Sinus Infection: Everything You Need to Know

Spread the love

What is a sinus infection, or sinusitis?

The swelling or inflammation of the tissue lining your sinuses is known as sinusitis. The air-filled structures located inside your face are called sinuses. Allergies, bacterial infections, and viral infections can irritate them and result in them being clogged and fluid-filled. In addition to other symptoms like nasal congestion (a stuffy nose), this may cause pressure and pain in your face.

Rhinosinusitis is another name for sinusitis.

What are sinuses?

Four paired chambers in your skull are called sinuses. Sleek corridors link them together. The mucus from your sinuses escapes via the openings in your nose. This discharge aids in maintaining the cleanliness and absence of bacteria, allergies, and other pathogens from your nose.


Types of sinusitis

Based on the duration of the condition (acute, subacute, chronic, or recurring) and the aetiology (bacteria, virus, or fungus), we categorise different forms of sinusitis.

Sinusitis that is acute, subacute, chronic, or recurring

In fewer than four weeks, acute sinusitis symptoms (such as nasal congestion, drainage, face discomfort or pressure, and diminished sense of smell) appear. Usually, viruses like the common cold are at blame.

subacute sinusitis symptoms persist For four to twelve weeks,.

For at least 12 weeks, chronic sinusitis symptoms persist. Most often, bacteria are the culprit.

The symptoms of recurrent acute sinusitis return four or more times in a year and linger for little more than two weeks each time.

Viral and bacterial sinusitis

The majority of sinusitis instances are caused by viruses, similar to those that cause colds. Either bacteria can infect you after a viral sinusitis episode or bacteria can cause sinusitis themselves. You may have bacterial sinusitis if your runny nose, stuffy nose, and face pain don’t go away after 10 days. Your symptoms could appear to be getting better for a while, but they might come back worse than before. When treating bacterial sinusitis, decongestants and antibiotics often work effectively.

Fungal sinusitis

Fungi-induced sinus infections are typically more severe than other types of sinusitis. If your immune system is compromised, you are more prone to experience them.

How can I tell if I have a cold, an allergy, sinusitis, or COVID?

The symptoms of allergies, sinus infections, COVID-19, and colds are identical. It can be hard to distinguish between them. Usually, a common cold develops, peaks, and then gradually wanes. From a few days to a week, it lasts. Sneezing, runny nose, congestion, itchy eyes and nose, and postnasal drip (mucus in the throat) are all symptoms of nasal allergies. Typically, they don’t provide the same level of face discomfort as sinus infections. Fever and dyspnea are two further symptoms that COVID-19 can induce.

Allergies, COVID, and colds can all lead to sinus infections. For some viral illnesses, such as COVID-19 and the flu, you can get tested by a healthcare professional or do it yourself.

Symptoms and Causes

What are the signs and symptoms of sinusitis?

Typical signs of a sinus infection consist of:

  • mucous streaming down your throat is known as postnasal drip.
  • runny nose with a green or yellowish mucus buildup.
  • blocked nose.
  • facial pressure, especially on the forehead, eyes, and nose. If you tilt your head or stoop over, this might develop worse.
  • your teeth are hurting or under pressure.
  • ear discomfort or pressure.
  • A fever.
  • unpleasant taste in your mouth or unpleasant breath (halitosis).
  • Give it a cough.
  • ache.
  • tiredness.


What causes sinus infections?

Sinusitis can be brought on by viruses, bacteria, fungus, and allergies. Certain factors that might cause sinusitis include:

  • common cold.
  • Influenza (the flu).
  • microorganism called Streptococcus pneumoniae.
  • The influenza bacterium Haemophilus.
  • bacteria called Moraxella catarrhalis.
  • seasonally and nasally allergic.

What are the risk factors for sinusitis?

Sinusitis is more common in certain persons than in others. Risk elements consist of:

  • allergy of the nose.
  • The asthma attack.
  • Nasal polyps.
  • Septum a deviation. Your nose is divided by a tissue line called the septum. A deviated septum narrows the airway on one side of the nose because it isn’t straight. This can result in a blockage.
  • An impaired defence mechanism. This may result from specific drugs or diseases like HIV or cancer.
  • smoking

Does sinusitis spread easily?

