Baby is breech how to turn?

Had doc apt today and had an ultra sound done because during cervix check Doctor couldn't feel baby's head, like last week. So, ultra sound confirmed that he has turned and now is beech. Going in tomorrow to see if they can manually turn him, which I heard is the most painful. Anyone have any successful tips on how to get him to turn himself?  
Update ** so it didn't work, Doctor tried twice to get him to turn and no luck. Yes, it was very painful!! Hoping he will flip on his own in next week or have to have a c section😩
