Tired w/ Headaches 5 Weeks Post-op - Normal?

In most people discomfort and pain after
rhinoplasty settles 24-48 hours after the surgery. In patients where the nasal
bones have been narrowed, termed osteotomies, a minority of patients may find
some sensitivity and discomfort over the bridge of the nose intermittently for
several weeks.

In addition there is some swelling on
the inside lining of the nose that can result in symptoms of congestion, this
can result in headaches particularly in sensitive individuals if coupled with
other conditions such as hay fever. These patients may benefit from additional
medications during the recovery period. Very rarely there can be other causes of headache and tiredness and it would be worth returning to your surgeon for further evaluation and treatment.

It is not normal to have fatigue and headaches 5 weeks after rhinoplasty. You should be evaluated by your surgeon -  these symptoms are probably related and can be relieved with proper treatment.
