Hi this is about my 14 year old daughter for about a year now every time my daughter runs no matter how short she gets a really stabbing pain inbetween her shoulder blades and feels really quite sick with it, also gets a shortness of breath, she says it is so sore that she has to stop suddenly and lie down, 1 time she did vomit, as i say this is only recent shes felt like this, i hope someone can bring to light what could be causing this, thankyou, julie x.
