Congestion Symptoms

Spring has sprung. The leaves and flowers are in bloom, which can be a beautiful sight, until your eyes seem almost swollen shut and you can hardly breathe through your nose. You've got a severe case of a "stuffy nose" or nasal congestion.

You've been buying the drugstore out of Kleenex and allergy medicine and checking the pollen score online daily. But maybe it's not just allergies. Maybe it's caused by a viral or bacterial infection that's only aggravated by allergies.

Nasal congestion, which causes that chronic stopped up nose, is one of the most common conditions people suffer from. It is also highly treatable if you recognize its symptoms and treat it the right way.

Let's talk about what nasal congestion can mean and how to know if you have a serious infection causing your discomfort. [1,3]

Common symptoms of nasal congestion are:

  • Being unable to breathe through your nose. [2]
  • Feeling like there is something in your nose. [1]
  • Clear or yellow discharge from your nose. [5]
  • Clear or yellow discharge in the back of your throat. [5]
  • Cough, especially when lying down. [3]
  • Headache. [3]

More serious nasal congestion symptoms, especially in kids include:

Congestion Causes Overview

Most nasal congestion symptoms are caused by viral infections of the upper airways. Allergies and inflammation of the sinuses (air-filled pockets in the bones of the skull) are common causes of nasal congestion as well. Congestion is rarely a sign of a serious illness, but, in rare cases, it can be caused by serious infections like pneumonia or bronchitis. Left to fester, these infections can seriously threaten life and health. Upper respiratory infections can lead to ear infections and pneumonia can be deadly if untreated. [1]

Infectious nasal congestion causes:

  • Viral infections: Probably the most common cause is the common cold. [2]
  • Bacterial infections: Especially sinus infections, these can lead to a stuffy nose and often a thick, yellow discharge from the nose. [3]
  • Influenza: Also caused by a viral infection, the flu can make your nose stuffed. [5]

Inflammatory and allergic nasal congestion causes:

  • Sinusitis: Although many cases of sinusitis are from an infection, the sinuses can be inflamed without an infection and cause severe headache and nasal congestion. This can be acute or chronic. [2]
  • Allergies: Whatever the cause, allergies can make your head feel like it is clogged and it will never get better. [2]
  • Chronic sinusitis: This condition is diagnosed when the nasal passages stay inflamed for 12 weeks or longer. This can be caused by infections or nasal polyps, growths in the nasal passages, or a deviated septum. [1,2]

Other nasal congestion causes:

  • Foreign bodies: Kids often attempt to shove foreign objects in their nose or may playfully "sniff" things they shouldn't — dirt, sand, flour, powder, etcetera—and this can lead to a foul-smelling situation typically stemming from one nostril. [1]
  • Deviated septum: The bone that separates the inside of the nose into right and left nostrils can bend toward one side and lead to chronic stuffiness and even polyps in the nose. [1]
  • Irritation: Dry air, smoke, and chemicals can all lead to congestion. [1]
  • Overuse of decongestants: Abusing nasal decongestants can lead to a "rebound" stuffy nose that is worse than the one you started with. So,use these only as directed. [1]

A.I. Health Assistant Causes for Congestion

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced congestion. This list does not constitute medical advice.

  1. 1.Common Cold

    The common cold is a viral infection of the upper respiratory tract.

    The common cold resolves within 7 to 10 days.

    Top Symptoms:
    fatigue, headache, cough, sore throat, congestion
    Symptoms that never occur with common cold:
    being severely ill, severe muscle aches, rash, severe headache, sinus pain
  2. 2.New - Onset Seasonal Allergies

    Allergic rhinitis, is an overreaction by the immune system to allergens in the air. While pollen often causes allergies, other culprits include dust, animal dander, and mold.

    Allergies are often seasonal.

    Top Symptoms:
    sore throat, congestion, cough with dry or watery sputum, mucous dripping in the back of the throat, fatigue
    Symptoms that never occur with new-onset seasonal allergies:
    fever, yellow-green runny nose, chills, muscle aches
  3. 3.Chronic Sinusitis

    Chronic sinusitis is an inflammation of the sinuses (hollow cavities behind the nose & cheeks) that lasts more than 12 weeks and can continue for months or years.

    Longer than 3 months.

    Top Symptoms:
    fatigue, headache, trouble sleeping, congestion, runny nose
    Symptoms that always occur with chronic sinusitis:
    chronic sinusitis symptoms
    Primary care doctor
  4. 4.Acute Viral Sinusitis

    Sinusitis is an inflammation of the sinus spaces behind the nose and cheeks. These spaces produce mucus, which drains into the nose. If the nose is swollen or if the mucus does not drain, this can block the sinuses and cause pain or infection.

