I had sharp pain on top my head ,when i move just right. then my neck feel like going spasm . what does this soumd like ?

Neck pain: Neck pain when turning to the right that radiates to the top of the head and is associated with muscle spasms could be a pinched nerve in the cervical spine. Sometimes complications from a root canal can mimic a pinched nerve in the neck. See your dentist to ensure there are no complications related to the recent procedure before seeking a spine specialist.
