I am so worried and I feel this site is the only place to turn to for information and advice. I have been suffering with an extreme burning sensation in my stomach since August. I have been given Omeprazole by the doctor but it still persists. Today I underwent a Gastroscopy and was given the results. Apparently I have erosions and patchy erythema (red inflamed blotches I believe) throughout the stomach, Duodenitis and 4 ulcers. I was tested for H pylori which came back negative. I also had 7 biopsies. What is worrying me is my internet research. Every site I look at says that ulcers are caused by only two things - H pylori (for which I tested negative) or taking NSAIDs (which I have never taken since being diagnosed with PBC in December 2010). So this is leading me to worry what might be wrong with me. Does anybody know of any link that would connect stomach ulcers to PBC? I can find nothing on the internet to answer this question but then PBC is an uncommon condition and even most doctors know little about it. At the moment I am dreading the results of those biopsies. Thank you for reading this lengthy diatribe and I would be very grateful for any responses.
