Don't want surgery, can I fix my nose myself?

cartilage is flexible, but it has memory.  so while you can push it to one side, once the deforming force (your finger) is removed, the cartilage springs back to it original location.

As long as the septum has not completely blocked the right nostril at all times (you can still breathe with it sometimes), there are non-surgical ways to correct your breathing problems such as laser and/or radio frequency for tissue volume reduction of the turbinate instead of directly dealing with the septum.Manipulating your septum by yourself may cause more harm than good so it will be best to leave it to a specialist. Putting pressure on your nose, no matter how long you do it, will never change anything, it will never work.

You may be able to open up your nose by continuously pushing it over or dilating it but in most cases the improvement you will get for the effort is not worth it. Septoplasty can still be done under a modified local anesthetic with minimal downtime and expense!
