What are the changes like after breast fat grafting surgery?

I have a question for those considering breast fat grafting surgery. I am curious about the changes that occurred after the procedure. In particular, I would like to know the reactions to the size and shape of my breasts, as well as how those around me perceived them. I am also curious about how long the pain or swelling lasted and how long it took to return to daily life. I would be very grateful if those with experience could share useful advice, care methods, and precautions.
