I'm so sorry you're going through this. I know how horribly painful endo is. I'm puzzled with your symptoms. Endo can travel anywhere so I suppose it's very possible for it to cause the pain and burning in the areas you are. I had it EVERYWHERE! My last ( and best ) surgeon drew a picture for me with x's on the areas I had it and they were covering almost the entire area! I was in the last stage ( before everything just freezes and sticks together ). What did your doctor tell you after your lap? Yes, I'm confused why they didn't go ahead and remove the tissue while they were doing the procedure. That's pretty standard protocol here. If I were you, I would insist on some tests to find out for sure why you are having this burning. Seems to me it could be caused by anything. I hope you get some answers and relief soon. :-)
