I had my Lap done today, internal U/S and bloodwork showed nothing unusual however I had 3 areas of endo removed and a sizeable adhesion removed as well. Considering they took about 2 hrs, I am in minimal pain and only discomfort when moving around. Not even any shoulder tip pain really, remember with that to stay elevated and not lie flat as that encourages left over gas to push the diaphragm and cause the pain.
I have an FS attached to IVF and I feel its much more comprehensive in investigating issues and without the Lap, I would never have known about these issues hindering my ability to conceive.
Good luck and I hope its a quick and painless journey for you.
