After Sclerotherapy: A Realistic Recovery and Compression Timeline

Last reviewed: June 12, 2026 · Compression Socks Canada Team

Sclerotherapy is one of the most common procedures for spider veins and small varicose veins in Canada. It involves injecting a solution directly into the affected veins, which irritates the vein lining, causes it to collapse, and eventually leads the body to reabsorb the treated vessel. Compression stockings play an important practical role in the days and weeks that follow. This article walks through what most Canadians can expect after a sclerotherapy session and how compression typically fits in. It is general information based on common practice and not a substitute for the specific instructions given by your treating clinician. Always follow your provider's protocol if it differs from anything here.

What sclerotherapy does

Sclerotherapy uses a sclerosant — typically a liquid or foamed solution — to deliberately damage the inner lining of a target vein. The vein collapses and the blood that previously flowed through it is rerouted into healthier vessels. The treated vein is broken down by the body over weeks to months. Sclerotherapy is most often used for:

  • Spider veins (telangiectasias) on the legs.
  • Reticular veins (the blue-green feeder veins that often sit beneath the spider veins).
  • Smaller varicose veins.

For larger truncal varicose veins, vascular specialists often recommend endovenous thermal ablation or other procedures instead. The Mayo Clinic describes the general procedure and common indications.

Why compression matters after sclerotherapy

Once a vein is treated, the goal is to keep its walls in contact while the body remodels and reabsorbs it. External graduated compression supports that process and is widely used because it can:

  • Help the treated vein walls stay closed against each other.
  • Reduce post-procedure swelling and bruising.
  • Lower the risk of trapped blood (which can darken the skin until reabsorbed).
  • Improve comfort during the days when activity may feel different.

Specific compression protocols vary by clinic. Some providers recommend 24-hour wear for a short period followed by daytime-only wear for a longer period. Others use daytime-only wear throughout. Pressure class is typically 20-30 mmHg, with 15-20 mmHg sometimes used for milder cases or for the later portion of recovery.

A typical recovery timeline

The exact pattern depends on your provider, the area treated, and your individual response. The breakdown below is a common framing.

The day of the procedure

Most patients walk out of the clinic immediately after sclerotherapy. The treated areas may feel slightly tender and may have small marks where the injections were made. Compression is usually put on immediately and worn home. Many clinicians advise a brisk walk shortly after the procedure, since calf-pump activity supports venous flow and reduces the risk of complications.

Days 1 to 3

Bruising and mild tenderness around the treated veins is common. Some providers ask you to wear stockings 24 hours a day during this period; others use daytime-only wear from the beginning. You can usually shower as instructed, gently dry the legs, and put compression back on. Avoid hot baths, hot tubs, and saunas during this window.

Days 4 to 7

You should be back to most usual activities by now, including walking and light exercise. Strenuous lower-body exercise (heavy squats, sprinting, plyometrics) is usually delayed for at least one to two weeks. Compression continues during waking hours. Some areas may still look worse before they look better, especially if trapped blood is being reabsorbed.

Weeks 2 to 4

Daytime compression usually continues for two to four weeks, although this varies. Bruising typically resolves. Mild brown or grey marks may remain along the treated veins; these usually fade over weeks to months.

Weeks 4 to 12

The full cosmetic result tends to take weeks to months to emerge as the body reabsorbs the treated vessel. Some patients need additional sclerotherapy sessions for complete clearance, especially for dense networks of spider veins. Continuing compression during the day for several weeks is a common recommendation even after the visible results have stabilised.

What to choose for post-sclerotherapy compression

Most patients use:

For spider-vein-focused patients, the spider veins collection is curated for this exact situation. Authorized Canadian brands include Sigvaris and JOBST, both of which carry products specifically marketed for post-procedural support.

Donning and care during recovery

Putting compression stockings on after sclerotherapy can feel awkward at first because the legs may be tender. Tips that help:

  • Put them on first thing in the morning when the leg is at its smallest.
  • Use a donning aid if needed (frames or slip-on devices reduce friction on tender skin). Browse easy-on options.
  • Wear cotton gloves to grip the fabric and avoid digging into the skin with fingernails.
  • Inspect the skin morning and evening. Call your clinic if you see new redness, warmth, or rapidly spreading skin changes.
  • Wash according to manufacturer instructions; most are machine washable on a gentle cycle and air dry best.

Activities to plan around

Specific guidance varies, but the following are widely seen in post-sclerotherapy instructions:

  • Walking: encouraged from day one.
  • Hot water exposure: avoided for one to two weeks (hot tubs, saunas, hot baths).
  • Sun exposure on treated areas: minimised to reduce the risk of long-term pigmentation.
  • Air travel: short flights are usually fine after a few days; longer flights often align with continued compression anyway.
  • Heavy exercise: usually delayed for one to two weeks.

When to call your clinic

Most sclerotherapy recoveries are uneventful. Call your provider promptly if you notice:

  • Significant calf pain, warmth, or swelling on one side (possible DVT).
  • Shortness of breath or chest pain (which can suggest a pulmonary embolism and is an emergency).
  • Skin ulceration or signs of skin infection near a treatment site.
  • Severe or worsening pain that does not improve.

These are uncommon but important events to flag early.

Putting it together

Compression stockings turn what could be a fragile post-procedure period into something predictable and comfortable. The specifics — 24-hour vs daytime-only wear, pressure class, total duration — depend on your provider, but the underlying logic is consistent: keep the treated veins compressed, support healthy venous return, and reduce bruising and swelling so the cosmetic and clinical result has the best possible foundation. A 20-30 mmHg knee-high stocking from an authorized Canadian retailer is the most common starting point and works well alongside the rest of your provider's post-procedure plan.

Frequently asked questions

How long do I have to wear compression after sclerotherapy?

It depends on your provider. Two to four weeks of daytime wear is common, sometimes with an initial 24-hour period in the first few days.

Can I shower right away?

Most providers allow showering soon after the procedure with specific timing. Hot baths and hot tubs are usually avoided for one to two weeks.

Will compression prevent me from getting new spider veins?

Compression supports recovery and can help with general venous health, but it does not guarantee that new spider veins will not appear. Genetics, hormones, and lifestyle factors play a role.

Should I wear compression at night during recovery?

Some providers ask for 24-hour wear during the first few days; most return to daytime-only wear after that. Follow your provider's specific protocol.

Can I exercise after sclerotherapy?

Walking is usually encouraged immediately. Strenuous lower-body exercise is typically delayed for one to two weeks.
