i think many of the artists and actually everyone who uses fine motor skills deal with it.
it's actually annoying condition because you not just can't draw but you can't use your dominant hand in way you used to it - grabbing, eating and etc.
And that's why i don't post often right now - i am still recovering and searching for more healthy way to organize my drawing process
I feel better than it was weeks ago - taking pills and making physical therapy are helping me to go through pain and numbness
So, take care of yourself - don't push yourself to draw through the pain and give yourself some rest because it's really important in long run
