Week 4 of horrible stomach bug that keeps coming and going. Intermittent diaorreah, nausea, headaches, tiredness, weakness, and terrible smelling shit and farts. They make the nausea worse. Also crippling stomach cramps all the time.
Finally went to docs today, and she suggested it was this. However I haven't got diaorreah all the time, but there is always a sense of urgency iykwim.
Is this how it presents? Am fanatical about hand washing, not travelled anywhere, drunk from a pond or licked anyone's bum. So where have I got it from. 
She took a sample and gave me metrinozadole. Have taken one so far, but feel so so shite....
