Yep, I get it all the time mildly and sometimes really badly. I call those times "episodes".

I have been tested up the wazoo for everything and found healthy but I do have panic disorder. Doctor says its completely normal to happen and you can't die from it and that my heart won't just stop.

In spite of everything it is a good idea to see a physician to make sure nothing else is causing it.

I have found that deep belly breaths help.
