According to Brett Carol, a doctor of Harvard Medical School, if there is blockage in the veins of the feet, it is as dangerous as the blockage in the veins of the heart. This means that foot pain can also be an early sign of heart disease.

If you are at risk of heart disease, then the pain in the feet can be peripheral artery disease (PAD). This is the same disease in which blockage is formed in the arteries and blood flow starts to stop. The reasons for pad and heart disease (CAD) are almost the same.

Pad occurs when a layer of calcium and cholesterol accumulates in the arteries carrying blood in the feet. This layer is called plaque. Gradually it blocks the plaque veins and the blood does not flow properly, which makes the feet feel pain and weakness.

Pad is seen in most of the aged people. According to the data, 1 person in about 20 above 50 years and 1 person in 5 above 70 years is affected by this disease. Meaning, its risk also increases with aging.

The biggest symptom of pad is calf or thigh pain while walking and pain decreases when relaxing. This is called cladication. Apart from this, the hair of the feet falls, the legs in the legs which do not fill up quickly and feel heaviness in the feet are also its symptoms.

Pad is due to the same reasons which cause heart disease. These include diabetes, high cholesterol, high blood pressure and smoking. Smoking of these is considered to be the biggest risk factor because it causes direct damage to the veins.

If there is frequent pain in the legs, then doctors can identify the PAD by testing the name Ankle-Brachial Index. At the same time, if you want to be careful yourself, then walking and regular exercise is very beneficial. This improves blood flow to the feet and improves the condition.
