Thanks for your question. In short, yes there are situations where the septum can re-warp to become closer to its original crooked position in the nose, however this certainly does not occur in every or even most septoplasties. The likely biggest contributor to the issue is how much septum is...
Thanks for posting your concerns. You must find an ENT provider that accepts your insurance. It should cover any functional airway surgery to improve your breathing. Without examining you, it is not possible to say exactly what needs to be done. Best of luck breathing better.
Not necessarily. If the headaches themselves are caused by the bone spur impacted into the side wall of the nose, removal of the bone spur will cure the sinus related headaches. These are not migraine type headaches.
