Is Anyone feeling bad for a few hours than ok?

Today I woke up with a bad cough and a itchy throat. I didn't feel bad during the day but after I got some exersise and than I felt like I was going to puck and I kept coughing and my throat had got worse. I watched Harry Potter and than I pulled out one oh my baby teeth. I felt a little bit better after I got it out, but than the blood from my gum went itno my tonsils and made them hurt. I gargled some warm salt water and than it felt ok for a while, but now I'm starting to feel like crap agin. My throat hurts and I fell week and like I'm going to puck. Is anyone having this too and does anyone know what it is?
