Is the bbl and lipo 360 procedure very painful or just irritating???

Hello and Great Question.  I appreciate the time you are spending researching this procedure.  My name is Dr. Matthew J. Nykiel.  I am a Board Certified Plastic Surgeon, a Fellowship Trained Cosmetic Surgeon, and a Butt Augmentation Specialist.
I perform a number of Fat Transfers (BBL) on College Students and Professionals.  These are individuals that also are required to sit for the majority of their day.  For the 1st week, I only want you to sit when going to the bathroom.  After the 1st week, you may sit on a pressure off loading pillow.  The college students and professionals do it all the time and they are very satisfied with their results. 
I utilize a 4 week sitting protocol.  Again, the 1st week I like you to be off your butt as much as possible in the early stages of healing.  The protocol is: ◦ Week 1: Sitting for the bathroom ◦ Week 2: Sit as usual with the assistance of a pressure off-loading pillow. If you do not have a pillow then: 15-30 minutes at a time, then standing up to shift your weight. ◦ Week 3: Sit as usual with the assistance of a pressure off-loading pillow.  If you do not have a pillow then:  30-60 minutes at a time, then standing up to shift your weight. ◦ Week 4: Sit as usual with the assistance of a pressure off-loading pillow.   If you do not have a pillow then:  1-2 hours at a time, then standing up to shift your weight. ◦ Week 5:  No Sitting Restrictions.  Sit as usual.  Unless otherwise directed.
WORK:  Most of my patients are back to work in 1 week or less.
ACTIVITY:  After 1 week you can Run/Jog or go to the gym.  Prior to 1 week, I want you walking around as much as possible.
GYM:  After 1 week you can go to the gym.  You can do any upper body work out and/or Run/Jog.  No lower body squats or any activity that requires you to place pressure on your Butt/Gluts (i.e. Leg Press, Back Row etc) until after 4 weeks from surgery.  
Overall, most patients are back to work in 3-5 days.  A portion of my patients are even out to lunch/dinner directly after the procedure.  
Best of Luck!

Post operative pain will vary from procedure to procedure and patient to patient. Liposuction is generally well tolerated with most patients comparing the discomfort to post work out soreness. The fat transfer component does not add a great deal of pain to the procedure.Most patients will return to most activities of daily life inside of a week (save for those restrictions associated with off loading and pressure recommendations).As always, discuss your concerns with a board certified plastic surgeon (ABPS).

There is certainly some degree of pain that is associate with liposuction and BBL.   Most patients feel much better after the first 3 to 4 days.
