How Long Will My Leg Hurt After Vein Ablation

How Long to Expect Leg Discomfort After Vein Ablation

If you suffer from venous reflux disease and painful, achy varicose veins, your doctor may recommend a minimally invasive treatment called vein ablation. This procedure uses heat, laser energy, or chemical injections to collapse and seal off damaged veins so they can no longer pool blood and cause swelling, throbbing, and discomfort in your legs. But while vein ablation offers an effective alternative to stripping veins, it still involves inserting catheters and delivering targeted energy to your veins. Now you thinking how long will my leg hurt after vein ablation? Read on for more details on the vein ablation recovery timeline.

Vein ablation is an extremely effective procedure for treating varicose veins and relieving symptoms like leg pain or heaviness. But after years of discomfort, many patients wonder how long it will hurt after the treatment itself. While vein ablation involves a relatively quick procedure with minimal pain, some short-term achiness or soreness can occur as side effects.

The vein ablation recovery timeline for most people ranges between a few days to one week on average. But there are many helpful tips to ease any post-procedure leg discomfort. Knowing what to expect and focusing on healing techniques can speed the return to pain-free legs. The vein ablated itself may continue to be somewhat tender for a few weeks as it dies off and the body fully reabsorbs it. So give yourself plenty of time to heal and don’t overdo physical activities too soon. Along with potential pain, other natural side effects like bruising and swelling gradually subside as well. With adequate rest, the healing should progress quickly, but pay close attention to any symptoms that seem unusual or severe.

What Is Vein Ablation?

Vein ablation is a minimally invasive treatment for varicose veins and spider veins. It works by collapsing and sealing off unhealthy veins so blood reroutes to healthier veins.

During vein ablation, an interventional radiologist inserts a small catheter into the affected vein through a tiny incision. The catheter delivers either radiofrequency energy or laser energy to heat the inside of the vein. This heat damages the vein walls causing them to collapse and seal shut.

Over the next few weeks, the sealed vein is reabsorbed by the body. Blood flow is redirected to other healthy veins. The treatment takes less than an hour and does not require hospitalization or general anesthesia.

Vein ablation provides an alternative to vein stripping surgery. It is used to treat symptoms like painful, achy legs, leg heaviness, fatigue, skin damage or leg ulcers from venous insufficiency, and varicose veins that cause discomfort or distress.

The procedure shows effective long-term closure rates of over 90% for varicose veins and 80% for spider veins. After treating the dysfunctional veins, most patients experience symptom relief and improved appearance of bulging varicose veins.

Ablation Procedure Explained

To understand post-procedure pain levels, it helps first to understand what happens during vein ablation. There are a few methods used:

Radiofrequency Ablation: Using ultrasound, the doctor inserts a small catheter into the target varicose vein and heats the tip, causing the vein walls to collapse and seal shut.

Laser Ablation: Much like radiofrequency, a laser fiber catheter is inserted into the vein. Laser energy applied through the tip damages the vein so it can no longer transport blood.

Sclerotherapy: A chemical irritant (either foam or liquid) is injected directly inside the vein, causing scarring and closure of the vein’s interior lining.

All vein ablation methods are conducted under local anesthesia and feel similar to getting an IV. The procedure itself takes less than an hour depending on the number of veins treated.

What to Expect: Discomfort and Bruising

After any vein ablation procedure, you can expect the following for 1-2 weeks:

  • Tenderness, swelling and bruising along the treated vein areas. Using compression stockings helps minimize this.
  • Mild to moderate dull ache or throbbing sensation in your legs. Usually controlled by over-the-counter pain medication.
  • Hard lumps under the skin where veins were treated due to inflammation (more common with sclerotherapy). Fades over time.
  • Brown/red discoloration along treatment sites as bruised blood vessels heal.

So when can you expect leg discomfort after vein ablation to disappear? Here’s a general timeline:

Pain Levels and Duration After Vein Ablation

Day 1 – 3:

The most discomfort occurs in the first 72 hours following ablation. Swelling may increase, with moderate soreness and tenderness along treatment sites. Elevation, rest, compressions stockings and OTC medication keeps pain manageable.

