Varicose veins are twisted, enlarged veins. Any superficial vein may become varicosed, but the veins most commonly affected are those in your legs. That's because standing and walking upright increases the pressure in the veins of your lower body.
For many people, varicose veins and spider veins — a common, mild variation of varicose veins — are simply a cosmetic concern. For other people, varicose veins can cause aching pain and discomfort. Sometimes varicose veins lead to more-serious problems.
Treatment may involve self-care measures or procedures by your doctor to close or remove veins.
Varicose veins may not cause any pain. Signs you may have varicose veins include:
- Veins that are dark purple or blue in color
- Veins that appear twisted and bulging; they are often like cords on your legs
When painful signs and symptoms occur, they may include:
- An achy or heavy feeling in your legs
- Burning, throbbing, muscle cramping and swelling in your lower legs
- Worsened pain after sitting or standing for a long time
- Itching around one or more of your veins
- Skin discoloration around a varicose vein
Spider veins are similar to varicose veins, but they're smaller. Spider veins are found closer to the skin's surface and are often red or blue.
Spider veins occur on the legs, but can also be found on the face. They vary in size and often look like a spider's web.
When to see a doctor
Self-care — such as exercise, elevating your legs or wearing compression stockings — can help you ease the pain of varicose veins and may prevent them from getting worse. But if you're concerned about how your veins look and feel and self-care measures haven't stopped your condition from getting worse, see your doctor.
Weak or damaged valves can lead to varicose veins. Arteries carry blood from your heart to the rest of your tissues, and veins return blood from the rest of your body to your heart, so the blood can be recirculated. To return blood to your heart, the veins in your legs must work against gravity.
Muscle contractions in your lower legs act as pumps, and elastic vein walls help blood return to your heart. Tiny valves in your veins open as blood flows toward your heart then close to stop blood from flowing backward. If these valves are weak or damaged, blood can flow backward and pool in the vein, causing the veins to stretch or twist.
These factors increase your risk of developing varicose veins:
- Age. The risk of varicose veins increases with age. Aging causes wear and tear on the valves in your veins that help regulate blood flow. Eventually, that wear causes the valves to allow some blood to flow back into your veins where it collects instead of flowing up to your heart.
- Sex. Women are more likely to develop the condition. Hormonal changes before your period or during pregnancy or menopause might be a factor because female hormones tend to relax vein walls. Hormone treatments, such as birth control pills, might increase your risk of varicose veins.
- Pregnancy. During pregnancy, the volume of blood in your body increases. This change supports the growing fetus, but also can produce an unfortunate side effect — enlarged veins in your legs. Hormonal changes during pregnancy may also play a role.
- Family history. If other family members had varicose veins, there's a greater chance you will too.
- Obesity. Being overweight puts added pressure on your veins.
- Standing or sitting for long periods of time. Your blood doesn't flow as well if you're in the same position for long periods.
Complications of varicose veins, although rare, can include:
- Ulcers. Painful ulcers may form on the skin near varicose veins, particularly near the ankles. A discolored spot on the skin usually begins before an ulcer forms. See your doctor immediately if you suspect you've developed an ulcer.
- Blood clots. Occasionally, veins deep within the legs become enlarged. In such cases, the affected leg may become painful and swell. Any persistent leg pain or swelling warrants medical attention because it may indicate a blood clot — a condition known medically as thrombophlebitis.
- Bleeding. Occasionally, veins very close to the skin may burst. This usually causes only minor bleeding. But any bleeding requires medical attention.
There's no way to completely prevent varicose veins. But improving your circulation and muscle tone may reduce your risk of developing varicose veins or getting additional ones. The same measures you can take to treat the discomfort from varicose veins at home can help prevent varicose veins, including:
- Watching your weight
- Eating a high-fiber, low-salt diet
- Avoiding high heels and tight hosiery
- Elevating your legs
- Changing your sitting or standing position regularly
To diagnose varicose veins, your doctor will do a physical exam, including looking at your legs while you're standing to check for swelling. Your doctor may also ask you to describe any pain and aching in your legs.
You also may need an ultrasound test to see if the valves in your veins are functioning normally or if there's any evidence of a blood clot. In this noninvasive test, a technician runs a small hand-held device (transducer), about the size of a bar of soap, against your skin over the area of your body being examined. The transducer transmits images of the veins in your legs to a monitor, so a technician and your doctor can see them.
Fortunately, treatment usually doesn't mean a hospital stay or a long, uncomfortable recovery. Thanks to less invasive procedures, varicose veins can generally be treated on an outpatient basis.
Ask your doctor if insurance will cover any of the cost of your treatment. If done for purely cosmetic reasons, you'll likely have to pay for the treatment of varicose veins yourself.
Self-care — such as exercising, losing weight, not wearing tight clothes, elevating your legs, and avoiding long periods of standing or sitting — can ease pain and prevent varicose veins from getting worse.
Wearing compression stockings all day is often the first approach to try before moving on to other treatments. They steadily squeeze your legs, helping veins and leg muscles move blood more efficiently. The amount of compression varies by type and brand.
