Sinus infection and dizziness are commonly experienced together as sinus infections can lead to ear infections that cause dizziness. Also, some of the side effects of a sinus infection can make people feel dizzy or light-headed, although the balance system located in the ear is not affected. Prompt treatment of these infections can help reduce the risk of developing dizziness. It's important for people to watch for early warning signs of sinus infections, including a thick nasal discharge and a feeling of pressure, pain, or heaviness in the face.
The sinuses are a series of cavities in the skull. In healthy individuals, they contain air pockets, but in those with a sinus infection, they fill with mucus and other fluids that build up as the body responds to the infection. Many people with sinus infections develop fatigue and headaches, two problems that can make them feel unsteady on their feet, especially when severe.
It is also possible for a sinus infection to cause an ear infection and accompanying dizziness by blocking the Eustachian tube. This structure normally drains fluid from the inner ear. When it's blocked, fluid builds up, which can disrupt the vestibular system, the system the body uses to maintain balance. Untreated sinusitis can also lead to ear infection.
If people are experiencing a sinus infection and dizziness and are not already on treatment, they should see a medical professional. He or she can evaluate the patient and prescribe medications to kill the organisms causing the infection. Combined with rest and plenty of fluids, this should help the patient fight the infection and return to normal. People who experience recurrent or chronic sinus infections may want to explore preventive care, including allergy treatment to reduce swelling in the sinuses and surgery to widen drainage openings and prevent fluid buildup.
Knowing the possible symptoms of a sinus infection is important for people who work in jobs where dizziness can become a safety issue. These individuals may wish to request reassignment while they have active infections to reduce the risks associated with their work. People should also avoid strenuous exercise as they can fall and injure themselves.
