Hi Jaz
Sorry to hear you've been suffering. At least you are going to get properly checked out now.
I have GERD/acid reflux and have suffered on and off for some years - along with intermittent IBS. One can offset the other. I take ranitidine regularly - recently both conditions have been particularly bad but I'm not sure why. It's very scary having an acid reflux episode at night with the choking feeling, if I forget to take the antacids. I saw a gastroenterologist several years ago but at that point he said no need for any further investigations (just had bloods at the time which were fine and was screened for coeliac disease (negative) ). I'm thinking of going back to the GP though to ask for a referral again, as it does worry me when I have a bad patch, which can negatively affect things like holidays and eating out. I've never had endoscopy/colonoscopy and sometimes I think I should.
I think tiredness and stress can exacerbate the condition, and rich foods don't help either. But saying all that, I can have periods when I am fine for weeks on end. It's a strange condition.
Best of luck with your tests and hope you feel better soon
