This is Dr. David
the pain behind the right ear could be from a pinched nerve in your neck, high up in your neck.
long procedures on the eye can put strain on your neck and pressure on nerves there.
I'm glad the tylenol helps some
you should limit your tylenol daily dose to less than 3000-4000mg a day, less if your liver is not well.
I would ask your doctor if an MRI scan of your neck cervical spine with contrast could see pinched nerves in your neck.
you might benefit from accupuncture in your neck to decrease pain
physical therapy or massage therapy could help as well
let me know if you have other questions.
