Headache warning signs and when to call the doctor

Headaches, unfortunately, are fairly common and can happen to anyone, at any time, in any place.^1,2

Thankfully, headaches are so common that for the most part they are nothing to worry about. In most cases, head pain, neck pain and the other symptoms of a headache only lasts for a matter of minutes or hours.³

But what if the pain doesn’t go away? And what if there are additional symptoms or sickness? More importantly, how can you tell when a headache is just a headache — and when to seek medical care?

Headache warning signs

It’s not always easy to know when to consult a doctor about a headache. But there are some definite warning signs that signal that a headache may be more serious. A sudden, severe headache or head pain that occurs with other signs of injury can be a symptom of a more serious medical condition.^3-5

If you experience any of the following symptoms with a headache, call a doctor or seek other immediate medical attention.^3-5

Stiff neck and fever

Some headaches, such as tension headache, can be accompanied by tightness in the neck.² But a sudden, severe headache along with a very stiff neck and a fever and/or sensitivity to light could be a sign of a serious infection that requires medical attention.^4,5

Numbness or weakness

Numbness or weakness with a headache, including slurred speech, difficulty speaking, or difficulty walking could be symptomatic of a more serious condition.⁵ Speak with your doctor about whether additional treatment is needed.

Altered vision

Double, blurred vision or partial loss of vision with a headache.^3,5

Confusion, convulsions, or loss of consciousness

When paired with a headache, confusion, or loss of consciousness are all warning signs of serious illness or injury.^4,5 These may occur with the onset of head pain or after experiencing a headache. Either way, you should seek immediate medical attention.

Head injury

Any time a head injury results in a headache, consult a doctor right away.^4,5 Head pain following a head trauma could be a sign of damage that requires treatment from a healthcare professional.
