If this may be life-threatening — chest pain, stroke symptoms, severe difficulty breathing — call 911. Paramedics begin treatment on the way and can tell the emergency room you are coming. Thoughts of harming yourself: call or text 988, any hour. Poisoning or a suspected overdose: 1-800-222-1222, Poison Control.
Three questions settle most of it. Is someone struggling to breathe, losing consciousness, bleeding in a way you cannot stop, or showing signs of a stroke or a heart attack? Call 911. Is this sudden, severe, or getting worse while you watch it? Go to an emergency room. Is this something you would take to your own doctor if it were Tuesday morning? A clinic can handle it, and you can call ahead.
Most people do not go to the emergency room too often. They go too late. So the rest of this page is written to help you go sooner rather than to talk you out of anything.
Do not drive yourself, and do not drive someone else if you can call instead. An ambulance starts treatment on the way; a car does not.
Signs of a heart attack. The Centers for Disease Control and Prevention lists chest pain or discomfort that lasts more than a few minutes or that goes away and comes back — described as pressure, squeezing or fullness rather than always as pain — along with shortness of breath, pain or discomfort in one or both arms or shoulders, pain in the jaw, neck or back, and feeling weak, light-headed or faint, sometimes with a cold sweat. It notes that women more often have unusual or unexplained tiredness, and nausea or vomiting.
Signs of a stroke. The CDC uses B.E. F.A.S.T. — Balance loss, Eye or vision changes, Face, Arms, Speech, Time. The signs it lists are sudden numbness or weakness in the face, arm or leg, especially on one side; sudden confusion or trouble speaking or understanding speech; sudden trouble seeing; sudden trouble walking, dizziness or loss of balance; and a sudden severe headache with no known cause. Note the time the first symptom appeared and tell us — the treatments that work best are only available when a stroke is recognised and diagnosed within about three hours of that moment.
And the rest of the 911 list, drawn from the National Library of Medicine’s guidance on recognising medical emergencies: someone who cannot breathe, who loses consciousness, or who is bleeding in a way that will not stop. Severe injuries, deep wounds or burns where moving the person could make the damage worse. Poisoning or choking. Swelling of the face or throat. And in a child: skin that looks blue, a fever with a stiff neck, bleeding you cannot control, or a child who cannot stand.
Anything where you genuinely believe someone could be in danger. You do not need to be right.
An emergency room is the right door when something is sudden, severe, or changing while you watch it, and when the answer needs equipment rather than an appointment. That includes chest or abdominal pain lasting more than a few minutes, breathing that is harder than it should be, a head injury, a possible broken bone, a cut that may need stitches, a burn, an allergic reaction, a high fever you cannot bring down, vomiting that will not stop, and any pain severe enough that you cannot think about anything else.
It is also the right door when the useful answer is a scan or a blood test. Both of our emergency rooms have CT, X-ray and a full laboratory in the building, staffed around the clock, which is why an answer usually arrives during your visit rather than in a few days.
A clinic is built for the things that benefit from someone knowing you: a recheck, a rash you have had for a week, blood pressure, a medication that is not agreeing with you, a physical, a child’s ear that has been bothering them since Thursday. Appointments at our clinics are by phone or through the patient portal — there is no online self-scheduler — so if you need to be seen soon, call and ask what they have.
The distinction is about what each door is built to do, not about whether your problem is important enough. Which brings up the thing this page is really about.
Coming in and being told it was minor costs you an evening. Staying home with something that was not minor can cost you permanently. Those are not equivalent, and no reasonable person should be weighing them as though they were.
So if you are stuck between two of these tiers at eleven at night, choose the higher one. Being assessed and sent home reassured is a good outcome, not a wasted trip, and nobody here will think less of you for arriving.
It is the wrong question because nobody can rank their own symptoms from the inside. An emergency is whatever it feels like to the person having it. A blocked nose is nothing at lunchtime and something else entirely when you wake at three in the morning unable to breathe through it and frightened.
You are not expected to diagnose yourself before you are allowed through the door. That is our job, and it starts the moment you arrive.
We are not a pediatric emergency room, and we treat children every day. Both halves of that sentence matter. Our emergency rooms are equipped and staffed to assess and stabilise a child, and where a child needs a specialist level of paediatric care, we arrange the transfer rather than keep them.
For anything that is not an emergency, Mercy Grace Pediatrics & Primary Care in Gilbert is built for children specifically.
Our emergency rooms are freestanding, which means they are emergency departments without an inpatient hospital attached. If you need to be admitted, we treat and stabilise you here and arrange the transfer.
That is the design rather than a limitation. There is no inpatient census competing for the team’s attention, and everybody in the building is an emergency patient.
Cost fear is the objection nobody says out loud, and it is the one that does the most damage — people sit at home with cardiac symptoms doing arithmetic. Two things are worth saying plainly.
Ability to pay is not a barrier to assessment and access to care in our emergency rooms, and by law. And an emergency visit bills at emergency rates, which are not clinic rates — we would rather tell you that now than have you discover it later.
If cost is the obstacle, say so when you arrive.

Not sure which you need? That is a reasonable question and we would rather you asked it than guessed. Call (480) 608-1649, or go to the nearest emergency room — the nearest one, not the one you usually use, and not one of ours if something closer exists. Minutes matter more than continuity.
Do I need an appointment for the emergency room? No. Both emergency rooms are walk-in, open every hour of every day.
What if I am not sure it is an emergency? Come in. This page is not an exhaustive list and you are not expected to diagnose yourself.
Should I drive or call an ambulance? For anything on the 911 list above, call. Paramedics begin treatment on the way and can alert the emergency room before you arrive.
Will I be turned away if I cannot pay today? No. Ability to pay is not a barrier to assessment and access to care in our emergency rooms, and by law.
Can I bring my child to one of your emergency rooms? Yes. We are not a pediatric emergency room, and we treat children every day.
What if I need to be admitted to a hospital? We treat and stabilise you here, then arrange the transfer.
Not sure where to go? Start with the nearest door. Both of our emergency rooms are open 24 hours a day, every day of the year, with CT, X-ray and a full laboratory in the building and a board-certified provider seeing every patient. Find your nearest location →

Ability to pay is not a barrier to assessment and access to care in our emergency rooms — by law. An emergency visit bills at emergency rates, which are not clinic rates, and we would rather tell you that now than have you find out afterwards.
If anything you receive after a visit is unclear, call the facility you were seen at before you pay it. They hold the record of your visit, and they would rather explain a statement than have you pay something you do not owe.
