I have a son who is eight years of age with no noted health history.  He has complained of \"pinching\" in his chest, unrelated to activity, eating, breathing, touching. It usually is not associated with any other symptoms.  It lasts for a second then goes away. I plan to call our pediatrician today to make an appointment.
Respected user, hi I evaluated your query thoroughly.*Causes may include gastric upset, minor respiratory ailment through any bacterial / viral infection.*Usually seems non-significant clinically, but still any underlying minor issues should be ruled out by physical examination & if necessary diagnostic tools Hope this clears your query. Thanks for using Chat Doctor & keeping trust in our medical services. Wishing him happy healthy life ahead. Regards.
