I have this same thing going on with swelling in the right side of my stomach. Have for about 5 years now. Always feeling like I have to take a dookie, and when I do I feel better. However I also feel like I have to eat right after the dookie. It's a cycle that doesn't end.

I had giardia when I was about 19 (now 27), I think there is a chance it never fully went away. I also drink lots of carbonated drinks, and few vegetables. I probably should fix that, it gets annoying to deal with this every day, I feel your pain.

I can physically push on the right side of my stomach, right next to my belly button, and feel my swollen intestines and move them around hearing the gas move. Also have a hairless spot there where the rest of my stomach and chest have hair. Not sure if that is related to it or not, as I also appendix carry my concealed weapon and it rubs there all the time.

Maybe too much info, but just know you're not a lone.
