The sciatic nerve is the biggest and longest nerve in the human body. In reality, the “nerve” is not a single nerve. It’s actually made up of 5 nerve roots that cluster in the lumbar spine and sacrum. From the base of the spine, the sciatic nerve travels down the buttock, back of the thigh, calf, heel and sole of the foot on each side of the body.
The sciatic nerve is responsible for a large number of motor functions and sensations in the lower extremities. Among other functions, it controls muscular movement for pointing the feet and toes upward and downward, bending the knee and hip abduction. Additionally, the sciatic nerve supplies sensation to the skin of most of the lower legs and feet.
The sciatic nerve is also responsible for causing a painful set of symptoms known as sciatica. It’s estimated that between 10-40% of the population has experienced sciatic pain. Keep reading to learn more.
Sciatica describes a type of nerve pain that occurs when the sciatic nerve is compressed or inflamed. Sciatica is not a condition; rather, it’s a symptom of different conditions that cause compression, narrowing and inflammation in the spine. Sciatic pain is often a symptom of the following spinal conditions:
In addition to the causes listed above, a traumatic incident like a car accident or sports collision can directly damage the sciatic nerve, causing pain and inflammation.
The defining characteristic of sciatica is one-sided pain that radiates from the low back to the buttock, thigh and calf. The pain may feel sharp, deep and aching, or burning. It may be aggravated by certain movements, like sitting for long periods of time, coughing or sneezing. For some people, sciatica is painful but doesn’t affect their ability to perform daily activities. For others, the pain is severe enough to make walking, standing or sitting difficult.
Other symptoms you may experience are weakness, muscle spasms, cramping, numbness and tingling in the leg and foot. Sciatic pain and symptoms can occur anywhere along the path of the nerve.
In many cases, sciatica is an acute condition that resolves within a few weeks using at-home care measures. Your doctor may advise you to use hot and cold compresses and take an over-the-counter pain medication to help ease pain and inflammation. Additionally, your doctor may recommend specific stretches and exercises to relieve muscle tension and pressure in the low back. While many people are tempted to rest frequently when they have pain, try to remain as active as possible while you’re healing. Sitting and being immobile for long periods will worsen sciatic pain, inflammation and other symptoms.
If you continue to experience pain after several weeks, your doctor may prescribe stronger pain medications, muscle relaxants or a corticosteroid injection. Corticosteroid injections only provide temporary relief, but they buy you time to build up your strength and regain normal mobility. Your doctor may also recommend a course of physical therapy. A physical therapist can help you find exercises that relieve pressure on the sciatic nerve. Additionally, a therapist can work with you to increase strength in your core, low back and legs — the key muscles that protect and support your spine.
When conservative measures aren’t effective, it’s time to consider surgery. At this point, your doctor will probably take imaging exams to determine if a herniated disc, bone spur, arthritis or another injury is the source of your sciatic pain.
