I had a laparoscopy - findings - bowel very swollen and bloated and ovary attached to bowel with scar tissue. could this have been causing my pain?

Very possible: This certainly could have been causing your abd pain. If the adhesion(scaring) was corrected at the time of the laparoscopy, then you will have the answer in about 4 weeks after the laparoscopy.

Absolutely: the findings are a pathology that definitely could cause abdominal pain i am very confident that your pain will decrease after surgery
