I have a pinkie that is either jammed or broken. It swelled and discolored a little at first, now it just remains a little swelled. I am 48. Tried to catch son’s football pass which bounced on pavement and caught my finger straight on.Going on 3 weeks now, still a tad swollen and can feel some minor pains when it is hit and a bit when bent. I can still use it. Doubt it would need surgery. Should I completely immobilize it (splint?) If so, how long?
