|A panic attack typically lasts ten minutes, or, somewhere between 1-20 minutes.
More severe panic attacks may form a series of episodes waxing and waning every few minutes, lasting for a period of up to two hours, only to be ended by physical exhaustion and sleep.
In conditions of chronic anxiety, one panic attack can roll into another, leading to nervous exhaustion over a period of hours or even days.
Many medical illnesses can cause symptoms that mimic panic attacks, including heart disease, asthma, cerebrovascular disease, epilepsy, hormone abnormalities, infections and disturbances in levels of certain blood chemicals.
Do you get similar attacks during day, too?
