Headaches in the back of the head may be caused by a variety of ailments and injuries. Chronic headaches in the back of the head -- also known as occipital headaches -- are often variants of tension-type headaches or migraines. New-onset occipital headaches are a more urgent concern. Possible causes include blood vessel abnormalities, nerve disorders and serious traumatic injuries.
Other types of headaches: 1  Cluster headaches are sharp, very painful headaches that tend to occur several times a day for months, then go away for a similar period of time. 2  Sinus headaches cause pain in the front of your head and face. They are due to swelling in the sinus passages behind the cheeks, nose, and eyes. The pain tends to be worse when you bend forward and when you first wake up in the morning. Headaches may occur if you have a cold, the flu, a fever, or premenstrual syndrome.
