Panic attack symptoms are Pains in the chest, Sweating, Shallow breathing or Panic breaths, Tingling sensation and numbness, Worrying thoughts, Thinking you are having a heart attack basically when its all in your head. My older brother used to suffer with severe anxiety its horrible he'd run out of the room sometimes because he thought he was having a real heart attack, but nothing was wrong with him he was perfectly healthy. Hope that helped.
