Lumbar radiculopathy is a condition that happens when a nerve in the lower back (lumbar spine) becomes irritated or compressed. These nerves branch out from the spinal cord and travel down into the legs, so when one is affected, it can cause pain, numbness, or tingling that spreads from the lower back into the buttock, thigh, or even down to the foot. Many people know this condition by the more familiar term “sciatica,” although sciatica usually refers specifically to irritation of the sciatic nerve.
The most common causes of lumbar radiculopathy are problems that put pressure on the spinal nerves. These include a herniated disc (when the soft cushion between the bones of the spine slips out of place), spinal stenosis (narrowing of the spaces where nerves travel). Sometimes, an injury or repetitive strain can also trigger the condition. Risk increases with age, heavy lifting, or activities that put stress on the lower back such as deadlifting.
Symptoms often include shooting or electric shock-like pain that travels down one leg, muscle weakness, numbness, or a “pins and needles” feeling. The pain can range from mild to very severe and may get worse with certain activities like sitting, bending, or coughing. Some people also notice difficulty moving their foot or toes if the nerve compression is significant. In most cases, the problem affects one side of the body, but it can occasionally impact both.
Treatment depends on the cause and severity. Many people improve with rest, gentle stretching, physical therapy, or medications that reduce inflammation and nerve pain. In some cases, epidural steroid injections can help calm irritated nerves. Surgery can be considered if symptoms don’t improve with other treatments, or if there is weakness or numbness. Most people recover well, especially with early care and activity modifications, and many can return to their usual routines with the right treatment plan.
