Irritated throat

strawberry

For the last 3 days, my throat has been hurting, I couldn't really eat, it hurts so much to swallow. I ate 2 meals in the last 3 days, stayed hydrated though. I have no cough, fever, etc. I finally went to the doctor, she said it was really red, inflammed but not strep since there's no swelling or white spots. She said it could viral but she wasn't sure. Anybody had that before ?
