Tension headaches are dull pain, tightness, or pressure around your forehead or the back of your head and neck. Some people say it feels like a clamp squeezing the skull. Often called stress headaches, they’re the most common type for adults.

When you get them less than 15 days per month, they’re called episodic tension headaches. If they happen more often, they’re called chronic.
These headaches can last from 30 minutes to a few days. The episodic kind usually start gradually, often in the middle of the day.
Chronic ones come and go over a longer period of time. The pain may get stronger or ease up throughout the day, but it’s almost always there.
Who Gets Them?
Up to 80% of adults in the U.S. get them from time to time. About 3% have chronic daily tension headaches. Women are twice as likely to get them as men.
Most people with episodic tension headaches have them no more than once or twice a month, but they can happen more often.
Many people with the chronic type have usually had them for more than 60-90 days.
What Causes Tension Headaches?
There's no single cause for them. Most of the time, they’re triggered by stress, whether from work, school, family, friends, or other relationships.
Episodic ones are usually set off by a single stressful situation or a build-up of stress. Daily strain can lead to the chronic kind.
This type of headache doesn’t run in families. Some people get them because of tightened muscles in the back of the neck and scalp. This muscle tension can come from:
- Not enough rest
- Bad posture
- Emotional or mental stress, including depression
- Low iron levels
For others, tightened muscles aren’t part of tension headaches, and there’s no clear cause.
What Are the Symptoms?
A few common ones are:
- Mild to moderate pain or pressure in the front, top, or sides of the head
- Headache that starts later in the day
- Trouble sleeping
- Feeling very tired
- Trouble focusing
- Mild sensitivity to light or noise
- Muscle aches
Unlike migraine headaches, you won’t have other nerve symptoms, such as muscle weakness or blurred vision. And they don’t usually cause severe sensitivity to light or noise, stomach pain, nausea, and vomiting.
How Are They Treated?
It’s best to treat tension headaches when they first begin and the symptoms are still mild. The goal is to prevent more of them from happening and to relieve any pain you're already in. For prevention, you can:
- Take medications
- Avoid the causes or triggers
- Manage your stress or learn relaxation techniques
- Practice biofeedback
- Try home remedies, like a hot bath, ice packs, or better posture
Over-the-counter (OTC) painkillers are often the first treatments doctors recommend for tension headaches. People with the chronic kind can use some of these drugs to prevent headaches.
If OTC pain relievers don't help, your doctor may recommend a prescription-strength med or a muscle relaxant.
Some drugs can keep you from getting a tension headache, like antidepressants, blood pressure meds, and anti-seizure drugs. You take them every day even if you aren’t in pain, so that you end up using less medication over time.
Keep in mind that medications don't cure headaches and that, over time, pain-relievers and other drugs may not help as much as they did at first. Plus, all medicines have side effects. If you take one regularly, including products you buy over-the-counter, discuss the risks and benefits with your doctor. You'll still need to find out and deal with the things that are causing your headaches, too.
