What It Is
Sciatica is the name for pain, tingling, numbness, or weakness that travels along the sciatic nerve — usually starting in the low back or buttock and running down the back of the leg, sometimes all the way into the foot.
Here's the part most people miss: sciatica isn't a diagnosis. It's a description of what you're feeling. Something is irritating or compressing the nerve, and the leg pain is the result. The real question — the one that determines whether treatment works — is what's causing it.
