Sinus Infection Treatment in Bolingbrook, IL
Sinus infection treatment usually starts with time and home care, because viruses cause most sinus infections and most clear up in 7 to 10 days. If yours has lasted more than 10 days, got worse after it seemed to improve, or came with a high fever, our Bolingbrook, IL clinic is open every day, 8 AM to 8 PM, and walk-ins are welcome.

- Walk-ins welcome
- X-ray and rapid tests on site
- Kids and adults
- Medicare and Medicaid plans accepted
Is it a sinus infection or a cold?
Early on you often can’t tell, because a sinus infection usually starts as a cold. The difference is how long symptoms last and which way they are heading. A cold peaks and then fades over about a week. The American Academy of Pediatrics notes that mucus can turn yellow or green after 3 or 4 days of an ordinary cold, so color alone does not mean infection.
The CDC lists these common sinus infection symptoms:
- Runny or stuffy nose
- Pain or pressure in the face
- Headache
- Post-nasal drip and sore throat
- Cough
- Bad breath
Signs that point to a bacterial sinus infection
Bacteria become more likely when symptoms last more than 10 days without improving, when you feel better and then worse again, or when severe symptoms last 3 or more days, such as a fever above 102°F (39°C) with thick discharge and pain on one side of the face. These patterns come from the CDC and a 2025 review in American Family Physician. If a cough is the main problem, see our cold and cough guide.
What causes a sinus infection?
The CDC says viruses cause most sinus infections, and bacteria cause some. Your sinuses are air-filled spaces behind your forehead, nose, cheeks and eyes. When a cold or allergies make their lining swell, the openings that drain mucus can close off, and trapped mucus gives germs a place to grow.
The CDC lists these risk factors: a previous cold, seasonal allergies, smoking or secondhand smoke, nasal polyps or other structural problems, and a weakened immune system. Acute sinusitis lasts 4 weeks or less, and chronic sinusitis lasts longer than 3 months. When allergies keep setting off sinus trouble, allergy testing can show what you react to.
A cold, or a bacterial sinus infection?
| Topic | Usually a cold | Could be a bacterial sinus infection |
|---|---|---|
| How long | Peaks, then fades over about 7 days | More than 10 days with no improvement |
| Direction | A little better each day | Better for a while, then worse again |
| Fever | Rare, and if present, only at the start | Above 102°F (39°C) for 3 or more days with thick mucus |
| Mucus | Clear, may turn yellow or green after 3 or 4 days | Thick, with a blocked nose; color alone does not decide |
| Face and nose | Stuffy, runny nose and sneezing | Face pain or pressure, especially on one side |
| Antibiotics | Do not help | May help; the provider decides after an exam |
When are antibiotics needed for a sinus infection?
Antibiotics are needed only when your illness points to bacteria, and most sinus infections get better without them. The CDC’s sinus infection guidance says a clinician may suggest 2 to 3 days of watchful waiting, or may write a prescription and ask you to wait 2 to 3 days before filling it.
Antibiotics also carry risks. The CDC notes side effects that range from a rash to resistant infections and C. diff, a gut infection that causes diarrhea and can be severe. In the American Family Physician review, for every 100 adults with sinusitis who take antibiotics, about 5 benefit and about 12 have side effects.
At your visit, the provider considers how many days you’ve had symptoms, whether you have a fever and what the exam finds. If an antibiotic is likely to help, the provider can prescribe one. If not, home care is the treatment.
How to ease sinus pressure at home
Home care eases the pressure and stuffiness while the infection runs its course. The CDC and MedlinePlus suggest:
- A warm, moist washcloth over your nose and forehead
- Breathing in steam, such as sitting in the bathroom with the shower running
- Saline nasal spray several times a day
- Plenty of fluids to thin mucus
- A clean humidifier at home
Rinsing your sinuses safely
If you use a neti pot or squeeze bottle, the FDA’s advice on nasal rinsing is to use only distilled or sterile water, or tap water boiled for 3 to 5 minutes and cooled to lukewarm. Plain tap water can hold organisms, including amoebas, that survive in the nose and cause serious infections. These are rare but can be fatal.
Over-the-counter medicines
MedlinePlus warns that decongestant nasal sprays used longer than 3 to 5 days can make stuffiness worse. Acetaminophen or ibuprofen can ease face pain. Never give aspirin to a child, and ask a pharmacist before combining products if you take other medicines.
