Does strenuous activities, like jumping, affect the nose structure/manipulate it, or does it just cause more swelling?

Increased activity shortly after rhinoplasty caused temporary swelling so I advise patients to just take it easy for about three weeks after rhinoplasty

There’s no yes, or no answer to your question. A lot depends on exactly what was done during the procedure, and the timeframe and what you referred to as a strenuous activity. Any activity that directly puts pressure on your nose should be avoided. If you have specific questions regarding specific activities, then I suggest you ask your provider.
