I've had piriformis syndrome and a catastrophic lumbar disc blowout. It can be hard to tell the difference, but the disc was 100x worse and left me with noticeable muscle atrophy.
I’ve had some weird stuff with my SI joint on the same leg- x-rays look like soap bubbles on it and have had CT scans that point to a benign process. It could have something to do with it, but this is deeper, almost in my hip and only with certain motions.
