Broken Finger?

I believe I broke my index finger a couple months ago while helping move a refrigerator (got smashed) I am unemployed and have always seen people with a broken finger just get it immobilized with a splint by a Doctor.
So I figured rather than spend the money going to a doctor I would let it go and hopefully it would heal.
The swelling which was quite bad has all but disapeared and I can use it for the most part. Although it still will not bed all the way. feels tight and hurts if I try.
Will the eventually get better? Or am I gonna need to get a doctor to do something horrible like rebreak it and set it or something.
