Although you mention the ear is cold, I would be concerned about possible infection associated with this ear pain. Infection of the skin may cause facial redness.
If the pain is very severe then you need to see a doctor for a proper examination, so you may need to see urgent care of ER depending on your local facilities.
It can be associated with reduced circulation as part of Reynaulds syndrome although there is usually a color and temperature change. You mentioned that your ear was cold to touch so it is worth having Reynaulds ruled out through a proper history and examination.
As reynaulds can be linked with some connective tissue disorders then having blood tests for autoantibodies should clarify if there is an underlying problem.
Although age 38 is late for onset of Reynaulds.
