Sewing related injury

Somehow I managed to sprain or strain my left thumb using the lever for my presser foot on my sewing machine. It hurts. I'm icing it. That's pretty spectacularly pitiful, even for me. I was working on a hook case for my crochet hooks - I would up having to pick out a large portion of it anyway since at some point I let it drift off square. Sigh. Not my day for crafting. I did discover that having Oreo on my lap while I'm at the machine makes it easier for me to use the foot pedal. :P
