Sick...please help!?

This isn't so much a women's health question but I'd rather have a female opinion as all of the guys I know run to the doc for every little ailment. I started getting a sore throat yesterday, went out with some friends, and by midnight I felt incredibly sick--my tonsils felt like they were on fire and I couldn't get warm, so I took painkillers and went to sleep. This morning I woke up with the same sore throat--it hurts to swallow, my tonsils are burning, sorry--gross--green phlegm (no cough though); I also feel achy and like I want to throw up (I have bad pms right now also--the nausea and achiness are part of my usual pms so I don't know if that is related to the throat stuff). Do you have any ideas on what this could be/what I can take to feel better? Please don't say "go to the doctor" unless you really think I should--I'm a college student and I don't want to spend $$ on an unnecessary trip to the doc. Thank you so much!!!
