Im Worried

three days ago i came down with some sort of sickness...
whats bothering me is that i dont know what it is. During the day, i still feel pretty sick, but it always gets worse during the evening, and my throat will start hurting really bad at night, in the morning, but as the day wears on, it will subdue to where my throat dosent bother me as much. im also getting fevers off and on, and i seem to feel nausea all the time. But most of the time i still have a appetite, just not as much as i usually do. im only 15, and am really worried. So please, any advice will be greatly apprecieated.

sounds like you may have postnasal drip since it's worse in the evening.

try some nasal saline rinse and see if that helps.  it's over the counter.
