Hi- I had to have a mini laparotomy done about a year after my hyster because of pelvic pain. Now let me say up front that I had the total hyster due to stage IV endometriosis so I had 4 open surgeries before the hyster. My pain and cramping mostly came (sorry if TMI)on shortly before I needed to have a bowel movement ora meal my tummy didn't agree with so I was 90% sure that the tugging/cramping type feeling I had were adhesions stuck to my bowel so my pain was on my left lower side. If your'e not familiar with what they are do a simple google search and look at pics. They are very common anytime you have had a previous pelvic surgery. It's like cobweb glue, your bodies own way of protecting itself when something foreign was in there and it sounded like you kept your ovaries so they can attatch to them n tug n pull which for me was painful. Unfortunatly the only way a GYN can see them is with a scope (exploratory laparoscopy) and then they just simply cut them free. It is an out patient surgery and recovery time less than a week 3-4 days tops. They can also put a film through the scope to prevent new adhesions. Hope I helped and if thats what it is, easy fix. Good luck!
