What Is Headache and Its Treatment?

Care that brings real relief fast and rules out the conditions that can hide behind a stubborn headache.


Headache treatment at RapidCare ER focuses on easing the pain, figuring out what’s actually driving it and ruling out emergencies like a stroke, brain bleed, meningitis or dangerously high blood pressure. Depending on your situation, your visit may include a thorough neurological exam, blood work, blood pressure checks, a CT scan when needed and IV medication if the pain is severe.

Once your provider has a clear picture, they’ll walk you through pain relief, IV migraine therapy when appropriate, blood pressure management, fluids if dehydration is part of the picture and clear next steps, including any neurology referral worth scheduling. Each plan is built around what’s truly behind the headache.

Care may include:

Focused Headache Assessment

Your visit begins with a private conversation about how the pain feels, where it sits, when it started, what made it worse and any other symptoms tagging along, vision changes, nausea, weakness or stiff neck.

Neurological Exam

A careful neuro check and on-site CT imaging when needed help your provider rule out serious causes quickly without sending you to another facility.

IV Migraine and Pain Relief

IV medications like ketorolac, anti-nausea support and migraine-specific cocktails can break severe pain in minutes, far more effective than oral medicine when you can’t keep anything down.

Follow-Up and Referral Guidance

Before discharge, you’ll receive clear instructions covering prescriptions, headache triggers, warning signs to track and any neurology referrals worth scheduling.

When to Visit the ER for Headache Treatment

Visit the ER when a headache hits hard, comes on suddenly or arrives with other warning signs.

Plenty of headaches settle with rest, water and OTC pain relievers, but certain types call for emergency care. If your headache feels different, is severe or comes with concerning symptoms, RapidCare ER in San Antonio is open and ready.

1

Worst Headache of Your Life

A sudden, severe “thunderclap” headache that hits maximum intensity within seconds can signal a brain bleed or aneurysm and needs immediate evaluation.

2

Headache With Stroke-Like Symptoms

A headache paired with face drooping, arm weakness, speech changes, vision loss or confusion can be a sign of stroke and needs immediate emergency care.

3

Headache With Stiff Neck

A pounding headache combined with a stiff neck and fever can be an early warning of meningitis and needs urgent attention.

4

Headache After a Head Injury

A headache that develops or worsens after a fall, blow or accident can suggest a concussion or brain bleed and warrants prompt evaluation.

5

Migraine That Won’t Break

Severe migraine pain that hasn’t responded to home treatments (especially with vomiting that prevents oral medication) needs IV-level care.

6

Severe Hypertension

Sudden vision loss, double vision or extremely high blood pressure paired with headache can point to serious conditions that need urgent evaluation.
