8 Days Post Septorhinoplasty, Feel Movement and Clicking?

It's hard to know what that means at this time. It is not unusual to get some clicking sounds due to scar tissue after a rhinoplasty. It is unlikley that it is the bones still moving unless you are pulling on the cast with quite a bit of force. It is more likely that the clicking is not anything to be concerned about at this time. I would certainly mention it to your surgeon at your next follow up visit. In the meantime, I would leave your cast alone.

Clicking one week after rhinoplasty surgery is difficult to place exactly without knowing what was done in surgery, and without an exam. Best to ask or see your surgeon.

I think its very wrong in the first place for you to try to displace and thereby distort your nose at this time when tissue are still healing in the depth.For such patients I normally reapply the nasal splint after 7 days for additional 7 days and If I fear return of swelling I advise use of nasal splint at night for next 2 weeks.
