Throat Tightness: Causes and How to Tell Them Apart

How to tell the causes apart

Causes of throat tightness

Anaphylaxis

Anaphylaxis is a severe, fast allergic reaction to triggers such as peanuts, tree nuts, shellfish, insect stings, latex and medicines like antibiotics. The throat can swell and close. Epinephrine is the only first-line treatment; antihistamines are too slow. Even if symptoms improve after epinephrine, go to the emergency department, because symptoms can return.

Angioedema

Angioedema is swelling deep under the skin of the lips, tongue, face or throat. It can occur without hives. ACE inhibitor blood pressure medicines (such as lisinopril) can cause it, even after years of use. Hereditary angioedema causes recurring attacks. Throat swelling from angioedema is an emergency.

Anxiety and panic attacks

Anxiety tightens the muscles around the throat and causes fast breathing, which can create a feeling of choking or not getting enough air. In a panic attack, this comes with a racing heart, chest tightness, sweating, trembling and a sense of dread, peaking within about 10 minutes. The voice stays normal, and swallowing and breathing work.

Acid reflux

Stomach acid reaching the throat (GERD or "silent reflux") irritates the throat and can cause tightness, a lump feeling, hoarseness and chronic cough. See also lump in throat.

Throat infections

Strep throat, tonsillitis and viral infections make the throat swollen and sore, with a tight feeling on swallowing. A peritonsillar abscess causes severe one-sided pain, a "hot potato" voice and difficulty opening the mouth. Epiglottitis is rare but dangerous.

Other causes

• Muscle tension dysphonia: tight throat and voice strain with heavy voice use.
• Thyroid swelling (goiter or thyroiditis): pressure in the front of the neck.
• Eosinophilic esophagitis: food sticking and throat or chest tightness, often in people with allergies.
• Inducible laryngeal obstruction (vocal cord dysfunction): the vocal cords close when you breathe in, causing throat tightness and noisy breathing, often mistaken for asthma.
• Heart: rarely, angina is felt as throat or jaw tightness during exertion.

What to do right now

If you suspect anaphylaxis

1. Use an epinephrine auto-injector into the outer thigh, through clothing if needed.
2. Call 911 or your local emergency number.
3. Lie down with legs raised, or sit up if breathing is hard. Do not stand or walk.
4. Give a second dose after 5 to 15 minutes if symptoms do not improve and a second injector is available.

If anxiety is likely

• Breathe in slowly through your nose for 4 seconds, hold briefly, and out through pursed lips for 6 seconds.
• Sip cool water.
• Relax your shoulders, jaw and tongue.
• Remind yourself that you can speak and swallow normally, which means your airway is open.

How doctors find the cause

A doctor will ask about timing, triggers, medicines, allergies, voice and breathing changes, reflux symptoms and anxiety, and examine the throat and neck. Tests may include allergy testing, a flexible camera exam of the throat (laryngoscopy), a strep test, thyroid ultrasound, or endoscopy.

Treatment

• Allergic reactions: epinephrine for anaphylaxis, allergy referral, carrying two auto-injectors and an action plan.
• ACE inhibitor angioedema: stopping the medicine permanently.
• Anxiety: cognitive behavioral therapy, breathing techniques and sometimes medicines.
• Reflux: avoiding late meals, alcohol and trigger foods, raising the head of the bed, and acid-reducing medicines.
• Infections: pain relief, fluids, antibiotics for strep, and drainage of abscesses.
• Vocal cord dysfunction and muscle tension: speech therapy.

Frequently asked questions

Why does my throat feel tight?

Common causes include anxiety, acid reflux, muscle tension and throat infections. The most serious cause is an allergic reaction (anaphylaxis or angioedema), which comes on quickly and often with swelling, hives, voice changes or wheeze. That needs epinephrine and emergency care.

How do I know if throat tightness is from anxiety or an allergic reaction?

Allergic throat tightness follows a trigger within minutes and often comes with hives, lip or tongue swelling, a hoarse voice, wheezing or vomiting. Anxiety-related tightness comes with fear, a racing heart and fast breathing, while your voice, swallowing and skin stay normal. When in doubt, treat it as an emergency.

Can acid reflux cause throat tightness?

Yes. Acid and stomach contents reaching the throat cause irritation, tightness, a lump sensation, hoarseness and cough, often worse after meals or in the morning. Changing eating habits and acid-reducing medicine usually help within a few weeks.

Can anxiety make your throat close up?

Anxiety can make your throat feel like it is closing, but it does not actually block the airway. The sensation comes from muscle tension and fast breathing. Slow breathing usually eases it. If tightness comes with swelling, wheeze or voice changes, seek emergency care.

Is throat tightness a sign of a heart problem?

Rarely. Angina can be felt as tightness in the throat, jaw or chest, typically with exertion and easing with rest, sometimes with breathlessness or sweating. If throat tightness comes on with exercise or with chest pain, seek urgent medical assessment.
