Do your legs feel heavy, tired, or achy by the time the day ends? You're not alone. Millions of people experience evening leg fatigue, but many chalk it up to aging, being on their feet too long, or simply “normal” tiredness. In reality, persistent leg fatigue can be a sign of an underlying condition—especially chronic venous insufficiency (CVI) or poor circulation.
At Sheen Vein & Cosmetics, we help patients get to the root of leg discomfort, offering both advanced diagnostics and non-surgical solutions. If you're wondering “why do my legs get tired at the end of the day?”—this blog will walk you through the top causes and what you can do to find lasting relief.
You may notice these symptoms gradually appear throughout the day:
These symptoms tend to worsen with prolonged standing or sitting—and often improve with leg elevation or rest.
One of the most common (yet underdiagnosed) causes of tired legs is chronic venous insufficiency, a condition where the valves in your leg veins don’t work properly. This leads to blood pooling in the legs instead of returning efficiently to the heart.
Risk Factors:
Why It Gets Worse at Day’s End:
Gravity is constantly working against your veins. As you move through your day, blood tends to pool in your lower extremities. By evening, this pressure builds up, resulting in heaviness, aching, and fatigue.

Tired legs are often the first subtle symptom of varicose veins—even before you see them. Varicose veins are bulging, twisted veins caused by valve dysfunction, while spider veins are smaller, web-like clusters visible under the skin.
These vein issues indicate poor blood flow and increased pressure in the legs, leading to:
Important: You don’t have to see large bulging veins to have vein disease. Many patients experience discomfort long before any visible signs appear.

While venous issues cause blood pooling, PAD involves narrowed arteries that reduce blood flow to the legs. This is less common but more serious.
If you have diabetes, high blood pressure, or a history of smoking, PAD should be ruled out as a potential cause of leg fatigue.
Leg fatigue can also be caused by imbalances in key nutrients that support circulation, nerve health, and muscle function.
A simple blood test can uncover whether these imbalances are playing a role in your symptoms.

If your lymphatic system isn’t draining properly, you may feel heaviness, tightness, or swelling—especially in the lower legs.
Signs of lymphatic stagnation:
Manual lymphatic drainage, red light therapy, or PEMF therapy can help support detox and reduce tissue congestion.
Many women experience end-of-day leg swelling or fatigue around hormonal changes, including:
Estrogen and progesterone influence blood vessel tone and fluid retention. For some women, this can trigger increased vascular pressure in the legs.
