I have always had this in left nostril only and if I put my finger in nose there is a small area at bottom inner that is tender to touch and bleeds if touched and always seems to have a bit of a bloody scab on it. As I have always had this and had my nose looked up many times and even had camera in sinuses I can only assume its due to weak blood vessels in an area of my nose.

My husband also goes thorugh phases of red hankes as well.
