Ok..... I'm a little confused. You just said you couldn't bend your injured finger....but immediately after you say you can bend your injured finger backwards? Ummm. Your finger isn't broken, and even it was all they would do is tape it to a Popsicle stick, there isn't really much you can do for a broken finger. Unless it was mangled or something. So sounds like you'll be back playing basketball soon.
as an xray tech, the only way you will know is to get an xray taken. they may just splint it or it could need to be pinned by a surgeon depending on how it is.
I am not sure but try to apply some oilor ountment and massage your finger thoroughly. After a few days try to bend your finger
i have three grown boys...a marine, a chef, and a model....all played many sports im no dr. but they always jammed there finger...like a dislocated shoulder..i would pull it out for them...hurts but they said it felt a lot better...and able to use it again...good luck...
