Yes helpingme I do and it is the weirdest feeling ever...you are the first person that has actually put it into the same words and it is almost impossible to discribe to a doctor. The first time it happened I was driving home from work and thought I was having a heart attack I actually drove straight to the ER instead of home. They kept me there for 3 days and found nothing except panic and anxiety. Now everytime I get a pain in my chest I will get the same gushing feeling and instantly think "Heart Attack". I think it is the adrenaline that we feel gushing thru our system, at least that is the only thing i can come up with because when we start to panic the body releases the adrenaline.
I have had all kinds of test and they tell me all is normal but even knowing this if i have a pain in my chest I still have a tendency to panic and bam here comes the gushing.
You are not alone and thanks to you I am now not alone.
