#cannot english

I also need to rethink some of the physical demands of my week-to-week life because six hours at an upright easel a few times per week has sent me in search of a massage therapist. My dominant arm/shoulder is extremely unhappy and the muscles on the opposing side of my back are knotted. 

For my days spent at the art studio (atelier), I need to set up something equivalent to a standing desk like the one I have in my home studio, or I need to work on a smaller sized paper on a smaller sized drawing board that I prop like a lap desk while sitting. Otherwise, I'll end up with weekly visits to a physical/occupational therapist. Do not want. :/
