""not enough time""

Having been referred for blood tests to establish reasons for breathlessness I was asked to undergo ECG, chest x ray and several blood tests. Despite the ECG only being undertaken with me laying down (when typically I'm fine!) and one of the blood tests coming back abnormal, I was told they were 'ok' . I asked, if so, what would be done to identify why I was suffering breathlessness and was told they "didn't have time" to explore further. They seem disinterested in anything except the straightforward. And ever since a trainee doctor changed my blood pressure tablets some weeks ago and my BP has dropped to 120/65 and I keep almost feinting, But no follow up. Such a change from 20 years ago. I'm moving to Weedon.
