Question 030: Knuckle pain

I am an advocate of using the first two knuckles to punch with, but when it comes to punching hard, flat surfaces such as the front or sides of the skull, or boards, striking with the last three knuckles is less likely to cause injury. When punching a flat surface with the first two knuckles, the two knuckles, and sometimes just the middle knuckle, strike the surface first and are injured. When punching with the last three knuckles, all three knuckles and the front of the fingers usually strike the surface together so they are less likely to be injured.

It would be best to have the hand checked by a doctor to make sure there is not an injury that should be medically treated. Good luck in future testings.
