Possible to Fix Stretched Septum?

It sounds like you have a deviated septum. This particular problem can be addressed by a surgeon who is familiar with septoplasty.
The portion of the septum that you are referring to sounds like the "caudal" portion of the septum, and significant deviations of this portion of the septum can be a little tricky to repair. My bigger concern is whether or not a surgical procedure is going to restart your urge to manipulate your nose.
I would be certain that you are not going to have the urge to manipulate your nose prior to undertaking any surgical procedure on your septum or the surgical procedure will ultimately fail.

It is very likely you the surgery required is a septoplasty. You would need to be examined of course to confirm. However not everyone with a crooked or deviated septum needs surgery. There are lots of people walking around blissfully unaware they too have a deviated septum! Septoplasty is only indicated if there are symptoms. So if you don't have difficulty breathing, your nose doesn't appear crooked or you don't suffer from nasal crusting or bleeding, the best course of action is in fact to do nothing.

It sounds like you have a deviated septum, and this should be able to be corrected in experienced hands. If you have been able to completely stop the tic that you feel created the problemto your septum to begin with, then you would be a candidate to have the septum repaired. If you still find yourself doing the tic from time to time, you may need to have this controlled first to minimize recurrance of the deviated septum.

Hello,
You would really need to be examined in person in order to determine what the best option would be for you. Fixing a crooked septum is possible by performing a septoplasty.
Thank you and best of luck.

You really need to be examined and evaluated.  If your septum is deviated it can be addressed by a septoplasty.  It is difficult to say what needs to be done with a proper intranasal exam.
Good luck.
