Acute sinusitis symptoms (nasal congestion, drainage, facial pain/pressure and decreased sense of smell) last less than four weeks. It's usually caused by viruses like the common cold. Subacute sinusitis symptoms last four to 12 weeks.
Untreated sinusitis allows bacteria and other harmful pathogens to enter the bloodstream and travel all throughout the body, leading to the following potentially life-threatening conditions. Meningitis develops when infection targets the brain or spinal fluid. It requires immediate medical attention.
Schedule an appointment with your doctor if:
See a doctor immediately if you have the following signs or symptoms, which could indicate a serious infection: Fever. Swelling or redness around your eyes. Severe headache.
Acute sinus infection lasts three to eight weeks. A sinus infection lasting longer than eight weeks is considered chronic. The sinuses are air-filled cavities.
You doctor may recommend antibiotics if: You have symptoms of a bacterial infection and you have not gotten better after 10 days, even with home treatment. Your symptoms are severe, or you have other problems, such as pus forming in your sinus cavities.
Other disease processes can mimic sinusitis including the common cold, allergies, migraine headache, chronic daily headache, myofascial pain, temporomandibular joint or jaw pain, rhinitis medicamentosa, and even sleep apnea. Therefore an accurate diagnosis requires a thorough history and physical examination.
Viral infections are spread the same way as bacterial infections. The difference is that the viral infection will start to improve after 5 to 7 days of the initial onset of the symptoms. There is no one definitive way for a doctor to determine if you have a bacterial or viral sinus infection based on symptoms alone.
If the condition lasts longer than ten days, or there is a worsening of symptoms after five to seven days, the sinusitis is more likely caused by bacteria than a virus.
Antibiotics only will be needed if the infection is severe, recurrent or persistent.
Symptoms can vary depending on the location of the brain abscess, but may include changed vision, fever, feeling sick, headache, nausea and seizures. “While rare, this is one of the most serious kinds of problems that can occur with a longstanding sinus infection,” said pediatric neurosurgeon Tanya Minasian, DO.
Imaging studies — a computed tomography (CT) or magnetic resonance imaging (MRI) test can show any complications in the structure of the nose that is causing your sinusitis. Nasal and sinus cultures — if your condition is worsening, a culture can determine the cause of the infection.
Left untreated, a sinus infection has the potential to spread to your meninges (the protective coverings around your brain and spinal cord), causing them to become inflamed — a condition called meningitis. Meningitis gives rise to the following signs and symptoms: Sudden, high-grade fever. Neck stiffness.
And if you can't open your eyes or you feel dizzy, these are major warning signs that your sinusitis is at a dangerous level. If not properly treated, you may incur infections in your ears, throat and even your brain (called meningitis.)
It's most often caused by the bacteria Streptococcus pneumonia. Or it may be caused by the bacteria Haemophilus influenzae.
Even if the infection becomes bacterial, 70% of the time the infection will go away within two weeks without antibiotics. In the event of severe headache, toothache, or face pain or for persisting fevers greater than 102 degrees you should be seen by your health care provider.
“It is often best-and many times, company policy-that employees stay out of work until they are fever-free for 24 hours, especially with the flu.” Nasal congestion with sinus or facial pain suggests a sinus infection. Sinus infections can be viral or bacterial. “Either way, it's best to stay home,” Wigmore says.
Does a sinus infection cause a sore throat? Yes, it certainly can. Sinus infections can often lead to complications with post-nasal drip — excess mucus draining down the back of your throat — which in turn can cause a sore throat or cough. Fortunately, there are several ways to relieve a sore throat due to sinusitis.
Are bacterial sinus infections contagious? No. Since they form inside the nose and not through an outside infection, bacterial sinus infections are not contagious. The underlying disease that caused a sinus infection—like a cold or flu—can be contagious, though.
Fatigue. As your body works hard to fight off the sinus infection, you'll feel more tired than usual. Fatigue can be also be caused by head pain, a lack of adequate sleep, and difficulty breathing due to sinusitis.
Cough. A cough may also be a symptom of a sinus infection. As mucus drips down into your throat, it can trigger a cough. Coughing up phlegm should be a sign that this condition is more than a common cold.
