no although my GP has mentioned it.
I don't know what a ppi is although I do take a combination of omeprazole and ranitidine. I've had the problem for several months and the pain is increasing. I am providing my surgery with a sample of faeces within the next two weeks.
Thank you so much for your reply. I'm still worried about having cancer because I can't remember exactly how long I've had the problem for. How long would acid reflux need to be a problem before raising the risk that cancer may develop (I know that's a difficult question - I'm one of the greatest worriers of all time)!
Everyone says that using the internet in order to find out more about health problems isn't a good idea because it leads all of us to think we're about to die on the spot! I am reassured by your thorough explanations and reassurance. Thank you.
