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.
The most common types of headache are migraines and tension headaches. Other types of headaches include cluster and rebound headaches. Most people describe a tension headache as a constant, dull, achy feeling on both sides of the head, or like a band around the head. Some people who have tension headaches also have a tight feeling in their jaw or neck muscles.
