Well, triple crap...
Yesterday, came home from the grocery store with some heavy items. Normally not a big deal, but after a while, I noticed my arm starting to hurt near my wrist. I could still use it in a limited sense, but certain movements like simply turning my hand over would result in sharp, intense pain. Skip ahead to this morning, and the pain has gotten worse. The last time I felt like this was when I got a micro-fracture in my hand back when I was a kid.
The good news at least, is that it's not my drawing arm, so I can still try to work on new projects (which I promise are coming, I know it's been a while).
The bad news is that I can't afford to see a doctor, so the best I can do is try to be as careful as possible until this heals.
