Many times people have nose bleeds and are very frightening. Sometimes it can occur through one nostril other times through both. Here are some tips on what to do
Lean forward and breathe in and out
Lay down
Pinch the nose
Blow your nose
Put an ice pack on the nose
Into the point, thanks for the info, but let me add something, the breathing should be by mouth so the blood will not go to your throat.
