• What is Urgent Care?

  • Urgent care clinics can handle a wide range of immediate medical services for treatment of illnesses or injuries that do not require a visit to a hospital emergency room. If you have a serious medical condition, go directly to the nearest emergency room or call 9-1-1. Don’t take any chances with potentially life-threatening conditions.

    Here is a list of common medical conditions that an urgent care facility can typically treat and provide services:

    • Minor cuts, scrapes, and abrasions
    • Sprains (e.g., sprained ankle or wrist)
    • Muscle strains (e.g., stretching or tearing of a muscle or tendon)
    • Fevers and headaches
    • Colds and coughs
    • Flu-like symptoms
    • Mild asthma
    • Earaches and infections
    • Rashes and bumps
    • Sore throats
    • Vomiting and diarrhea


    As noted above, an urgent care facility assists with minor medical conditions. If you have difficulty breathing, are suffering severe pain, have a deep cut, chest pain, large fractures, pregnancy problems, or other life-threatening conditions, go directly to the nearest emergency room or call 9-1-1.
