My Nose Has Been Bleeding For 3 Days Non Stop.

My nose has been bleeding for 3 days non stop. Also, it's starting to throb all over my nose and it hurts. The problem was at first was a nose bleed then couldn't breathe out of my left nostril, which is the problem. Now, I can't breathe out of either nostril, it's sensitive to the touch, and I'm having a lot of throbbing going on. My nose is all red. also, every time I blow my nose it feels like something else is in there as long as I feel like it's going to start bleeding again or have a runny nose.
