In Thailand we decided to go to a 5 star restaurant one night for dinner. I ordered two oysters as an entree, reasoning that it would be ok as the joint was 5 star (even though there were far less people there than the other, cheaper eateries). Not less than two hours later, I was more sick than I have ever been in my entire life. After 5 hours of non-stop vomiting and diarhorrea, I was lying on the shower floor puking into the plughole, when I decided to try another position. So I leaned over the bathroom sink. Exhausted, and trying to hold myself up, I glanced at my feet... and saw a worm crawl across the top of one of them... underneath the skin!!!!! I started shrieking and running around the room, slapping my foot to try and kill or get the thing out (as I had a cut from my flip flops that I figured it must have crawled in - ewww!). I didn't know what to do, so grabbed a block of cheese out of the fridge and rubbed it all over my foot, thinking maybe the worm would come out to eat it(???!!) but of course it didn't, so I spent the rest of the night crying and slapping my legs because I thought I had worms in me. The next morning I went straight to the pharmacy and explained what happened, begging for worming tablets (and rehydration sachets and other sickness tablets). She passed them to me, as she knowingly nodded her head, "Ahhhh, the worm!".
