I went through the history you have posted.
It seems from the history that you are having facial numbness
following facial injury and surgery for repair of nose.
Facial numbness is because of injury to the nerves supplying the face either by injury or during surgery.
Headache can be because of your deviated nasal septum
or recurrent sinusitis
Do consult your doctor for further evaluation and treatment.
Do write back to me for further questions.
Thank you for writing to health care magic.