You can buy compression stockings at most pharmacies and medical supply stores. Prescription-strength stockings also are available, and are likely covered by insurance if your varicose veins are causing symptoms.
Additional treatments for more-severe varicose veins
If you don't respond to self-care or compression stockings, or if your condition is more severe, your doctor may suggest one of these varicose vein treatments:
Sclerotherapy. In this procedure, your doctor injects small- and medium-sized varicose veins with a solution or foam that scars and closes those veins. In a few weeks, treated varicose veins should fade.
Although the same vein may need to be injected more than once, sclerotherapy is effective if done correctly. Sclerotherapy doesn't require anesthesia and can be done in your doctor's office.
- Foam sclerotherapy of large veins. Injection of a large vein with a foam solution is also a possible treatment to close a vein and seal it.
- Laser treatment. Doctors are using new technology in laser treatments to close off smaller varicose veins and spider veins. Laser treatment works by sending strong bursts of light onto the vein, which makes the vein slowly fade and disappear. No incisions or needles are used.
- Catheter-assisted procedures using radiofrequency or laser energy. In one of these treatments, your doctor inserts a thin tube (catheter) into an enlarged vein and heats the tip of the catheter using either radiofrequency or laser energy. As the catheter is pulled out, the heat destroys the vein by causing it to collapse and seal shut. This procedure is the preferred treatment for larger varicose veins.
- High ligation and vein stripping. This procedure involves tying off a vein before it joins a deep vein and removing the vein through small incisions. This is an outpatient procedure for most people. Removing the vein won't keep blood from circulating in your leg because veins deeper in the leg take care of the larger volumes of blood.
- Ambulatory phlebectomy (fluh-BEK-tuh-me). Your doctor removes smaller varicose veins through a series of tiny skin punctures. Only the parts of your leg that are being pricked are numbed in this outpatient procedure. Scarring is generally minimal.
- Endoscopic vein surgery. You might need this operation only in an advanced case involving leg ulcers if other techniques fail. Your surgeon uses a thin video camera inserted in your leg to visualize and close varicose veins and then removes the veins through small incisions. This procedure is performed on an outpatient basis.
Varicose veins that develop during pregnancy generally improve without medical treatment within three to 12 months after delivery.
Lifestyle and home remedies
There are some self-care measures you can take to decrease the discomfort that varicose veins can cause. These same measures can help prevent or slow the development of varicose veins, as well. They include:
- Exercise. Get moving. Walking is a great way to encourage blood circulation in your legs. Your doctor can recommend an appropriate activity level for you.
- Watch your weight and your diet. Shedding excess pounds takes unnecessary pressure off your veins. What you eat can help, too. Follow a low-salt diet to prevent swelling caused from water retention.
- Watch what you wear. Avoid high heels. Low-heeled shoes work calf muscles more, which is better for your veins. Don't wear tight clothes around your waist, legs or groin because these garments can reduce blood flow.
- Elevate your legs. To improve the circulation in your legs, take several short breaks daily to elevate your legs above the level of your heart. For example, lie down with your legs resting on three or four pillows.
- Avoid long periods of sitting or standing. Make a point of changing your position frequently to encourage blood flow.
Though they haven't been well-studied, a number of alternative therapies claim to be helpful treatments for chronic venous insufficiency, a condition associated with varicose veins in which leg veins have problems returning blood to the heart. These therapies include:
- Horse chestnut
- Butcher's broom
- Grape (leaves, sap, seed and fruit)
- Sweet clover
Talk with your doctor before trying any herb or dietary supplement to make sure these products are safe and won't interfere with any medications.
Preparing for an appointment
There are no special preparations you'll need to make before your appointment. Your doctor will need to look at your bare legs and feet to diagnose varicose veins and figure out what treatment might be best for your condition.
Your primary care doctor may recommend that you see a doctor who specializes in vein conditions (phlebologist), a vascular surgeon or a doctor who treats skin conditions (dermatologist or dermatology surgeon). In the meantime, there are some steps you can take to prepare for your appointment and begin your self-care.
What you can do
Make a list of:
- Your symptoms, including any that may seem unrelated to varicose veins, and when they began
- Key personal information, including a family history of varicose veins or spider veins
- All medications, vitamins or supplements you take, including doses
- Questions to ask your doctor
Some basic questions to ask your doctor include:
- What's the most likely cause of my symptoms?
- Are there other possible causes for my varicose veins?
- What tests will I need?
- What treatment do you recommend for me?
- How can I best manage varicose veins along with other health conditions I have?
- Do I need to restrict any activities?
- Are there any brochures or other printed materials I can have? What websites do you recommend?
What to expect from your doctor
Your doctor is likely to ask you a number of questions, including:
- When did you notice the varicose veins?
- Do you have pain? If so, how severe is it?
- What, if anything, seems to improve your symptoms?
- Does anything appear to worsen your symptoms?
What you can do in the meantime
Even before your appointment, you can begin self-care. Try not to stand or sit in one position for a long time, elevate your legs when you're seated, and avoid uncomfortable footwear and tight socks or hosiery.
