My 81-year-old otherwise healthy uncle began to have brief severe sharp pain in the left ear since 1 week ago. The pain only lasts shortly, rarely closes to 1 minute and shoots to the left side of the head before or over the left ear. He want to a local ER and the docotr said the ear and every thing were fine. He does not have other medical problems and still play basket ball daily. He has no new problems but this pain is very annoying. He told me that the pain may happen 2-3 times a minute, but he also has pain free intervals for 2-3 hours several times a day.
Pleas tell me what problem my uncle has and what is the treatment.
Thank you very much.
