Rash, Rash, Rash…

I’ve had a rash since yesterday.  And I have no idea what it is.  It started on my neck.  And now it is on my chest, upper back, neck, shoulder, face, and my left ear.  I have no symptoms what so ever: no fever, no sores in my mouth, no cough, nothing.  It doesn’t really itch but I want to scratch so I think it is just mental.  I am going to get some Benedryl to apply and hope it goes away soon.  I hope it doesn’t lead up to anything.
