Agree with the Home Health suggestion. You can also get a memory foam mattress that goes on your bed from Cdn Tire.
Other ideas: there is a Manitoba Pelvic Pain facebook page to think about joining.

Has she ever tried medical cannabis - in particular, making your own suppositories. They help!
She could think about having a laparoscopic surgery done to see if anything is going on with cysts, endometriomas, endometriosis, adenomyosis, PCOS, fibroids, etc. There is a Ob/Gyn in Winnipeg Dr Anet Maksymowicz who is Manitoba's only Dr trained in lapraroscopic endo excision surgery. She could also look to see if it is pelvic nerve entrapment, and if it is - Dr Lemos in Toronto is the next step.
Good luck, chronic pain is terrible.
