Introduction:
Leg and foot cramps are often blamed on things like dehydration, low minerals or getting older. But in some people, poor vein function, known as chronic venous insufficiency, can be the real cause. This case shows how severe leg cramps can actually come from vein disease and how a simple, minimally invasive treatment can bring fast, lasting relief.

Patient Background:
A 75-year-old woman came in with worsening foot and leg cramps that made it hard to sleep or walk comfortably. The cramps usually struck at night and during long periods of standing or walking. She had tried common remedies such as magnesium and potassium supplements, but they barely helped.

Symptoms:

Intense foot and leg cramps, especially at night
Cramping that started or worsened while standing or walking
Sleep interruption from painful cramps
Muscle tightening that made walking difficult

Diagnosis:
An ultrasound exam showed backward blood flow (reflux) in the main surface veins of her leg, the great saphenous vein and nearby accessory veins, confirming chronic venous insufficiency.

Treatment:
The patient had radiofrequency ablation, a quick, minimally invasive procedure that closes off faulty veins using controlled heat. This redirects blood into healthy veins.

Results:
The results were almost immediate. Her leg and foot cramps stopped completely, and she regained normal mobility and sleep within days. The improvement in her quality of life was dramatic.
