Which condition is often associated with sinus pressure and headaches?

Sinusitis is often associated with sinus pressure and headaches due to the inflammation and swelling of the sinuses. This condition occurs when the nasal passages become blocked, limiting the drainage of mucus and leading to increased pressure in the sinus cavities. The buildup of pressure can cause pain and discomfort, particularly in the forehead, cheeks, and around the eyes, which are typical areas affected by sinus headaches.

In sinusitis, the inflamed sinus tissues can also lead to other symptoms such as nasal congestion, facial pain, and a reduced sense of smell. The combination of these symptoms directly correlates with the experience of pressure in the sinuses and the resultant headaches, making sinusitis a common cause for individuals experiencing these issues.

In contrast, nasal polyps, while potentially contributing to sinus blockage, do not directly cause sinus pressure or headaches as their primary manifestation. Rhinorrhea refers to nasal discharge, which may occur with various conditions but does not specifically correlate with headaches. Allergic rhinitis can lead to sinus congestion and discomfort, but it is more closely associated with sneezing and itching than with the pressure and headaches typical of sinusitis.
