Sorry to hear about your discomfort. The best thing to do is go to a doctor and request a stool sample be taken. Have it analized and wait for the results. If in fact there is a bacteria discovered please call your local Health Department with the results. At that time the Health Department will probably ask you for a 72 hour history of where and what you have eaten. Accuracy in this information is of great importance. Your local health department will then most likly investigate the possibility of a foodborne illness.
