following proper post-treatment care and attending follow-up appointments can help minimise the risks of sclerotherapy and ensure a safe, effective recovery. Most patients enjoy long-lasting results with minimal side effects, making sclerotherapy a trusted choice for improving vein health.
