Thank you so much for your response. What you've written has been very helpful. I hadn't even thought of drawing with my elbow instead before. While I've recently planned to see a physician for this, I have also tried drawing with my elbow now and did 13 more boxes over the course of 6 days with no pain. The cracking went away when I draw, too. That's been really great and I'm so much happier. I am at box 202 and will continue drawing.

And everything you said is completely understandable. I realize this isn't a great place for this, but its just hard for me imagine a physician knowing enough about drawing to suggest I use my elbow instead, like you did. Almost everyone thinks its done with your hand/wrist (people who do not draw, I mean). What you said has worked. I appreciate it.

Thank you again.

Note: You were right about smaller strokes. I've noticed I can't help but draw my boxes a fair bit smaller than before.
