Hi, I’ve been I’ll for about a week. Started with fatigue, lethargy, headache and sinus pain which I put down to a cold or the flu, but since Monday I’ve started with yellow mucous diarrhoea, bloating and gas which is leading to come nausea. I feel fine in myself now but still have diarrhoea, I do work with animals so I am aware giardia is a possibility. Any advice?
