Sinusitis is a common condition characterized by the inflammation of the nasal sinuses. It’s important to distinguish between sinusitis and other conditions like colds or COVID-19, as they can have overlapping symptoms. The main symptoms of sinusitis include loss of smell or taste, cough, bad breath, fever, toothache, and fullness in the ears. These symptoms arise due to the blockage of sinuses, often caused by swelling in the nasal passages from colds or allergies.

Initial symptoms are similar to a cold, such as fatigue, cough, and impaired sense of smell. To soothe these symptoms, it’s recommended to use nasal rinses, decongestants, and pain relievers. Painful pressure is a key symptom of a sinus infection, and its location can indicate which sinus is affected. For instance, pain in the forehead suggests frontal sinusitis, while pain over the cheek or upper jaw indicates maxillary sinusitis.

Sinusitis symptoms can be especially common in children and can stem from various causes. The duration of symptoms helps classify sinusitis: acute sinusitis lasts less than 30 days. Bacterial sinus infections may present with headache, fever, and discolored nasal discharge. If you’re experiencing these symptoms or if your condition persists beyond the common cold’s duration, consulting with a healthcare provider is advisable.
