Hello. I have posted about this before. I am too lazy to find the link for it, but here are the symptoms of a panic attack. You need four of them to be considered a panic attack:

-Shortness of breath or hyperventilation
-Heart palpitations or a racing heart
-Chest pain or discomfort
-Trembling or shaking
-Choking feeling
-Feeling unreal or detached from your surroundings
-Sweating
-Nausea or upset stomach
-Feeling dizzy, light-headed, or faint
-Numbness or tingling sensations
-Hot or cold flashes
-Fear of dying, losing control, or going crazy

Anxiety attacks, to me, is when I don't have any of the above symptoms, but I suddenly feel very anxious, usually for no reason. If I get these symptoms and extreme anxiety, then it's a panic attack. Hope this helps .
