What is this skin rash?

[Kesley]

I have been having cold symptoms for about a week and a half (runny nose, nasal congestion, bad cough, fever) Yesterday I woke up and had a rash over my entire body. As the day went on my joints began to hurt very bad (mostly fingers, knees, and toes) Today when I woke up the rash has gone away a little but not completly, my fingers are swelled and hurt very bad, along with almost all my other joints in my body, my joints feel like they pop every time i move. Some of the other symptoms i have have are; red eyes, very tired, bad headache, and nauseated. Please help. I hope this is nothing at all.
