Neurogenic claudication commonly describes pain, weakness, fatigue, tingling, heaviness and paresthesias that extend into the lower extremities. [9] These symptoms may involve only one leg, but they usually involve both. Leg pain is usually more significant than back pain in individuals who have both. [12]
Intermittent claudication is a symptom and is by definition diagnosed by a patient reporting a history of leg pain with walking relieved by rest. However, as other conditions such as sciatica can mimic intermittent claudication, testing is often performed to confirm the diagnosis of peripheral artery disease .
Claudication is a medical term usually referring to impairment in walking, or pain, discomfort, numbness, or tiredness in the legs that occurs during walking or standing and is relieved by rest. [1] The perceived level of pain from claudication can be mild to extremely severe.
The classic symptom is leg pain when walking, which resolves with rest and is known as intermittent claudication. [2] Other symptoms include skin ulcers, bluish skin, cold skin, or abnormal nail and hair growth in the affected leg. [3]
Rest pain is a continuous burning pain of the lower leg or feet. It begins, or is aggravated, after reclining or elevating the limb and is relieved by sitting or standing. It is more severe than intermittent claudication, which is also a pain in the legs from arterial insufficiency. [citation needed]
Symptoms may also include intermittent claudication or pain at rest. In late stages, paresthesia is replaced by anesthesia (numbness) due to death of nerve cells. [ 11 ] In severe cases, gangrene can occur suddenly and spread rapidly, [ 12 ] and should be treated within six hours of ischaemia.
Lying on the side is often more comfortable than lying flat, since it permits greater lumbar flexion. Vascular claudication can resemble spinal stenosis, and some individuals experience unilateral or bilateral symptoms radiating down the legs rather than true claudication. [7] The first symptoms of stenosis include bouts of low back pain.
Narrowing of the lumbar spinal canal causes a clinical condition known as neurogenic claudication, characterized by symptoms such as lower back pain, leg pain, leg numbness, and leg weakness that worsens with standing and walking and improves with sitting and lying down. [6]
