My greetings too! I don't know your age, but your doctor might not be giving you a formal Crohn's diagnosis to keep you from having trouble getting insurance. I know that once a diagnosis gets in your electronic records it follows you around forever. I had drug-induced lupus but since there was no code in the system, I got stuck with the lupus diagnosis even though it cleared up after a year.
The best way to learn about Crohn's is to read about the disease. This site has some great info and links on the Crohn's Resource page: https://www.healingwell.com/pages/Crohns_Disease/
Another great site is CCFA. CCFA has good info on living with Crohn's.
Also, please know that each of us is very different from the other. A med that works for me might make someone else sick as a dog. Something you can eat might make me pot-bound.
When I was first diagnosed, I started a food diary on the recommendation of another member. That way I learned what caused me grief and what were foods that never caused me problems.
Again, welcome to Healing Well!
