dislocated or broken it...? I don't know what I did to mine. Middle finger, RH (picking hand). Was trying to pull the lawnmower out of the garage and yanked under the wheel wells and "pop" and "ahhhhhhhhh!" Knew I did something. Was able to move it - full range of motion. Iced it up. Hurt at first but calmed down. Next day, swelled (joint closest to my palm, like where you'd wear a ring). It's remained nominally swollen. It's sore and a bit stiff to make a fist - like if I make a fist I can feel a little presser where the swelling is and it makes it harder to fold it all the way down. It actually was doing OK - I could extend fingers, I could make a fist, with just a little "pressure" - like when I was a kid and used to "jam" my finger playing basketball (that's where the ball hits your finger dead on and jams it back into your knuckle/hand like driving in a post). At first, couldn't open a soda can (use my middle finger to pull up the tab) but could later. Got to the point where I could squeeze all around and feel no pain - so I just didn't think it was broken. More likely, feel like maybe it popped out of joint - dislocated and then popped back in maybe? Thought it was slowly on the mend but this morning was a bit more sore and stiffer. On touching it, most pain is on the palm side of the main knuckle, with fullness on the palm side of that first joint (where you wear a ring). Everything looks and feels symmetrical...except for the fullness of that first joint.... Can play Can even play classical (RH work no problem) and keys (and putting pressure on a piano key is no problem now, unlike initially).
