Peripheral artery disease (PAD) is a condition characterized by narrowed arteries reducing blood flow to the limbs, usually the legs. Severe PAD can lead to serious complications if not treated. Here are some signs and symptoms indicative of severe PAD:
-
Leg Pain or Cramping: Pain in the legs or buttocks during physical activities such as walking or climbing stairs, which typically goes away with rest (intermittent claudication).
-
Critical Limb Ischemia: Severe PAD can lead to a condition known as critical limb ischemia, which may manifest as:
- Rest pain: Persistent pain in the feet or toes, especially when lying down, indicating insufficient blood flow.
- Non-healing wounds or sores: Ulcers or wounds on the legs or feet that do not heal.
- Gangrene: Tissue death due to lack of blood flow, which can lead to severe infection and may require amputation.
-
Coldness in the Lower Leg or Foot: A noticeable difference in temperature between the affected limb and the other limb, often with a cool or cold feeling in the affected leg or foot.
-
Weak or Absent Pulse: Weak or non-palpable pulse in the legs or feet.
-
Skin Changes:
- Changes in color (pale or bluish skin) on the legs or feet.
- Shiny skin or hair loss on the legs or feet.
- Thickened toenails or a change in nail growth.
-
Changes in Sensation: Numbness or weakness in the legs.
-
Severe Fatigue in the Legs: Excessive tiredness or heaviness in the legs after minimal physical activity.
-
Foot Ulcers or Infections: Development of non-healing sores on the feet or legs, which can lead to infections.
If you or someone you know is experiencing these symptoms, it's essential to seek medical attention promptly, as severe PAD can increase the risk of heart attack, stroke, and complications leading to amputation.
