I Started Last Thursday With Chills And Flue Like Symptoms.

I started last Thursday with chills and flue like symptoms. No vomiting, but diarrhea started on Friday. I had diarrhea for 3 days. All of that has stopped, but I continue to feel very weak and generally sick. I'm drinking Gatorade and trying to eat small amounts but can't get over the general sick feeling. Could it be Salmonella?
