Acute Sinus Infection Symptoms

Sinus Symptoms vary somewhat, depending on the type of sinus and whether the infections are acute or chronic (see Sinus Infection).

The most common type of acute sinus develops in the largest sinus cavities in the skull, and those are situated in the cheekbones.

The reason?

Maxillary Sinus

Most of the Maxillary sinus cavity is located below the bridge of the nose (see illustration) and this is where mucus tends to settle.

After accumulating in this lower section, the waste must then travel to the nostril in order to drain.

During waking hours when the body is erect, the pull of gravity makes it difficult for mucus to drain naturally.

This causes stagnant pockets of mucus to collect... and these are the natural breeding ground for sinusitis inducing bacteria.


Sinus infection symptoms are described in the following video:

Maxillary Sinusitis (in the cheekbones)

  • Red or swollen cheeks that feel tender when touched.
  • Painful upper jaw and aching teeth.
  • Sinus headache focused across one or both cheeks and below the eyes.
  • Prolific nasal discharge with occasional plugs of thick yellow or green mucus.
  • Post-nasal drip (down the back of the throat), sometimes accompanied by a sore throat.
  • Bad breath.
  • Pain and pressure is worse when upright or bending forward and better when lying down.
  • Low-grade fever is common.


Frontal Sinusitis (in the forehead)

  • Severe sinus headache in the brow area on one or both sides.
  • Thick yellow or green tinged nasal discharge.
  • Post-nasal drip, occasional sore throat.
  • Bad breath.
  • Pain eases when upright and intensifies when lying down.
  • Low-grade fever is common.

Paranasal sinuses

Sphenoid Sinusitis (behind the eyes)

  • A cap of dull, deep pain that seems to encircle the head, starting at the back and continuing round to just behind the eyes. Pain in the top of the skull.
  • Double vision, tunnel vision, bright flashes, eyesight goes in and out of focus and other disturbances may be experienced.

    On rare occasions these sinus infection symptoms may indicate that sinus pressure extends to the membranes lining the brain. This is a dangerous condition requiring immediate medical attention.

  • Thick nasal discharge with plugs of yellow or green mucus.
  • Post-nasal drip, occasional sore throat.
  • Bad breath.
  • Pain intensifies when lying on the back or bending forward.
  • Low-grade fever is common.


Ethmoid Sinusitis(above the bridge of the nose between the eyes)

  • Pressurized pain in the corners of the eyes close to the tear ducts, or down one or both sides of the nose.
  • Pressure headache in one or both temples.
  • Sinus congestion with occasional prolific nasal discharge containing yellow or green plugs of mucus.
  • Post-nasal drip, sore throat.
  • Bad breath.
  • Pressurized pain intensifies when coughing, sneezing or lying on the back, and eases when standing or sitting with the head upright.
  • Loss of smell can occur
  • Low-grade fever is common.


Chronic Sinus Infection Symptoms

Maxillary Sinusitis

  • Dull pressurized pain below the eye.
  • Pain increases with allergic reactions, colds or ‘flu.
  • Dull, aching toothache in the upper jaw, (known as "sinus toothache").
  • Discomfort builds up during the day and culminates in nighttime coughing.

Frontal Sinusitis

  • Persistent low-grade sinus pressure headache in the brow area.

  • This is a sign of abnormal anatomic variations inside the nose, such as a deviated septum that restricts the nasal passages.

Ethmoid Sinusitis

  • Congestion.
  • Chronic nasal discharge.
  • Persistent background pain across the bridge of the nose.
  • Pain on bridge of nose intensifies when wearing eyeglasses.
  • Post-nasal drip.
  • Chronic sore throat
  • Bad breath
  • Pain worse in the late morning

Sphenoid Sinusitis

  • Continuous low-grade headache in most patients


Do not Underestimate the Dangers of Sinusitis

Due to the proximity of the brain to the sinus cavities, one of the deadliest complications of sinusitis is the spread of infection through the bones or blood vessels to the brain.

Abscesses, meningitis, and other life-threatening conditions may result.

In extreme cases the victim may experience severe headaches, mild to moderate personality changes, altered consciousness, visual problems, and if left untreated, seizures, coma, and eventually death.

On rare occasions fungal growth as opposed to anaerobic bacteria, may be responsible.

In this instance, the sinus infection symptoms could be relatively mild at first, but then intensify within a few days or even hours.

This could be a sign of Acute Invasive Fungal Sinusitis spreading to the meninges surrounding the brain.

Dangerous fungal growths in the sinus tissue, eye socket, facial bone and brain could develop as a result.

Sinus infection symptoms related to the eye socket can start with swollen or droopy eyelids and then develop into:

  • Fixed dilated pupils.
  • Inability to move the eyes from side-to-side.
  • Vision problems.
A person experiencing any of the above would become totally incapacitated and dangerously ill.

In the case of acute invasive fungal sinusitis, immediate hospitalization followed by emergency surgical procedures and aggressive anti-fungal treatment is mandatory... This condition could lead to blindness, coma and death.
