Drains after BBL. How long are they in for? And is removal painful?

I am planning on getting a BBL very soon. However I have a couple of questions regarding the drains that are used after the BBL surgery. How long are these kept in for generally? I also wanted to ask if it is painful when removing them, and how is this done? I had drains in for a couple of hours after my breast enlargement surgery and remember them being removed being really rather painful. They almost felt like they were being ripped out of me from the inside out !! Please help. Thanks.
