i tell ya this do whatever it is the doc tells you to do to keep that finger straight to make sure it heals as straight as possible
i donno how old you are but here i broke my finger i chipped the tip of it when i was 18 and here being 23 now it didnt heal properly and it hurts still and i can feel when its getting cold out and so on
do what it takes or your hand could be mangled for a while sorta deal
