dynhamik,

It sure sounds like a panic attack to me. I have had them. They can be just a few seconds to even hours long. If they last, if you can, get your blood pressure tested. We keep a home blood pressure kit handy. I have experienced very high BP during a panic attack.

You can check your pulse easily at the time of the event. If it returns to a normal level soon after, it is likely a panic attack. There are a variety of trigger for panic attacks. It can be difficult to identify the trigger without taking not of all of the stimuli at the time.

My best to you.
