A panic attack usually occurs when you experience intense fear or discomfort which can intensify within minutes. You may experience a range of unpleasant physical symptoms, including breathing problems, a pounding or racing heart, stomach discomfort, tingling or numb hands, sweating, weakness or dizziness, chest pain, and feeling either hot or cold. These sensations can lead to feeling a loss of control.
Panic attacks may be triggered in response to a fear about a situation, or a place. At times, however, panic attacks may appear for no apparent reason. If you experience panic attacks, you may become persistently concerned about having further panic attacks.
