A burst blood vessel in the leg can appear suddenly as bruising, bleeding, or discoloration near the skin's surface. It's often linked to increased pressure inside weakened vein walls, underlying varicose veins, or issues affecting healthy blood flow. Recognizing the symptoms, understanding common causes, and seeking proper diagnosis and treatment are key to managing this condition.

Why it matters

Burst blood vessels in the leg can be an indicator of more serious underlying vein health problems, such as chronic venous insufficiency or varicose veins. Identifying and addressing the root cause is important to prevent further complications and recurrence.

The details

A burst or broken blood vessel happens when a small capillary or vein beneath the skin ruptures, leading to visible bruising or discoloration. This often occurs due to increased pressure inside the vein, minor trauma, or weakened blood vessel walls. Symptoms include visible bruising or discoloration, swelling, and tenderness around the affected area. Common causes include physical trauma, repetitive stress, and underlying conditions like varicose veins or venous insufficiency. Diagnosis typically involves a clinical evaluation, physical examination, and potentially a duplex ultrasound to assess blood flow and vein structure.
