"Only great pain, the long, slow pain that takes its time... compels us to descend to our ultimate depths... I doubt that such pain makes us "better"; but I know it makes us more profound... In the end, lest what is most important remain unsaid: from such abysses, from such severe sickness, one returns newborn, having shed one's skin... with merrier senses, with a second dangerous innocence in joy, more childlike and yet a hundred times subtler than one has ever been before."
-Friedrich Nietzsche, The Gay Science: with a Prelude in Rhymes and an Appendix of Songs
I can only hope he was correct. If you want to know what pain can really be just google CRPS.
