What do you need to know before a liposuction procedure?

I am considering liposuction and would like to know the essential things I need to know before the procedure. In particular, I would appreciate advice from those with experience regarding the post-operative recovery process and pain management. I would be grateful if you could let me know the expected swelling and the time required to return to daily life, as well as any care precautions I should take during recovery. I look forward to hearing your valuable opinions!
