Is pelvic floor dysfunction IBS real?

If so, what are the symptoms, and how is it fixed.

I’ve been diagnosed with pelvic floor dysfunction, but what confuses me is high fodmap foods trigger my ibs. Does fixing the pelvic floor dysfunction get rid of food triggers?

If I think back to when my whole problem started, I started getting horrible flares when I’d eat high fodmap. My theory is I developed pelvic floor dysfunction with all the straining I did on the toilet, due to having ibs-c. I’m not sure if I want to waste months on pelvic floor therapy just for it to not be the cure, and then I’m back to square one, but I’m out thousands of dollars.
