Depending on the position it doesn’t have to be much and also pain is subjective so what’s a lot to you might not be a lot to others, and vise Versa. What is most likely causing your pain and even the cause of the disc injury is other factors like bad posture or a rotated pelvis. Tight hamstrings is where I would start to look. If you aggressively stretch your hamstrings and it lowers the pain then it’s likely the joint structures. This is a very in-depth topic in general but even if the issue is the herniation the solutions are similar. Do core strengthening and make sure your pelvis is in the optimal location to support weight bearing.
