Just a follow up.
One thing I have learned from these forums is that most injuries heal better when you keep using the injured parts. (It worked for my golfer's elbow, even though it was excruciating for a while.)
The wrist still hurts a bit but it is improving. Don't know how I initially injured it but it may have been doing some reverse (pronated) barbell curls with my hands too close together. I have since moved my grip out a bit.
