 [ Symptoms ] pain in chest with palpable lump no diagnosis can be made [ Disease ] hi let me mention here that its rather unusual site to have such swellings though it doesnt seem to be related to heart or lungs but swellings related to underlying bone costal cartilage can occur see if its painful and sore on pressure does it move or is fixed and the local temperature whether its warm or cold like a normal skin a warm swelling indicates an underlying infection thanks
