sprained two fingers fractured the bones used a splint for 4 weeks now both fingers are swollen and stiff. fell on my right hand and bent two fingers back waited two weeks and then went in for an x-ray that showed both fingers were fractured wore a buddy wrap splint for a month. now the splint has been off for a week and both fingers are still very swollen and stiff.
you will need to see your medical provider so you can have your hand/fingers properly examined. it would not be possible to determine the reason(s) for your swelling over the internet since the exact details of your fractures is not known.
