toomanyshoes- did they check for pericarditis? My DH had similar symoms, we thought he was having a heartattack but thats what it was. His was worse when he lay down ( ? I think? or the other way round??) which is a common symptom. Hope you get an answer soon x
They thought it might have been that but again all the tests said no.

One of the tests I had was positive/higher than usual which indicates blood clots, but when the CT didn't show anything they couldn't tell me why the blood test said yes. All I got was "well there could be 100 different reasons".......
