WHEN TO COME IN
When Is Severe Pain an Emergency?
Severe pain is an emergency when it starts suddenly, is the worst you have ever felt, or comes with other symptoms such as fever, vomiting, trouble breathing, dizziness, fainting, sweating, or confusion. Pain after an injury that makes it impossible to use a limb, or pain that doesn’t ease with over-the-counter medicine and keeps getting worse, also needs prompt evaluation.
Pain is the body’s alarm. Sudden, severe, or unexplained pain can come from the heart, lungs, digestive system, kidneys, spine, blood vessels, or brain, and the location of the pain doesn’t always match the source. For example, a heart problem can feel like jaw, arm, or upper stomach pain.
Because the causes range from minor to life-threatening, an emergency physician looks at the whole picture: where the pain is, how it started, what makes it worse, and your other symptoms, medical history, and vital signs.
Get emergency care for pain that is:
- Sudden and severe
- The worst you have ever felt
- Paired with fever, vomiting, or sweating
- Paired with trouble breathing or dizziness
- Following a fall, crash, or other injury
- Spreading to the arm, jaw, neck, or back
- Not easing with rest or over-the-counter medicine
- Waking you from sleep or getting worse

Severe Pain? We’re Open 24/7
Emergency evaluation is available day and night at The Heights Emergency Room.
Chest, Abdominal, and Pelvic Pain
Where it hurts points to where to look.
Chest pain or pressure can signal a heart attack or a blood clot in the lung. Sudden, severe abdominal pain can come from appendicitis, gallstones, a bowel blockage, or other problems. Pelvic pain may relate to ovarian cysts, ectopic pregnancy, or kidney stones.
Back, Flank, and Head Pain
Some of the most urgent pain starts here.
Severe back or flank pain may come from a kidney stone, kidney infection, or a spinal problem. A sudden, severe headache can signal bleeding in the brain, a stroke, or another serious condition, while a typical migraine tends to build more gradually.
Pain After an Injury
Falls, collisions, and sports injuries.
Severe pain after a fall, crash, or sports injury can mean a broken bone, dislocation, or internal injury. Swelling, deformity, or inability to move or bear weight are red flags. An X-ray can show whether a bone is broken.
See our broken bone and sprain and strain pages for more.
Pain With Warning Signs
Pain plus these symptoms is more urgent.
Pain that comes with fever, vomiting, trouble breathing, fainting, a rapid heartbeat, numbness or weakness, or confusion can point to infection, a blocked organ, a heart or lung problem, or a neurologic emergency.
If you faint or nearly faint with pain, see our fainting ER page.
WHILE YOU DECIDE
What to Do (and Not Do) With Severe Pain
Don’t wait it out if the pain is alarming.
Stop what you are doing and rest in a comfortable position. Note when the pain started, where it is, what it feels like, and whether anything makes it better or worse. List your medications, and don’t drive yourself if the pain is intense or you feel faint.
Avoid taking extra pain medicine to “push through” severe pain, and hold off on large meals if you have severe abdominal pain, since you may need testing or a procedure. Follow the label directions for any medicine you take.

QUICK ANSWERS
Severe Pain Questions, Answered
When is pain bad enough to go to the ER?
Go to the ER for pain that is sudden, severe, or the worst you have ever felt, or that comes with fever, vomiting, trouble breathing, dizziness, fainting, or sweating. Pain after a major injury or pain that keeps worsening despite rest also needs prompt evaluation. For chest pain, call 911.
Can severe pain with no clear cause be serious?
Yes. Pain with no obvious cause can come from the heart, abdomen, kidneys, spine, or brain, and some serious conditions begin with pain alone. The cause often can’t be identified without an exam and testing, so don’t assume it will pass, especially if it is sudden or severe.
What tests might the ER use to find the cause of my pain?
Tests depend on where the pain is and your other symptoms. They may include an EKG, lab tests, X-rays, or an ultrasound. The physician chooses the tests that will most quickly rule out dangerous causes, and explains the results and next steps with you.
Does The Heights Emergency Room treat severe pain?
Yes. The Heights Emergency Room at 101 N Loop W #300, Houston, TX 77018, is open 24/7, with a board-certified emergency physician on site. We evaluate sudden or severe pain in adults and children, no appointment is needed, and patients who need hospital care are transferred with ambulance transport arranged by our staff.
Should I take pain medicine before going to the ER?
If you take an over-the-counter pain reliever, follow the label and don’t exceed the dose or combine products with the same ingredient. Tell the physician what you took and when. Pain medicine can mask symptoms, so don’t use it to delay care for severe pain.
EMERGENCY SAFETY
