Pain is really important. You can't properly heal from an injury without pain, because you won't know when you're worsening the injury. In the worst case you'll get into a descending spiral where you need to take more and more painkillers as you attempt to go about your day normally until you've injured yourself to the point where painkillers are no longer able to let you ignore the injury.
And in the best case (and almost 100% of the time) you'll just heal anyways, but won't give a shit about the pain and will actually be able to do stuff.
I think I'll roll that dice, thanks anyways. I'm generally able to restrict myself without the need for pain.
