It's been a week since my BBL, can I go back to work?

You should consult with your plastic surgeon and get his or her recommendations. I typically recommend that my patients take at least 1 week off from work. 

You can go back to work after on post operative day 8 ,if you feel well enough to work. Remember, you must have your doctor's approval. Jaime Perez MDPlastic Surgery Center of Tampa

Hello dear!!
Thanks for the question and provided information as well.
I recommend my patients to allow 2-4 weeks for recovery, and to wait at least 7-10 days before going back to work, but each doctor has their own protocol.
I also recommend not to sit for more than 30 mins. every two hours, for the first 2 weeks, and always with the help of a boppy pillow. It is very important that you talk to him and follow his instructions.
Hope this is helpful. Good luck :)
