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.
