Sinusitis (or rhinosinusitis) is defined as an inflammation of the mucous membrane that lines the paranasal sinuses and is classified chronologically into several categories: [63] Acute sinusitis – A new infection that may last up to four weeks and can be subdivided symptomatically into severe and nonsevere. Some use definitions up to 12 weeks.
Acute sinusitis lasts a maximum of 12 weeks. The clinical symptoms of acute rhinosinusitis are purulent nasal secretion, nasal obstruction and/or tension headache or feeling of fullness in the facial area. Acute rhinosinusitis can be caused by a viral or bacterial infection – a distinction is not possible during the first days.
Air caught in nasal cavities – namely the sinus cavities, cannot be released and the resulting pressure may cause a headache or facial pain. If the sinus passage remains blocked, there is a chance that sinusitis may result. [6] If the mucus backs up through the Eustachian tube, it may result in ear pain or an ear infection.
Rhinosinusitis is inflammation or infection of the sinus cavities. Acute rhinosinusitis has symptoms lasting less than four weeks, while chronic rhinosinusitis lasts greater than 12 weeks. [ 8 ] This persistent irritation can lead to increased mucus production as a result of pro-inflammatory pathways, producing symptoms of PND.
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea.

Research on safety and efficacy of existing treatments is limited to a handful of published studies with a small number of participants and self ...
Post-acute infection syndromes (PAISs) or post-infectious syndromes are medical conditions characterized by symptoms attributed to a prior infection. While it is commonly assumed that people either recover or die from infections, long-term symptoms—or sequelae —are a possible outcome as well. [ 1 ]
In most cases of sinus barotrauma, localized pain to the frontal area is the predominant symptom. This is due to pain originating from the frontal sinus, it being above the brow bones. Less common is pain referred to the temporal, occipital, or retrobulbar region. Epistaxis or serosanguineous secretion from the nose may occur.
