Sore throat after school: strep or a virus?
Read moreClose
The CDC says viruses cause most sore throats. Strep throat is a bacterial infection, and it is most common in children 5 through 15. Signs that point toward strep include a sore throat that starts quickly, pain when swallowing, fever, red and swollen tonsils, white patches, tiny red spots on the roof of the mouth and swollen glands in the front of the neck. Children may also have a headache, stomach pain, nausea or vomiting.
A cough, runny nose, hoarse voice or pink eye points more toward a virus. HealthyChildren.org notes that strep cannot be diagnosed just by looking at the throat. Our clinicians can do a rapid strep test and recommend treatment, which may include prescription medicine when appropriate. See strep throat treatment.
Pollen season or a cold? Sorting it out for Clarendon Hills, IL kids

Tree-lined streets are part of the village's charm, and they make spring and fall hard on allergic kids. HealthyChildren.org says itchiness is a hallmark of allergies and not usually part of a cold. It suggests thinking about allergies when cold-like symptoms keep coming back, last more than a week or two, or return at about the same time each year.
Long-term allergy care usually starts with your pediatrician, who may refer you to an allergy specialist. We can help when stuffiness turns into ear pain or facial pain, when eyes are red and goopy, or when you need an answer on a weekend.

Your pediatrician, our clinic or the ER: a quick check
Read moreClose
The American Academy of Pediatrics suggests three questions. Is your child breathing normally? Alert and responsive? Able to drink and keep fluids down? If the answer to any is no, seek urgent or emergency care depending on how severe it is. When in doubt, call your pediatrician's office, since many have an after-hours nurse line.
Is the clinic close to the Westmont Metra station?
Yes. Westmont station is one stop west of Clarendon Hills station on Metra's BNSF Line, and our main clinic at 29 N Cass Ave is a short walk from the platform. Check the train schedule first. A parent or legal guardian should come with a child under 18.
When can my child go back to school after strep throat?
The American Academy of Pediatrics says a child with strep should stay home until at least 12 hours after antibiotics start. Your child should also be free of fever. Schools in Clarendon Hills, IL set their own rules, so check with the school office as well.
Should a toddler with a sore throat be tested for strep?
Not always. The CDC says strep throat is rare in children under 3, so a toddler's sore throat is more often caused by a virus. A clinician can examine your child and decide whether a test would help.
Can I get a school note after my child's visit?
Yes. Ask at the visit and we can provide a school note for your child, or a work note for you. Bring any district form that needs to be filled in.
How do I tell allergies from a cold in my child?
HealthyChildren.org says itchy eyes and an itchy nose point toward allergies, since itchiness is not usually part of a cold. Allergies also tend to last more than a week or two and come back at the same time each year. A cold more often brings a low fever and body aches.