Sinus pressure not letting up?
Stop by any day, no appointment needed, and we’ll sort out whether it’s a cold, a sinus infection or something else.
When a sinus infection needs care today
Lasting, rebounding or severe symptoms need a visit. The CDC and MedlinePlus list these reasons to see a clinician:
- More than 10 days of symptoms with no improvement
- Getting better, then worse again
- A fever lasting longer than 3 to 4 days
- A severe headache or face pain that over-the-counter medicine does not help
- Symptoms still there after a full course of antibiotics
- Several sinus infections in the past year
If the worst pain is in your ear
When ear pain is the main complaint, our ear infection guide explains what to watch for. Saving a spot online ahead of time is optional.
Sinus infections in children
The AAP says a child may have bacterial sinusitis when cold symptoms, such as a runny nose or a daytime cough, last more than 10 days without improving, or when thick yellow mucus comes with a fever for 3 or 4 days. Other clues are a headache behind the eyes that gets worse when bending over, and swelling or dark circles around the eyes in the morning.
Per the AAP, a child needs a prompt call to the doctor for eye swelling or redness that lasts all day rather than just in the morning, a severe headache or pain in the back of the neck, repeated vomiting, sensitivity to light, or growing irritability, since these can mean the infection has spread. Eye swelling with a fever, or a stiff neck with a high fever, needs the ER or 911. After an antibiotic is started, symptoms should begin to ease within 2 to 3 days. If they don’t, have your child checked again.
Our pediatric urgent care treats infants, school-age kids and teenagers on a walk-in basis.
Sinus infection treatment at our Bolingbrook clinic
A sinus infection is diagnosed by history and exam, so most visits need no test. Expect questions about when symptoms began, whether you improved and then got worse, and what you have already tried. MedlinePlus describes the usual exam: looking inside the nose and tapping over the sinuses to check for tenderness.
Tests are used when another illness could explain your symptoms: a rapid strep test if a sore throat stands out, or rapid flu or COVID tests if the timing fits. All three are done on site.
Plain X-rays do not diagnose sinusitis well, according to MedlinePlus, so a sinus infection alone is not a reason for one. Our on-site X-ray matters more when a cough raises concern for pneumonia, because we can take a chest X-ray the same day, any day we’re open.
You leave with a plan: home care steps, a prescription if one is likely to help, and a clear list of changes that call for a return visit or the ER.

Questions and answers
Questions we hear often
Still not sure? Call (630) 914-5373 and we will help you decide.
Can I go to an urgent care clinic for a sinus infection?
Yes. We see adults and children with sinus infections as walk-in patients, and booking ahead online is optional. Urgent care fits most sinus infections. Skip urgent care and go to the ER for eye swelling with a fever, vision changes, a stiff neck with a high fever, or sudden confusion.
Is immediate care the same as urgent care for a sinus infection?
Yes. Locally, immediate care is simply another name for urgent care, and so is walk-in clinic. All three mean a same-day visit that needs no appointment. For a sinus infection, that visit means questions about your symptoms, an exam, a rapid strep, flu or COVID test if another illness is possible, and a treatment plan.
How long does a sinus infection last?
Most sinus infections ease on their own within 7 to 10 days, according to a 2025 review in American Family Physician. Acute sinusitis lasts up to 4 weeks, and chronic sinusitis lasts longer than 3 months. If you are not improving after 10 days, or you feel worse after starting to recover, come in to be checked.
Is a sinus infection contagious?
The sinus infection itself is not contagious, but the viruses and bacteria that can cause it are, Cleveland Clinic explains. The cold that started it can spread to the people around you, so wash your hands often, cough or sneeze into your elbow, and keep your distance from others while you are sick.
Can urgent care do an X-ray or CT scan for a sinus infection?
Our clinic has X-ray on site, but MedlinePlus notes that plain sinus X-rays do not diagnose sinusitis well, and the AAFP review advises against routine imaging. We don’t have CT or MRI equipment. If the provider is worried that an infection has spread toward the eye or brain, you will need a hospital emergency department, where CT imaging is available.
What if my sinus infections keep coming back?
Repeated sinus infections deserve a closer look. MedlinePlus says people with repeat attacks should be checked for causes such as allergies or nasal polyps. We offer allergy testing, and follow-up with primary care or an ear, nose and throat specialist may be the next step.
