Hey there... Well I was like you with that whole thing. I have had severe chronic pain around my ovaries. I was sent to a specialist and he also said I had IBS which yes it is a possiblitie as your bowels surround everything very tightly as I was told but with having the cyst rupture I would be worried maybe you have endometriosis. Have they tried looking into that? That is where all my pain is for the most part and it took a pelvic ultrasound to even get noticed somthing was wrong then they tied my tubes and did a LAP to explore everything very closely. Come to find out I had stage 4 endometriosis which yes it is very painfull and can attach to ovaries and your tubes and other organs maybe bring that up to your GYN and see waht they think of that option to look more closely that is the only way I was diagonosed with my condition.
Hope this help if you wanna talk more about this let me know Im very happy to help out
