i and my friend punch walls with our right hand and the knuckles are definately bigger than my left. is this swelling or are the bones/knuckles really getting bigger. cuz i stopped this and my right foot knuckles still is big. really big. (we play bloody knuckles daily)Why does punching walls manufacture the knucles bigger?
Maybe your knuckles are trying to make up for you have such a small brain.
Doing what you are doing is DANGEROUS...not to mention that you are breaking down vital cartilage contained by your joints. You are resourcefully on your way to have early arthritis.
Your bones aren't any larger...you probably basically have swelling within the joints, or possibly some torn ligaments and tendons. I HIGHLY suggest you and your friend playing a "game" i.e. more mature and smaller amount destructive to your body.
probably swelling. and if you think they stay big merely because and they're always close to that it might just be surrounded by your head..
i freshly dont know who in their right mind punches walls for fun..
If you rupture a sagittal decoration, which you sound close to you are on your way to possibly doing, you can appendage up with a ineradicably deformed finger. Try hitting something softer that isn't attached to another person.
Well, I'm not a nurse, but my guess is, undermined tissue?
