Hi C.! I feel your pain! After 5 laporascopies and finally a hysterectomy I feel like I am somewhat of an expert for these procedures. HA! As the other ladies stated, the pain is from the gas they blow you up with. I had it with all of my procedures. Don't lie down flat. The more you can get up and move around the better. Of course it won't feel like it's better. Just don't over do it. None of the GasX stuff ever worked for me, but it's worth a shot. Maybe it will help you.
Your stitches will probably fall out on their own. Usually within a couple of weeks. They'll start itching like crazy. I just kept Neosporin on it every now and then. If it starts getting red or hurting go see your doc. It might be an infection.
Good luck with everything and be sure and get some rest!!!
