Two or three times over the past couple of years, I have woken in the night (usually after eating a curry) with bad pain under ribs on the right, also right shoulder area. It has been agonising but has passed over an hour or two and life has gone on. Last summer (July) what I initially thought was the same happened one night, pain in same sort of area but it lasted much longer and I was very, very sick. Eased up during the next morning and I was fine. I had had a fish and chip dinner on this occasion at an unknown restaurant and wasn't sure whether it was more likely to be food poisoning. Saturday night (after a curry), I woke up with pain under ribs on right again. This got worse and worse during the night and I was sick more times than I want to remember. This eased up during the morning but I have taken longer to get over it which makes me wonder whether it was a bug. The following morning I woke up with a stinking headache although this passed off after going back to bed with strong painkillers. Yesterday I was OKish but very tired and today I would say I am 95% back to normal. So my question is, do you think this changing pattern with "add ons" is likely to be gallstones or just coincidence and this time, anyway, a nasty bug. Having a friend who has just had winter vomiting disorder, our symptoms have been pretty similar!
