Pain that shoots from the low back down the leg usually means a nerve root is irritated. Most cases improve without surgery — the work is managing the weeks in between.
"Sciatica" is the everyday word for lumbar radiculopathy: a nerve root in the low back is compressed or inflamed, most often by a disc herniation or a bone spur, and the pain travels along that nerve — buttock, thigh, calf, sometimes into the foot. Tingling, numbness, or mild weakness can come with it. The leg is where it hurts; the back is where the problem lives.
The pattern of your pain and a focused neurologic exam — strength, sensation, reflexes, nerve tension tests — usually point to the culprit nerve root. MRI confirms it when the story and exam call for imaging, or when an injection or surgery is being considered. We read your images with you, side by side.
If any of these apply, go to an emergency department or call 911 rather than waiting for a clinic appointment.
Most radiculopathy improves within weeks. Early care is active: keep moving within pain limits, targeted physical therapy, short courses of anti-inflammatory medication when appropriate, and time. Bed rest beyond a day or two makes things worse, not better.
When leg pain is severe or stalls out despite good conservative care, an epidural steroid injection can calm the inflamed nerve root so you can move and rehab — it treats the pain, not the disc. A selective nerve block sometimes doubles as a diagnostic tool when the source is unclear.
Surgery is the right conversation when there is progressive weakness, when red-flag signs appear, or when disabling leg pain persists for months despite everything above and imaging shows a clear surgical target. When that's your situation, we say so plainly and refer you to a spine surgeon — keeping you in injections you don't need helps no one.
