I too had severe back/side pain during the first week post op. I had my 6 week f/u, 1st fill this past Friday Feb 13 and the back pain came back last night (Tues) where i thought i had to go to the ER. After the heating pad not working, it never did in the beginning either, i got down 2 advil and put on an ice pack. The ice seemed to do the trick...enough for me to sleep 1 hr. It's better but still there. It's really annoying and i'm thinking maybe i ate something wrong to cause this. Anyone else have this happen? It's funny that i don't even have any pain where i thought i should...on my front side! :blushing:
