Varicose Veins: Why Your Legs Hurt and What Helps

She noticed them in her late 40s, after a decade of 12-hour nursing shifts: blue threads behind her knees, then rope-like veins up her calves by the end of every shift. Her legs throbbed — like walking through wet sand.

If that story sounds familiar, you are in enormous company. Estimates vary, but researchers generally agree that roughly one in four American adults has varicose veins — and among women, the number climbs to about one in three. They are the single most common vein problem in the United States, and they ache, swell, itch, and cramp.

Here is why they happen, when they are a warning sign, and the fixes that actually help — most of which need no doctor's visit at all.

What a varicose vein actually is

Your leg veins have a tough job. Unlike arteries, which get a push from the heartbeat, veins have to return blood uphill — from your feet all the way back to your heart, fighting gravity the entire way. To do that, veins contain one-way valves that snap shut between heartbeats so blood does not slide backward.

Varicose veins form when those valves weaken or fail. Blood pools, pressure builds, and the vein wall stretches out like an overfilled water balloon. Twisted, enlarged, and bulging above the skin surface — that is what you are looking at.

Anyone can develop them, but the odds stack up if you:

• Stand or sit for long hours. Nurses, teachers, hairdressers, retail workers, TSA agents, and line cooks all top the risk list.
• Have a family history. Vein problems run strongly in families — if your mother had them, your risk roughly doubles.
• Are over 50. About half of people over 50 show some sign of venous disease.
• Are female or have been pregnant. Hormones relax vein walls, and a growing uterus presses on pelvic veins. Veins that bulged during pregnancy often improve afterward — but not always.
• Carry extra weight. Extra pounds add pressure on leg veins.

The symptoms most people ignore

Here is what many Americans miss: varicose veins do not always look dramatic. Plenty of people have aching, heavy, swollen legs for years without a single visible bulge — a condition doctors call chronic venous insufficiency. If your legs feel fine in the morning and progressively worse as the day goes on, your veins may be telling you something.

Common symptoms:

• Heaviness or aching in the legs, especially after standing
• Swelling around the ankles that eases overnight
• Nighttime cramps or a restless, crawling sensation in the calves
• Itching over or around the veins
• Skin changes — darkening or dryness near the ankle, a sign the vein disease is advancing

When varicose veins are a red flag

For most people, varicose veins are uncomfortable but not dangerous. But three situations deserve prompt medical attention:

1. Sudden, significant swelling or pain in ONE leg. That can signal a deep vein thrombosis (DVT) — a clot in a deep vein, which is far more dangerous than surface varicose veins. The CDC estimates DVT and pulmonary embolism affect up to 900,000 Americans a year. If one calf suddenly swells, reddens, and hurts, go to urgent care or the ER.
2. An open sore near the ankle that will not heal. Venous leg ulcers affect hundreds of thousands of Americans annually and mean the circulation problem has reached a stage that needs a vascular specialist.
3. Bleeding from a vein. A fragile varicose vein can rupture from a bump or scratch. It looks alarming — and it can be — but you can usually stop it by lying down, raising the leg above heart level, and pressing firmly for 15 minutes. Get checked afterward.

Also worth a doctor's visit: veins that are warm, red, and tender along their length (possible superficial thrombophlebitis) or symptoms that are clearly getting worse over months.

What actually helps — backed by vascular doctors

There is no cream or supplement that makes varicose veins vanish (despite what the internet advertises). But these strategies genuinely slow progression and ease symptoms:

1. Move your calves — they are your "second heart"

Your calf muscles act as a pump, squeezing deep veins with every step and pushing blood upward. Long stillness is the enemy. If you sit or stand all day, do 10 calf raises or ankle circles every 30 minutes, and take a short walk at least once an hour. Walking, swimming, and cycling are the three best exercises for vein health.

2. Wear compression stockings

This is the single most effective at-home measure, and vascular surgeons recommend it first. Graduated compression stockings (tightest at the ankle, looser at the knee) do the valves' job for them, reducing swelling and aching. Over-the-counter 15–20 mmHg knee-highs are a good starting point; 20–30 mmHg pairs are stronger and may need a fitting. Put them on before you get out of bed, when swelling is lowest.

3. Elevate — correctly

Prop your legs so your feet are above the level of your heart — higher than most people bother with. Fifteen minutes, three to four times a day, lets pooled blood drain. A few pillows on the couch armrest works; a footstool does not (it is below heart level and does little).

4. Maintain a healthy weight and ease up on salt

Shedding excess pounds directly lowers the pressure inside your leg veins. Cutting back on salty processed foods helps too, since sodium makes your body hold water — and that water ends up swelling your ankles.

5. Ease up on heat, tight clothes, and crossed legs

Very hot baths dilate veins and worsen the heavy-leg feeling — end showers with a cool rinse on your legs instead. Tight waistbands and calf-pinching boots restrict venous return, and hours of crossed legs compress veins behind the knee. None of these cause varicose veins, but all make existing ones grumpier.

If you want them gone: modern treatments

A decade or two ago, treating varicose veins meant "vein stripping" — surgery with a hospital stay and a long recovery. That era is over. Today's standard treatments are done in an outpatient clinic, often in under an hour, and most people walk out the same day:

• Endovenous ablation (laser or radiofrequency): A thin catheter seals the faulty vein shut from the inside using heat. Your body reroutes blood through healthy veins. This is now the first-line treatment in the US.
• Sclerotherapy: A solution injected into smaller spider or varicose veins makes them collapse and fade — usually a series of quick office visits.
• Microphlebectomy: Bulging veins are removed through tiny nicks that need no stitches.

Insurance typically covers treatment when it is medically necessary — documented pain, swelling, skin changes, or ulcers after a trial of compression therapy. Purely cosmetic treatment usually is not covered.

The bottom line

Varicose veins are one of the most ordinary things in American medicine — and one of the most shrugged-off. Try compression, movement, and elevation first; they genuinely help. And if one leg suddenly swells and hurts, or an ankle sore refuses to heal, get checked — those are the two signs that mean business.
