Most flu runs its course at home with rest and fluids, and we will say so plainly rather than pretend otherwise. A small share turns into something else, and that share is what an emergency room exists for.
We run rapid flu testing with results in minutes, at any hour, with no appointment. More importantly, we can tell the difference between flu that is simply miserable and flu that has turned into pneumonia or is pushing someone toward serious trouble.
Flu becomes an emergency when breathing becomes difficult, when chest pain or pressure appears, when confusion sets in, when someone cannot keep fluids down, or when a fever improves for a day and then returns worse. That last pattern is the one most people miss.
Ordinary flu is genuinely awful and still does not need an emergency room. Body aches, a high fever, exhaustion and a cough for several days are the illness doing what it does. What matters is whether anything on the list below joins them.
The fifth line deserves attention. Flu that eases and then returns worse often means a second infection has taken hold on top of it, and that second one usually needs treating.
Arlington ER runs rapid flu testing at 1607 S. Bowen Rd., open every hour of every day with no appointment and no referral. A swab is taken from the nose, and results come back in minutes rather than days.
Being straightforward about this: if all you want is a flu test and you are otherwise well, a clinic or pharmacy will cost you considerably less than an emergency room. We would rather tell you that here than have you discover it on a bill.
Where testing here makes sense is when the result will actually change something. If you are struggling to breathe, if a fever will not break, if you are pregnant, older, or living with a lung or heart condition, then knowing quickly matters and the rest of an emergency room is available in the same visit.
It also matters at three in the morning on a Sunday, when nothing else is open and someone is getting worse rather than better. That is the situation we are built for.
Flu that has moved into the lungs behaves differently from flu alone. The clues are breathlessness, a cough producing colored phlegm, chest pain when breathing in, and a fever that returned after seeming to settle. That combination points toward pneumonia rather than flu still running its course.
The timeline is the most useful signal you have. Ordinary flu peaks around day two or three and then slowly improves. Someone who was getting better on day four and is markedly worse on day six has usually developed a second problem on top of the first.
This is where a chest X-ray earns its place, and it is the main reason a flu visit to an emergency room differs from a flu visit anywhere else. We can see whether the lungs are involved during the same visit rather than sending you away to find out.
Flu can also destabilize conditions that were previously well managed. Asthma, heart failure and diabetes all tend to worsen during a flu illness, and sometimes that, rather than the flu itself, is what needs attention.
For a healthy adult, flu is an unpleasant week. For the groups below, the threshold for being seen is deliberately lower, because complications develop faster and with less warning.
Children under five, and especially under two. Small airways narrow easily, and a child can move from coping to struggling within hours. Fast breathing or ribs visibly pulling in with each breath means come in now, not tomorrow.
Adults over sixty-five. The immune response weakens with age, and flu in an older adult carries a genuinely higher risk of pneumonia. Confusion is often the first sign families notice, before any breathing difficulty.
Anyone with a lung condition. Asthma and other chronic lung problems flare during flu, and the two together are harder to manage than either alone.
Heart conditions. Flu places real strain on the heart, and the days following flu carry a measurably raised risk of cardiac events.
Pregnancy. Changes to the immune system and lung capacity during pregnancy make flu more serious, and there is a lower threshold for assessment throughout.
Diabetes, or a weakened immune system. Blood sugar becomes harder to control during any infection, and the body has fewer defenses to work with.
If any of those describe you or the person you are worried about, do not wait for the situation to become obviously bad. Coming in early is how complications get caught while they are still straightforward.
Most of managing flu happens at home. The right-hand column covers the habits that make it worse or make it spread.
| Do this | Never do this |
|---|---|
| Note the day symptoms started | Guess the timeline once you arrive |
| Keep taking small amounts of fluid regularly | Stop drinking because you have no appetite |
| Rest properly, away from work and school | Push through and spread it around the office |
| Watch breathing rate in children closely | Assume a quiet child is simply resting |
| Come in if you improve then get worse again | Wait it out once breathing is affected |
| Wear a mask if you have to be around others | Visit an elderly relative while symptomatic |
The fluid row matters more than people expect. A high fever and rapid breathing both burn through fluid quietly, and dehydration is the complication that most often turns a manageable flu into an emergency room visit.
That last row is worth taking seriously too. Flu spreads before people feel truly unwell, and a visit to a grandparent during those first days is how a mild illness in one person becomes a serious one in another.
Your physician confirms it is flu with a rapid test, checks your oxygen level, listens to your chest and takes an X-ray where the lungs may be involved, treats dehydration with fluids, and decides whether antiviral treatment is appropriate for you.
