get an xray. had the same thing happen and ended up shattering my knuckle when i put it back in place, even though it i thought it was just sore.
the doctor would just put it back in alignment the way you did. then they would put on of those finger brace things on to keep it stable for awhile. you can get the braces at local pharmacies. I think you will be ok.
It would be good to get an xray to make sure. Sounds like a dislocation but I would if I were you.
