Wasn’t all that bad, but an ER doctor was setting my “mallet finger” and used the wrong splint. When I got home, I googled it, and saw it did not appear to be the correct splint, so I went to my own doc and she said yeah, if I kept that splint on for the six weeks, I would lose some function in that finger permanently. She gave me the correct splint, and later, called it the best outcome she’d ever seen. Often there is a residual lump in the finger, although functionality is restored. I got full functionality and no lump.
