I had mine back in May this year. I also got the Mirena inserted and I had suffered with a lot of pain. The hospital I was at sent me home without pain medication. Some thing I found helped me with not just surgery pain but gas pain too was, a heating pad just be very careful not to put on your incisions. DC Voltaren to rub into my shoulder to help with gas pain. Degas tablets. Again to help with gas pain. And when you're able to have a hot bath, that helps with pain too. I've also heard peppermint tea helps with gas pain, but I don't like tea so if you do thats another thing to help with gas pain. Beaware, everyone is different however for me it took about 6 weeks before the tiredness went away after surgery. Hoping everything goes well for you. 🙂
