TOXIC SHOCK SYNDROME?!?!

HELP OKAY IM FREAKING OUT! I HAD MY TAMPON IN FROM 11 till 10 am and I just suddenly experienced nausea,intense cramping, and now diarrhea! It was up until 30 minutes ago on my drive home from subway and sonic and it was just intense nausea. I don't think it was the tampon. I did have 3 day old beef and chicken fajitas... could it be food poisoning?
