I'm not sure if you are considering doing this or having it done by a professional, but here are my opinions:

If you are thinking about doing this yourself, pull *away* from the direction of the hairgrowth. That will help to minimize pain. Also another thing would be to take a nice hot bath beforehand then do your waxing.

I would have it done by a professional honestly. They will get it done and over with in a shorter period of time. After the first initial pull it won't be *as* bad. Two Advil before will help.
