I went to lab school when I was in the military, and we had a section on parasitology. Since military schools tend towards practical application (versus bookwork), we were all (20+ students) required to bring in our own samples to examine . The day in which this part of the parasitology class was held is know as "Dooky Day" .
Hopefully they will figure which "bug" you have so they can give you something to kill it and you can get back to a normal diet.
Best wishes for a quick recovery,
