I developed a cold and sore and swollen knees at the same time, should I be worried?

Question

I may have had a fever with the cold. I did get a fever blister on my lip. I have trouble going up and down stairs. I've never had this problem before.

Answer 1

Go see a doctor. No one here will be able to tell you what it is, and if you are worried enough to ask here, you are really concerned. So go see your doctor.

Answer 2

probably just coincidence. would not worry unless the problem persists more than a few weeks.
