Tightness of the chest, brain fog, inability to stay still, feeling like a small electric current runs through my body all the time, sighing and feeling the need to draw a deep breath to get air, muscle tightness.
If I don't knowingly stop it, my body will start to rock back and forth.
The one I had that does not seem to be common was chills. I would get very cold on a hot summer day - I live in south US where the humidity & heat are crazy. I would wrap in blankets & be cold. Wear coat & hat in building in summer where others wore shorts in AC env. In morning I would wake up feeling like crap - a hangover-ish or flu-like symptoms, nausea at the thought of eating, at least until late in evening. Extreme fatigue. A few panic attacks. Extreme anxiety at something like a tooth cleaning at dentist.
Those are all typical symptoms of a panic attack. It feels like a heart attack for me and I feel like I need to get up and run....anywhere, just away from wherever I am at that moment....like I am in immediate danger if I don't leave wherever I am. I also get cold sweats, nausea, nervous ticks, and a ton of pent up energy.
