Heart Symptoms Flushing

Are the symptoms of a panic attack similar to anything else?
1) palpitations, pounding heart, or accelerated heart rate
2) sweating
3) trembling or shaking
4) sensations of shortness of breath or smothering
7) nausea or abdominal distress
feeling dizzy, unsteady, lightheaded, or faint
13) chills or hot flushes
These are some of the symptoms of panic attacks. I’ve had a panic attack before, but today was quite different, VERY dizzy and the worst headache I’ve ever had. Could this be anything else, other than a panic attack? I was not fearful at all – which is usually required for the diagnosis.
Anything similar to these?
similiar to heart attack symptoms, in fact, many people who experience their firt panic attack often mistake it for a heart attack – get a feeling of chest pressure and often it comes right out of nowhere.
