What does endometriosis feel like? ? ?

I had an ovarian cyst rupture a couple months ago and have been having real dull but achy pain in my pelvic area, especially to the right side, it’s not overly severe but it’s very noticeable and irritable and sometimes can shoot down my leg. 

I have had another large cyst come and go but the ultrasounds now are only revealing mild poly-cystic ovarian syndrome which I’m told should not be causing pain.I am going for a test for endometriosis which is costing me heaps, but I just want to know if this pain is typical because I am not overly convinced I have it but nothing else seems to be wrong
