So I've had a pain in my right arm since Friday evening, which got worse on Sunday - to the point I can't lift my arm past my shoulder. I went to my doc's today, and the diagnosis is in : tendinitis.

It's probably caused by my stance when I draw, namely my fat arse pushing it up when I sit. Gotta work on that.

In the meantime, doc said I should move my arm as little as possible, so drawing is going to slow down. Hopefully I'll be back in working condition by the end of the week.
