Acute Sinusitis

How do you get acute sinusitis?

After a cold or the flu

In most people, acute sinusitis develops after a cold or a flu-like illness. Colds and the flu are caused by germs called viruses that can spread to the sinuses. The infection usually remains viral before disappearing, causing a viral infection in the sinuses. In a small number of cases, germs called bacteria are added to an infection that started with a virus. This can cause a sinus bacterial infection that can make the infection worse and last longer.

Propagation of a dental infection

In some cases, the infection spreads to a breast of the cheekbone (maxilla) of an infected tooth.

Risk factors for Acute Sinusitis

In some people, one or more factors are present that can cause the sinuses to be more prone to infection. These include:

Nasal allergy (allergic rhinitis). The allergy can cause swelling of the tissues in the inner lining of the nose and block sinus drainage channels. This makes the sinuses more susceptible to infection. See separate brochures that analyze allergic rhinitis, called hay fever and persistent rhinitis, for more details.

  • Growths (nasal polyps)
  • Objects introduced into the nose (especially in children, such as peas or plastic beads).
  • Facial injury or surgery.
  • Certain congenital abnormalities in children. (‘Congenital’ means that they are present from birth).
  • Asthma.
  • Cystic fibrosis.
  • A poor immune system, for example, people with HIV, people with chemotherapy, etc.
  • Inflammatory disorders such as Wegener’s granulomatosis or sarcoidosis.
  • Pregnancy, which makes it more prone to nasal inflammation (rhinitis).
  • Rare tumors of the nose.
  • Anterior lesions in the nose or cheeks.
  • Medical procedures such as ventilation or insertion of a tube through the nose into the stomach (nasogastric tube).
  • Of smoking.

Acute Sinusitis Symptoms

Symptoms that commonly occur include:

  • Pain and tenderness over the infected breast. The pain often – palpitates and worsens when you lean your head forward.
  • Chewing can be painful.

Nasal symptoms

  • A blocked nose Usually both sides of the nose feel blocked. Your sense of smell can also last a while.
  • A runny nose. If the discharge is green / yellow, you are more likely to have a bacterial (bacterial) infection in your sinuses. The green / yellow color is due to infected mucus and pus. A runny nose can dry if the sinus drainage channels are blocked with a thick mucus. If this happens, the pain and tenderness over the infected breast may get worse.
  • A high temperature (fever). This can develop and, in general, it can feel bad.
  • Headache
  • Bad breath
  • Toothache
  • Cough
  • A feeling of pressure or fullness in the ears
  • Fatigue

  • Irritability
  • Ear discomfort

Diagnose Acute Sinusitis

Your doctor can usually diagnose acute sinusitis by listening to your typical symptoms. They can also check if you have temperature or if you have tenderness over your sinuses. They can examine your nose, since often the lining of the nose is swollen in acute sinusitis. Usually, no research is needed to diagnose acute sinusitis. Occasionally, blood tests, X-rays, or scan are recommended if the diagnosis is not clear.

Treatments for Acute Sinusitis

Do you need antibiotics?

Not usually. Most cases of acute sinusitis are due to infection with a germ called a virus. As with colds, the immune system usually eliminates the virus and symptoms usually disappear within a couple of weeks. Antibiotics do not kill viruses.

Also, even if the infection is caused by germs called bacteria, the immune system will usually eliminate it. So, for most people with acute sinusitis, antibiotics are not needed. Antibiotics can also cause side effects. Side effects may include diarrhea, feeling nauseous (nausea), vomiting, skin rashes and fungal infection (thrush). However, antibiotics are sometimes useful. Your doctor is not likely to prescribe an antibiotic for a mild episode of acute sinusitis. But antibiotic treatment may be prescribed in some cases, for example:

If your symptoms are severe or if you feel very bad.
If you have another disease, such as cystic fibrosis, heart problems or a weakened immune system.
If your symptoms do not resolve within seven days or get worse.
