I have a large septal perforation. Any suggestions?

I have a large septal perforation that is causing me severe migraines, sinus inflammation and pressure, difficult breathing , vision is blurry and am all messed up from my equilibrium being off. i have a constant nasal drip yet I can't find one doctor who will help me or knows how to repair this. I have been to several doctors, surgeons who say that it cannot be fixed... so what can i do about this ..i just can't live this way.there has to be something that can be done , someone who can help me .
