Hia! I'm so pleased you're having a lap. You'll feel like a new woman after. I had mine in dec, and have had a previous csection. They found a load of scar tissue adhesions in me from my section where my uterus had fused to my bowel, as well as a boat load of Endo too. When I woke up from surgery they'd snipped the adhesions and excised the Endo, and whilst I felt a little sore from the incisions i was in much less pain than before. I didn't realise just how much pain I had been in. it was the best thing I have had done, and I really hope you have a similar experience. Would do it again in a heartbeat! My kids were 6&8 when I had it done so a little older than yours. After two weeks I was feeling much better although tired and after three weeks I really did feel like I was over the op. I would say for the first three to four days make sure you've got an adult there to help you. There was a lot of pain in my shoulders after the op, in fact that pain was probably worse than the pain for the actual operation. I recommend drinking peppermint tea or peppermint cordial to try to displace that. But after 3/4 days that had gone.
Other than that i'd just recommend getting as much sleep and rest as possible. i found a direct correlation between the amount of rest I got and the reduction in my pain levels. Good luck! Xx
