In early 2020, after 5 years and 3 separate doctors I figured out why my belly hurt all the time. It was crohn's disease. But hey, good news, I could start treatment!
The first treatment we attempted, because we had to, was Azathioprine. It is provided freely by our government's free healthcare service, and it works for a lot of people.
Well it did put the crohn's into remission. After a month I took my first normal shit in eeeeh nine years?
Small problem, it was too toxic for my body and my pancreas rioted.
Anyway we started with Entyvio after I got over the pancreatitis, it is not provided by the government but my parents' health insurance covers it and we found a way.
