Good afternoon, I am new here. I posted a similar question on a related site and did get good help with what to do in case of another panic attack or similar issue. I have never suffered regularly from the attacks, and what recently happened was only the second in my memory. It took place when I was explaining to someone who was injured a few days ago how to use crutches properly. He asked as I have recovered from a broken leg (some time ago). I had no problem helping. When I started to handle the crutches I found myself first experiencing the 'this is like riding a bike' feeling' and had no problem with using them. That started me thinking about my own recovery years ago and that's when the dizziness and wanting to vomit started up. I have no idea how or why this happened. Does anyone have any idea or can relate? I think I know what to do if if something similar happens, but I don't understand how or why this reaction happened. There was absolutely nothing in the environment that as threatening or presenting a danger. Thanks.
