Panic Attack or Something Else?

Heart racing, shortness of breath, chest pressure, shaking, and dizziness can happen during a panic attack. The same symptoms can also appear with heart or lung problems and other medical conditions. You cannot safely decide from one episode that anxiety is the cause. Call 911 for warning signs, and discuss a first episode with a doctor even if it passes.

What a panic attack can feel like

A panic attack usually begins suddenly and becomes intense quickly. Symptoms often reach their strongest point within minutes before the wave gradually eases. The experience may be brief or continue much longer, and you can feel drained afterward.

Possible symptoms include:

a fast, pounding, or unusually noticeable heartbeat;
shortness of breath or tightness in the throat;
shaking, sweating, or dizziness;
tingling or numbness in the hands or face;
a sense that you or your surroundings are unreal;
fear of fainting, dying, or losing control.

These strong physical sensations can result from the body's alarm response. Your body prepares for action, but there may be nowhere to direct that energy. The sensations then seem like proof that something dangerous is happening. Fear raises tension, and tension makes the sensations stronger. This cycle explains why an episode can escalate so quickly. It does not identify the cause.

Breathing patterns can add to the experience. Fast, shallow breathing can cause tingling around the mouth and hands, dizziness, and a detached feeling. Those sensations can be frightening and often ease as breathing settles. Still, you should not assume that breathing is the explanation for new or severe symptoms.

When you need urgent help

Call 911 or go to the nearest emergency department if you have:

new, severe, or persistent chest pain or pressure, especially if it spreads to an arm, your neck, back, or jaw;
serious difficulty breathing;
fainting or loss of consciousness;
blue lips or blue or gray skin;
trouble speaking or sudden weakness on one side of your body.

Do not wait to see whether these symptoms disappear. Do not try to settle the question by yourself while they are happening. It is reasonable to seek urgent help when you cannot tell whether an episode is panic or a medical emergency.

What you cannot assess by yourself

Certain patterns can suggest an anxiety response. An episode may occur in similar situations, follow intense stress, and rise and fall like a wave. Previous medical tests may also have been reassuring. These details are useful, but they cannot rule out a physical cause.

Be especially cautious if you have a known heart or lung condition, recently had a procedure, were unable to move around for an extended period, or are experiencing these symptoms for the first time. A clear change in a familiar pattern also deserves medical attention. Panic is considered after other reasonable explanations have been reviewed, not instead of reviewing them.

Normal test results do not mean that you imagined the symptoms. They mean the cause may lie elsewhere. An anxiety response is a real process in the body, even when testing does not find a heart or lung problem.

What to tell a doctor

Write down a short account before your visit. Note when the episode started, what you were doing, which symptom came first, how the sensations changed, and what provided any relief. Details are easy to lose once you are sitting in an exam room.

Tell the doctor about medications and supplements you take, caffeine and alcohol, recent sleep, existing health conditions, and similar problems among close relatives. Say what you fear might be happening. Ask what the recommended tests examine and what their results can or cannot rule out.

When to seek mental health care

If medical assessment does not show a physical cause and the episodes keep returning, consider speaking with a psychologist, therapist, or psychiatrist. Avoidance is a clear reason to seek help. You may stop driving, shopping, exercising, or being alone because you fear another episode. Avoidance can bring short relief while gradually shrinking your daily life.

Between appointments, you can record episodes and use short tension regulation exercises, including the self-help tools in HelpClinic. A record may help a professional see patterns, but it cannot diagnose the cause or replace medical assessment.

If you have thoughts of suicide or fear you may hurt yourself, call or text the 988 Suicide & Crisis Lifeline, available 24/7. Call 911 or go to an emergency department if you are in immediate danger.

Frequently asked questions

How can I tell a panic attack from a heart problem?

You cannot safely tell from the sensations alone because heart racing, shortness of breath, and chest pressure can occur in both situations. Call 911 for new or severe chest pain, serious trouble breathing, fainting, or pain that spreads. A first episode should be discussed with a doctor, who can decide whether you need medical tests.

How long does a panic attack last?

A panic attack usually starts suddenly, becomes most intense within minutes, and then gradually eases. The full episode may last from several minutes to considerably longer. Physical symptoms that continue, especially chest pain or difficulty breathing, need medical assessment. Do not wait for them to pass if they are severe, new, or different from previous episodes.

Do I need to go to the emergency department for a panic attack?

Not every panic episode requires emergency care, but warning signs do. Call 911 or go to an emergency department for severe chest pain, major difficulty breathing, loss of consciousness, blue lips or skin, trouble speaking, or sudden weakness on one side. When you are unsure whether the cause is panic or a medical emergency, seek urgent help.
