Sore throat for 3 days.....?

On Saturday in the afternoon i was trying on some moldy clothes (don't ask :( ) and later that night i was drinking with my husband when i started getting a sore throat. The next morning i felt horrible. Nausea, headache, feeling faint, sore throat, chills and i felt a little hot. Later that evening i had a fever of 100. It has been down but now i have a stuffy nose, cough and a sore throat. Today is its third day and i am a little concerned. What could it be?
