Persistent leg itching is often mistaken for a skin condition or allergy. However, if the itching recurs frequently or worsens at night, it may indicate varicose veins as the underlying cause. This symptom goes beyond surface-level irritation and may signal impaired venous function.

Varicose veins arise when the valves in the leg veins weaken, causing blood to flow backward and pool, leading to swollen, protruding veins. This pooling can inflame surrounding tissues, triggering symptoms like itching, a burning sensation, or dry, flaky skin.

If the itching is accompanied by sensations of tightness, heaviness, or aching in the legs, it may be indicative of varicose veins. The discomfort commonly affects the calves and areas below the knees. Excessive scratching may lead to redness, oozing, or secondary skin infections.

Unlike common skin irritations, itching caused by varicose veins rarely responds to standard topical creams. The core problem stems from impaired vascular function, not the skin itself. For this reason, seeking evaluation from a vascular surgeon is crucial, instead of dismissing the symptoms as a simple skin irritation.

Treatment depends on severity and may include compression stockings, medications, sclerotherapy, or laser-based procedures. In early stages, simple lifestyle changes can significantly ease symptoms. Avoiding prolonged standing or sitting with legs lowered and elevating the legs above heart level before bed can provide relief.

Even mild, recurring itching should be evaluated for its underlying cause. Varicose veins are more than a cosmetic issue; if left untreated, they can progress to serious complications such as skin ulcers.
