Disclaimer: I know you are not my doctor and I will contact him if necessary.
Yesterday I ate my regular meals including a prawn cocktail (prawns in marie-rose sauce.)
The prawn cocktail tasted a little funny, but I went ahead anyway.
Today I felt fine and ate my lunch.
Soon after, I had to rush to the bathroom, where I had a swift bout of diarrhoea.
Since then I have felt fine (and my appetite is normal.)
Of course I will get medical advice if I get any further symptoms.
My question is - assuming the prawn cocktail was ‘off’, would it explain what happened?
