Acute Sinusitis Acute sinusitis is a common problem and is often associated with a viral or bacterial upper respiratory infection that spreads to the sinuses. The Effects of Acute Sinusitis Sinuses are lined by the mucosa, which keeps them moist and clean. When the mucosa is exposed to viruses, bacteria, pollen, smoke, or other irritants, the mucosal lining can swell up. This inflammation is accompanied by increased secretion of mucus and other fluids in an effort to rid the sinus of the offending particles. Tiny hair-like cilia on top of the mucosa, which help transport mucus toward the opening of the sinus, can become temporarily paralyzed. The sinus opening can become blocked, and the cavity fills with fluid, producing deep pain and pressure. Symptoms associated with acute sinusitis are headache, fever, and postnasal drip. 
Treatment Treatment of acute sinusitis is designed to relieve blockage of the sinus opening and restore cilial function. Different medications are available. Talk to your doctor about which are suitable for you.
