Hi, my 14 year old son has been experiencing severe chest pain and light headedness. I wasn t concerned until he had me feel his chest when he was having an episode . I could feel and see his heart beating rapidly and strongly for the lack of a better word. I took him to our family doctor and she assured me it was probably just anxiety although my son said sometimes the pain wakes him while he is sleeping. Once the pain was so bad he was crying and he says it is radiating into his shoulder. The doctor had an EKG performed. I don t know the results but I insisted on him seeing a cardiologist. Am I over concerned? Under? He has an appointment this Thursday with a pediatric cardiologist, should he be seen sooner. This has been going on for some time but has really become more frequent in the past month.
