Understanding Headache Causes: From Sinus Issues to Serious Conditions

There are many factors that can cause bad headaches. These factors range from something as simple as sinus pressure to more serious ailments such as a brain aneurysm.

Sinus Headaches

• Sinus headaches are caused by swelling of the nasal passages due to an infection such as a cold or allergies. Sinus headaches are characterized by pain when you move your head quickly, and pain in one particular area of your head.

Migraine Headaches

• Migraine headaches occur when blood vessels in the brain have swelled, causing pain, nausea, and light sensitivity. There is no one definite cause of a migraine headache, but they have been linked to many factors, including allergies, consumption of alcohol, and eating certain foods such as chocolate or cheese.

Tension Headaches

• Tension headaches are most often related to stress. They can be caused by lack of sleep, or working in one position for a long period of time. Tension headaches are usually felt as pain surrounding your head. You may also feel tightness around your shoulders or neck.

Serious Health Conditions

• Bad headaches can also be caused by more serious ailments, such as an aneurysm, a brain tumor, or encephalitis. If your headache consists of a quick, sharp, intense pain, or is accompanied by stiffness of the neck or fever, you should see a health care professional immediately.
