Leg Pain at Night: Watch Out for Peripheral Artery Disease

Written By Center for Vein Restoration
Leg pain at night

Do you find your sleep interrupted by leg pain or discomfort? While it may seem like a common issue, especially after a day of strenuous activity, tell your vascular specialist if you're experiencing consistent nighttime leg pain. Consistent nighttime leg pain and discomfort could be a symptom of Peripheral Artery Disease (PAD), a condition that affects millions but often goes unrecognized until it progresses.

What Does Your Nightly Leg Pain Mean?

If leg pain interrupts your sleep or has made you change your sleep routine, you should talk to your vascular specialist. Leg pain at night can have mundane causes but can also indicate more serious underlying vascular issues such as peripheral artery disease or PAD.

Peripheral artery disease is a circulatory condition where arterial narrowing reduces blood flow to your limbs. For patients who develop peripheral artery disease, your extremities, most commonly your legs, don't receive enough blood flow to keep up with demand. This change in blood flow can cause various symptoms, with leg pain at night being one of the most common.

The primary cause of PAD is atherosclerosis, a condition caused by plaque buildup in your arteries, which narrows and blocks arteries, significantly reducing blood flow.

The pain intensifies at night due to the decreased blood circulation while lying down. The horizontal position can exacerbate the blood flow restriction, leading to heightened pain or cramping.

Leg pain at night can be caused by various conditions, ranging from mild to severe. Common causes for leg pain at night include but aren't limited to:

Peripheral Artery Disease (PAD): As mentioned earlier, PAD occurs when arteries in the legs are narrowed or blocked by plaque, reducing blood flow to your limbs. Reduced blood flow can cause cramping, pain, or tiredness in the leg muscles, particularly at night.

Restless Legs Syndrome (RLS): RLS is a disorder that causes an uncontrollable urge to move your legs, usually because of uncomfortable sensations like a burning, itching, tingling, or "bubbling" feeling. Patients with RLS typically experience symptoms in the evening or nighttime when sitting or lying down.

Muscle Cramps: Also known as "Charley horses," these sudden, involuntary muscle contractions are often painful and can cause significant discomfort during the night. They may be related to muscle fatigue or electrolyte imbalances.

Chronic Venous Insufficiency (CVI): Chronic venous insufficiency occurs when your leg veins don't allow blood to flow back to your heart correctly. Venous insufficiency can cause pain, swelling, and leg cramps at night.

Neuropathy: Diabetic or peripheral neuropathy often causes tingling, numbness, burning, or leg pain that can worsen at night.

Arthritis: Osteoarthritis or rheumatoid arthritis can cause joint pain that worsens at night, leading to leg discomfort.

Sciatica: This condition causes pain that radiates along the path of the sciatic nerve, which extends from the lower back through the hips and buttocks and down each leg. It can worsen at night, especially when lying in certain positions.

Medication Side Effects: Some medications can cause leg pain or discomfort as a side effect.

Poor Circulation: Poor circulation can lead to discomfort and pain in the legs at night due to decreased blood flow.

Exercise: Overexertion or high-intensity exercise without adequate stretching or recovery can lead to muscle pain at night.

Nutritional Deficiencies: Being dehydrated or lacking minerals such as potassium, calcium, or magnesium can contribute to leg cramps and pain.

Feeling aches and pains as your body relaxes before falling asleep is normal, but severe, sharp, or constant pain shouldn't be ignored.

Seek immediate medical attention if you experience?

  • Sudden, severe leg pain

  • Leg pain accompanied by chest pain or difficulty breathing

  • A leg that is cold, pale, blue, or numb

  • Swelling in one leg accompanied by pain or tenderness

These symptoms could be a symptom of a blood clot or deep vein thrombosis (DVT), a medical emergency.

The Center for Vein Restoration offers DVT Rule-Out Services designed to reassure you without needing an expensive and time-consuming visit to the emergency room. Our all-encompassing service includes scans, anticoagulation therapy, educational support, and follow-up care as necessary. If you're experiencing any of the symptoms mentioned, please contact our DVT hotline at 877-SCAN-DVT (877-722-6388) for assistance.

How Do I Know if My Nightly Leg Pain is Peripheral Artery Disease?

