The Co2 can be more overwhelming then the surgery its self it usually goes up the the right shoulder tip and is recommended that you sleep at a 30 degree elevation to help with the discomfort. A warm blanket on the abdomin may help and don't dispair it will resolve it just takes time.
I am so sorry to hear about your extreme pain. My heart goes out to you. Please forgive my tardy response. I have having some major computer problems.
Although you are always welcome at the Pain Management Forum you post may receive more responses in a forum more appropriate to your problem and concerns. Our focus is more on long erm chronic pain. So because I want you to receive the best available information I am requesting that your post be evaluated by our astute Moderators for a possible move to a more appropriate forum.
What I can suggest is that you contact your physician/surgeon. I think you require medical attention/evaluation as soon as possible.
Best of Luck to You,
