Ellen83,
Tough place to be, and the doctor isn't making it any easier for you.
In my experience doctors are very quick at putting you on all kinds of heavy duty meds, telling you diet has no effect, and supplements don't work.
Not True!! Many meds give you side effects than worth while, including if you are intolerant of mesalamine meds - more stomach pains and diarrhea. Has your doc told you about the possible side effect of blood cancer as a result of Remicade? .
I balked at Remicade - too many side efffects.
Have you considered:
SCD diet, but also: add L-Glutamine powder (15 grams) - I take mine with my protein shakes - L Glutamine is known for colonic repair. Also you could take 3 x per day: Slippery Elm Bark Powder - it is nature's mesalamine equivalent - it will coat your whole digestive tract.
And lastly, you could give some thought to trying Transdermal LDN, safe, cheap, no side effects - you can google Dr. Jill Smith studies on Crohns Patients going into Remission with LDN. You have everything to gain and nothing to lose. But don't expect your doctor to be on board, because he won't be. I've posted a link here to an earlier post on it, if you want more info: https://www.healingwell.com/community/default.aspx?f=38&m=2079694
Good luck to you, and keep us posted :)
