traumatised (3285)
Firstly, with any symptoms like this you should go to a medical professional and get checked out, ASAP. However, these symptoms sound like they could be amoebic dysentery, a parasitic gut infection commonly passed through contaminated food/drink. It is accompanied by painful cramps and diarrhoea (which may be yellowish or contain blood), but easily treatable with Metronidazole.
