I'm 4 week post op and it was the same for me. I tried cold,warm and hot water and still pain so I stopped drinking reg water. I was able to drink vitamin water. I tried again 2 days ago and no more pain
I'm now 8 days post op and it takes me all day to get a water bottle size of protein shake in. The gas pain stated getting better about day 5-6. And I had my first bm day 6 and has since turned into diarrhea. Here at my clinic were on clear fluids for the first 2 weeks.
