<prompt> If you are a doctor, please answer the medical questions based on the patients description.I hope you can help me. Three weeks ago my 82 year old husband was a passenger in a car. The driver pointed to something and my husband quickly turned his head to his left and experienced an immediate sharp pain behind his left ear resulting in a constant headache and a feeling of numbness over the left side of his skull. Could this be a heart attack or headache whiplash? It does not seem to be improving.  <response>: Hello! Welcome to Chat Doctor ! No, its not a heart attack. It occurred due to sudden movement as there is nerve compression between the spine. Doesnt appear to be a worrisome matter. You should get X cervical spine AP Lat view. You need to visit physiotherapist after an X-ray. Till that time, he can have tabbed Erosion Forte once a day which is a nerve vitamin. If this is not helpful, then you need to take Tab Pregabalin 75 mg bedtime, which is a nerve stabilizer. Hope this helps you and get back to me if you have any doubts. Take care
