My first "panic attack" 6 months ago lasted 1 whole hour, my whole body was jerking as in I was having convulsions (legs, arms, chest/back), and I was feeling myself about to faint, but at the same time I was still conscious, even though had the feeling to be very high.
The seconds one, 3 weeks ago, lasted 2h30min, and this time, my whole body was stiff! I could not even talk anymore, and could only breathe with my noise. My whole face was tingling and I could not even open my mouth. Both my hands were curled up and no one could open/release them until the end of my attack.
For both of them, I was able to reach the A&E on time. Did you experience the same symtoms?
