How Sciatica Is Diagnosed: Tests and Imaging Explained

Leg pain, tingling, or weakness in the lower back can often be traced to sciatica. At Reno Tahoe Pain Associates in Reno, NV, Dr. Ali Nairizi, Dr. Nicholas Carlevato, and Dr. Andrew Wesely specialize in evaluating nerve-related pain and helping patients find relief through precise diagnosis and targeted treatment.

What Is Sciatica and What Causes It

Sciatica is pain caused by compression or inflammation of the sciatic nerve, which runs from the lower back down each leg. The symptoms typically involve sudden, stabbing pain down into the buttock or leg, numbness, tingling, or leg muscle weakness. It is typically caused by underlying spinal disease, such as a herniated disk, spinal stenosis, or bone spurs compressing on the nerve.

First Assessment by a Pain Specialist

A thorough clinical evaluation is the first step when you present at Reno Tahoe Pain Associates with sciatica symptoms. You'll have a consultation with a pain specialist about your symptoms, your medical history, and a physical examination will be conducted. The straight leg raise may form part of this, with a slow and gentle lifting of your leg to see if you experience pain with movement of the sciatic nerve. This is utilized to decide if symptoms are typical of nerve irritation.

Imaging Tests That Confirm Sciatica

When a physical exam reveals sciatica, imaging tests may be ordered to establish the etiology of the nerve compression. X-rays may show bone alignment or structural alterations, but MRI usually outlines soft tissue and nerve roots most clearly. A CT scan can also be employed, especially if an MRI is unavailable. Diagnostic tests validate a patient's diagnosis and rule out other possibly dangerous disorders, such as a tumor or infection, as the etiology of sciatica.

Why Accurate Diagnosis Matters

Pinpointing the cause of sciatica allows your pain management team to develop a plan that addresses both symptoms and the underlying issue. An early and accurate diagnosis can reduce unnecessary treatments, improve outcomes, and help patients return to daily activities with less pain. At Reno Tahoe Pain Associates, patients benefit from expert evaluation, advanced diagnostic tools, and a range of personalized treatment options.
