What concerns do you have regarding side effects after eye and nose surgery?

I would like to ask those planning to undergo eye or nose surgery: What concerns do you have regarding post-operative side effects? In particular, there are various possibilities such as pain, swelling, and changes in sensation. Does anyone know of methods to minimize these issues or management programs provided by hospitals? I would like to hear from those who have experienced this firsthand. Knowing what measures you took to recover would definitely be helpful.
