What is a common symptom of chronic venous insufficiency?

Chronic venous insufficiency (CVI) is a condition characterized by the impaired flow of blood in the venous system, particularly in the lower extremities. A primary symptom of this condition is swelling in the legs, known as edema. This swelling occurs due to the accumulation of blood and excess fluid in the tissues when the venous valves become incompetent, allowing blood to pool rather than returning to the heart effectively.

In CVI, this swelling can be exacerbated after prolonged periods of standing or sitting, as gravity plays a significant role in the pooling of blood. It may also be accompanied by other symptoms such as pain or heaviness in the legs, skin changes, and sometimes ulcers. Recognizing swelling as a hallmark symptom is crucial for the diagnosis and management of chronic venous insufficiency, distinguishing it from other vascular or systemic conditions that might manifest differently.
