I know that feeling when you know straight away that a doctor is going to be no help and you might as well have set fire to 60 bucks

I was wondering about your echocardiogram results and how the right side pressures were.... thinking pulmonary hypertension or embolus, but I guess they have ruled that out. I wonder if you could ask to be referred to a specialist i.e cardiologist? I have looked after patients with heart disease who present with similar symptoms, especially women who have been fobbed off for some time prior to hospital admission. I don't mean to alarm you, but you know something is not right. I'd keep pushing for answers x
