I went to A&E (ER in the UK). They did two ECGs and said they thought I was ok.
A month a go I discovered I'm borderline anemic (a consultant hematologist diagnosed this) but I've been told chest pain unrelated because that only happens with severe anemia.
God knows what's wrong.
I was sitting in my car, and it feels like a fist pushing into my chest.
Your body is desperately trying to tell you something. Listen to it.
