My grandson was diagnosed with Crohn's in his junior year of college. That was during covid so he spent his senior year doing home classes. His is extremely bad. Usually it effects one part of the intestine but his is throughout. He has had about 4 flairs since being diagnosed and has ended up in the hospital for at least a week at a time. My point though is he never had any symptoms before the first attack so it's really a good idea to have this researched further.
