Headache
A headache is pain, pressure, or discomfort in the head or face. MaxArc Medical Library helps explain headache patterns, possible warning signs, related checks, and safer questions to discuss with qualified licensed clinicians.
At a glance
Why it matters
Most headaches are not emergencies, but sudden severe headache or headache with neurologic symptoms, fever, stiff neck, injury, pregnancy warning signs, or confusion needs urgent review.
Care conversation
Tracking timing, triggers, severity, associated symptoms, medicines, and blood pressure can help a clinician understand the pattern.
Summary
Headache can feel like pressure, throbbing, sharp pain, tightness, or pain around the eyes, forehead, temples, scalp, neck, or face. The pattern matters: when it started, how severe it is, what comes with it, and whether it is new or different.
MaxArc Medical Library can help organize headache information in plain language, but a clinician must evaluate serious symptoms, repeated headaches, pregnancy-related symptoms, neurologic changes, injury, infection concerns, or sudden severe pain.

Checks that may add context
Clinicians may consider blood pressure, medicines, infection signs, pregnancy status, eye findings, neurologic exam, or imaging depending on symptoms and warning signs.
Tests and results should be interpreted with symptoms, history, exam findings, and qualified clinical review.

Seek urgent care if
Some headache symptoms need immediate attention because they may be associated with stroke, bleeding, infection, severe blood pressure problems, eye emergencies, injury, or pregnancy complications.
- Sudden severe headache that feels different from usual
- Headache with weakness, numbness, face drooping, confusion, or trouble speaking
- Headache with fainting, seizure, stiff neck, fever, or rash
- Headache after a head injury
- Headache with vision loss, severe eye pain, or new neurologic symptoms
- Pregnancy or recent childbirth with severe headache, swelling, or vision changes
Common possible patterns
Headaches can have many possible causes. Pattern, timing, triggers, associated symptoms, exam findings, and medical history help guide the next steps.
- Tension-type headache or stress-related pain
- Migraine pattern with light sensitivity, nausea, or recurring attacks
- Sinus or allergy-related pressure
- Dehydration, skipped meals, poor sleep, or alcohol use
- Eye strain or vision problems
- Medication overuse or withdrawal effects
- Blood pressure-related concern in some cases
Checks and tests that may be discussed
The right checks depend on symptoms and clinical context. Not every headache needs imaging or blood tests, but warning signs may change what a clinician recommends.
- Blood pressure measurement
- Medication and caffeine review
- Vision or eye exam when appropriate
- Neurologic exam when warning signs are present
- Blood tests when infection, anemia, pregnancy, or other causes are suspected
- CT scan or MRI when clinician evaluation suggests imaging is needed
What to track before care
Tracking details can make the care conversation clearer and help a qualified clinician understand patterns and possible triggers.
- When the headache started
- Location and type of pain
- Severity and how quickly it worsened
- Triggers such as food, sleep, stress, medicines, or injury
- Associated symptoms such as fever, vomiting, weakness, vision changes, or confusion
- Medicines used and whether they helped
Questions to ask a clinician
- What headache pattern does this sound like?
- Are there warning signs that need urgent care?
- Could my blood pressure, medicines, sleep, stress, or vision be contributing?
- Do I need tests, imaging, or an eye exam?
- What symptoms should make me seek urgent care immediately?
- How can I safely track headaches and triggers?
