I had this last year, and similar to other posters, although I kept going to the docs and saying "I think it's h.pylori" the GP kept saying it wasn't. I had scans for gallbladder trouble and all sorts.
The mad thing is, in most cases, it's something so easy to eradicate if it is h.pylori. I eventually paid for a private blood test, slapped the results down on the doc's table and had my week's course of antibiotics. The first course didn't work, and I was still +ive with the breath test last August so had another dose of antibs.
I think I'm clear now, I occasionally get a gastric gurgle or two, but nothing like before.
Go and insist on a blood test- some docs don't like to rely on the blood test because the antibodies will stay from a previous H.pylori infection, but at least it's a starting point for you.
Also, when I still had it after the first dose of antibiotics, my GP said, we'll try another round and if that doesn't work, we'll just manage it, apparently the feeling these days with it is not to keep bombarding it with antibiotics unless the symptoms are so uncomfortable that you can't live with it.
Alypaly suggested to me (and others) also to try Gastroctote tablets (or liquid) instead of omeprazole as they don't mess around with your natural stomach acids as much as the omeprazole type pills. I was still on omeprazole until December (doc said to take them for a further 3 mths to sort out the acid once and for all) but went cold turkey at Christmas (fnar) and just had the gastrocote every now and then, and now I just need one every couple of weeks. Peppermint oil capsules every so often are good too.
Hope you get some joy, it's a fecking pain to live with and yet something which can easily be sorted.
