I've had a fever that comes and goes (I've had it for three days now). A bit of nausea, but, that's it. The flu?

Go to a doctor or clinic and spend the few bucks to get an accurate diagnosis please. It could be anything and only a qualified physician can make this assessment. Your health is too important to trust with strangers or laymen.

The last time I had the flu, and it was a strong flu, I was down for a few days and was all better after a week.
If it lasts much longer, get checked out.
The n1h1 is going around still.

Hmm, just fever and nausea? I think the flu is more upper respiratory issues…
Here’s the mayo clinic’s symptom list: http://www.mayoclinic.com/health/influenza/DS00081/DSECTION=symptoms

I was super sick when I got influenza, I could barely function. You could just have some virus. My son has been having a fever off and on, low grade (101) but still there…I think he’s fighting something as well, but I’m not sure what.

How high is your temperature getting? Does it come down with Tylenol?

With the flu it hits you all at once, and you feel terrible, trust me if you had the flu, you would probably know it. If you have a history of sinus issues, I would say to start there, because it is the time of year when everyone starts to feel the effects of sinus congestion and drainage. I have no idea if you are a guy or girl, but if you are a girl, it could have to do with your monthly cycle, if your a guy, obviously that’s not an issue for you ;-)
If you are really concerned though, go to your doctor, they will be able to tell you what’s going on for certain.
