Cough and Sinusitis

Sinusitis is a common condition, affecting approximately 30% of the population. It is more prevalent in adults but can also occur in infants and children.

Common symptoms:
Sinusitis is described as swelling or inflammation of the sinuses; the air-filled cavities located inside the bones of the skull on either side of the nose, behind and between the eyes and in the forehead. It is usually caused by an infection and is quite common after a cold or flu.

Some of the common symptoms of sinusitis include pain, swelling and tenderness around the cheeks, eyes and forehead; a blocked nose; reduced sense of smell; green or yellow mucus from the nose; a headache; high temperature, toothache and bad breath.

Cough symptoms:

Another common symptom of sinusitis is cough. Frequent sinus infections can cause post-nasal drip, where mucus drains down the back of the throat, tickling the throat and the nerves of the nasopharynx (the space above the soft palate at the back of the nose, which connects the nose to the mouth) to cause a chronic cough. Coughing from a sinus infection gets worse at night and in the morning, when the mucus drains down the back of the throat.

A chronic cough is defined as a cough that lasts more than 8 weeks. It is rated as one of the most common reasons for seeing a doctor. In fact, studies have shown that one-third of chronic cough patients have sinusitis. Coughing from a sinus infection will often manifest as a dry irritating cough A “productive” or wet cough, which can sometimes even be mistaken for bronchitis, can occur when the post nasal drip persists and the mucus pools in the lungs.

Ideally treatment for sinusitis following a correct diagnosis involves controlling the source of sinus infection, re-establishing proper nasal drainage, and relieving pain. Using a cough suppressant or nasal decongestant can alleviate symptoms of a dry cough. A mucolytic can be useful for a wet cough when mucus or phlegm is thick and sticky, as it thins the mucus, making it easier to cough it up. Home remedies can also include drinking plenty of fluids and using a humidifier.
