I recenty suffered a bout of disrrhoea, I didn't eat for 24 hours and thought it had cleared up, the follwing day the diarrhoea returned along with numerous stomach cramps. Again I stopped eating for approx 36 hours. When I did start eating I found I had little appetite and my stomach was still cramping and I felt slightly nasueous. Stomach pains continued for another couple of days and although bowel movements were returning to more normal types they were yellowish in colour.

A week later and I am only really feeling normal now, is it likely that this was just a bad tummy bug or should I be concerned that it might be something more serious?
