Bloating amd digestive issue. Reports.

I'm suffering from digestive issues for past 1 year. I have done colonoscopy twice last year. At first, colonoscopy and biopsy was consistent with Ulcerative Colitis. Later after 10 days, another colonoscopy has been done. There were no ulcers and moderate inflammation present in distal rectum. Biopsy suggested non specific colitis and not UC. Second opinion on biopsy slide reveals, moderate colitis with mixed infiltration, but not consistent with UC. As a next line treatment, I took metronidazole, ciprofloxacin, VSL3 and Albendazole + Ivermectin. All my symptoms got kicked off for nearly 1 month. Now I'm having constant bloating. Bowel movements after every meal. Excessive belching and flatulence. Cannot sleep because of bloating. Currently on ayurvedic medicine, but it doesn't work. I'm in a delima, that after consulting many GI, I couldn't get a proper diagnosis. Can anyone help. I will provide all my previous reports.
