profession. It is known by various different names: dental orthopedics, dentofacial orthopedics, cranio-mandibular orthopedics, and jaw orthopedics.
Sinus infections often follow a cold and cause pain and pressure in your head and face. Sinusitis can be either acute (sudden) or chronic (long-term). With chronic sinusitis, the infection or inflammation does not completely go away for 12 weeks or more.
If a viral infection is the cause it's a matter of time until the sinusitis clears on its own. When a bacterial infection is the cause you may need to take an antibiotic for at least 3 weeks. This inflammation can block sinus drainage, cause increased mucus production, and bleeding that may mix with the mucus. As the sinus infection clears, this mucus may drain from the nose and sinuses down the back of the throat causing a postnasal drip that can be irritating to the throat.
