Varicose, Spider Veins, or DVT: Blue or Purple Veins
Blue or purple veins may indicate the presence of dilated and malfunctioning veins. These colors are often associated with increased pressure in the veins and pooling of blood, highlighting the need for further evaluation and potential treatment for varicose veins, spider veins, or DVT to address the underlying venous insufficiency.

What Do Blue or Purple Veins Mean?
Many of us experience some sort of venous disorder at one point or another. Varicose and spider veins aren’t the most pleasing to look at but for the most part, they are relatively harmless. Other venous disorders such as deep vein thrombosis (DVT) can be more severe and require medical attention. Regardless of the type, if you are experiencing sudden changes in appearance or discomfort, it’s important to seek medical attention. Because of their unpleasant appearance , colors, and the fact they are linked to blood clots, many questions arise about varicose veins, spider veins, and DVT.
What Are Venous Disorders?
Using a one-way path system, veins move oxygen-poor blood to our hearts that then pump it to our lungs where it is filtered of waste. From there, oxygen-rich blood is created and pumped back through our hearts and transported to the rest of our bodies. This newly rejuvenated blood gives nutrients and oxygen to our brains, feet, and everything in between.
When the valves in our veins start to malfunction or deteriorate, it causes blood to pool in these areas which causes venous diseases. Blood should continue to flow smoothly along the one-way path through our veins. However, once this collection of blood builds up, it enlarges the veins, stretches them out, and creates various abnormalities that are rope or spider-like in appearance.
According to the National Institutes of Health, varicose veins are are a common condition caused by weak or damaged vein walls and valves. Veins have one-way valves inside them that open and close to keep blood flowing toward the heart. Weak or damaged valves or walls in the veins can cause blood to pool and even flow backwards.

It may involve several factors such as family history, hormone levels, and high blood pressure to develop varicose veins. Don’t let these blood clots last long term and become complications of varicose veins.
Blue Veins on Legs: Causes and Symptoms
Veins that are not protruding from your skin are most likely harmless spider veins. Varicose veins bulge from your skin and contain a lumpy snake-like texture. They are also a sign that your vascular system is having trouble with blood flow in that area. If left untreated, this could pose a risk to future health conditions. Other symptoms to watch for are:
- Swelling: The pressure from the buildup of blood in the veins causes excess fluid to leak out into nearby tissue.
- Ulcers: Between the itching, swelling, and bruising, the lack of nutrients and oxygen prevents the skin from healing properly. Ulcers are essentially open sores that are prone to infection.
- Infection: The stretching and irritation can start to become red and tender. As the infection worsens you may experience a fever and intense pain.
- Itching: A common symptom that happens due to the vein being enlarged and blood leaking through the skin’s pores, causing venous stasis dermatitis.
- Bleeding: Because the skin around varicose veins are extra thin and delicate, simple bumps and nicks can cause external as well as intradermal bleeding. Although it’s nothing to panic about, you should seek a professional’s opinion.

Purple Veins on Legs: Causes and Symptoms
Skin tones can influence the color of veins which are usually in the blue, green, or purple spectrum. However, prominent purple veins could indicate deep vein thrombosis. DVT occurs when a blood clot and inflammation occurs inside a major vein–usually one that’s deep inside the body and hidden by muscle. Blood clots can be life threatening as they are capable of breaking off, traveling to the lungs and blocking arteries which can cause pulmonary embolisms. Four symptoms of DVT your doctor will look for are:
- Hard veins deep inside your skin
- Leg swelling
- Leg Pain
- Inflammation and skin that’s warm to the touch

Complications of Untreated Varicose Veins
Neglecting Treatment for Varicose Veins Can Have Impacts On Your Quality of Life
The long-term effects of varicose veins can vary according to severity but include complications such as:
- Pain and discomfort: Untreated varicose veins can cause pain and discomfort that may limit your activities.
- Swelling in the legs: The increased pressure within the veins can lead to edema resulting in swelling and discomfort.
- Risk of infection: Scratching the skin around varicose veins can potentially lead to infections that might be difficult to treat.
- Blood clot formation (thrombosis): Clots forming within the veins pose a risk of deep vein thrombosis (DVT) which could potentially lead to embolism if a clot dislodges and travels to the lungs.
- Thrombophlebitis: This is a condition characterized by inflammation in the veins, which can cause discomfort such as pain, swelling and redness. As the skin around the veins becomes thinner over time, there is a possibility of experiencing bleeding due to increased vulnerability to injuries.
- Ulcers: Chronic venous ulcers can result in unhealed wounds increasing the risk of infection. Itchy and inflamed skin can progress into dermatitis or eczema causing discomfort and irritation.
- Lipodermatosclerosis: This is a condition where the skin hardens and changes color resembling leather in appearance.
