Your eye must be protected, as you already know. During the day, use artificial tears and every time you think of it, which needs to be often, use your hand to make your eyelid blink. At night use a heavier ointment. At night I used a pair of cheap plastic gogles to hold in place a scrap of polartec material. As for the ears, stay out of the wind.
Any breeze seems to hurt the eye and ear.
Use whatever pain releaver you would use for minor pain. Try adjusting your diet. Avoid cola, chocolate, nuts, peanut butter. Exercise every muscle in you face, even thought it may seem like there is no movement. Do this often.
