Lisa,
I was banded last Tuesday as well! I am sorry to hear you have had so much pain. I actually called my Dr. office to see if I was normal since I did not have the gas pain I had so dreaded! I have 2 friends who were banded yesterday and both of them were in extreme pain. My nurses all stressed "walking and drinking plenty of water" and I did that. Don't know if that is the difference or not since these ladies woke up from surgery in pain and I did not. I actually felt good enough today that I drove to my daughters house about 30 mins. away. Of course, it tired me out, but didn't make me hurt.
Try moving around as much as you can and drink plenty of Water. I hope you are better soon. Have you called your Dr. office to seek advice? Mine are awesome and very helpful.
If the pain seems to be gas you might want to try some GasX. I had bought 2 boxes thinking I would need them and they are not even opened.
Good luck,
Nancy