By itself, sinusitis is not communicable. However, the bacteria and viruses that might cause it are. Don’t forget to wash your hands well, stay away from ill individuals, and cough or sneeze into your elbow.

What happens if you don’t treat sinusitis?

Sinusitis usually clears up on its own, so treatment is not necessary. Rarely, untreated sinus infections can develop into infections that are fatal. This occurs when fungus or bacteria infiltrate your eyes, brain, or adjacent bones.

Diagnosis and Tests

How will I diagnose a sinus infection?

Medical professionals identify sinusitis by looking at your medical history and symptoms. A medical professional will examine your throat, nose, and ears for swelling, drainage, or obstruction. An endoscope is a tiny, illuminated device that they could use to examine the inside of your nose.

Your basic care physician could also recommend a specialist, such as an otolaryngologist (commonly known as an ENT, or specialist in the ears, nose, and throat).

Specific examinations to identify sinusitis

Your doctor may prescribe some tests to identify a sinus infection, such as:

A nasal endoscope.

Nasal wisps. Your healthcare professional could take a fluid sample from your nose using a stick with a soft tip. They will check it for viruses or other microorganisms that might be the source of your symptoms.

Imaging. Your doctor may occasionally request a computed tomography (CT) scan in order to have a better understanding of the condition inside your sinuses.

Allergy examinations. Your physician could test you for allergies if you have persistent sinusitis to see whether they are the cause.

Autopsy. An occasional sample of tissue from your nose may be taken for testing by a professional.

Management and Treatment

How is sinusitis treated?

Various therapy methods are available for sinusitis, dependent on the severity and duration of symptoms. A sinus infection can be managed at home with:

  • Softening agents.
  • over-the-counter (OTC) allergy and cold remedies.
  • saline nasal rinses.
  • consuming a lot of liquids.

In the event that sinusitis symptoms don’t go away after ten days, a doctor could recommend:

  • antibiotics.
  • either topical or oral decongestants.
  • Intranasal steroid sprays were prescribed. (Using over three to five days is not advised; using over-the-counter sprays or drops might worsen congestion.)

In order to treat chronic sinusitis, providers prioritise treating the underlying illness. Therapies may consist of:

  • sprays of intranasal steroids.
  • oral medications or topical antihistamine sprays.
  • antagonists of leukotrienes, such as montelukast.
  • surgery to address fungal infections, polyps, or structural problems.

Which drugs work best for sinus infections?

Which antibiotic your doctor recommends for you depends on your particular circumstances, assuming you require one. Among the alternatives are:

  • Amoxicillin/clavulanate augmentin.
  • Streptomycin.
  • D-cyclosine.
  • Levofloxacin.
  • Celafexime.
  • In cefpodoxime.
  • Clindamycin.

Are alternative and complementary therapies effective in treating sinusitis?

The discomfort, pressure, and drainage associated with sinusitis may be lessened by acupressure, acupuncture, or face massage. Find out if these treatments might be beneficial for you personally from a provider.

Do all sinus infections require antibiotics?

No. Before prescribing antibiotics, doctors frequently wait to observe how long your symptoms linger. Viruses are the common cause of sinus infections. Antibiotics cannot treat viral illnesses. Antibiotic resistance or needless adverse effects might result from overusing antibiotics or using them to treat viral illnesses. Future infections could be more difficult to treat as a result.


Can sinusitis be prevented?

There are several strategies to lower your risk of sinus infections depending on the underlying reason, such as:

  • Following your doctor’s instructions and rinsing your nose with saline (salt water).
  • Taking precautions against allergies. This covers over-the-counter drugs, allergy injections, and avoiding common allergy triggers (such as smoking, dust, or pollen).
  • Using steroid nasal sprays as advised by your physician.
  • Establishing healthy handwashing practices and other preventative measures against infectious illness infections.
  • Not smoking. If you smoke, there are strategies to assist you in stopping.

When I get sinusitis, what should I plan on?

Usually, sinusitis clears up in a week or ten. Generally, over-the-counter medications and at-home therapies can be used to treat it. You may need to treat underlying reasons if you have severe sinusitis or if it recurs often.

When should a sinus infection require evaluation by a physician?

Sinus problems are often manageable on your own. Talk to a healthcare professional, nevertheless, if your symptoms persist or if you frequently develop infections. They can assist you in determining what to do next.
