question: Hi, Last week I had some sort of virus it seemed (101 fever for 3-4 days on and off), and body aches during and a few days afterwards.  Now, 10 days after I initially got sick, I have a metallic taste in my mouth, and have boughts of light-headedness, and waves of naseaua (today is day 3 of this)...is this just an extension of the virus or something possibly more serious?
