Finger Injury

Dr 8A- I was recently climbing and a small crimp, when there was a pop in my finger...  The best way I can describe it is that my finger caved in.  I did not let go, but my finger did. It has been hurting the same for the past 2 weeks, and there is some mild discoloration on the back of my knuckles.  Is it possible that I need surgery?  Would you suggest that I see a specialist? Thank you Jesse
