In so much pain

Jellybean

I don't know what is wrong with me. My head is hammering, I can't stop sneezing and I can feel shooting pains in my teeth like I do when I'm getting a migraine but other than that it doesn't feel like a migraine. My face is just full of it! Nose running like a tap. I was fine at lunchtime yesterday, it's come from no where! Anyone any ideas what this is and what will help?
