<s>[INST] My husband is having a sharp pain behind his right ear radiation down his neck. It only last a few seconds than goes away. He has had his blood pressure checked recently and everything checks out. He is very healthy otherwise. Exercises and eats right. Watches his weight. He is 58. [/INST] Hi, Thanks for writing in. Sharp shooting pain in the head and neck region lasting for few seconds is a common symptom on neuralgia of nerves supplying the region. There are nerves having branches that innervate the skin in the head and neck region including the back of the ear. Once such nerve is the trigeminal nerve. It arises from the brain stem and then goes to a relay center called ganglion. From there the nerves branch out to supply different areas. It is possible that a branch of the nerve supplying the area behind the ear and the neck are irritated at some place and causing the sharp pain. Please have him seen by a neurologist and his condition confirmed. Treatment is by medication in most patients. Please do not worry. </s>
