Why do my legs hurt only when I walk and feel better when I rest?
Leg pain that arises consistently after a certain distance of walking and resolves with rest has a specific name: claudication. The word itself simply means a limp, but in clinical use it refers to this particular pattern of activity-induced symptoms. In adults over fifty, claudication almost always reflects one of two underlying problems, and distinguishing between them shapes both the workup and the treatment.
The first is neurogenic claudication, caused by lumbar spinal stenosis — narrowing of the bony canal through which the spinal nerves travel. With age, the bones, joints, and ligaments around the lumbar spine can thicken and enlarge, gradually reducing the space available for the nerves. When a person stands upright and walks, this narrow space becomes even tighter, and the nerves are compressed enough to produce leg pain, heaviness, or cramping. The distinguishing feature is that leaning forward relieves the symptoms — many patients describe being able to walk much further when pushing a shopping cart, leaning against a railing, or walking uphill. Sitting down usually resolves the pain within a few minutes.
The second is vascular claudication, caused by peripheral arterial disease — narrowing of the arteries that supply blood to the legs. Here the underlying problem is reduced oxygen delivery to the working muscles. The symptoms typically occur at a fairly predictable walking distance and resolve with standing rest, regardless of body position. Cool feet, weak pulses, and slow-healing wounds on the legs may be additional clues.
The two conditions can coexist, particularly in older adults, and they are sometimes difficult to separate by symptoms alone. Lumbar MRI is the standard study when neurogenic claudication is suspected. Vascular Doppler studies or the ankle-brachial index help diagnose peripheral arterial disease. The two evaluations are not mutually exclusive and are often performed together when the clinical picture is mixed.
If walking distance has been steadily decreasing, if leg symptoms are limiting daily activities, or if there is associated weakness or numbness, evaluation by a spine specialist is appropriate. Lumbar spinal stenosis is initially managed with a combination of activity modification, physical therapy, and selective injections; surgical decompression is considered when conservative care no longer maintains adequate quality of life.
- Is arm tingling always caused by a cervical disc problem?
Not necessarily. While cervical disc herniation is a common cause and typically follows a dermatomal pattern (e.g., C6 affects the thumb and index finger), other conditions — peripheral neuropathy, carpal tunnel syndrome, vascular insufficiency, thoracic outlet syndrome — can produce similar symptoms.
- When is cervical disc surgery indicated?
Surgery is generally considered after conservative treatment fails (typically 6–12 weeks) or when specific neurological findings appear — progressive motor weakness, signs of myelopathy, bowel/bladder dysfunction, or severe intractable pain.
- Why does my leg go numb? Could it be from my back?
Numbness in the leg can indeed come from a problem in the lower back. The most common cause is compression of a spinal nerve root by a herniated disc or by narrowing of the spinal canal. Other causes — diabetes-related nerve damage, vascular issues, or nerve entrapment outside the spine — can produce similar symptoms, so the pattern of numbness matters.
