That was just one example. If you want other examples of occasions in which it would be a good idea to "grin and bear it", here:
* A guy in a burning wooden house in danger of collapsing. The only possible exit given his current position in the house is the front door, except that the threshhold is on fire too. He knows that it will be painful to jump through the flames, but the alternative is worse. So he dashes through and rolls around on the grass to smother any flames.
* A guy is hiking on ground that slopes down toward a precipice on his left. He slips and starts sliding towards the cliff. For lack of anything better within reach, he grabs onto a thornbush oto stop himself. He would be wise to ignore the pain from the thorns and maintain his grip.
(This actually happenned to me, except fortunately it was a sapling, not a thornbush, that I grabbed onto.)
My point is that pain is indeed an excellent indicator of current harm or injury, but it doesn't balance that against future benefits. For that we need our brain. So one should heed it in most situations, but not all
