I experience what I have been calling panic attacks about once a week, for about two months now. I am seeing a psychiatrist and he agreed with me that it is a panic attack. However, I was with a friend when I had a panic attack, though it was much shorter than mine usually are. This friend talked to her mother, who is a registered nurse, about my symptoms and she thought it more than a panic attack. My symptoms were as follows. I was very stressed that day and had been very overwhelmed. Then, my heart rate increased, I felt dizzy, so I sat down. After a few seconds, I was unable to move. After a while I started having a tremor in my right side, mainly the arm, neck and leg. My eyes were also twitching. This lasted about five minutes in total. Afterward, I was very tired and I still walked unsteadily. Does this sound like a panic attack? Or does it sound like something more?
