The Passport comes with a 4.5-inch square touch display with a 1440 x 1440 resolution and 453 PPI pixel density. Thanks to the integration of a touch-sensitive panel inside the hardware QWERTY keyboard below the display, your fingers almost never get in the way of reading or otherwise interacting with on-screen content.
Injury to the outer ear is by far the most common cause of tenderness and pain. The injury is usually obvious like with an ear piercing or blow to the ear. Trauma leads to inflammation which is characterized by pain, redness and swelling.
ETD and sinusitis definitely have a connection, mostly due to post-nasal drainage causing inflammatory swelling of the e-tubes. Due to nerve pathways, both TMJ disorders AND a problematic third molar (wisdom tooth) can cause pain to be referred to the ears.
