Sinusitis is also known as sinus infection that leads to inflammation of the sinuses in the head. Sinuses are air filled spaces that are behind the forehead, nose, cheeks and eyes. If there is blockage of the sinuses by excessive mucous (due to a cold or flu) bacteria and viruses can build up leading to congestion, fevers, pressure like feeling and pain.
Acute sinusitis usually follows after a viral infection involving the upper respiratory tract but allergies can also lead to sinusitis. Due to mucous blockage and inability for sinuses to drain, bacteria and viruses easily grow and invade the lining of the sinuses. This leads to symptoms of sinusitis.
Medical attention should be sought out if symptoms such as pressure, fever, pain, is worsening or persisting especially for more than a week. Sinusitis can be treated several ways some simple things that you can do at home include steam therapy using a vaporizer or inhaling seat from a shower in the bathroom. Drinking fluids and using anti-inflammatory and pain reducing medications such as ibuprofen can also help. However your doctor may recommend decongestants such as nasal sprays that work quicker. It is important to note that decongestants should not be used for more than 3 days since they become less effective thus when stopping can lead to worsening congestion. Antibiotics may also be needed and there are several that your doctor can prescribe for worsening or persisting symptoms.
Sinusitis can also be prevented by washing your hands especially when in contact with others who have a cold or flu, obtaining influenza vaccination, staying hydrated, and avoiding allergens in the environment.
