Hi cmommy! I had my only resection over 20 years ago, but I still remember the bloat. Patience is a virtue in this case. It will settle down. Can you lie down on a hot pad for your shoulder? That helped me when I had the pressure problems.
As for the D, I also am on cholestyramine. I had 18" of my terminal ileum removed, then later my gallbladder. I have had D constantly since until I went back on the cholestyramine. The doc can prescribe generic or you can get name brands. I am trying to get back on the Prevalite version--it has artificial sweetener so some are leary of it but I have found it mixes better in my juice and it seems to work better for me. Talk to your doc about it. It made me have a much more normal life!
