If it was terrible, terrible pain then he may have enlarged prostate. He should ask his urologist about that. There are meds to reduce the prostate size and symptoms if needed.
That being said, and again depending on just how much pain he had, he can ask for Valium and a few pain pills. He should only take the pain pills if needed. Could be that Aleve or Tylenol will do the trick but it should be discussed with the doc. Never take meds (especially something that thins the blood) without the doc knowing.
I'm assuming that you are driving him. Driving on Valium or pain pills is not advisable. It counts the same as drunk driving....
Congrats on the all clear!
