Revision
I think it would be much easier to change meds than to go thru another surgery. I think most of us here agree that WLS doesn't improve our fibro so there's no guarantee that a revision would change anything. Also Celebrex is an Nsaid which I thought RNY folks were supposed to stay away from also it's more for arthritis pain than fibro pain. There are 3 drugs primarily for fibro Lyrica, Cymbalta and Savella. Some of us also have to use narcotics to get relief. So I would try some different meds rather than try to revise. Good luck to you!
