A sinus infection, also known as sinusitis, develops when the sinuses located behind the forehead, behind the eyebrows, and on either side of the nose become inflamed or swollen due to a viral or bacterial infection. Other factors that can contribute to sinusitis include allergies, dental infections, nasal polyps, and a deviated septum. Sinus infections are categorized into two types: acute and chronic. Acute sinus infections are short-lived and typically result from allergies or the common cold. On the other hand, chronic sinus infections can persist for months and tend to recur frequently.
Pain
Sinus infections often start with the onset of pain, which is the most prominent symptom. The presence of several sinuses around the nose and eyes can lead to either a dull ache or a sharp, intense pain. Inflammation and swelling can create pressure, resulting in a pulsating and spreading sensation. This discomfort may be experienced in the forehead, jaw, and even the teeth.
A Persistent Nasal Discharge
When dealing with a sinus infection, one common symptom is a runny nose. This occurs when the sinuses become infected, leading to the production of excess mucus. The discharge from the nose is usually yellow or green in color. Additionally, this mucus may trickle down the back of the throat, causing a postnasal drip. This can result in an itchy throat and a persistent cough, particularly when lying down. If left untreated, the accumulated mucus can further exacerbate the condition and lead to additional complications.
