My 8Y/O son has been to the doctor recently because he complained about pain on his chest. The doctor noticed a little lump
/bump with redness right on the sternum
area. It was really painful for a day or so. The pain has subsided, and the redness gone away. However, it is still slightly painful to the touch. He has no fever, loss of appetite , etc. They performed Xrays, and blood tests, and ruled out a bone infection, and fracture. They think its probably just a sprain, strain or hematoma.
