I also want to encourage you to look into EEN. It was my son's treatment to push him into clinical remission (no outward symptoms), however, remicade was eventually needed to completely eliminate all inflammation.
But, while EEN wasn't sufficient to maintain biochemical remission (no symptoms nor simmering inflammation), it did help him considerably and there are no side effects! He did six weeks of exclusive (no food) and then continued for an additional two years using it as a supplement (this was his maintenance treatment for this period). Approx. a year ago, he added remicade but continues to drink one to two Boost shakes now as a nutritional supplement. I very much believe the nutrition he gained throughout this time has helped keep him healthy and even controlled his crohns (to a point) without meds. Not suggesting you forego meds as simmering inflammation can eventually cause permanent damage but just saying it's a very worthwhile treatment to allow for bowel rest and, at the same time, offer nutrition.
Good luck with the new doc! :ghug:
And, by the way, I very much advocate for my son!!! I attend every appointment, receive copies of every test, etc. Not only does having you there help ensure that your son receives the best care, it also helps your child learn how to advocate for themselves when they eventually take responsibility for all their own care.
