Thank you for asking about your flank liposuction recovery.
Assuming this is an average liposuction of 2 L or less, you will hurt for about 3 days, be stiff and sore for about 2 weeks but be able to return to a sedentary job in a week.The final swelling result after all surgery takes 6 months.
If you have little children, it helps a lot to have help during the day for a week, and ideally 2 weeks as lifting babies will make you much more sore.
Always see a Board Certified Plastic Surgeon. Best wishes - Elizabeth Morgan MD PHD FACS
