I can’t believe they waited so long and you haven’t been given the option of an RNY revision. Everything you’ve said sounds like be minus the extra surgeries and time. I’ve had GERD pretty bad for the last 5 months (Pepcid and protonix with tums) and a new hiatal hernia (had one repaired with my sleeve in December 2019) and my revision surgery is in 9 days. I definitely think you need a second opinion for sure!
Sorry you’re in so much pain. I really hope you get answers soon!
