I just flew back from the Ft Myers/Sanibel/Captiva FL area last night. Started to feel bad in the ATL airport. By the time I got to Memphis, I was in pain all over and could barely walk. Both feet & ankles were so swollen they were much bigger than my calf. All night, up with very watery diarrhea, very nauseous, a bit dizzy & lightheaded. All day today, Diarrhea has continued with nausea, fever, chills, headache & body aches (like flu). I have a very mild sore throat. Between trips to the bathroom, I have slept all day. Any thoughts?
