What are the main symptoms of panic attacks?

From my personal experience, i'd say obviously an overwhelming amount of a panic feeling which is kind of like fear, heart racing/Difficulty in breathing, very tensed up muscles and the need to "get away" from whichever situation you are currently in. Although a lot of people can have more, less, or different symptoms.

Panic attacks symptoms vary between different people. The most commonly shared ones are the shortness of breathe, shaking or trembling, sweating, feeling like you have an upset stomach, possible chest pain. Aside from the physical symptoms, mental symptoms feel like you're detached in your situations and you need to get out. If you feel like you have these symptoms it is important to get help so you can deal with these.

Sudden fear, palpitations, hand-shaking, and nervousness. Almost sufferers, feel that unexpected event will be disastrous and terrifying.

Sweating, shaking, heart palpitations, nausea, difficulty breathing, hot flashes, feelings of dread or a feeling of oncoming doom.

-Trouble breathing or hyperventilating - Increased heart rate - Thoughts that cause a sense of panic - Dizziness

In my experience and from what I have heard from others, the main symptoms of a full blown panic attack are the following: shortness of breath or hyperventilation, a racing heart, chest pain or discomfort, trembling or shaking, feeling unreal or detached from your surroundings, nausea, upset stomach.

Shortness of breath, heart palpitations/racing heart, trembling/shaking, nausea, upset stomach, dizzy/lightheade/faint, and chest discomfort. These are just some of the common symptoms.

For me its flashbacks, hyperventilation, rapid heart rate, and shaking. I've thrown up maybe 2 or 3 times. Afterwards I just feel completely exhausted like I just ran a marathon.

Feeling like you can't breathe, not being able to control your emotions. Personally I also get a weird symptom where I feel like everything touching me is a bother, and if I'm safe and alone all my clothes comes off till I calm down. It's frightening but you can get past it.

When you experience a panic attack, you might start shaking and hyperventilating. Feeling like you have to force yourself to breathe or become as small as possible