Symptoms of peripheral artery disease can range from mild to severe, and some individuals may not experience any symptoms at all. However, when symptoms do occur, they may include:

Muscle Pain and Cramping: Muscle pain and cramping or "claudication" in the legs or arms after activity is a common symptom of peripheral artery disease. Peripheral artery disease patients typically describe the symptoms as aching, cramping, numbness, weakness, or a sense of fatigue in the muscles.

Pain at Rest: In more severe cases, PAD can cause pain in the feet or toes, even when lying down or at rest. The pain may be intense enough to disrupt sleep. Elevating the legs may exacerbate the pain, while dangling them over the edge of the bed or walking may provide some relief.

Coldness in the Lower Leg or Foot: This symptom is particularly noticeable compared to the other side.

Numbness or Weakness in the Legs: These sensations may be signs of reduced blood flow.

Change in the Color of the Legs: This can include paleness or blueness (cyanosis).

Sores on Toes, Feet, or Legs That Won't Heal: Poor blood circulation can prevent sores or injuries from healing properly, leading to chronic wounds.

Pulse Changes in the Legs: Weakened or absent leg or foot pulses can indicate PAD.

It's important to note that the severity of the symptoms does not always correspond to the severity of the PAD. Some individuals with significant narrowing of the arteries may not experience any symptoms, while others with mild PAD may have noticeable symptoms.

If you suspect you have PAD or experience any of these symptoms, it's crucial to seek medical evaluation and treatment to prevent the progression of the disease and potential complications.

Am I At Risk for Peripheral Artery Disease?

Several risk factors increase the likelihood of developing peripheral artery disease, some of which can be modified or treated, while others, such as age and genetics, cannot be changed. Understanding these risk factors can help in the prevention and early detection of peripheral artery disease.

Risk factors associated with peripheral artery disease include but aren't limited to:

Smoking: Smoking is a significant risk factor for PAD, as well as for other atherosclerotic diseases. The risk of PAD increases with the length of time and the number of cigarettes smoked.

Diabetes: People with diabetes are at a higher risk of developing PAD. High blood sugar levels can damage arteries and hinder blood flow.

Age: The risk of PAD increases with age, particularly after reaching 50 years old.

High Blood Pressure: Hypertension can cause damage to the arteries, making them more susceptible to atherosclerosis.

High Cholesterol: High cholesterol levels in the blood can contribute to forming plaques in the arteries, leading to their narrowing and disrupting blood flow.

Obesity: A body mass index (BMI) of 30 or higher increases the risk of PAD.

Sedentary Lifestyle: Lack of physical activity can contribute to the development of PAD and other cardiovascular diseases.

Family History of PAD, Heart Disease, or Stroke: Genetics can play a role in an individual's susceptibility to PAD. A family history of PAD or other cardiovascular diseases increases the risk.

It's essential to manage these risk factors through lifestyle changes and, where appropriate, medication. You can make lifestyle changes to improve your vascular health and decrease your risk of developing or worsening peripheral artery disease.

Lifestyle changes include but aren't limited to:

  • Quitting smoking

  • Limiting alcohol intake

  • Maintaining healthy blood sugar levels, especially if diabetic

  • Maintaining healthy blood pressure and cholesterol level

  • Adopting a physically active lifestyle

  • Achieving and maintaining a healthy weight

  • Following a heart-healthy diet

  • Attending regular checkups with your healthcare provider

Making changes to your lifestyle is the first step in managing PAD. Treatment includes medication to manage symptoms and address underlying causes, including drugs to lower cholesterol and blood pressure. For more severe cases, your vascular specialist may recommend procedures like angioplasty, stenting, or atherectomy may be advised to restore blood flow.

Talking to Your Vascular Specialist About Peripheral Artery Disease

Early diagnosis is critical to managing peripheral artery disease effectively. It starts with a comprehensive medical history and physical examination.

The Ankle-Brachial Index (ABI) test is a simple, non-invasive procedure that measures the blood pressure in your ankles compared to your arms to indicate PAD.

Imaging tests such as ultrasound, angiography, and blood tests can provide your vascular specialist with further insights into the causes of your leg pain and discomfort. They'll also take a comprehensive medical and family history, so be sure to come prepared with any questions you may have and information at the ready.
