It can be hard to know which
type of headache you have, because different types can have the same symptoms. But the treatments may be different, so it's important to find out which type you have.

serious health problems (such as
brain tumors or
aneurysms). But most headaches aren't caused
by anything serious, so you probably won't need to have tests.
