My father had a heart attack 5 years ago. He didn't have any pain but he just couldn't get his breath. He went to the emergency room and is still alive now.
As someone with health anxiety I can make myself feel symptoms of things I'm worried about. I tend to not get checked out because I know it's probably my own mind so things like this help people like me distinguish between the two so I'm not at the doctor or E.R at every little thing. So thank you
