Sinusitis is an inflammation, or swelling, of the tissue lining the sinuses. Normally, sinuses are filled with air, but when sinuses become blocked and filled with fluid, germs (bacteria, viruses, and fungi) can grow and cause an infection.954 cohort participants had developed lung cancer. Compared with subjects without such history, subjects who reported a history of physician-diagnosed rhinitis or sinusitis at baseline, whether allergic or nonallergic, had a statistically significant 59% increase in risk of lung cancer (hazard ratio [HR] = 1.59; confidence interval [CI] = 1.06–2.37).
Meeting a medical practitioner
Acute sinusitis if you have a simple sinus infection, your health care provider may recommend treatment with decongestants like Sudafed and steam inhalations alone. Use of non-prescription decongestant nasal drops or sprays may also be effective in controlling symptoms. However, these medicines should not be used beyond their recommended use, usually four to five days, or they may actually increase congestion. If antibiotics are given, they are usually given for 10 to 14 days. With treatment, the symptoms usually disappear and antibiotics are no longer required.
Mucus is developed by the body to moisten the sinus walls. In the sinus walls, the mucus is moved across tissue linings toward the opening of each sinus by millions of cilia (a hair-like extension of a cell). Irritation and swelling from an allergy can narrow the opening of the sinus and block mucus movement. If antibiotics and other medicines are not effective in opening the sinus, surgery may be necessary. Also, if there is a structural abnormality of the sinus such as nasal polyps, which can obstruct sinus drainage, surgery may be needed.
