Whats wrong with my throat?

Well, I had a sore throat for the past few days, And like I been having these for like 6 times each year. My last cold was in September 2010, and its June 2011 now. But I went to an Emergency today. And my doctor was a short Asian (No offense to some people.) and he ended up feeling my throat and everything, checking inside my mouth. I told him everything. Yesterday, I wasn't feeling to good, I felt like I was having a bad cold and a fever at the same time with a migraine. So I wrote down all the things that happened to me and I showed the doctor. I told him, the day before, I was dizzy, I had the signs of both a cold and fever, and I had aching legs, the migraine that made me cry badly, the sore throat / mouth. and Runny / Stuffy nose, Etc. It was just horrible yesterday. Now today when I went to the clinic place he told me to open my mouth and say "Ah" So I did as I was told and he shoved this weird looking two Cotton swab thing shoved together looking thing in my mouth. It hurt my mouth so much. I started gagging and I felt like spitting up flem. So I told me to wait there and I did for 2 hours. I see him going for lunch break and everything. So finally I was about to walk out, and he comes around the corner saying I have to wait again. I complained that I was thirsty and hungry. So he said he wasn't finished with me yet. So finally he comes and says it was negative? Is that a good thing or bad thing cause I'm worried. And he gave me pills that look like they'd last for 2 weeks, and he said he wants to see me again before school starts. So like, should I go back or what? Like whats wrong with my throat? Is it normal. A nurse said I had red spots on the roof of my mouth too, And I was told my throat was red in the back. So I wonder if I should consult this with my family doctor or just leave it be. But ever since that cotton swab thing was in my throat its killing my throat more. And I should add that when I was walking today I felt dizzy, and I felt like puking, I wonder if I should see the same Doctor and tell him what happened to me after I left the hospital, I also had head aches. Well Hopefully you can answer this, but is it Normal or am I just being over-worried?
