I was at a festival so at first GP assumed food poisoning, my symptoms were
diarrhea (which became bloody after a week), vomiting, sweats, weakness
and fatigue. My GP did stool samples which showed nothing, but blood tests showed signs of infection so I was given Ciprofloxacin.
I couldn't eat at all for 10 days, and I lost 22lbs in just under 2 weeks. I was treated at a&e for dehydration, which did ease my nausea, but still couldn't eat.
