NWR - i'm very sick - maybe someone can help figure out what i have

I have had a rash and muscle aches for 4 week and a high grade fever for over 2 weeks
i was in the hospital on friday
they have done many tests
and they don't know what is wrong
they think that it might be a virus that just has to get out of my system and it could take up to several weeks
they say the rash are hives it's just part of my body fitting

just wondering if anyone has gone threw this or might know anything
i'm just sick of being sick

thanks
