Our symptom guides help you decide what to do next: care for it at home, visit urgent care or call 911. Pick a symptom to see common causes, home care that helps and when to come in. Urgent Care Center of Westmont sees walk-in patients in Westmont, IL, 7 days a week.
Most mild symptoms that are improving can be cared for at home.
Come in when a symptom lasts longer than expected, gets worse after getting better, or needs a test to sort out.
Babies, older adults and people with long-term health conditions should be checked sooner.
Emergency warning signs are listed at the bottom of every guide and mean call 911.

Our team is led by board-certified physicians. The guides do not replace an exam, but they help you choose the right next step.

Many symptoms come from short-lived viruses or small strains and get better on their own. Home care is usually enough when:
You are eating and drinking and can keep fluids down
Pain or fever is controlled with over-the-counter medicine used as the label says
You feel a little better each day
You do not have a long-term condition that raises your risk
MedlinePlus notes that many children run high fevers with mild viral illnesses, and that a fever is part of the body's defense against infection. How someone acts often tells you more than the number on the thermometer.
When to come to urgent care
Read moreClose
A symptom lasts longer than expected, such as a fever over 3 days or sinus pain over 10 days
You start to get better, then get worse again
You need a test to know what's wrong, like strep, flu, a UTI or an X-ray
Pain keeps you from sleeping, working or walking
You need a work or school note
MedlinePlus lists colds, flu, earaches, sore throats, low-grade fevers, limited rashes, sprains, back pain and minor cuts and burns as problems urgent care handles well. Not sure? Use our Urgent care or ER? tool.

Babies, young children and older adults can get sick faster and show it differently. A child who is unusually sleepy or fussy, or an older adult who is newly confused or weak, should be checked sooner. Read when to take your child to urgent care for a fever and see our kids and teens page.

Common questions
How do I know if my symptoms need a doctor?
See a doctor if a symptom is severe, lasts longer than expected, gets worse after improving or keeps you from normal activities. A fever over 3 days, pain that won't ease with over-the-counter medicine and trouble keeping fluids down are common reasons to come in. Anything listed under the warning signs below means call 911.
Should I go to urgent care for a fever?
Often, yes. Urgent care is a good choice for a fever that lasts more than 3 days, comes with ear pain, a sore throat or burning when you pee, or makes you feel very unwell. For a child, how they act matters as much as the number. Our fever guide explains more.
Can I use a symptom guide instead of a visit?
A guide helps you decide what to do next, but it can't examine you or run a test. If you are unsure, it is safer to be seen. Our clinicians can check you, test when it helps and recommend treatment in one walk-in visit at our Westmont, IL clinics.
What should I tell the clinician about my symptoms?
Tell us when the symptom started, what makes it better or worse, what you have tried, and any fever readings with times. Bring a list of your medicines and allergies. For a rash or symptom that comes and goes, phone photos help. Our what to bring checklist covers the rest.
“I had to visit the clinic on a Saturday and they were super fast, clean, kind and got me in and out of there fast even with an almost full waiting room! Michael at the front desk was super helpful and went out of his way to make sure I was taken care of and comfortable until I could be seen by the doctor. Definitely 5 star care!!”
