2. Varicose Veins
What It Is
Varicose veins are enlarged, twisted superficial veins—usually in the legs—that appear dark blue or purple. While often considered cosmetic, they can indicate deeper circulation problems.
Symptoms
-
Bulging or raised veins
-
Itching, burning, or throbbing
-
Leg fatigue or restlessness
-
Pain that worsens after prolonged standing
Risk Factors
-
Genetics
-
Obesity
-
Pregnancy
-
Prolonged sitting or standing
Note: If left untreated, varicose veins can progress to CVI or increase the risk of deep vein thrombosis (DVT).
3. Deep Vein Thrombosis (DVT)
What It Is
Deep Vein Thrombosis is a medical emergency in which a blood clot forms in a deep vein—usually in the leg or thigh. While the clot itself isn’t visible, it can cause surface veins to become more prominent due to swelling and blocked blood flow.
Warning Signs
-
Sudden swelling in one leg (not both)
-
Pain or tenderness, often starting in the calf
-
Warmth and redness over the affected area
-
Visible, engorged veins
🚨 Urgent: If a clot breaks loose, it can travel to the lungs and cause a pulmonary embolism, which can be fatal.
👉 Seek immediate medical care if you experience these symptoms.
