Throat hurts, can't even swallow my saliva?

Eating, drinking and even swallowing my saliva hurts my throat. I checked my tonsils and there's no white spots anywhere. I had a small fever last night, but it didn't last long because I took Tylenole. Right now I don't feel any other symptoms except for a sore throat. I drank orange juice the night before my throat started hurting and I remember a little bit of pain minutes after drinking it so that might had caused it. What do I do?
