Ok so I have the usual, sniffing, coughing, all the usual cold/flu symptoms.... but then I also have blocked ears, if i blow my nose my ears pop, and for some reason I had hiccups tonight that were really painful >.>

Everyone says its no wonder I have a cold, cause I usually don't wear 'warm enough' clothes but I wondered what the point is, when I usually don't feel the cold... is this a circulation problem or something? Because isn't a circulation problem when you're always cold and can't control your temperature? =S

Please help me, thanks! xD
Oh and most of the time when I cough I feel like I'm going to throw up and sometimes, I end up spitting out phlegm after coughing so much...
