Middle knuckle prominence?

I am a 16 year-old female, who weighs 115 lbs and is 5’3”. I have no past medical conditions & no medical records. I take no medication. About 2-3 weeks ago, I punched a wall repeatedly several times for a duration of around 10 minutes each day for like a week. I initially got knuckle bruising, which was expected, and a bit of swelling and pain, but again, was expected. (Note: I did not have padding on my hands, no bandages or anything while punching) After the bruising and inflammation subsided, my middle knuckle appeared more prominent and stuck out more. The bruising on my middle knuckle seemed like it went through to under my knuckle, near my palm, before all of the bruising subsided.

I have no pain or difficulty using my hands, so I’m not sure what it is. This cannot be normal though, since knuckles do not protrude this much. I assumed it wouldn’t be boxer’s knuckle, but I’m not sure if that can happen without pain or difficulty curling and uncurling my fists.

When there is repeated trauma to a joint the body will send in bone matrix material as a protective measure. This will take the form of mineral and bony deposits in the joint, in your case the metacarpal or knuckle of your hand. Since the inflammatory process has subsided, you no longer have pain or stiffness. However, the bony prominence will remain. It remains to be seen if this prominence will eventually retract. Probably not. In the future, I would recommend getting a softer punching bag.

It is clear that you injured your knuckle (I don't think you need an expert to tell you that, though). If you really want a diagnosis, you should contact your health care professional. An x-ray (or even better--an MRI) examination would be helpful in assessing the extent of your injury and a prognosis.
