I'm talented in so many ways. After my workout at the gym this evening, I was picking up my bag to go home and somehow, it slipped out of my hand, and my left thumb caught on the strap, bending my thumb backwards. Yes, you read that correctly, I made it all the way through my workout with no major issues, and then I hurt myself on my gym bag.
I've got it taped up now and am icing it. Depending on how it feels tomorrow, I may call a doctor. Normally, I wouldn't be terribly concerned about a sprain where I didn't feel or hear a pop, but due to some other potential mitigating circumstances (which I'll try to write about tomorrow), I'm starting to treat any potential soft-tissue injury with kid gloves.