Week 1:

The worst swelling and bruising occurs roughly 5 days after ablation, appearing black/blue. Aching and tenderness gradually decreases but legs may tire easily. Compression stockings are still encouraged daily.

Week 2:

Discomfort noticeably improves during the 2nd week. Bruising yellows as veins continue healing. Sore spots remain but are less tender. Light activity can be resumed like short 20-minute walks.

Week 3:

You should turn the corner pain-wise by week 3, with minimal achiness as treated veins fully seal off. Bruises turn green/brown before disappearing. Compression stockings are generally not needed unless legs feel tired.

1 Month Out:

By 4 weeks post-procedure, swelling, soreness and fatigue generally disappear in the legs. Minor tenderness may flare up after overactivity. Healed, closed veins should no longer throb or ache.

When to Call Your Doctor

While temporary leg discomfort is expected after ablation, call your doctor if you experience:

  • Uncontrolled, worsening pain not relieved by medication and elevation
  • Excessive swelling causing skin discomfort
  • Expanding redness, warmth, and tenderness (signs of infection)
  • Bleeding or fluid leaking from treatment sites
  • Leg numbness, tingling, or loss of function

Staying Comfortable During Recovery

Working with your doctor, there are several ways to manage leg discomfort after vein ablation:

  • Take prescribed pain medication or OTC options like acetaminophen or anti-inflammatories.
  • Refrain from strenuous activity for 1 week post-procedure, avoiding standing for long periods.
  • Elevate legs above heart level for 30 minutes, 2-3 times daily to minimize swelling.
  • Apply cold compresses to painful sites in 10-minute increments to reduce inflammation.
  • Wear medical compression socks offering 15-20 mmHg gradient pressure daily, helping veins and valves heal.
  • Stay hydrated drinking at least 64 oz water daily and maintain a balanced diet to support healing.

What Results to Expect After Healing

Once veins seal shut and symptoms fully subside weeks later, the long-term outcomes make tolerating short-term discomfort worthwhile. Benefits include:

  • Resolution of painful symptoms like aching, throbbing varicose veins
  • Reduced leg fatigue, heaviness and night cramps
  • Lessened appearance of ropey, bulging varicose veins
  • Decreased risk of bleeding veins, leg ulcers or blood clots

So while vein ablation involves manageable discomfort during the healing process, the long-term gains make it an effective option for resolving venous dysfunction and troublesome varicose veins.


How quickly can I resume exercise after vein ablation?

Refrain from strenuous activity for 5-7 days. After the first week, you can start light exercise like walking, swimming or stationary cycling for 20 minute sessions. Listen your body and scale back if legs feel tired or achy.

Will I need additional vein ablation procedures in the future?

It’s possible. Varicose veins stem from underlying venous dysfunction. Without lifestyle changes, this can lead to new problem veins developing over time. Your doctor determines if repeat ablation is needed for new veins.

Do veins return after ablation?

Treated veins sealed by ablation should no longer grow back or reflux blood. However, new varicose veins may eventually surface due to progressive valve damage.

When will visibility of my varicose veins improve?

While sealing veins off stops related symptoms, existing varicose veins may not change appearance much. Ask your doctor about additional sclerotherapy injections to improve visibility.

Can I travel home by plane after ablation?

Yes, but take precautions. Wear compression socks, stay hydrated, periodically stretch legs and avoid crossing them during long flights soon after ablation. Move about every 30-60 minutes.


Undergoing vein ablation provides lasting relief from painful venous reflux disease if you’re willing to endure some temporary discomfort during the healing process. While legs may ache or throb significantly in the first week post-procedure, these annoyances gradually fade by week three as treated veins fully close. Knowing what to expect for pain and recovery empowers patients to stick out this period for long-term gain. So take it easy initially, elevate legs to minimize swelling, and trust the healing timeline. In a month your legs should feel remarkably better, ready to resume normal life free of bulging varicose veins and bothersome symptoms, making ablation an extremely effective vascular treatment.
