I'm more of a hobby artist, so I am able take plenty of breaks and time off when I need to.

Holding the arms up/out for very long {easel} & the detail work does take a toll - Leaning over /forward when I work on a lower table top gets my neck /traps burning.

Has your PT worked on any posture imbalances & posture awareness with you?
What PT modalities have worked best for you so far?
