This is Dr. David
pain in the ear can be from a pinched nerve high up in the neck
or could be due to trigeminal neuralgia of the trigeminal nerve in the brain.
after radiation therapy, the brain mets should be smaller and shouldn't be causing pain.
but radiation can cause dry skin around the ear and in the ear canal
radiation can also cause fluid in the inner ear and cause muffled hearing
if she has dryness of the skin around the ear and ear canal, she might benefit from some moisturizing oils around the ear of the skin.
