If you have a deviated septum or something that is causing your nose to be crooked then you have probably had about enough. Maybe this is causing you to be very self conscious about your appearance but this is a problem that can be corrected.
Visit an Otolaryngologist. These are the doctors that will perform rhinoplasty on your nose. They actually change the shape of your nose.
Breathing with difficulty might constitute your health insurance provider actually covering the procedure because it goes from cosmetic surgery to a medical procedure.
Fixing a crooked nose requires the surgeon to have to target the nasal bones as well as the septum. To fix a deviated septum, your cosmetic surgeon may remove a portion of the septum or place tiny incisions in it to realign it.
This is a relatively unpleasant surgery so make sure that it is high on your priority list before really considering it. If you are having difficulty breathing it may be covered under your health insurance. The cost without insurance is around $5,000
Make sure that you see a qualified and certified physician for this procedure. This is not the time to try and save a few hundred dollars.
