Vascular Causes of Leg Cramps
Primary Vascular Causes
- Peripheral arterial disease (PAD) can cause claudication, which presents as reproducible leg pain during exercise that resolves with rest, according to the American Heart Association 1, 2
- Claudication is characterized by pain caused by insufficient blood flow during exercise, typically relieved by rest, as stated by the American Heart Association 1, 2
- Location-specific symptoms of vascular disease include hip, buttock, and thigh pain caused by iliac artery disease, calf pain caused by femoral and popliteal artery disease, and calf or foot pain caused by tibial artery disease, as reported by the American Heart Association 2, 3
- Critical limb ischemia is a severe decrease in limb perfusion that causes chronic ischemic rest pain, ulcers, or gangrene, according to the American Heart Association 4
Diagnostic Approach for Vascular Causes
- The American Heart Association recommends assessing for diminished pulses, bruits, and other signs of peripheral arterial disease through physical examination 1, 2
- The ankle-brachial index (ABI) is considered for suspected vascular causes of leg cramps, as recommended by the American Heart Association 1, 4
Differentiating Leg Cramps from Other Conditions
- Restless leg syndrome is characterized by unpleasant sensations with an urge to move, symptoms that begin or worsen during rest, relief with movement, and symptoms that are worse in the evening or night, as stated by the American Academy of Sleep Medicine 5
- Claudication can be differentiated from pseudoclaudication, which is caused by spinal stenosis, venous disease, chronic compartment syndrome, osteoarthritis, and inflammatory muscle diseases, as reported by the American Heart Association 2
Medical Conditions Associated with Leg Cramps
- The American Academy of Neurology states that neurological conditions such as peripheral neuropathy, radiculopathies, lumbar canal stenosis, and Parkinson's disease can be associated with leg cramps 5
