Cold or More Serious

Patient: Do I have a cold or should I go seek medical attention? My throat started hurting, almost as if my tonsils were swollen. Then the next day, I woke up with my head filled with water feeling, and my ears were stuffed. I could barely move my head without it hurting.

Symptoms: Throat hurts (almost like tonsillitis), head full of water feeling (pressure?), ears stuffed
