What Causes Blurry Vision And Fluid Discharge From Nose?

i went to the dentist today and he hit a nerve while injecting the freezing. i immediately got an electric shock thru my face and up to my eye. my vision went blurry for a while. the freezing has now worn off my nose feels strange and when i bend over i have fluid coming out of my left side of my nose like a faucet and its like a yellowish color. is this normal from hitting the nerve in my sinus cavity?
