This happens when mucus drips down from the nose to the throat, causing congestion in the throat. The sinus inflammation can cause pain, postnasal drip and difficulty breathing at night. Many people with sinus infections feel fatigue and it can cause sleep disturbances. The mucus may be thick and colored yellow or green. Sinus infections can cause fluids to build up in the nasal cavity, leading to a runny nose. You may also have pain in the jaw, under the eyes or on the bridge of the nose, as the pressure pushes down from the sinuses. Swelling in the maxillary sinuses causes pain in the teeth and the face because they are located above the top teeth around the cheeks and nose. Sinusitis leads to increased pressure in the inner ear and nasal cavity, which can cause pain and discomfort in your teeth and around your face. It puts pressure on your eardrum, affecting your balance and causing dizziness and nausea. Sinus infections can change the pressure of the inner ear from fluid buildup. Some sinus headaches result from problems other than an infection, so you may not have sinusitis if your only symptom is a headache. Inflammation from a sinus infection increases the pressure around the sinuses, which can lead to headaches. Infections prevent the sinuses from draining, leading to a buildup of fluids and pressure, which causes nasal congestion. ![]() Chronic infections last more than 12 weeks, while recurrent infections flare up several times a year. Acute infections last for less than four weeks and subacute infections last four to 12 weeks. There are a number of symptoms that accompany sinus infections and there are four categories, depending on how long the symptoms last. Nasal allergy infections are also not contagious because they are a result of the body’s own immune response to allergens. A viral sinus infection is contagious, while a sinus infection caused by bacteria or nasal blockage from a foreign object is not. One of the main differences is that a cold only lasts about five to ten days, whereas sinus infections can last for weeks or months.Ĭolds are contagious and some sinus infections can be as well. But sometimes a cold can turn into a sinus infection. Although the symptoms are similar to a cold, a sinus infection is different because it can be bacterial and not only viral. Many people cannot tell whether they have a cold or a sinus infection. It can disrupt the way the sinuses drain and cause infections. A deviated septum is when the nasal septum is severely off-center. People with a deviated septum are also more likely to develop sinus infections. They can keep fluids trapped in the nasal cavity, causing bacteria buildup. As the body’s immune system responds to dust, pollen or dander, it leads to inflammation.Ī broken nose or a physical obstruction in the sinuses can also lead to a sinus infection. Allergies are also a common cause of sinus infections. When these substances spread to the sinuses, it leads to inflammation and blocks the sinuses, keeping them from draining properly and causing pressure to build up. Causes of Sinus InfectionsĪ sinus infection can be viral, bacterial or fungal. Like a cold, infections can also be viral, which are harder to treat than bacterial sinus infections because they do not respond to antibiotics. When the sinuses do not drain, bacteria can build up and cause infection. But unlike a cold or flu, they can be bacterial. You may have nasal congestion, headaches, dizziness and fatigue. ![]() Sinus infections share many symptoms with the common cold and the flu. But when they are blocked, fluid can build up and cause infection. When the sinuses drain, the nose is clean. The sinuses are cavities that make mucus to drain out of the nose, and sinus inflammation can cause infection. A sinus infection, also known as sinusitis, is a common medical condition that affects millions of people every year.
