Dry Cough and Chest Tightness
A dry or unproductive cough doesn’t produce mucus. A tickling sensation in the throat can make you have a dry cough. Dry coughs can come on after a cold or flu or if you have COVID-19. Other conditions like GERD, heart failure and lung cancer can cause chronic dry coughs. You may also have chest tightness with a dry cough.
What is a dry cough? A dry cough doesn’t produce mucus. Because there isn’t mucus blocking the lungs or airways, nothing comes out when you cough. This lack of mucus (phlegm) makes it an unproductive cough.
What’s the difference between a dry cough and a wet cough? A cough is your body’s way of clearing the lungs and airways of irritants so you can breathe better. When you have an illness that affects your respiratory system, you may cough up mucus. This is a wet cough. Healthcare providers consider a wet cough to be productive because it clears phlegm (mucus) from the lungs and airways. If too much phlegm builds up in the lungs, you may become short of breath and develop other problems. When you have a dry cough, nothing comes up. This unproductive cough doesn’t open up the lungs or air passages.
What are the symptoms of a dry cough?
With a dry cough, you may feel a tickling sensation in your
throat. You may try to clear your throat by coughing. As you forcefully expel
air, your throat can become irritated and dry. You may develop a sore throat.
Why does my chest hurt when I cough?
When you have an unproductive dry cough, you essentially
cough up air. A dry cough that is very vigorous or lasts longer than three
weeks (chronic cough) can strain your lungs or chest muscles. You may develop
chest pain with the cough.
Most people have a feeling of chest tightness with a dry
cough. You may feel a squeezing sensation in the chest or pressure, like
there’s a weight on your chest.
Sudden, unexplained chest pain can be a sign of a heart
attack. You should seek immediate medical care.
Do colds, flu and COVID-19 cause a dry cough?
Colds and flu tend to cause wet, productive coughs when
you’re sick. Later, dry coughs may linger during recovery.
It can take a while for inflammation from respiratory
infections to go away. During this time, the lungs and airways may be extra
sensitive to inhaled irritants. This sensitivity can make your throat more
ticklish, causing you to cough.
Most people who get sick with COVID-19 have dry coughs — not
wet coughs like with the cold or flu. However, wet coughs can also happen with
COVID-19 infections. Your healthcare provider may recommend a COVID-19 test to
identify the cause of the cough.
What other conditions cause dry coughs?
Other conditions that cause dry coughs include:
Allergies, asthma or exposure to chemicals and irritants.
Bronchitis.
Croup (in children).
Gastroesophageal reflux disease (GERD) or laryngopharyngeal
reflux.
Side effects of medications, such as those that treat high
blood pressure.
Postnasal drip (upper airway cough syndrome).
Pneumonia.
Smoking.
Vocal cord dysfunction.
Whooping cough (pertussis).
Can a dry cough be a sign of a more serious problem?
Rarely, a dry cough indicates a more serious, potentially
life-threatening health problem. You should see your healthcare provider if you
have concerns about a cough.
A chronic dry cough may be a symptom of:
Chronic obstructive pulmonary disease (COPD).
Cystic fibrosis.
Heart failure.
Lung cancer.
Pulmonary embolism.
Sleep apnea.
Tuberculosis.
How can I treat a dry cough and tight chest?
Most dry coughs clear up when you treat the underlying
cause. Over-the-counter (OTC) cough medicines aren’t usually that helpful. And
children younger than 4 years of age shouldn’t take any cough medicine because
of the risk for serious side effects.
These at-home remedies can help:
Drink plenty of liquids to stay hydrated. Try hot tea or
water with honey and lemon to soothe irritated airways.
Suck on cough drops or hard candies. Sucking on a hard
lozenge promotes saliva production that soothes the throat. But don’t give
cough drops or hard candies to children under 4. They can choke.
Take a spoonful of honey. Studies show that honey stops
coughs as well as (or better than) most OTC cough medicines. Your healthcare
provider can recommend the right amount of honey based on the ill person’s age.
Never give honey to a child under 1 year of age. In babies, honey can cause
botulism.
Use a humidifier. A cool-mist humidifier puts moisture into
the air. This extra moisture soothes nasal passages and sore throats and eases
dry coughs. You can also get more moisture by taking a steamy shower or hot
bath.
How can I prevent dry cough and chest tightness?
These steps may lower your chances of having a dry cough:
Avoid irritants and allergens like chemicals, mold and
fragrances.
Practice good hygiene and wash hands frequently to prevent
respiratory illnesses.
Quit smoking and avoid secondhand smoke.
