Thanks for the replies on this all.
No I don't take any medication for reflux usually.
But I took yoru advice and gulped on Gaviscon for a few days, as well as eating pretty plain and bland food. Seems to have worked, although I did drink a hot tea yesterday which really hurt as it went down my gullet - could I have burnt my oesophagus? I have a habit of wolfing down food and drinks before they have cooled down, and I have burnt my throat before swallowing something far too hot.
However, now, my stomach has flared up. And I've been feeling really bloated, sore and uncomfortable below my rib cage. Nothing's shifting it, not passing wind or going to the toilet. Obviously this is quite rare to happen, but pains under the rib cage as well as bloating in that area could be pancreatic c, which my uncle died of recently. Obviously I'm really reaching here, but I don't know what also this pain could be. I've been eating plainly and sparingly........
Or is this once again some form of IBS?
