The wonders the human body can withstand. Well mine finally sort of gave out. The knuckle on my middle finger is dislocating to the inside sometimes when I flex, this after punching bareknuckle. The swelling hasn't gone down and the frequency has decreased, but should I be worried about subluxation? The doc took an x-ray and sent me home, no questions.
I permanently ruined a knuckle doing a board break on a Karate test. Even after years, the soft tissue is never the same.
