My 9 year old goddaughter has come home from school. Complaining about chest pains in the left side of the chest. She has described it to me as a slightly sharp pain that comes and goes on a regular basis. She told me she has had pins and needles too in her hands and feet though she isn t experiencing it now. I m a little worried. She has had an ECG in the past and was okay with no detectable problem. However the pains still come and go on a fairly regular basis.
