I have had Crohn's for 30 years and have had your symtoms on occassion. What works best for me is Beano (it's natural) and Zantac. I think sometimes people over pathologize because they have CD and don't realize they might be experiencing, dare I say it, symptoms similar to constipation (which by the way is a symptom of the same animal we all have). I also suggest laying off of all cheap cheeses (pizza, etc.). Aged cheese is fine because it contains no lactase. Yogurt is great because of acidophilus (good for the gut). No fried anything. No alcohol. No cigarettes (believe it or not it loosens the bowels). Carbonated beverages have been known to cause havoc for many (even that fizzy water stuff).
In my experience, it may be good to keep nagging your doc until you feel better....or find a new doc. Recently, I've started to think that vitamin D deficiency is a culprit for many of us and while supplements are convienent, maybe being outside, even in the shade, is a better source. I get
accupuncture from my chiropractor because then my insurance pays for it and it helps with my whole body which I am convinced is connected to my overall good health.
I hope something I said is of use to you. Peace out.
DX Crohn's Disease 30+ years ago; re-diagnosed with Microscopic Colinitis when scan was clear (so ridiculous) Take 3-6mg of Endocort. Have taken predisone, sufa drugs and asacol in the past. One doctor had me on Perigoric (an opiate. Didn't help the CD, but I didn't care). Present doc told me to start smoking marijuana...I don't because I don't like it, but there is research confirming results.
