My 9 year old started boxing regularly for the past couple of months, she goes twice a week for a couple hour sessions. Her right hand hits wicked hard and she has been experiencing pain sometimes from the force of the blow. She doesn't have any problems using her hand for any other punch but when her straight right or overhand right connect with a loud report sometimes she winces a bit. Her hands are wrapped and she is wearing gloves. I look at her hands and they are not obviously bruised but she sometimes says it is sore to touch them. Coach has just told her not to hit full force for the time being. This is her first time seriously training striking is it possible that this is something that will just go away with time?
