Peripheral Artery Disease
Up to half of people with peripheral artery disease have no symptoms. The most common symptom is pain in the calves, thighs, or buttocks when you exercise these muscles. This pain is called “claudication” and is caused by the inability of the narrowed artery to supply enough blood to the working muscle. Some patients have “intermittent claudication”—pain that occurs with exercise and subsides with rest. When blockages in the artery become severe, pain can occur even at rest, especially when lying down at night.
Other symptoms of peripheral artery disease include:
- Leg numbness or weakness
- Coldness in your lower leg or foot
- Sores on your legs or feet that won't heal
- A change in the color of your legs
- Loss of hair on your feet and legs
- Slower growth of your toenails
- Shiny skin on your legs
- Erectile dysfunction in men
Older adults may have decreased blood flow to their legs or feet, and even serious tissue damage, without being aware of it. That’s because circulation problems can decrease pain sensations, and poor vision may make it difficult to see skin color or texture changes. Older adults with diabetes are at special risk, because of the nerve and vision damage that diabetes can cause. Be sure your healthcare provider examines your feet and circulation in your legs frequently.
Older adults may also assume their leg or foot pain is due to other causes, such as arthritis, so it is important to tell your healthcare provider about any pain you are having.
