Feeling of lump/pressure right underneath right ribs Options

[lucyinthesky7]

Hi, I have long been diagnosed with IBS. I also experience acid reflux and am due for a gastroscopy next friday (13th!!!). I wondered if anyone else has had this sensation of as if a lump or pressure under right ribs - some tenderness on ribs and - got worse after straining. Could it be hernia? Ulcer? GP couldn't feel my liver so not inflamed. It's been like it for 2 days and sort of itchy now. It's like a big stone has been jammed under there or something. Harder to eat than usual.
