Condition
Sciatica
Sciatica describes pain that follows the course of the sciatic nerve into the buttock and leg, but it does not by itself tell you the cause. Atlas can help explain why disc herniation, stenosis, or other lumbar nerve problems produce this pattern and how Dr. Iyer matches treatment to the underlying source.
What sciatica is
Sciatica is a symptom pattern caused by irritation of one or more lower lumbar or sacral nerve roots that contribute to the sciatic nerve. It is not a stand-alone disease, which is why the evaluation focuses on what is compressing or inflaming the nerve.
What it feels like
Patients often describe sharp, burning, electric, or aching pain that starts in the low back or buttock and travels down the back or side of the leg. Numbness, tingling, calf weakness, or foot weakness may appear depending on the nerve root involved.
What usually causes it
The most common causes are lumbar disc herniation and spinal stenosis, though spondylolisthesis or less common structural problems can also irritate the nerve. The timing of symptoms, the distance the pain travels, and the neurologic exam help narrow the source.
How it is treated
Treatment depends on the cause and severity, but many patients start with medication, therapy, and time while the irritated nerve settles down. Persistent disabling pain or progressive weakness can lead to more targeted imaging, injections, or surgery such as microdiscectomy or decompression.
