What are the main types of headaches?
There are two categories of headaches, primary headaches, where the headache problem is the disorder, and secondary headaches, where the headache is a symptom of an underlying condition like a stroke, a brain tumor or an infection. If we look at the primary headaches, there are four major kinds, migraine, tension-type headache, cluster headache and then the fourth group is a miscellaneous group of other, usually uncommon headache types.
How can the type of pain you have help doctors make a diagnosis?
One issue is the quality of the pain. Is it throbbing? Is it a steady ache? Another feature is the location of the pain. Is it in the eye? On one side of the head? On both sides of the head? Another feature of the pain is the frequency and duration. Do attacks last 10 minutes? Do they last 10 days? Do they occur every day? Do they occur only occasionally?
What is a cluster headache?
Cluster headache derives its name from the fact that the attacks tend to occur in clusters. So a person with cluster will have a long period where they don't have any headaches at all, and then they'll have what what's called cluster phase; where they will begin having attacks on a daily or near-daily basis for weeks or months. The cluster attacks tend to be short, they last 15 to 90 minutes.
