White cell scan results can they be normal but feel so ill??

Hi,
I was just wondering if anybody knows anything about white cell scans?? My diagnosis is still a little up in the air-so for the time being Im labelled as severe ibs. My consultant does think it is crohns but needs histology to make a concrete diagnosis. In past ive had colonscopies which showed inflammation and faecal calprotectin raised significantly. I thought that the white cell scan that i had recently might give me answers but my results came back normal. This is reassuring yet I know from reading that peoples bloods have come back normal even though their crohns has been active. What is your opinion on this??. As at moment Im questioning my sanity. I have been poorly in bouts on & off for 8 years. For the last year I have been very poorly, severe weight loss rapidly ( 3 stone in 11 weeks, bm plus plus plus, , vomitting, mucus in stools, blood, rash, mouth ulcers, horrendus fatique- and at present too poorly to work. Im having a camera capsule in the next few weeks. Thanks for reading & hope you all are keeping ok...

IBS will not cause these symptoms. You don't have bleeding (except maybe hemmorrhoids,) inflammation, weight loss, fatigue, etc. with IBS. It's not your sanity that should be questioned, but whoever is diagnosing you. I'm sorry you're getting this type of treatment and it drives me crazy to see it still happening as that's exactly how I was treated many years ago. I even got sent to a psychologist at one point since it was "all in my head".

I hope you can see someone else soon.

Thankyou everyone for your answers. I dont believe its ibs either as have eliminated nearly every food going that maybe a trigger and even without eating which is often have these symptoms. I will request another opinion-I thankyou you all for your advice & support. Hope you are all doing well. x
