What to Do Next If a sharp, shooting pain has been running from your lower back down one leg, you may already suspect it is sciatica, but you probably still have questions about why it is happening and what actually helps. Understanding sciatica symptoms and treatment can take a lot of the guesswork out of a condition that is common, disruptive, and very treatable once the underlying cause is identified. This guide walks you through what sciatica is, what causes it, and what your treatment options look like from evaluation to relief. 1. What Is Sciatica? Sciatica refers to pain that travels along the path of the sciatic nerve, which runs from your lower back through your hips and buttocks and down each leg. It is the longest and largest nerve in your body, which is why irritation or compression anywhere along its path can cause pain that radiates well beyond your lower back. According to MedlinePlus, a service of the National Library of Medicine, sciatica is a symptom of an underlying problem rather than a medical condition on its own, which is why identifying the actual source of the compression matters so much for effective treatment. Sciatica usually affects one side of your body at a time. Symptoms can range from a mild ache to pain severe enough to make standing or walking difficult, and they often worsen with sitting, bending, twisting, or coughing. 2. What Causes Sciatica Sciatica develops when a structure in your lower spine puts pressure on the sciatic nerve root. Understanding sciatica symptoms and treatment starts with knowing exactly what is causing that pressure in the first place. According to the National Institutes of Health, the most common cause is a herniated or bulging disc pressing against the nerve, though several other conditions can produce the same result. Common causes include: Herniated or bulging discs in the lumbar spine Spinal stenosis, or narrowing of the spinal canal Degenerative disc disease Spondylolisthesis, where one vertebra slips out of place Piriformis syndrome, where a muscle in the buttock irritates the nerve Injury or trauma affecting the lower spine Identifying which of these is actually causing your symptoms is the difference between a treatment plan that provides lasting relief and one that only addresses the pain temporarily. 3. Common Symptoms to Watch For Sciatica pain has a distinct pattern that sets it apart from general lower back pain. Symptoms typically include: Pain radiating from your lower back through your buttock and down one leg A burning, aching, or sharp shooting sensation along the path of the nerve Numbness or tingling in your leg or foot Muscle weakness in the affected leg Pain that worsens with prolonged sitting, standing, coughing, or sneezing Symptoms that stay confined to your lower back without radiating into your leg are less likely to be sciatica and more likely to be a different type of back pain. Recognizing sciatica symptoms and treatment options together helps you understand when home care is enough and when it is time to bring in a specialist. Our guide on when to see a doctor for pain can help you figure out whether your symptoms warrant an evaluation regardless of which category they fall into. 4. The Diagnostic Step That Comes Before Treatment Before recommending any treatment, your provider needs to confirm that your symptoms are actually sciatica and identify the specific structure causing the nerve compression. This typically includes a detailed history of your symptoms, a physical examination assessing your reflexes, strength, and range of motion, and imaging when needed to visualize the affected area of your spine. Skipping this step and treating the pain generally, rather than the specific cause, is one of the most common reasons sciatica treatment fails to provide lasting results. A precise diagnosis is what allows your provider to target treatment at the actual source of the compression instead of just the symptoms it produces. 5. Sciatica Symptoms and Treatment: What Are Your Options? Most cases of sciatica improve with a combination of conservative and interventional approaches, tailored to the underlying cause and severity of your symptoms. Physical therapy. Targeted exercises and stretches help relieve pressure on the nerve and strengthen the muscles that support your spine. Anti-inflammatory medication. Reducing inflammation around the affected nerve root can ease pain during the early stages of treatment. Epidural steroid injections. Medication delivered directly to the space around the irritated nerve root can significantly reduce inflammation and pain. Nerve blocks. A targeted injection interrupts pain signals traveling along the affected nerve, providing both diagnostic information and symptom relief. Radiofrequency ablation. For cases involving facet joint irritation contributing to nerve compression, this procedure uses targeted heat to disrupt pain signals. Surgery is typically reserved for cases that do not respond to conservative and interventional treatment, or for symptoms involving significant weakness or loss of bladder or bowel control, which require immediate medical attention. If you want a broader look at how interventional approaches work across pain conditions, our guide on what interventional pain management is and how it works covers the full range of procedures in more detail. 6. When Sciatica Needs More Than Home Care Mild sciatica often improves within a few weeks with rest, gentle movement, and over-the-counter medication. Certain signs, however, suggest it is time to move beyond home care and schedule a proper evaluation: Pain that has lasted longer than four to six weeks without improvement Numbness, tingling, or weakness that is worsening rather than improving Pain severe enough to interfere with sleep, work, or daily activities Difficulty controlling your bladder or bowel, which requires immediate medical attention Sudden, significant weakness
