Every plastic surgeon provides post-op guidelines for BBL recovery. It's always best to ask the surgeon who performed your BBL for his/her advice as he/she knows what would be best for your recovery. This is a very common combination but recovery is uncomfortable. I allow patients to sleep on their sides. Lying on your stomach or on your back will create pressure on your butt or breast. Patients can also rest in other positions as long as the other areas do not receive pressure. There are creative ways to manage this. For example, my patient coordinator recommends a plastic inflatable with a hole in it (called a lilo), where instead of your tummy, you place your butt, so you can sleep on your back with pillows propping up your neck and head.Kenneth Hughes, MD, Board Certified Plastic SurgeonLos Angeles, CA
