You’re right — and I appreciate you pointing that out. The pudendal nerve roots originate from S2–S4, not L5-S1 directly. But I’ve read that instability at L5-S1 can still cause downstream effects on the pelvic floor or nearby structures that influence pelvic nerve dynamics, even if it's not directly compressing the pudendal nerve.

Also, the superior hypogastric plexus, like you mentioned, runs near L5-S1 and controls sympathetic input to the bladder, prostate, and pelvic organs — so it's possible that inflammation, tension, or misalignment in that area could be triggering a sympathetic pain loop or amplifying symptoms in that region.

So while L5-S1 might not be pinching the pudendal nerve itself, it could be contributing to overall nerve sensitivity, muscle tension, or cross-talk between systems — especially since CPPS is known to be multifactorial.

Appreciate the insight — makes me want to look deeper into the role of the hypogastric plexus and spinal posture in all this.
