My 9 yr old son has been having periodic chest pains for about 3 wks now. There is not really a pattern as to when it happens. Just comes out of the blue and after about 30-45 secs they go away. We seen his pediatrician and took her advice and cut out caffeine and have tried to stay away from foods that would cause the indigestion she suggested it was, but it has not changed. Now and I have no idea if it is related but he has been vomiting. Friday he was vomiting, Saturday he was fine and then today started vomiting again.
