Hi. Since you are a known patient of IBS- irritable bowel syn Chat Doctor.  Well bacteria are not found on Endoscopy. The pain in lower abdomen / stomach can be due to colitis and that is why it is getting gassy weird pain going up on left side. This is to be worried as you need to be started on an appropriate antibiotic, metronidazole and anti-spasmodic with anxiolytic tablets. Relieve the stress and anxiety, one of the most important of IBS.
