Headaches: Migraine, Tension, Cluster & Rebound

Roughly three-quarters of adults get a headache each year, and headaches are a leading cause of lost workdays and workplace frustration. They affect women more than men. Most are miserable but not dangerous — and most are treatable, often without the daily pain pills that, as you'll see below, can quietly make things worse.

First: the warning signs that need urgent care

Most headaches are not dangerous, but a few features warrant immediate medical attention. Physicians are specifically taught to treat these as red flags:

• The first or worst headache of your life.
• A headache from a fall or head trauma, especially if you lost consciousness.
• A constant, unrelenting headache, or one that has steadily worsened over weeks to months, or is worse in the morning.
• A headache causing speech problems, weakness, numbness, vision loss, or confusion.
• Headache with fever and stiff neck, or with exertion.
• New headaches in someone with a family history of brain aneurysms or polycystic kidney disease.

If any of these apply, this page is not your answer — seek medical care promptly, and call 911 for sudden severe "thunderclap" headache or headache with stroke-like symptoms.

What causes headaches?

This remains one of medicine's harder questions, and different headaches have different mechanisms. For migraine and tension headache, current understanding centers on a kind of "pacemaker" in the brainstem that influences the trigeminal nerve, the main sensory nerve of the head. Other headaches arise from muscle tension, pressure changes, sinus or dental disease, inflammation of blood vessels, blood pressure, or nerve problems. The good news is that treatment doesn't require solving the mystery completely — identifying which headache you have points directly to what helps.

The common headache types

Migraine. Typically one-sided, often throbbing, lasting anywhere from 4 to 72 hours, and more common in women. Some migraines come with an aura — visual changes lasting about 20–25 minutes beforehand — and some don't. Triggers range widely: certain foods, stress (or the release from stress, the classic weekend migraine), bright light, hormonal shifts. A frequently overlooked variant is the menstrual migraine, which starts about three days before the period. Nausea, light and sound sensitivity, and wanting to lie down in the dark are common. A useful rule: not all severe headaches are migraines, but most migraines are severe.

Tension headache. The most common type — usually both sides or the whole head, described as a tight band or dull ache that builds through the day. It affects women about four times as often as men, and clusters in the early morning and late afternoon (the classic "3:30 headache" of a stressful workday). Muscles around the head are often tender.

Cluster headache. Severe, one-sided pain around the eye and forehead with nasal stuffiness and tearing or redness of that eye, striking daily in bouts that last weeks to months. Uncommon and strongly male-predominant, usually beginning between ages 18 and 40. Attacks are short (30 minutes to a couple of hours) but can recur several times a day during a cluster period.

Occipital neuralgia. A dull ache at the back of the head, sometimes with scalp hypersensitivity, that can radiate to the top of the head or forehead. It often follows a whiplash-type injury.

Others include sinus, cervical (neck-origin), exertional, and facial-nerve headaches — several of which we cover on the facial pain page.

The rebound trap — read this if you take daily pain pills

Here is the single most important thing on this page for chronic headache sufferers: many headaches are actually caused by the headache medication itself. The cycle is insidious — you get a headache, take a pain reliever, it wears off, another headache comes, you take more. Over time the headaches grow more frequent and you're medicating constantly, because now your body reacts to the absence of the medicine with a headache. This is called rebound (medication-overuse) headache, and it applies to ordinary over-the-counter pills, not just prescriptions.

Part of why this happens ties to your body's own chemistry: taking pain medications daily may deplete your natural pain-killing system (the endorphins described on our natural painkillers page), leaving you dependent on the pills to feel normal — much like a coffee drinker's withdrawal headache. When rebound has set in, the only way out is carefully supervised withdrawal from the overused medication. This is exactly the kind of thing a specialist manages, and it's often the hidden key to headaches that "nothing helps."

How chronic headaches are treated

At Newport Pain Management, the visit starts with time — going over the history around when your headaches began, reviewing prior treatments and tests (bring your records and medication list), and a thorough exam. Once we identify the headache type, treatment falls into three families:

Preventive medications are taken regularly to keep headaches from starting, and modern options have expanded well beyond the older mainstays. Established preventives include beta-blockers, certain calcium-channel blockers, antidepressants such as amitriptyline, and anti-seizure medications such as topiramate and valproate. For migraine specifically, newer targeted preventives — the CGRP-blocking medications and Botox for chronic migraine — have meaningfully improved options for people who didn't respond to the older drugs.

Acute/abortive treatments stop a headache in progress. The triptans (such as sumatriptan) were the major advance here and remain first-line for many migraines; anti-nausea medications, certain anti-inflammatories, and — newer — the "gepant" and ditan classes give additional options for those who can't use or don't respond to triptans.

Pain and supportive care, including the non-drug tools that treat the whole picture: biofeedback, relaxation training, counseling for the stress that drives so many tension headaches, trigger management, and treatment of the sleep loss and mood effects chronic headaches cause.

Headaches are a serious matter, and needless suffering is common when the real cause — sometimes the medication itself — goes unaddressed. To find the answer to yours, call Newport Pain Management at (949) 759-8400.
