Don't know if They did a PTE study with her C.T. but she could have a blood clot the syptoms you describe sounds like a clot also could be heart related , I would get her to somebody that knows whats going on , don't play with heart issues or blood clots I work in CT and see this stuff all the time . Has she taken any nitroglycerine ? If not get her some and see if her pain lets up .
