Symptoms include:
- Visible, rope-like veins
- Swelling, heaviness, or aching in the legs
- Discoloration or ulcers near the ankles
CVI is more popular in older adults and people who stand or sit for long periods. Left untreated, it can cause serious complications like leg ulcers or blood clots.
2. Varicose Veins
Varicose veins are a popular vein disorder that can cause veins—particularly in the legs and sometimes in the arms—to become visibly swollen and twisted. While often considered a cosmetic issue, they may also signal underlying vein dysfunction.
You may spot:
- Dark blue or purple veins that are raised or bulging
- Burning, itching, or throbbing around the veins
- Cramping or fatigue in the affected limb
- Risk factors include genetics, pregnancy, obesity, and long hours of standing.
3. Deep Vein Thrombosis (DVT)
DVT is a serious condition where a bl00d clot forms in a deep vein, typically in the leg or thigh. Though the clot is not always visible, some cases may lead to prominent or bulging surface veins because of blocked blood flow.
Warning signs include:
- Sudden swelling in one leg
- Pain or tenderness, often starting in the calf
- Skin that’s red or warm to the touch
DVT is potentially life-threatening because a clot can travel to the lungs (pulmonary embolism). Immediate medical attention is required.
4. Congestive Heart Failure (CHF)
When the heart can’t pump blood effectively, pressure builds up in the veins, leading to swelling and visible veins—especially in the neck, hands, or lower extremities.
Other signs include:
