So I broke my 4th and 5th metacarpal during a fight which right after I went to er and got xrayed and a split put on. Wore a cast for 5 weeks and now I feel like my finger knuckle is damaged as well. I had to buddy tape it to my middle finger otherwise it feels like nothing is holding it but the skin around it. I can touch all around my knuckle and feel no pain I also don't feel numbness so I am so confused as to what could be wrong with my finger.

Keep in mind I can move my finger up and make a fist so tendons should be good.
