Hi, I have been boxing for a few months now, and I got some new wraps and gloves. My middle finger knuckle on one hand is always sore when I practice, and then for days after. It hurts like hell. It feels like it is just beneath the skin. Any idea what might be going on?
You are punching the bag repeatedly. The impact trauma is causing the pain. Make sure you are making a fist correctly and your hands are wrapped properly.
Check with an old timer at the gym, they are the best sources of information for these types of things.
