In reply to AymanC:
I did the same to my ring finger mountain biking - fell on some wet boardwalk, kept sliding along, ring finger went down gap between the boards and I carried on. Very similar first few weeks to yours by the sounds of it, although if was trying to ride with it rather than climb.
I did g it x-rayed in the end, just to be sure, and I did strap it for riding a bit (just simple support above and below the joint), but essentially it's a long slow recovery. I found it got very sore if it got cold and stiffened up easily - very annoying for riding and skiing. Had to change to 1-finger braking on that hand as ring and pinky were secure enough. Usually it was just a case of keeping it warm and mobile as much as possible - wore glove and mitt on that hand skiing that year. I can imagine bouldering making it very sore.
Full range of movement in a year, could fit my wedding ring back over the knuckle after two years ;-/
