Panic attacks with little to no physical symptoms?

I've definitely had my fair share of anxiety stomach aches and clogged throats, but whenever I'm certain I'm having a panic attack, I seldom feel any of the physical symptoms. I'll have a shortness of breath and an elevated heart rate, but I'm seldom shaking, sweating, having a headache, and only a few times will I have a stomach ache. Can anyone else relate?
