Should I go to the doctor?

Yesterday I woke up with a scratchy throat and a cough. I ended up taking a 3 hour nap in the middle of the day and woke up with a headache and I felt weak. I went to a friend’s house and it got much worse from there. I felt so tired and weak that the drive home took a lot out of me. When I got home, my temperature was 103 degrees and my chest and muscles hurt. I took some medicine and it was back to normal within 4 hours. I’ve been taking my meds every 4 hours and the fever hasn’t come back since. I still have chest congestion and a cough though.

I don’t know if I should go to the doctor. My fiance feels as if he has the same thing and three people in his family had the exact same symptoms and it went away on its own. This makes me think it’s not bronchitis, but I don’t want it to get to the point that I have to miss work. I can’t afford another medical bill, though, and I don’t want to waste the trip if it’s just a chest cold.

I know none of you are doctors, but what would you suggest I do?
