When To Worry About a Headache

Headaches are a common symptom of many different health conditions. The burden of severe headache and migraine is high in the United States, where it affects one in six Americans at least once during a three-month period, reports the journal Headache.

Headaches can be caused by a wide range of problems, some of which are more serious than others. Knowing when to worry about a headache can help you stay informed regarding when it’s time to see your doctor for help.

Here’s a guide on when to worry about a headache and how to contact Healthcare Associates of Texas when you’re ready to seek treatment.


When Is a Headache Serious?

Many headaches go away on their own within a few minutes or hours. Some headaches are caused by hunger or dehydration, which means eating a meal or drinking water can make them go away. Headaches caused by eye strain can be treated using massage or by taking a break from screen time.


A headache is serious when it doesn’t go away or is accompanied by other symptoms that indicate another health problem.

There are more than 100 types of headaches, reports Cedars-Sinai. However, there are some types of headaches you should worry about that require immediate medical attention. These headaches are related to stroke, heatstroke, concussion, and preeclampsia.



Most strokes are caused by a clogged artery in the brain that blocks blood flow. A severe headache that comes on suddenly may indicate you are having a stroke.

Call emergency medical services immediately if you are experiencing symptoms of a stroke. According to the CDC, stroke symptoms include:

  • Sudden, severe headache
  • Sudden numbness or weakness in the face or limbs, especially on one side of the body
  • Sudden confusion
  • Sudden vision problems
  • Sudden loss of balance and coordination
  • Sudden dizziness
  • Sudden confusion and difficulty with talking and understanding speechbook_now

  • Severe headache
  • Dry skin with no sweating
  • Nausea and vomiting
  • Sudden confusion
  • Slurred speech
  • Dizziness and fainting
  • Muscle cramps
  • Problems with balance and coordination

  • Nausea and vomiting
  • Blurred or double vision
  • Problems with balance and coordination
  • Delayed reaction time



Preeclampsia is a pregnancy complication associated with high blood pressure. This condition usually develops after week 20 of pregnancy and can cause frequent headaches during the third trimester. When not treated, it can damage major organs and lead to death in newborn babies and their mothers.

Symptoms of preeclampsia include:

  • Frequent, persistent headaches
  • Nausea and vomiting
  • Vision problems
  • Dizziness
  • Shortness of breath

When To Worry About a Migraine

A migraine is a type of severe headache. A migraine causes severe pulsing or throbbing pain that usually only occurs on one side of the head. Migraines are often accompanied by symptoms including nausea, vomiting, and sensitivity to light and sound.

Many people who suffer from migraine headaches usually take medications that prevent them from happening or that reduce symptoms.

You should worry about a migraine if it is accompanied by certain other symptoms. These symptoms include:

  • An abrupt, painful headache that feels like a “thunderclap”
  • Fever or stiff neck
  • A headache that occurs after a head injury
  • Vision problems
  • Seizures
  • Mental confusion
  • Numbness or weakness in any part of the body
  • Headache that gets worse when coughing or straining
  • New type of headache pain that suddenly starts after you turn 50 years old


What Are Treatment Plans for Serious Headaches?

If you are suffering from serious headaches, your doctor will work with you to find out what’s causing them. Then, your doctor will treat the underlying cause of your headaches to make them go away.

Some tests can determine what’s causing your serious headaches. These include CT scans, MRI, blood tests, and hearing and vision tests. Your doctor may also order other tests or refer you to a specialist depending on your results.

Serious headaches may be treated with medications that prevent them or that reduce the severity of their symptoms. Otherwise, treatment depends mainly on the root cause of your headache. For example, if your headaches are being caused by high blood pressure, your doctor may work with you to modify your diet or encourage you to start a fitness program.


When It’s Time To See a Doctor

See your doctor right away if you recently started experiencing headaches that are frequent or severe or accompanied by other symptoms. You should also see your doctor if your headaches don’t go away within a few hours or cannot be relieved with over-the-counter or home remedies.
