Sclerotherapy is commonly used to treat spider veins and smaller varicose veins. During treatment, a solution is injected into the affected vein, causing it to close so blood can reroute through healthier veins. The treated vein then gradually fades over time. Recovery is relatively simple, with most patients able to resume their regular activities on the same day; however, it will take some time for the treated veins to fade away completely.
Bruising, mild swelling, tenderness, or temporary skin discoloration can happen while the area heals, and visible improvement often takes several weeks or longer. Knowing what is normal during each stage of recovery can make the process easier to understand and help you recognize when something deserves a call to your provider.
What Should You Expect After Sclerotherapy?
Immediately after treatment, your provider may ask you to walk for a short period. Walking helps keep blood moving through the legs and is commonly encouraged after sclerotherapy. Most patients can leave the office shortly after the procedure and resume many of their usual activities.
Compression stockings and bandages may also be suggested by your healthcare practitioner. How long you wear them depends on the veins treated and the type of sclerotherapy performed.
Sclerotherapy Recovery Timeline
Recovery can vary from person to person, but the following timeline gives you a general idea of what to expect as the treated veins begin to heal and fade.
The First 24 Hours
You can usually walk shortly after treatment and return home the same day. Mild stinging, tenderness, swelling, or bruising around the injection sites can occur, and the treated veins may look darker, firmer, or more noticeable before they begin to fade.
Follow your provider’s instructions regarding compression stockings, showering, medication, and physical activity. You may also be advised to avoid hot baths, saunas, whirlpools, and other direct heat for a short period after treatment.
The First Few Days
Most people can return to work and normal daily activities quickly. Light walking is usually encouraged, while strenuous exercise may need to wait depending on the veins treated and your provider’s recommendations.
Bruising, redness, mild swelling, and tenderness can still be present during this stage. Treated veins may also feel firm or lumpy as they close and begin to heal, and your provider may recommend continuing to wear compression stockings during the day.
The First 1 to 2 Weeks
By this point, most soreness and swelling should be improving, although bruising may still be visible and some veins can look darker before they fade. Strenuous exercise, heavy lifting, or high-impact activity may still need to be limited depending on the treatment performed.
Sun protection is also important because treated areas can be more prone to temporary pigmentation changes. If the treated area is exposed, follow your provider’s recommendations for sunscreen and sun avoidance.
3 to 6 Weeks
This is often when improvement becomes more noticeable, especially for spider veins and smaller veins. Treated veins will continue to fade slowly, but even after this period, some color change, hardness, or outlines of veins might still be present.
Not every vein fades at the same rate, so some areas may improve faster than others. Your provider will evaluate your results and tell you if more time is required.
3 to 4 Months
Larger treated veins can take several months to fade fully. By this stage, the final result may be easier to judge, although some patients need more than one sclerotherapy session, particularly when multiple veins or larger areas are being treated.
Your provider may recommend follow-up treatment if certain veins remain visible or if additional areas need attention.
What Is Normal After Sclerotherapy?
Several temporary changes can happen while the treated veins heal. Common effects can include:
- Mild bruising around the injection sites
- Tenderness or soreness in the treated area
- Temporary redness or mild swelling
- Firm or lumpy areas along a treated vein
- Brown or darker skin discoloration
- Small visible blood vessels near the treated area
These changes often improve gradually rather than all at once. Bruising can last for several days or weeks, while discoloration may take longer to fade. Your provider can tell you whether what you are seeing falls within the expected recovery process.
How Long Should You Wear Compression Stockings?
Compression recommendations vary, so follow your provider’s instructions rather than relying on a general timeline. The type of treatment may require wearing compression stockings or wraps for several days or even more.
Compression applies steady pressure that helps the treated veins heal properly. Wear the compression your provider recommends rather than ordinary support stockings.
Can You Walk After Sclerotherapy?
Walking is generally encouraged shortly after treatment because light movement promotes circulation and keeps blood flowing through the healthier veins. Most patients are able to walk right away and continue with normal light activity.
Long periods of complete inactivity are usually discouraged unless your provider gives you different instructions. Regular short walks can be a useful part of recovery during the first few days.
When Can You Exercise After Sclerotherapy?
Walking may be started right away, but other exercises might have to wait. When you can return to running, weight lifting, cycling, or other high-impact activity depends on the size and location of the veins treated.
Your provider can give you a more specific timeline based on your procedure and how your legs are healing. Returning to exercise gradually is often better than jumping back into a full routine too quickly.
How Long Does It Take to See Results?
There is no immediate effect seen after sclerotherapy. Spider veins and small varicose veins begin fading in a few weeks, but it may take a few months for large veins to become less visible.
Not every vein responds the same way, and some areas may need more than one treatment. If another session is recommended, your provider will usually wait long enough to see how the first treatment is healing before treating the area again.
Can Veins Look Worse Before They Look Better?
Yes. Veins that have been treated may appear darker, more pronounced, or even bruised before improving. The skin may also appear firm or discolored for a while until the vein is closed and absorbed by the body.
These changes usually improve with time. If the area becomes increasingly painful, swollen, red, or starts to look worse instead of better, contact your provider.
What Should You Avoid During Sclerotherapy Recovery?
Your exact instructions will depend on your treatment, but you may be advised to temporarily avoid strenuous exercise, hot baths, hot tubs, saunas, direct heat, and prolonged sun exposure. You may also be told to wait before shaving or applying lotion over fresh injection sites.
Medication instructions can vary as well. Do not stop aspirin, blood thinners, anti-inflammatory medication, or other prescribed medicines unless your healthcare provider specifically tells you to.
When Should You Call Your Provider?
Mild bruising and tenderness are common, but certain symptoms deserve prompt attention. Contact your provider if you develop sudden or increasing leg swelling, worsening redness, significant pain, an ulcer at an injection site, or symptoms that continue to get worse.
Seek emergency medical care for sudden shortness of breath, chest pain, dizziness, coughing up blood, or other symptoms that could indicate a pulmonary embolism. Blood clots are uncommon after sclerotherapy, but they require immediate medical attention if they occur.
Will You Need More Than One Sclerotherapy Treatment?
While some patients require only one session of treatment, others may require multiple sessions depending on the number, size, and site of the veins. Smaller spider veins may respond faster, while other vein patterns may require multiple sessions of treatment.
Your provider can review your progress at a follow-up visit and determine whether another treatment session would be helpful.
Make the Most of Your Sclerotherapy Recovery
The recovery period from sclerotherapy is typically short, but the improvement will take place gradually. Walking immediately after the procedure, following the compression advice, avoiding vigorous exercise, and caring for the treated skin area are some activities that will help your recovery process.
