Nose bleed after waking up

Patient: Hello,Is it normal if i blow my nose after waking up, its bleeding? My left nostril have been bleeding in my whole life (so its nothing new) if i had a cold or anything, because of blowing. Now if i wake up, i feel my nostrils are blocked, so i blow it, but it starts to bleed. I guess it might can be an allergy, that makes my nostrils blocked and dry at night. Thanks for help in advanced.

Symptoms: Bleeding, blocked nostril
