Sciatica is a common type of nerve-related pain that starts in the lower back or buttock and travels down the leg. For some people, it feels like a sharp, shooting pain. For others, it may feel like burning, tingling, numbness, or weakness that makes sitting, standing, walking, bending, or sleeping uncomfortable.
Although many people describe sciatica as a condition, it is actually a set of symptoms caused by irritation or compression of the nerve roots that form the sciatic nerve. This nerve begins in the lower spine, travels through the hips and buttocks, and continues down each leg. When one of these nerve roots becomes irritated, pain can radiate along that pathway.
Sciatica often affects only one side of the body. The pain may stay in the buttock or thigh, or it may travel below the knee into the calf, foot, or toes. Because sciatica can come from different spinal or soft tissue problems, understanding the root cause is an important first step toward finding the right treatment approach.
Sciatica most often develops when a nerve root in the lower back becomes compressed or inflamed. One of the most common causes is a herniated disc, sometimes called a slipped or bulging disc. When disc material presses on a nearby nerve root, it can trigger pain, numbness, tingling, or weakness that travels into the leg.
Other possible causes include spinal stenosis, which is a narrowing of the spaces around the spinal nerves, or bone spurs related to arthritis and age-related spinal changes. In some cases, inflammation, muscle tightness, poor posture, repetitive lifting, prolonged sitting, or an injury can contribute to sciatic nerve irritation.
Sciatica symptoms can vary from mild discomfort to severe pain. Common symptoms include:
Not every case of leg pain is sciatica. Hip problems, muscle strains, sacroiliac joint irritation, peripheral neuropathy, and other conditions can cause similar symptoms. That is why a professional evaluation is important, especially when symptoms are persistent, worsening, or interfering with daily life.
Sciatica can happen for many reasons, but several factors may increase the likelihood of developing sciatic nerve pain.
A herniated disc in the lower back can press on a nerve root and cause pain that radiates down the leg. This is one of the most common reasons people experience sciatica symptoms.
Spinal stenosis occurs when the spaces in the spine narrow and place pressure on the nerves. This can cause leg pain, numbness, or weakness that may worsen with standing or walking.
As spinal discs age, they can lose height and hydration. These changes may affect spinal alignment and increase stress on nearby joints, discs, and nerves.
Sitting for long periods, slouching, or using poor lifting mechanics may increase stress on the lower back and contribute to nerve irritation.
Tight hip muscles, weak core support, limited spinal mobility, or uneven movement patterns can increase strain on the lower back and pelvis.
A fall, sports injury, car accident, or repetitive bending and lifting can irritate the lower back structures that surround the sciatic nerve roots.
A sciatica evaluation usually begins with a health history and physical exam. Your provider may ask where the pain travels, what movements make it worse, and whether you have numbness, tingling, or weakness.
During the exam, your provider may assess posture, spinal mobility, muscle strength, reflexes, sensation, and movement patterns. Certain orthopedic or neurological tests may help identify whether a lumbar nerve root is irritated.
Imaging is not always needed right away, especially for mild symptoms. However, X-rays, MRI, or other testing may be recommended if symptoms are severe, do not improve, follow a major injury, or suggest possible nerve compression or another serious condition.
You should consider a professional evaluation if sciatic nerve pain lasts more than a few days, keeps coming back, limits daily activities, or causes pain that travels below the knee.
Seek urgent medical care if you experience:
These symptoms may point to a more serious problem that requires immediate medical attention.
Chiropractic care for sciatica focuses on identifying mechanical stress, movement limitations, posture problems, and soft tissue factors that may contribute to nerve irritation. Because sciatica can have different causes, care should always begin with a thorough evaluation.
At Vital Roots Chiropractic, care may include gentle chiropractic adjustments, spinal mobility work, posture assessment, movement guidance, soft tissue support, and personalized recommendations to help reduce irritation and improve function. The goal is not to simply chase symptoms, but to understand what may be contributing to the pain.
For some patients, chiropractic care may help improve mobility, decrease mechanical stress on the lower back, and support better movement patterns. If symptoms suggest a condition that requires medical imaging, specialist care, or emergency evaluation, an appropriate referral may be recommended.
Sciatica often feels like sharp, shooting, burning, or electric-like pain that starts in the lower back or buttock and travels down one leg. Some people also experience tingling, numbness, or weakness in the leg, foot, or toes.
Chiropractic care may help some patients with sciatica by improving spinal mobility, reducing mechanical stress, and supporting healthier movement patterns. A proper evaluation is important because treatment depends on the cause of the nerve irritation.
Leg pain may be sciatica if it starts in the lower back or buttock and travels down the back of the thigh, calf, or foot. Numbness, tingling, burning, or weakness can also occur. A professional exam can help confirm the source of symptoms.
You should seek urgent care if sciatica is accompanied by new leg weakness, loss of bowel or bladder control, numbness in the groin area, fever, unexplained weight loss, or severe pain after trauma.
