Are you on any special diet?
Only during a bad flare up, If i'm admitted to hospital they will put me on a fluid diet for a day or 2 to give my gut time to rest & then it's just bland foods & things that are easy to digest till i feel comfortable eating different thing.

During a severe flare up it's hard, i can be bed ridden because of the pain & i usually flat out refuse to leave the house. It's also when i'm admitted to hospital for 5-10 days to get it under control.
During mild-moderate flares it's not too bad, you will feel more tired & weak at times but you also learn to cope.

Lots of hugs & i hope it's not Crohns.
If you don't mind me asking, why does your gp think its crohns?
Feel free to PM me, i'm happy to answer anything i can
