my six year old son has been complaining of his heart hurting the past couple of months. He does have asthma but has not needed his inhaler for months. No shortness of breath. He started playing tball a few weeks ago (the pain started before) and a few hours after his game the other day was crying in pain. We figured a muscle strain but then thought about the fact that this isn t the first time he has said his heart hurts. He does not and has not been sick during these complaints. The morning after his complaint the other day after T-Ball he complained the back of his neck hurt. He slept 8 hours that night but an hour after being up was fatigued and fell asleep in the car. He woke up from napping screaming in pain that his arm hurt. After 5 or 10 minutes he was fine. We have another son with Congenital Heart Disease so we do have a family history of heart disease. Hoping it s nothing. Could be his asthma or possibly acid reflux maybe? Sleep Apnea also runs in the family as well as diabetes.
