I fell and hit the right side of my face on a piece of furniture this past Tuesday. I was knocked out and had to plug my nose with toilet papet to stop the bleeding etc..., untill yesterday everything seemed to be getting better (i.e. the swelling went down, less pain, my right eye opened and can see normally, etc...), then yesterday my right side of my nose\nostril and the nasal cavity place of my cheek are still swollen and have become kind of numb. There's also a small lump (like a bag, not bone) under the swollen part of my cheek. Should I go to the ER and get checked out, or is this all part of the normal healing process for this injury?
