That looks painful, best of luck with your recovery. Not sure if this can be of any help to you but I really like this wrist brace, it helped with my lingering pain and fatigue caused by an injury many months ago. I wear it over a regular glove and it gives me some much needed comfort.That little chunk is attached to my ulnar collateral ligament. Don't think ice and rest is going to fix that.
Interesting to see that little floater by my index finger. That was probably a little bone chip from a crash a decade ago.
