Sounds like you passed it to him or he passed it to you its easily spread via bodily fluids. I was a great clinical preceptor that's how I picked up on all of this and was able to figure it all out I got an award for it when I was in school. I had the same issues starting about 2 yrs ago and it all just got progressively worse. They will try to tell you it's just celiac or ibs or crohns disease don't believe any of that bullshit they did the same with me I knew better. Like I said I believe this is becoming epidemic if not pandemic in nature at this point and I whole heartedly believe it's being caused by actinobacteria or t. whipplei.
