Is doing body squats helping or hurting my herniated disk. I'm trying to fix myself?

Depends. Having an imaging study showing a disc herniation does not mean that the said herniation is causing symptoms. The significance could be determined by a thorough history and physical examination. Simple squats in isolation would not be optimal for maintaining a healthy back. Rather, exercises geared towards maintaining flexibility and strenghtening core back and abdominal muscles should be the goal.
Hurting. Incresing disc pressure with squats squats have caused disc herniation seems like a poor choice irritated nerve respond best to rest use pain ad your guide you can heal on your own but im not sure anybody can fix themselves.
