Am awaiting scan for gallstones having had horrendous chest pain incident and spent night in hospital with suspected possible heart attack 4 weeks ago (it wasn t heart attack, thankfully) I have been feeling nausea occasionally after food since then, but it is happening more frequently now, and a lot of burping. Is this indicative of gallstones, too? Two family members have had the problem, my sister 40 years ago and my brother s son last year, but my sister, understandably, has forgotten the details of everything except the pain involved.
