The Answer to the Most Common Questions About Varicose Veins

Have you ever noticed bulging and visible veins, aching legs, or night time restlessness? If yes, you’ve probably asked yourself, “Is this normal?” Let us break it to you “YOU ARE NOT ALONE” — varicose veins and related vein issues affect nearly 1 in 3 adults, especially as we age or spend long hours on our feet.

To help clear up the confusion, I have curated a list of some commonly asked questions by patients.

Whether you're researching for yourself or supporting a loved one, this guide is prepared to give you trustworthy, digestible answers from real experts in vein health.

What Causes Varicose Veins?

Varicose veins happen when vein valves become weak or damaged, allowing blood to pool instead of flowing efficiently back to the heart. This pooling stretches the vein walls, creating those visible, twisted veins, usually in the legs.

Risk factors include:

• Family history

• Prolonged standing or sitting

• Pregnancy

• Age (especially over 40)

• Obesity

• Sedentary lifestyle

While they're often considered cosmetic, varicose veins can lead to discomfort, swelling, skin changes, and even ulcers in more advanced cases.

Here are a few commonly asked questions on Google when it comes to Vein treatment -

1. Is Deep Vein Thrombosis (DVT) a Side Effect of Vein Ablation?

Not typically, but this is a common concern. Endovenous ablation (either with laser or radiofrequency) is a safe, FDA-approved procedure that treats varicose veins by sealing off the problematic vein.

That said, there is a very small risk of DVT, estimated at under 1%. This is why vein specialists perform a duplex ultrasound before and after treatment to monitor blood flow and rule out complications.

Always follow your doctor’s aftercare instructions, wear compression stockings if prescribed, and report symptoms like leg swelling or leg pain immediately.

2. How Can I Improve Blood Circulation in My Legs?

Circulation plays a key role in preventing and managing vein issues. Here’s what vein doctors recommend:

• Move more: Walking, swimming, or cycling are great low-impact options

• Avoid long periods of sitting or standing: Try to move or stretch every 30 minutes

• Elevate your legs: Especially after long days or workouts

• Wear compression socks: These support vein walls and improve blood return

Bonus tip: Avoid tight clothing around your thighs — it can restrict circulation.

3. What Diet Helps with Venous Insufficiency?

While food alone won’t cure vein problems, a vein-friendly diet can support healthy circulation and vessel integrity.

Try to include:

• High-fiber foods: oats, beans, whole grains

• Antioxidant-rich fruits: berries, oranges, grapes

• Leafy greens: kale, spinach, Swiss chard

• Hydrating foods: cucumbers, celery, watermelon

• Omega-3s: salmon, chia seeds, walnuts

And be sure to cut down on sodium, which can worsen swelling and water retention in the legs.

4. What Is a Venous Doppler Ultrasound?

A venous Doppler ultrasound is a non-invasive scan that uses sound waves to assess blood flow in your leg veins. It helps doctors detect:

• Valve dysfunction (often the root of varicose veins)

• Blood clots

• Venous reflux (blood flowing the wrong way)

You’ll lie on a table while a technician uses a handheld device (transducer) with some gel to examine your legs. The scan is painless, takes 30–45 minutes, and is essential for an accurate vein treatment plan.

5. Why Do My Calves Hurt from Standing All Day?

Standing for long periods puts extra pressure on the veins in your lower legs. Over time, this can lead to blood pooling, which stretches the veins and triggers pain, aching, or cramping.

If you notice this often, consider it a sign your circulation might need support. Vein doctors often recommend:

• Taking sitting breaks

• Wearing compression socks

• Doing simple calf raises throughout the day

Persistent calf pain could also indicate chronic venous insufficiency or early varicose veins — so it’s worth checking in with a specialist.

6. What Causes Leg Jerks at Night?

Nighttime leg jerks can be related to restless legs syndrome (RLS), a common but often misunderstood condition. It’s frequently seen in people with venous disease.

Other contributing factors include:

• Iron deficiency

• Poor circulation

• Nerve damage

• Medications or caffeine

If you're noticing twitching, tingling, or a strong urge to move your legs at night, talk to a doctor. Vein health and RLS are often linked, especially in people over 40 or those with sedentary jobs.

7. Do Varicose Veins Go Away on Their Own?

Unfortunately, no. Varicose veins tend to worsen over time without intervention. While lifestyle changes can help manage symptoms, medical treatment is often the only way to fully eliminate the damaged vein.

8. Are Varicose Veins Dangerous?

Not usually — but they can be. If left untreated, they can lead to:

• Skin ulcers

• Chronic swelling

• Superficial thrombophlebitis (vein inflammation)

• Blood clots

If you're unsure whether your symptoms are serious, it’s always best to get a vein screening.

Signs it’s time to book a consultation:

• Leg heaviness or aching that worsens by day's end

• Swelling around ankles

• Visible twisted veins

• Skin discoloration or itchiness near veins

• Nighttime restlessness

If you’re experiencing any of these, a Chicago vein specialist can help you understand your options.

Conclusion

Vein health can feel overwhelming, but it doesn’t have to be. Whether you’re just starting your research or considering treatment, the most important step is asking questions and seeking trusted answers — like you’re doing now.

If you’re in the Chicago area and dealing with symptoms of varicose veins or chronic vein discomfort, a board-certified phlebologist or vascular specialist can guide you toward relief.
