For the past 3 weeks I have had a recurring fever, which seems to cause headaches and makes me break out into a cold sweat. Lately, I've also started to feel an itch, mostly on my head and face. No rash, just itch. Also, my urine is darker than usual.

I went to the doctor yesterday and today to have some lab tests done. They had some blood work done and noticed something related to a viral infection, but aren't sure what is the cause. They are running some more tests to come up with an answer.

Needless to say, this is worrying me. Anyone have any idea what the above symptoms might be a sign of?

Thanks in advance.
