Hello Suz, sounds like you've been through a lot. I ask many quEstions on here, and it helps so much when people share their advice and experiences, so dont apologize for asking.
I agree, that in a flare, more D, more urgency, more irregular bouts of pain, and deff more fatigue. Usually inflimation markers are high, then you may be put on prednisone if other medication isn't controlling the crohns. The prednisone may bring inflammation under control (temporarily in most but Iv read here it actually puts some people in remmission), but it has many side effects, and can make other 'flare' symptoms worse. Fatigue being most common on here, but for me its like i can't cope with it physically after many years of Pred, and it puts other things out of balance.
Inflamation under control, many might not feel their then 'flating' but when my crohns symptoms are more full on, even on Pred, I still say 'my crohns is flaring today'. Just because it feels worse in some way. But then Iv never been in full remmission, except a very short period, and some say on here, while crohnsxis active, your in a flare. Well in that case, we're all in one big constant flare, so instead, for me it's the 'worst' of times with crohns that I consider flaring.
Best wishes, and ask as many questions as you like. I wish I found this forum earlier when I could of trialed diff meds and diets, but better late then never. So I plan to ask, even if little symptoms, because the people on this forum all live with ibd, and have similar experiences, and any advice I can gain for future reference, and well being, wether supplements or medications, could potentially be really beneficial for my crohns. So ask away.
Beat of luck with everything xoxo
