Poor circulation in your feet can be due to peripheral arterial disease (PAD) which occurs when plaque builds up in the arteries (atherosclerosis), reducing blood flow to the limbs. Common risk factors of PAD include smoking, exposure to secondhand smoke, high blood pressure, high lipids (cholesterol and/or triglycerides), diabetes, obesity, inactivity, age greater than 50, male gender, family history, genetic conditions and ethnicity.
Common symptoms of PAD include pain, fatigue, heaviness, cramping or discomfort in the leg muscles (calf, thigh or buttocks) that occur during activity such as walking or climbing stairs. The location of intermittent claudication depends on where the artery is blocked or narrowed. The pain or discomfort goes away once the activity is stopped and during rest.
