Cold and Flu Symptoms? Our Urgent Care Clinics Have You Covered

When you're feeling miserable with a runny nose, sore throat, fever, or body aches, waiting days to see your primary care doctor isn’t ideal. That’s where urgent care comes in. With walk-in appointments and same-day treatment, urgent care clinics are a quick and reliable solution for cold and flu symptoms.
At San Antonio Regional Hospital’s urgent care clinics, medical providers evaluate your symptoms to determine whether you have a common cold, seasonal flu, or something more serious like strep throat or COVID-19. They can perform rapid diagnostic tests and recommend the right course of action—whether that’s antiviral medication, symptom relief, or further testing.
Getting treated early can reduce how long you feel sick and prevent complications like sinus infections or bronchitis. Plus, you avoid the long waits and higher costs of the emergency room.
So next time the sniffles hit hard or a cough won’t go away, head to one of our four urgent care clinics. Fast, friendly, and professional—it's the easiest way to start feeling better.
