Okay so this just happened. I felt a surge of intense nausea like I was gonna be sick then it stopped happened again stopped for longer than happened again I haven't actually gotten sick but the surges also feel like I'm disconnected for a few seconds and almost like and electric shock through my body that starts at my head and goes down my body. Can this be cause by panic?! Can a panic only last a few seconds?! Point is I'm very worried now
