Piriformis syndrome vs sciatica is a question I hear all the time. Here is the honest answer. Most sciatica starts in the low back. But sometimes the piriformis is the culprit. Here is how to tell the difference.
What sciatica actually is
Sciatica means the sciatic nerve is irritated. You feel it as pain, tingling, or numbness running down the leg. The name describes the symptom, not the cause.
Most of the time, the irritation starts in the low back. A disc presses on the nerve root. A stiff spinal segment changes how the nerve moves. That is the honest frame, and it matters. Treating the butt for a back problem wastes your time.
When the piriformis is the culprit
The sciatic nerve runs right under the piriformis, a small deep muscle in the buttock. In about 10 to 15 percent of people, part of the nerve pierces straight through the muscle instead. Those people are the most likely to get true piriformis syndrome.
The piriformis version has a specific feel. The ache lives deep in the butt. Sitting feels like you are parked on a rock. Pigeon pose feels impossible. The pain stays local or runs down the back of the thigh, but it starts in the butt, not the back.
Does sitting feel like you are parked on a rock? Does pigeon pose feel impossible? That is the piriformis talking.
How to tell the difference
Ask where it starts. Pain that starts in the low back and shoots down the leg points to the back. Get the back checked first.
Ache that lives deep in the buttock and hates sitting points to the piriformis. It gets worse the longer you sit. It eases when you stand and move.
A tight piriformis chokes the nerve and stiffens the hip. It limits rotation, which is why pigeon and figure four feel so out of reach. Free it, and stride and sitting get easy again.
New, severe, or worsening symptoms deserve an in-person check. Numbness that spreads, weakness in the foot, or pain that keeps you up at night are not DIY territory.
The release
Sit on the ball first. Right in the meaty part of the buttock. The bullseye of your butt cheek. Melt, then breathe.
You will know it when you are on it. If you are not sure, you are not on it. That is the rule. The piriformis hides under the big glute muscles, so sink in slow and let the tissue come to you.
Figure four opens the space to sink deeper. Cross the ankle over the opposite knee and lean in. It can be too intense, so feel it out. Back off the moment it turns sharp.
Gentle only. Let your body weight do the work, never force it. Keep the ball on the muscle, off the sit bone and tailbone. Stop right away for sharp pain, numbness or tingling shooting down the leg, or pain that lingers and worsens the next day. Sit this one out with a fresh hip or low back injury. This is for the chronically tight, not the newly hurt.

This release is from my Hips class, one of seven in the Myofascial Release Bundle. The class works the whole hip system, so the piriformis stops choking the nerve and stiffening the joint. Let me know if you need the link!
