Oh dear.
I could jump to several conclusions and none of them are good.
My mom's best friend had fibroids removed that were the size of watermelons.
Intestinal problems, ovary/uterine problems, bladder problems, cancer, infection, parasites - the list goes on and on.
I'm sorry you've had such bad experiences with medical professionals but if you can't work with any I'm not seeing how you can have any hope of improvement in your situation.
I'd rather work with a doctor than an undertaker.
Perhaps you could find a chronic pain support group or a hospice to help you.
Good luck to you and I hope your suffering is resolved soon preferably with you surviving.
