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.
Although your head hurts, tension headaches usually don't keep you from your daily activities, and they don’t affect your vision, balance, or strength.
