Not physical pain but emotional pain. He's struggling emotionally with his craft.

Answer 2

All things considered, angst is a perplexing and confounded feeling. One may even say this feeling could result in disdain which frequently drives an artist into setting very elevated standards of progress. This dislike of one's own work or self could originate from the profound sentiment of angst for the idea that they should, or even must, do much better than what they're presenting to self as a piece of art. Then again, one may state angst could keep a craftsman down in their work, stuck in a mindset of no progress. It is important to notice, thought, that some artists accomplish extraordinary works because of their angst.
