Brazilian Butt Lift post op; my private is very swollen and my lips is longer than the other. Is this normal?

Swelling in your private area is very common after lower abdominal liposuction (which was likely part of your BBL). This should resolve, but if you have concerns, obviously seek advice from your surgeon. You should be examined to make sure that there is not a fluid collection that needs to be drained. 

Hello dear!!
Thanks for the question and provided information as well.
You are still early on the healing process, it can take up to six months to see your final results, so please be patient. At the stage you are in, inflammation is normal.
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)

Swelling in the vaginal region may be related to harvesting fat from the abdomen or from fat injection in the upper thigh region. This is not uncommon. If you have concerns see your doctor.
