Whilst I agree GP was probably abrupt, if he genuinely thought you had a PE it can be potentially fatal if left untreated. A D-Dimer is non specific but it could have been ruled out by a CT scan if the chest. (CTPA). Just be thankful it was not a PE and concentrate on getting well. Xxx
The blood test for a pe (d-dimer) is very sensitive but not specific. Lots of things can cause it to go up (including pneumonia) so in the op case it wouldn't have been helpful at all. It's only really of value if it's normal when it virtually rules out a pe.
A simple blood test (dimmer) would have provided pretty much certainly of you had a chance of having a blot clot or not. If they thought you had a Blood clot on your lungs you would have a needed a CT scan as they dont show up on xrays, and they wouldnt have let you leave without knowing for sure if they suspected this.
Having had a huge blood clot and now hugely paranoid!! so lots of hospital visits, this is the first test they carry out (in december most recently in dubai, this is first thing they did and also in Australia and UK)
I was having terrible rib and chest pain and because of history they suspected PE, but the blood test ruled this out instantly.
I have discharged myself once after waiting 5 hours, my phone died andi had no way of contacting the person who had my daughterand all my family and dds dad live abroad! The hospital was rightly fuming with me and i had to sign full disclosure to say i was leaving against medical advice.
I dont think your doctor was unreasonable, i think he was caring for your wellbeing and my doctor is just as brusk with me! but i would rather he be stern than not give a **.
Your first post does make it sound like you discharged yourself from A&E before they could make a proper decision . I don't think there's anything to complain about although he does sound a bit brusque , perhaps he was having a bad day .
So the GP thinks there's something pretty seriously wrong with you, takes appropriate action by referring you to hospital, and after some foot stamping on your part (I want to go home), you become more unwell, and go back to that same GP and you're surprised that he's annoyed that you've not taken his appropriate advice?
