Symptoms
Many people who have
peripheral arterial disease (PAD) do not have
symptoms.
If you do have symptoms, you may have a tight, aching, or squeezing
pain in the calf, thigh, or buttock. This pain, called
intermittent claudication, usually happens after you
have walked a certain distance. For example, your pain may always start after
you have walked a block or two or after a few minutes. The pain goes away if
you stop walking. As PAD gets worse, you may have pain in your foot or toe when
you are not walking.
But, not everyone has intermittent claudication. About 1 out of 5
people with PAD may have intermittent claudication.2
Some people with PAD do not have leg pain simply because they do not walk far
enough to bring intermittent claudication on.
Other symptoms of peripheral arterial disease of the legs may
include:
- Weak or tired legs.
- Difficulty
walking or balancing.
- Cold and numb feet or toes.
- Sores
that are slow to heal.
- Foot pain while you are at rest, which
indicates that PAD is getting worse.
- Erectile
dysfunction.
Physical signs of advanced peripheral arterial disease of the legs
may appear, such as:
- Feet and toes that become pale from exercise or
when elevated.
- Loss of hair on the feet and toes.
- Feet
that turn red when dangled.
- Blue or purple marks on the legs,
feet, or toes, caused by reduced oxygen flow to the tissues.
- Ulcers
on the feet or toes.
- Gangrene
infection (death of tissue), indicated by black skin on the legs or
feet.
More severe symptoms may indicate advanced PAD. But symptoms can be
affected by or confused with other health conditions the person also has, such
as
arthritis.
Peripheral arterial disease also can be confused with
other conditions with similar symptoms.
Symptoms of leg pain associated with PAD may be mentioned less
often by people who have a high pain tolerance, by people with conditions like
diabetes who have numbness in their legs that prevents
them from sensing pain, or by people who never exert themselves long enough for
leg pain to start. These factors may keep peripheral arterial disease from
being diagnosed.
