Yes!!

I have had extreme shortness of breath and chest pains since the accident twice now, both times have landed me in an ambulance because they thought I was having a heart attack.

Both times my results came back normal. And it wasn't a panic attack because unfortunately, I KNOW what they feel like.

I wonder if I had not been breathing deeply enough which led to lack of oxygen on my already confused brain...

It was a very scary experience both times.