    Symptoms should subside within 7-10 days

    Top Symptoms:
    headache, cough, sinusitis symptoms, sore throat, congestion
    Symptoms that always occur with acute viral sinusitis:
    sinusitis symptoms
    Symptoms that never occur with acute viral sinusitis:
    being severely ill
  5. 5.Acute Bacterial Sinusitis

    Acute bacterial sinusitis occurs when the sinuses become infected and, in turn, inflamed, which causes pain and other symptoms. The sinuses are air-filled cavities in the face that are generally clean and empty but when they're sick collect excess mucus and can become infected. When your symptoms are persisting for 10 days or more or are getting worse over time, it's more likely that you'll have a bacterial infection as compared to a viral infection.

    7-15 days

    Top Symptoms:
    fatigue, headache, cough, sinusitis symptoms, muscle aches
    Symptoms that always occur with acute bacterial sinusitis:
    sinusitis symptoms
    Symptoms that never occur with acute bacterial sinusitis:

Congestion Treatments and Relief

There are many effective home remedies for nasal congestion as long as you keep your therapies focused on moisture — not dry forms of nasal congestion treatment. Many people think you need to "dry out" a runny nose, but you really need wet heat and steam to sooth your nasal passages. [3]

Good remedies for nasal congestion symptoms include:

  • Drinking hot, steamy fluids (think hot tea). [3]
  • Staying hydrated. [3]
  • Humidifying the air, especially in your bedroom. [3]
  • Taking a long, hot shower or bath. [3]
  • Nasal rinses with saline solution or using a Neti-pot — salt water actually hydrates nasal passages. [3]

There are several over-the-counter medications and remedies that can help you feel less congested as well.

  • Decongestants. [3]

    • Pseudoephedrine pills. [9]
    • Decongestant nasal sprays — be sure not to over-use these or you will get worse. [3]
  • Acetaminophen or ibuprofen if your stuffiness is giving you a headache. [5]

  • Antihistamines such as Benadryl or loratadine. [10]

  • Nasal steroid sprays, helpful for chronic sinusitis and congestion from allergies. [11]

  • Minimize exposure to smoke and allergens. [1]

In the event you have a bacterial infection, which your doctor can diagnose, a short course of antibiotics is often needed. [1]

If you have a foreign body in your nose, obviously you need to seek medical care to have the foreign body removed. [1] Likewise, if your nasal congestion symptoms are chronic and possibly due to a deviated septum, that requires seeing an otolaryngologist (an ear, nose, and throat doctor) to discuss appropriate treatment. [1]

FAQs About Congestion

Here are some frequently asked questions about congestion.

What causes congestion?

Mucosal inflammation (inflammation of the inner lining of the nose) is the primary cause of nasal congestion. Congestion is described as the feeling of reduced airflow through the nose and a sense of facial fullness. [1] Inflammation of or around the nerves of the face can also lead to changes in sensation and altered perception of both taste and smell. [12] Reduced airflow can occur when inflamed and swollen mucosa (lining of the inner nose) block adequate drainage of the nose. [1,2]

What causes a stuffy nose?

A stuffy nose is caused by an increase in mucus creation by the nasal mucosa as well as swelling of the nasal mucosa. This increase in mucus and swelling can cause a blockage of the nasal pathway. It is often accompanied by an uncomfortable feeling of nasal fullness causing individuals to try to expel mucus from the nose by blowing into a tissue. It may be accompanied by the loss of taste or smell and increased pressure along the maxillary sinuses. [1,2,11]

What causes head congestion?

Head congestion or sinus pain is caused by moderate to severe rhinitis or congestion that causes blockage of the sinuses of the skull. The sinuses are empty spaces or cavities within the skull existing most notably behind the cheekbones. When they are blocked, because they are unable to drain, fluid builds up increasing pressure which often causes discomfort. Lowering one's head moves this fluid further irritating nerves and causing pain. [2,11]

How to reduce nasal congestion?

Nasal congestion can be reduced by decreasing inflammation or allowing mucus to leave the sinuses. Steam from tea, soup, or a warm shower moistens mucus membranes and heats and thins mucus allowing it to drain. In moderate cases of sinus congestion, nasal spray or oral decongestants, antihistamines, or intranasal steroids can be used to decrease inflammation and allow mucus drainage decreasing sinus pressure. [1,3]

How to relieve severe nasal congestion?

Severe nasal congestion due to allergies can be treated with antihistamines, which decrease production of mucus and inflammatory compounds in the body; [3] with intranasal steroids like mometasone, which decrease inflammation; [11] or with saline irrigation (saltwater nasal rinses.) [11] Non-allergic rhinitis can be treated with decongestants, either oral or nasal. [11] Additionally, pain may be treated with over-the-counter pain medications like acetaminophen. [11] Bacterial sinusitis which is severe and is accompanied by pus drainage from the nose may require prescribed antibiotics. [11]
