How do you know if you've dislocated a knuckle?

It's possible that you just bashed it in your sleep. Your nightstand can be deadly if ya let it..lol . Seriously, more than likely you strained that finger and it's letting you know. If you have any swelling, discoloration, rash or even a bite you dint notice before, you may want to have a doc check it out. Mosy likely, he'll put a splint on it to keep it from moving to much so it can recover. Hope it feels better soon.

if its truly dislocated you won't be able to bend it. You may have just 'stoved' it, which is when u ram a finger down into your own hand. try GENTLY pulling on the finger, take rings off first. Also put ice on it if it its better soon, go to the ER.

ur finger wouldn't be straight and u couldn't move it at all. it's horrible pain to dislocate a joint, so if ur sitting there typing...it's not dislocated. u should still see a dr. if the pain continues.

if you were to dislocate any part of your body you'd know, and be in horrible pain...

If it is not at an angle and you are not screaming, it is a sore cartlidge.

lol well ask the knuckle..haha jk

well if it hurts..

ask a doc.
