For most people, sciatica starts with a bulging disc in your lower back. The disc pinches the sciatic nerve.
When that happens, the muscles around the nerve tighten up to protect it.
This happens in your lower back, hips, buttocks, and legs.
But here’s the problem…
Your sciatic nerve runs between these muscles. When they tighten up, the nerve gets squeezed between them.
So every time you move, sit, or bend, those tight muscles compress the nerve even more. And that burning, shooting pain feels worse.
Until you release those tight muscles, the pain often stays.
