Pain at Rest

    When peripheral vascular disease (PVD) progresses, it can lead to a variety of serious symptoms. One of these symptoms is pain at rest, which is a severe pain in the legs and feet that occurs while a person is resting.1  Unlike exercise pain, which is brought on by mere activity, pain at rest can strike at any moment when lying down or when legs are elevated, which may produce burning or cramping discomfort.

    Symptom Details


    Although pain at rest can happen anytime, it typically occurs at night during sleep. People may awaken to severe burning sensations in their lower legs or feet, which may become chronic and persistent. This pain may be temporarily relieved by hanging a foot or leg over the bed.


    When a person experiences pain at rest, it can signify a severe blockage in the arteries of the lower extremities.2 The blockage happens when the arteries become narrowed and hardened due to excessive plaque build-up and can significantly reduce blood flow to the area.


    Pain at rest can be a sign of advanced peripheral artery disease, also called critical limb ischemia (CLI).3 Over time, pain at rest can lead to more serious complications, such as tissue loss and leg ulcers. The skin can break down and develop non-healing wounds.1 Therefore, it is critical to take the step and see your doctor right away if you experience this symptom.


    This is how pain at rest symptoms typically progress: 1,2,3


    • Pain at rest, which comes and goes
    • Pain that occurs at night or while sitting
    • Weak pulse that may be hard to find in legs and feet


    • Pain may progress in its severity
    • Possible loss of sensation in the legs
    • Weakness in the legs may occur
    • Pain may subside when standing
    • Elevation of the legs increases pain


    • Resting pain may become chronic and persistent and may interrupt normal resting routines
    • Leg ulcers, or non-healing wounds may develop due to restricted blood flow that causes further tissue damage
    • Gangrene, or black toe, can occur as the surrounding tissue dies



    Pain at rest is a result of progressive and chronic blockage of the arteries to the legs and feet. When your body does not get the healthy blood flow it needs, pain may occur.


    With a chronic lack of oxygen to the tissue, the skin can begin to break down and form leg ulcers, or other types of non-healing wounds. As the lack of blood flow progresses, the area may not heal and can lead to limb amputation or other complications.5

    Risk Factors

    Although PVD diseases range in symptoms and causes, they all carry certain risk factors.


    For pain at rest, in addition to vascular conditions, other risk factors include:3


    • Certain medical conditions such as high cholesterol, high blood pressure and diabetes can increase the likelihood of developing arterial disease
    • Smoking, which can damage the arteries and their ability to transport blood
    • Obesity or being overweight can also put pressure on your legs and restrict healthy blood flow
    • Being older than 60 can increase the risk of developing pain at rest as blood vessels are more likely to become damaged over time
    • Inactive lifestyle and poor diet can be a factor

    What to Look For


    Pain at rest does not usually begin on its own. Instead, the condition may stem from untreated peripheral artery disease (PAD).


    The Rutherford Classification is a common system that is widely used to diagnose and identify the severity of arterial disease. Here are how the symptoms progress:

    Rutherford Classification 6

    Stage 0

    Stage 1

    Stage 2

    Stage 3

    Stage 4

    Stage 5

    Stage 6

    No symptoms

    Some exercise pain after walking long distances

    Exercise pain that occurs more frequently at shorter distances

    Severe exercise pain that happens frequently after a short distance

    Pain in the legs, calves, buttocks that occurs despite rest

    Leg ulcers begin to develop

    Severe non‑healing wounds can lead to gangrene or tissue loss

    If you notice signs of advanced artery disease, it is important to see your doctor right away as the condition requires immediate care.4

    Associated Symptoms

    Exercise Pain

    A common early symptom of PAD is exercise pain, or arterial claudication which produces cramping pain or discomfort in the legs, thighs, feet or buttocks.

    Non-healing wounds

    Poor blood circulation can lead to skin break down, open wounds, or ulcers, that require prompt medical attention. When the sores are open, they allow for bacteria and air to enter the wound, which can make the condition worse.


    When blood flow to the toes is cut off, tissue can die and turn black. This is called gangrene and it can lead to tissue loss or amputation.

    When to See a Doctor


    Exercise pain may be a sign of a serious venous or arterial disease. Appropriate treatment of these conditions is important not only to prevent progression of disease.


    If you notice intermittent pain in your legs during exercise, it is important to take the step to get help right away.
