Hello Hayatbouya, I appreciate your questions! After VASER liposuction with fat transfer to the buttocks (Brazilian Butt Lift), pain and soreness may occur and should be relieved with analgesics. These pain medications are usually prescribed by plastic surgeons to help with general discomfort. Similarly, feelings of burning, and tightness are common occurrence during the healing process, but will decrease with each passing day. Your body may look swollen for months, but after 6 months you might appreciate your new and amazingly contoured figure. I would recommend you wearing specialized compression garments for 6 months and getting lymphatic drainage massages in order to completely alleviate the swelling and discomfort. Contact your surgeon promptly if you notice an increase in swelling, pain, redness, drainage, or bleeding in the surgical area, or if you develop fever (above 100.4 F), dizziness, nausea, or vomiting. Hope this is helpful! Dr. De La Cruz.
