Hi Hurting Girl and welcome to the Forum.
Sorry that you are in such pain, especially with a baby too. I have bumped this post so that others who have had LIS will notice the post and reply to you. I also gave you a post of 'your own', moving your post.
You will find also that there is a lot of information on here, so do use the Search box at the top right of the page, and you will find all sorts of things there.
A lot of people have had LIS and come well through it. I see you said that a general surgeon has seen you through this. Will a colon and rectal surgeon be doing the actual surgery? They are really the ones fully experienced in all things bum!
Don't be scared. You join many others on here who have sailed through this surgery. Thinking of you. Big
