My 8 year old daughter got hit by baseball right in the middle of the chest about 3 years ago, but seemed to be unharmed.  She now complains about her "heart hurting" and we have noticed shortness of breath when she is playing.  Could this be related to this old injury?
Hi, Thank you for asking question on Chat Doctor. I do not think it is related to the past injury. Shortness of breath is really a matter of concern. Better consult pediatrician for proper diagnosis and treatment. Hope this answer will serve your purposeless feel free to ask any more queries if requiredTake care Chat Doctor. V.
