I had a similar problem after a bad car accident and I had all the medical tests done and nothing helped. I went to a chiropractor and he said I had some abnormal stuff in my neck which could be bothering the nerves. I got treated and haven't had the problem since. Maybe this is what is wrong with you it is worth a shot and it was cheaper than the first test the hospital did alone, I wish I would have seen him first and saved all that money. Good luck.

Without the ability to take a detailed history from you and do a physical examination, I can not tell you what the cause of your ear pain is. However, I will describe to you some of the neurologic and non-neurologic causes of episodes of ear pain.
Most commonly, ear pain is not neurologic. It is most often otologic: coming from the ear. This could be due to ear infection of the inner ear (otitis media) or outer ear (otitis externa), trauma, reflux.
Ear pain can be referred: coming from other areas besides the ear. The ear canal is very well innervated: it receives nerve endings from a variety of nerves that also innervate (supply) other areas. A neuralgia of the nerves that innervate the ear can cause pain referred to the ear. An example of a neuralgia is trigeminal neuralgia, I'm not sure if you have heard of this, it is an irritation of one of the nerves that supply sensation to the face and it can cause sharp shooting face pains, in addition to ear pains. The neuralgias can be treated with medication or injections.
Ear pain can be referred from problems in the throat, or the temporo-mandibular joint (TMJ), which often leads to problems when people grind their teeth at night. Ear pain can also be referred pain from a dental problem, such as a tooth abscess.
In the presence of associated symptoms such as hoarseness, weight loss, difficulty swallowing, pain during swallowing, recurrent nose bleeds, or a neck mass, ear pain may be indicative of a tumor in the head or neck area.
When ear pain is triggered by neck movement this may imply that the nerves that innervate the ear that arise from the cervical spine (particularly the C2 nerve) may be irritated. One way to have that assessed is by obtaining an MRI of the cervical spine (the neck area).
As you can see, ear pain can be otologic or neurologic. Evaluation by an Ear/nose/throat (ENT) specialist and a neurologist may help you further understand the cause of your symptoms and find relief from them.
