Me (24)and my gf(23) both have similar things going on. me- slight pain/pinch in lower left abdomen, nausea, smelly farts, burning stool. gf - same symptoms except she was puking around 3-4 in the morning and i havent puked yet. Im trying to figure out if what we have was something contagious, what we ate, or the weather. -she works with babies, and in the past 24 hours ive been around my gf and 2 others who arent experiencing this illness. -only things we both ate were brownies from cicis, and store purchased hummus. i had hummus 2 days ago and havent felt anything until the brownies which makes me think it was possibly them. - and we live in NC, so lots of bipolar weather and rain with 40-50 degree weather. i know its a lot but any inaight would be greatly appreciated!
*Insight
It sounds very much like a bug since both of you have it. If the brownies were fresh, I can’t see them being the cause of your sickness unless both of you are intolerant to an ingredient in the cake at the same time which would be a very big coincidence. If you have had brownies in the past and not experienced any problems, it doesn’t seem likely that you have had a reaction. On the other hand you can suddenly get an intolerance out of nowhere when you previously had none. These are quite remote possibilities since both your symptoms came on so quickly.
During the winter months, many bugs circulate and since you have been around your girlfriend for twenty four hours, it is highly likely one of you has passed the bug on. These bugs are highly contagious and some of them last 24 hours. Concentrate on getting better and don’t focus too much on the cause; it will only stress you out. Your girl friend should stick to bland foods or avoid food for a short period until her stomach settles down. and take plenty of fluids. Since you have not vomited, stick to bland foods and do not worry!
