Anxious soul, I'm right with you. It's a very scary feeling especially when it happens a lot in one day. My dad researched and told me to try hard cardio regularly since maybe my heart is not working...
Ah what a relief!! I am a 21 yr old female and have been having this weird "sensation" since I started having anxiety issues a year ago. And I also cough! It's almost like a reflex to stop it. Thanks...
