Taking a pain killer so you can do something your body is telling you not to do is not wise. Pain is a warning. Listen to it.

If you back off on the quantity for a while, she might regain some tolerance. She has become over-sensitised to your ejaculate. It would not be good to press on regardless, as the next stage could be more violent. I'm amazed the doctor gave such advice.
