Thank you for posting your query.
Dried nasal blood could be due to local injury
within the nose. And I hope that is the case.
However, please watch for any fresh bleeding from nose or any clear liquid-like discharge from the nostril
. If you notice any of these, we need to exclude any fracture
of the skull bone. You will then need to see the doctor.
However, if no new symptoms occur, no need to worry.
Wishing you good health,
Dr Sudhir Kumar MD DM (Neurology)
