Broken Nose 7 Years Ago from a Golf Ball, Very Sore Pain in the Nose and Surrounding Bones Could It Be Related, And/or Serious?

A remote history of a broken nose (7 years) could be the source of recurrent pain. As the weather and humidity levels change, old healed fractures can swell and cause pain. 7 years is a very long time though. It's more likely due to seasonal allergies, recurrent trauma to the nose or underlying sinus issues. I would consult with a board certified plastic surgeon for advice and treatment if necessary. 

  A  broken nose can cause a deviated septum and bone spur formation the internal portion of the nose which can lead to headaches. Chronic sinusitis can also cause facial headaches as well.  Best to perform a CAT scan of your nose and sinuses  to delineate extent of the facial headaches  and any associated deviated septum.  A closed rhinoplasty approach is considered cosmetic and can straighten the crooked nose. Please see the link below for examples of how we have repaired a crooked/ broken nose

If you have developed sore in the nose or sinus recently, chances are you have a new problem not related to your nasal fracture of seven years ago. Best to see you primary doctor or ENT to sort things out.

 Might be related in that it may have caused a septal deviation that now contributes to sinusitis.  You may want to see an ENT Surgeon for evaluation.