A nasal swab, run here, with results in minutes. It also distinguishes flu from other infections that look identical.
Oxygen levels measured and lungs listened to. This is what separates flu alone from flu with a complication.
Where the lungs may be involved, on-site imaging answers it during the visit rather than days later.
Fluids through a vein when nothing is staying down, and the fever brought under control so rest becomes possible.
Antiviral treatment helps most within the first days and suits some patients more than others. Your physician weighs both.
Written guidance on what to watch for, when to return, and how long you remain infectious to others.
For most flu, urgent care or your own doctor is the right choice and will cost you less. An emergency room is for flu that has become dangerous: breathing trouble, chest pain, confusion, dehydration, or a high-risk patient getting worse.
We would rather be direct about this than take a visit that did not need to happen. A healthy adult with fever, aches and a cough who is drinking normally and breathing comfortably does not need an emergency room, and being seen in one will cost more than being seen in a clinic.
What changes the answer is any of the following: breathlessness or fast breathing, chest pain, confusion, an inability to keep fluids down, a young child struggling to breathe, or someone in a high-risk group who is deteriorating. Those situations need imaging, oxygen monitoring and intravenous fluids, and clinics generally do not have them.
Timing matters too. Flu peaks at night and on weekends, and when nothing else is open and someone is getting worse, waiting until Monday is not a reasonable plan. We are open every hour of every day for exactly that reason.
If you are unsure, call us on 817-973-7406 and describe what is happening. We will tell you honestly whether you need to come in.
The test confirms what you have. The examination and X-ray answer the more useful question of what it has caused.
Rapid tests miss some cases. If your symptoms fit flu, we treat what we see rather than what the strip says.
Children, older adults, pregnancy, lung and heart conditions. We assess these more readily rather than waiting.
Straightforward flu in a healthy adult does not need an emergency room, and we will say so rather than take the visit.
A flu visit is billed as an emergency visit plus the testing your physician orders. We accept most major private insurance plans and file the claim for you, so your share depends on your own deductible and coinsurance.
Flu is the condition where we are most likely to tell you that you did not need us, and that deserves to be said on this page rather than discovered afterward. An emergency room is more expensive than a clinic for the same flu test, and if you are a healthy adult who is drinking, breathing comfortably, and simply feeling terrible, a clinic is the better value. Nobody here will be annoyed with you for asking that question before you come in.
What an emergency room is worth paying for is the part a clinic cannot provide: oxygen monitoring, a chest X-ray during the same visit, fluids through a vein, and a physician able to act immediately if flu has turned into pneumonia. When breathing is affected or someone high-risk is deteriorating, that capability is the whole point.

Arlington ER serves Arlington, Texas from 1607 S. Bowen Rd., on the west side of Bowen just south of Pioneer Parkway. Parking is directly outside the door, which matters when you can barely stand up.
We are minutes from central Arlington and the Parks Mall, and a short drive from Dalworthington Gardens, Kennedale, Grand Prairie, and Mansfield. From I-20, exit at Bowen Road and head north. From Highway 303 or Pioneer Parkway, turn south onto Bowen and we are on your right. Our Contact Us page has anything else you need.
Please wear a mask when you arrive if you can. We are open every hour of every day, holidays included, with no appointment or referral required.
If breathing has become difficult, if the fever came back worse after easing, or if a child is breathing fast and pulling in at the ribs, that is no longer ordinary flu. Walk in and let us check the lungs properly.
Usually about fifteen minutes. The swab is taken from the nose, run here in our own laboratory, and the result is discussed with you during the same visit.
Adults are typically contagious from the day before symptoms start until about a week after. Children can spread it for longer. Staying home protects more people than any other single step.
Yes. Rapid tests miss a meaningful share of real cases, particularly early or late in the illness. Your physician treats the picture in front of them rather than the strip alone.
Most flu improves within five to seven days, with tiredness and a cough lingering longer. Getting worse after day four, or a fever returning once it had settled, is the pattern worth acting on.
Yes, and the difference is usually speed. A cold builds gradually over days. Flu tends to arrive within hours, with fever and body aches severe enough that people remember exactly when it hit.
Yes, at any age including infants. In young children we pay particular attention to breathing rate and hydration, since both change faster in children than in adults.
Yes. Ask before you leave and we will provide written documentation of your visit, which most employers and schools accept.
No need. We are walk-in only and open around the clock. Wearing a mask on arrival helps protect other patients in the waiting area, and we can provide one if you do not have it.
