I always get a tightness in my throat like I am being strangled. My chest hurts like I am having chest pains and I get dizzy....most of the time I dont feel nauseous but I do if I am having a panic attack because I already am nauseous then its a completely different panic attack when my heart starts racing and my fingers and face get tingly and my face gets hot and then my mouth goes dry (but I think that is because I breath out of my mouth when I dont feel good)
