Thanks for asking Minnie.
I'm on the mend.  I took my brace off to eat dinner (so I won't get food on it, I put it flat on the table next to me, sometimes ice it during dinner) and noticed there was less swelling that the bump had gotten a bit smaller, so it's healing, but it's going to take a while.  I'm going to be in the splint for the Hawaii trip the entire time except while swimming (but if I come out of the water for any extended period of time, the splint goes on.
I can type for short periods on my tablet, then I have to take a break.  It hurts after a while.  Not sure why since it's my thumb that's injured, but that's the way the cookie crumbles.
FYI, this is the state of my arm for the next 3-4 weeks (at least).
