Vein problems in leg due to venous insufficiency can lead to a sensation of your legs feeling heavier than normal, often exacerbated by leg swelling. In the early stages, symptoms may be mild, presenting as slight achiness and tingling. However, as the condition worsens, varicose veins start, causing chronic leg pain and swelling. This progression can make it difficult to perform routine daily activities and may lead to more serious conditions such as Chronic Venous Insufficiency (CVI) and Deep Vein Thrombosis (DVT). Timely diagnosis and treatment are crucial to manage symptoms and prevent complications.
