What causes light sensitivity sinusitis?

Light sensitivity in sinusitis, also known as photophobia, can occur due to inflammation and irritation of the sinus cavities, which can affect surrounding nerves and tissues. This inflammation can lead to headaches and discomfort, making bright lights particularly painful or irritating. Additionally, sinus pressure and congestion may contribute to sensitivity to light as part of a broader response to pain. Overall, the combination of sinus-related pain and neural responses can result in light sensitivity during sinusitis episodes.
