What to know before you go
Urgent care centers treat same-day, non-life-threatening illness and injury: colds and flu, sore throats, earaches, UTIs, minor cuts, sprains, and simple fractures. Bring a photo ID, your insurance card or a payment method (basic self-pay visits in Illinois typically run $100–$250 — see our Illinois urgent care cost guide), and a list of current medications. For chest pain, stroke symptoms, severe bleeding, or trouble breathing, go to an emergency room or call 911 — our urgent care vs. ER guide explains the difference.
