Roseola.net

I’m 14 and I’ve had some virus for about 3 days, I’ve had a fever for all 3 days, I’ve been coughing, my eyes have hurt , I have had headaches, my throat is sore and I’ve been naceous. The fever goes away for awhile then comes back and it’s been around 101.1°F to 102.0°F, today I noticed a rash on my back, stomach and my chest, the rash looks like red flat sploshes, they don’t itch or anything. It looks like roseola to me but aren’t I too old to get roseola? I thought it might have been the flu until I got the rash.
Please help.
