by all means, i am no doctor and it's hard to tell someone based on reading a few sentences, but from what you wrote, you are in some trouble here. when i read this about your nose clicking i gagged cause this happened to me at the end, i could literally feel my nose pop and although it did not really hurt it was a strange feeling. the feeling of your eye sinking in is because of that hole im guessing and it sounds like you have done a lot of damage like i did. surgery can help, but that just helps people use more blow. since you dont want anyone to preach to ya, i won't, but im guessing if your nose is that bad, your heart is double it's size also. trust me, this little nose problem is the LEAST of your worries.
Plastic surgery can repair the deviated septum in most cases...but as far as tissue loss....and other damage...sometimes those things are irreversible.
Certainly wouldn't hurt to have a consultation with a physician about it.
Best of luck!
Give gizzy32 a PM (private message) He has a lot of info on this. Glad that you quit, there is no repair healing of the septum that I am aware of. Send him a message.
