Headaches are one of those nuisances in life that we all deal with but wish we didn’t have to, because having to handle all our daily tasks in the limited time we have is challenging enough, but doing it with a pounding headache makes it so much worse. We all get headaches, and having 1-2 headaches a month can be irritating but perfectly normal. Most headaches are usually harmless, but sometimes they can signal a serious underlying condition that requires immediate medical attention. Here’s how to tell the difference between a typical headache and one that could be cause for concern.
Most Headaches Are Benign
The vast majority of headaches are:
- Tension headaches (stress-related)
- Migraines
- Cluster headaches
- Headaches from dehydration, poor posture, or eye strain
These usually:
- Come on gradually
- Are not associated with other alarming symptoms
- Improve with rest, hydration, or over-the-counter painkillers
When a Headache May Be a Cause for Concern
Red Flag Symptoms — Seek Medical Attention If You Experience:
- Sudden and Severe Pain (“Thunderclap Headache”)
- Feels like the worst headache of your life, peaking in seconds to minutes
- Could indicate brain aneurysm, stroke, or brain bleed
- Headache with Neurological Symptoms
- Confusion, slurred speech, vision loss, weakness, numbness, dizziness, or seizures
- May suggest stroke, brain tumor, meningitis, or multiple sclerosis
- Headache After Head Injury
- Especially with nausea, vomiting, loss of consciousness, or memory issues
- Could be a concussion or subdural hematoma
- New Headache After Age 50
- Raises suspicion for temporal arteritis, brain tumors, or vascular issues
- Especially if associated with jaw pain, scalp tenderness, or vision changes
- Headache That Wakes You From Sleep
- Nighttime or early morning headaches can indicate increased intracranial pressure (brain tumor, hydrocephalus)
- Persistent or Worsening Headache Over Days/Weeks
- Could signal a slow-growing mass or chronic infection
- Especially concerning if not relieved by standard treatments
- Fever, Stiff Neck, and Light Sensitivity
- Classic signs of meningitis
- Requires urgent evaluation and antibiotics
- New Headache in Someone with Cancer or HIV
- May point to metastases, brain infections, or opportunistic diseases
When to See a Doctor Urgently
If you experience any of the above, or a headache that feels “off” from your normal, don’t wait. Go to the ER or contact a healthcare provider immediately.
Most headaches are minor. But if you notice a sudden onset, neurological symptoms, or persistent changes, they could be warning signs of something more serious, like stroke, tumor, or infection. When it comes to your head, it is certainly better to be safe than sorry.
