What procedure would I need for a deviated septum and overgrowth of cartilage?

3/12 years ago i was assaulted. i have overgrowth of two unknown pieces of cartilage(i was told) in my nose that has changed the shape throughout every month. Also i get alot of pressure around those certain parts of my nose where the injury is extending, It results to alot of migranes and facial and sinus pains. i consulted with an ENT specialist but he come out with no need of operation or medication. i was shocked after what ive been through and still going through. What do i do?
