Hi Quiggles,
Sorry you are experiencing pain and discomfort, but happy for you that it's all over, and you will soon be feeling much better.
I have not had surgery, but there are many here who have, and hopefully hopetoheal might come on with info about here successful LIS, and there are many others here who have experienced the pain and discomfort that go with the first week after the surgery.
I can suggest is that you look up some of the 'oldies' reports under the same link that you have posted your message.
Hope you will feel better very soon. Hope you are drinking lots of water, using Miralax, and pampering yourself and your rear. Also, if you don't feel happy about the pain you're experiencing, the best person to speak to is the doctor who did your op.
Wish you better soon
