I am currently being diagnosed with ulcerative colitis/Crohn's. Had colonoscopy on Monday and consultant reckons it looks like ulcerative colitis. Have to wait for biopsy results. In the meantime I am getting constant pressure on my stomach pushing up to my chest and it is extremely uncomfortable. I am also having muscle spasms on oesphagus. Are these symptoms of gastroduodenal Crohn's? Consultant says that if I am inflamed my stomach could be constantly producing excess acid. Does anyone have any experience of gastroduodenal Crohn's?
