Started suddenly on Wednesday afternoon, with waves of pain under my left ribs and then Wednesday night into Thursday morning with explosive diarrhoea every 20 minutes with little or no warning, abdo cramps and bloating . Went to bed in the early hours and slept through, but it started up again on Friday morning, albeit without the left sided pain and, after nothing since yesterday afternoon, it has just started up again.
I went to the toilet and had a normal BM and then five minutes later I had to run, only just made it, explosive diarrhoea, cramps and bloating again. I can't do my trousers up and there is a lot of gurgling going on. I'm supposed to be going out in 15 minutes, but I'm not sure I can.
The rest of the household is well and we have all eaten the same.
Any ideas what it might be?
