I had a appointment at the hospital today and i asked, I was told it couldn't cause jaw pain. I don't think he knows for sure though, I bet if i asked someone else they would say something different.
I was told also that my septum wasn't straight(which I knew)and he asked me how that happened because my septum was only corrected about 6 years ago. I said I didn't know because it's not like I've had an accident in that time or been punched etc.
So maybe I'm right about rubbing your nose hard when it's really itchy because of an allergy? Maybe that can damage your septum? Because I can't think how else I could have done it.
