Rash spreading on face

Hi I’ve had a rash from when I woke up on the left side of my face. Throughout the day it has progressed up and all over my face and behind my ears/neck. I had a blood test about a week ago and it showed I was brewing an infection and my throat is swollen from examination. The rash hasn’t gone anywhere else as of yet. I am feeling quite nauseous with it and sensitive to light. Any ideas what if is? Here’s an image of it:

It may be Rubella, ...have you been vaccinated?   With nausea and sensitivity to light you should see a doctor immediately.   Dont know which part of the world you are in but if you havent seen a doctor yet,then go to A/E or ER.

Hi. Yes I've been fully vaccinated. I am in England. I saw a nurse who just literally discarded it. It's still here but hasnt seem to have spread. Thanks for reply. 

Did you have a temperature about 4 days before the rash?  Have you had a vaccination for measles? If so you need to see a Doctor as it is a notifiable illness

Good Luck
