what does it mean when your leg veins pop out?

Healthy veins have valves that keep blood from flowing down as it is pumped up through the leg. Bulging veins occur when these valves malfunction and allow blood to flow backward and pool into the vein. They can be caused by a number of conditions that affect the vein directly or not.

Besides a surface network of veins, your legs have an interior, or deep, venous network. On rare occasions, an interior leg vein becomes varicose. Such deep varicose veins are usually not visible, but they can cause swelling or aching throughout the leg and may be sites where blood clots can form.

Broken blood vessels — also called “spider veins” — occur when they're dilated, or enlarged, just beneath your skin's surface. This results in small, red lines that spread out into a web-shaped form. They can develop anywhere on the body, but they're more common on the face and legs.

Cold feet or legs: Reduced blood flow in your feet causes them to feel colder than other parts of your body. Swollen legs, ankles, or feet: When your veins can't push blood upward, it can collect in your legs. This blood pooling puts extra pressure on the area, causing fluid buildup and swelling.

Fluid buildup (edema): It happens when the tissues or blood vessels in your legs hold more fluid than they should. This can happen if you simply spend a long day on your feet or sit for too long. But it may also be a sign that you're overweight or don't get enough exercise, or of more serious medical conditions.

If you have CVI, valves in your veins (usually in the leg or sometimes the arms) don't work, causing blood to pool in your legs and putting increased pressure on the walls of the veins. May be due to valve dysfunction (usually hereditary) or due to valve destruction after a deep vein thrombosis (DVT) or blood clot.

If a varicose vein ruptures and the skin is broken, you will experience significant bleeding. Apply immediate pressure to the area with a towel or cotton t-shirt, and elevate your legs above your heart. This will help slow or stop the bleeding while you seek medical attention.

A feeling of sudden leg weakness, causing your legs to give out or buckle can be alarming. Weakness in your leg(s) may occur from problems in the nerves and/or muscles in your lower body and is usually treatable. Rarely, the underlying cause may be a serious medical condition requiring immediate medical attention.

When your heart doesn't pump enough blood to meet your needs, blood often backs up and causes fluid to build up in your lungs (congest) and in your legs, causing your legs to swell and turn blue from lack of oxygenated blood flow (cyanosis). This fluid in your lungs can make you short of breath.

The arteries in the legs are most often affected, which may impair circulation to your feet, causing them to feel cold. Also referred to as venous disease, vein disease refers to various issues that affect blood flow through your veins, including varicose veins and deep vein thrombosis (DVT).

If you have chronic venous insufficiency (CVI), the valves don't work like they should and some of the blood may go back down into your legs. That causes blood to pool or collect in the veins. Over time, CVI can cause pain, swelling, and skin changes in your legs.

As you get older, your skin gets thinner and loses elasticity, making your veins more visible. Also, as you age, your valves in your veins weaken. This can cause blood to pool in your veins for a longer period of time.

Bulging of the veins is a symptom that commonly occurs in different conditions, such as thrombophlebitis, pregnancy, older age, and congenitally defective valves in the veins. Varicose veins are dilated, often distorted, and swollen veins that may be painful. Varicose veins are most frequently seen in the legs.

Broken blood vessels — also called “spider veins” — occur when they're dilated, or enlarged, just beneath your skin's surface. This results in small, red lines that spread out into a web-shaped form.

Although they can be painful and disfiguring, they are usually harmless. When inflamed, they become tender to the touch and can hinder circulation to the point of causing swollen ankles, itchy skin, and aching in the affected limb. Besides a surface network of veins, your legs have an interior, or deep, venous network.

In advanced cases, breakdown of the skin may cause bleeding from varicose veins, and large varicosities may develop blood clots, a condition called superficial phlebitis or thrombophlebitis. If you experience any of these symptoms, talk with your doctor. Do not ignore these symptoms.

One common cause is venous insufficiency, in which damage to valves in the legs' deep veins hinders the return of blood to the heart. This causes fluid to collect and pool in the legs and feet. Superficial varicose veins can also cause legs to swell.
