Headache and Migraine: When Urgent Care Can Help

Headaches range from mild tension pain to debilitating migraines — and sometimes they signal something more serious. Knowing when urgent care for headaches is the right move can save you time and get you relief faster. CityHealth San Leandro treats headaches and migraines same-day, including injectable pain relief.

Types of Headaches: A Quick Primer

Not all headaches are the same, and the type determines treatment:

Tension Headache

The most common type. Described as a tight band or pressure around the head, usually bilateral (both sides), mild to moderate intensity. Often triggered by stress, poor posture, eye strain, or dehydration. Typically responds to OTC pain relievers.

Migraine

Moderate to severe, usually one-sided, pulsating or throbbing. Often comes with nausea, vomiting, and extreme sensitivity to light (photophobia) and sound (phonophobia). Can last 4–72 hours. About one-third of migraine sufferers experience aura — visual disturbances, tingling, or speech difficulty before the headache starts. Significantly more debilitating than tension headaches and often doesn’t respond to OTC medications alone.

Cluster Headache

Intense, drilling pain around one eye or temple. Occurs in clusters — multiple times per day for weeks, then disappears for months. Extremely painful (often described as the most severe pain humans experience). Rare but needs prescription treatment.

Secondary Headaches

Caused by another condition: high blood pressure, sinus infection, medication overuse (rebound headaches), post-concussion, meningitis, or more serious causes. These need investigation.

When to Go to Urgent Care for a Headache

Urgent care at CityHealth is the right place when your headache is severe enough to affect your day but doesn’t have alarming features suggesting an emergency. Come in if:

• Your headache is the worst you’ve had — but you’ve had severe headaches before and this feels similar to past migraines
• OTC pain relievers (ibuprofen, acetaminophen) aren’t working and you need prescription treatment
• Migraine is causing significant nausea/vomiting — we can provide IV or IM anti-nausea and pain medications that work much faster
• You’ve been having migraines more frequently and need a referral or a prescription for a triptan (sumatriptan, rizatriptan, etc.)
• Headache with sinus pressure, facial pain, and congestion — might be a sinus infection needing antibiotics
• Headache after a minor head bump that resolved quickly
• Medication overuse headache — taking OTC pain relievers more than 10 days per month can cause “rebound” headaches
• High blood pressure reading at home — hypertensive headache (BP-related head pain needs urgent blood pressure management)

When to Go to the Emergency Room

Some headaches are medical emergencies. These are the red flags that require immediate ER evaluation:

• “Thunderclap headache” — sudden onset, maximum severity within 60 seconds (“worst headache of my life” in a new way) — possible subarachnoid hemorrhage (brain bleed)
• Headache with stiff neck and fever — possible meningitis (a true emergency)
• Headache with confusion, altered consciousness, or personality changes
• Headache with focal neurological symptoms — weakness on one side of body, drooping face, slurred speech, double vision (possible stroke or TIA)
• Headache following a significant head injury or loss of consciousness
• Headache with vision loss
• New severe headache in someone over 50 — higher risk of serious causes
• Headache in someone with cancer or immunocompromised status
• Headache that’s progressively worsening over days/weeks

The “thunderclap” test is critical: if a headache went from zero to catastrophic in under a minute and it’s unlike any you’ve had before — ER, not urgent care.

What Urgent Care Can Do for Migraines and Headaches

This is where urgent care genuinely shines for migraine sufferers who are in the middle of a bad attack:

• Toradol (ketorolac) IM injection — a powerful injectable NSAID that cuts through severe headaches fast; often more effective than oral ibuprofen for migraine
• Compazine or Phenergan (IM or IV) — treats both the nausea and has direct anti-migraine effects
• Benadryl (diphenhydramine) IM — helps break a migraine cycle; also helps with nausea and allows rest
• IV fluids — especially if vomiting has caused dehydration (dehydration worsens migraine)
• Oral triptans (sumatriptan, rizatriptan) — prescription abortive migraine medications; we can prescribe these if you don’t have them
• Blood pressure check — for hypertensive headaches, we can prescribe or adjust BP medication
• Nasal decongestants or antibiotics — for sinus infection-related headaches

Migraine Management: The Bigger Picture

If you’re having migraines frequently (more than 4 per month), urgent care can help for individual attacks but ongoing management requires a neurologist or headache specialist. Preventive treatments (topiramate, propranolol, amitriptyline, CGRP antagonists like Aimovig) can significantly reduce migraine frequency.

Ask for a referral if your migraines are:

• Happening more than 4 times per month
• Lasting more than 72 hours
• Not responding to triptans or OTC treatment
• Causing you to miss work or normal activities regularly

Home Remedies That Actually Work for Migraines

• Dark, quiet room — reduce light and sound stimulation
• Cold compress on forehead or back of neck
• Caffeine — small amounts (1 cup of coffee) can potentiate pain relievers; avoid if you have caffeine rebound headaches
• Hydration — drink water; dehydration is a major trigger
• Ibuprofen + acetaminophen combination — evidence supports combining both for better migraine relief than either alone
• Sleep — often the most effective migraine treatment; sleeping it off is legitimate
• Peppermint oil on temples — small evidence base but well-tolerated
