    Doctor recommended I get tested for my Entyvio levels two weeks after my last infusion. I later learned this is the wrong schedule - you are supposed to get tested right before your infusion. I felt that she didn't listen/pay attention to my messages when I told her my infusion schedule. Unfortunately this type of problem occurs frequently with this office.

    We had a surprising discussion about the possible termination of my current medication which I am still confused about. Also the prep used this time was ineffective. I have done maybe about 10 preps so have experience but this prep was ineffective for me and now I have to repeat the colonoscopy. The biopsy results are still confusing to me in terms of their severity. Possible bowel resection or removal was discussed which was surprising as I didn't believe I was anywhere near that level of issue. Their is no sign of inflamation but there was serrated tissue so I am confused what is causing that.
