Walk-in urgent care ยท St. Louis

Walk-in urgent care in St. Louis, with X-ray, lab and infusion under one roof

Express Urgent Care is a walk-in clinic in St. Louis, next to the airport, for injuries and illnesses that need prompt care but are not life-threatening. It is open Monday through Friday, 7 AM to 7 PM, with on-site X-ray, laboratory testing and an IV infusion center inside the clinic.

Some problems cannot wait for your regular doctor and do not belong in an emergency room. The sprained ankle. The cut that needs closing. The fever that will not break. The sports physical due Friday. Express Urgent Care exists for exactly that gap.

It is a walk-in clinic on Woodson Rd in St. Louis, next to Lambert International Airport, staffed by board-certified specialists. No appointment. No referral. Walk in, register online before you arrive, or schedule online. The clinic's stated standard is care within 15 minutes of registration. Its reputation rests on more than 100 Google reviews, and it bills itself as one of the best-rated urgent care facilities in the St. Louis area.

The clinic is one of the practices led by Dr. Gurpreet Singh Padda, MD, MBA, MHP (background). His interventional pain practice is in the same building. Urgent care handles the acute injury. The Institute handles pain that has not resolved.

What does Express Urgent Care treat?

Injuries

Abrasions, animal bites, blisters, bruises, burns, concussions, cuts, dislocations, embedded objects, fractures, infected wounds, insect stings, muscle strains, splinters, sports injuries and sprains.

In practice that means bracing a sprain, X-raying and splinting a fracture, cleaning and closing a laceration, dressing a minor burn. A workplace accident and a weekend injury get the same treatment.

Illnesses

Allergies and asthma. Cold and flu, with testing. Cough and bronchitis. Earache and ear infections. Fever and chills. Headache and migraine. Sore throat, strep and laryngitis, with rapid strep testing. Nausea, vomiting and diarrhea, with IV fluids when needed.

Patients of every age are seen, children included.

Acute pain

Acute pain is a signal. It comes from an injury, an infection such as sinusitis, a dental problem or a UTI, the days after surgery, or a flare of arthritis, fibromyalgia, migraine or nerve pain. The clinic assesses the source, treats it with medication and advice, and sets out follow-up. When pain refuses to leave, it is a different problem: see interventional pain management.

Addiction

Initial support for alcohol, opioid, stimulant, benzodiazepine and other substance use: counseling, medication-assisted treatment, medication management, and referral to specialized care. The full in-person program is at Addictionology Center.

When do you go to the ER instead?

Urgent care is not an emergency room. The wrong door costs time that matters. Call 911 or go to the nearest emergency department, and do not drive to this clinic, for:

Unsure? Call (314) 886-5290. The staff will tell you honestly where you should be.

How does a walk-in visit work?

Walk in any time, Monday through Friday, 7 AM to 7 PM. Register online first and your paperwork is done before you reach the door, so check-in is shorter. You can also call ahead en route to pre-book.

The advantage of a clinic with its own X-ray and lab is simple arithmetic. When the exam turns up something that needs a test, the test happens in the same visit. No second appointment. No second drive. The clinic's own standard for any urgent care: examine, test and treat in one visit.

What physicals are done here?

Physical paperwork is always due tomorrow. The coach needs it before the game. The employer will not schedule you without it. Your regular doctor cannot see you for three weeks.

Walk-in physicals cover:

Bring the form you were handed, a photo ID and your medication list. A parent or guardian signs for a minor. The form is completed, signed and goes home with you. A straightforward physical is usually done in well under an hour from registration.

A sports physical here is not a rubber stamp. It covers personal and family cardiac history, blood pressure, vision, heart and lungs, abdomen and a musculoskeletal screen, the things that occasionally matter before a teenager runs sprints in August heat. If something needs follow-up, you hear it and get help arranging it.

What occupational health services are offered?

Pre-employment screenings, drug testing and workers' compensation evaluations, plus injury treatment and ongoing health monitoring. Employee health programs include TB testing, hepatitis A and B vaccination, pre-employment and random drug testing, alcohol testing, X-ray, CT and ultrasound services, sports physicals and tetanus shots.

What imaging and lab tests are on site?

Digital X-ray, including bone, chest and abdominal films, for fractures, arthritis, bone infection, pneumonia and kidney, liver, stomach, intestinal or bladder concerns. The clinic's imaging list also includes CT for trauma evaluation and cancer staging, ultrasound for internal structures and muscle, and fluoroscopy for barium studies, cardiac catheterization and arthrography. X-ray doses are minimal, but tell staff about pregnancy and any recent imaging.

The on-site lab runs strep, COVID-19, flu, mono, pregnancy, glucose, urinalysis and blood work. A diagnosis made while you are still in the building means treatment starts on a result, not a guess.

What is the infusion center inside the clinic?

An IV infusion center sits inside the urgent care, so treatment that would otherwise mean a hospital happens here. IV delivery skips the gut and goes straight into the bloodstream.

More on scheduled infusion programs across the network: infusion therapy.

What vaccines are given?

Annual flu vaccine for everyone six months and older, hepatitis A and B, Tdap, MMR, tetanus and diphtheria boosters, COVID-19, and vaccines required for travel, for all ages.

Is STD and STI testing available without an appointment?

Yes. Walk in, tell the desk you are there for testing, and you are seen like any other patient. You do not explain yourself. Results are protected health information like every other record.

Most sexually transmitted infections cause no symptoms. That is precisely why waiting until something feels wrong is the wrong strategy. The clinic tests for chlamydia, gonorrhea, syphilis, HIV, trichomoniasis, hepatitis B and hepatitis C, and evaluates discharge, burning with urination, pelvic or testicular pain, sores and unexplained rashes.

Several tests result during the visit. The rest come back within a few days, and the clinic calls either way, negatives included. Indicated treatment starts the same day, and some infections are treated on suspicion. Partner notification and retesting are part of the visit, because treating one partner and not the other is how reinfection happens. After a specific exposure, timing matters: some infections are not yet detectable, so you are told when to come back instead of being handed a meaningless result.

Does urgent care check for concussion?

Yes. A concussion is a brain injury, and most happen without anyone losing consciousness. A hit in a game, a fall at home, a rear-end collision on I-70: any can leave a headache that will not lift, a fog, light that feels too bright, sleep that stops working.

The evaluation covers your symptoms, thinking and memory, balance and eye movements, and a neurological exam, with a careful history of how it happened, because mechanism tells the physician where to look. If it looks like more than a concussion, X-ray is on site and imaging and specialist referral are arranged. A physician sees walk-ins the same day.

You leave with a written plan: the first 48 hours, staged return to screens, school and exercise, what brings you back, and when sport is safe. Returning too early is what turns a manageable injury into a lasting one. The clinic coordinates the plan with your school, team, employer and doctor.

Emergency signs, call 911: loss of consciousness, worsening headache, repeated vomiting, seizure, weakness or numbness, slurred speech, unequal pupils, clear fluid from the nose or ears, or someone who cannot be woken.

Symptoms that persist for weeks go to the Concussion Center. Crash and work injuries go to Accident and Injury Experts.

Why screen for heart, stroke and diabetes?

Every 36 seconds, someone in the U.S. dies from cardiovascular disease. Diabetes, heart disease and stroke rank among the top causes of illness and death worldwide, and their risk factors, blood pressure, cholesterol and blood sugar, are silent until they are not. Find them early and they can be managed or prevented.

The screening menu:

The packages: the Primary Package at $159 covers the carotid scan, PAD test, AAA test and atrial fibrillation test. The Men's Comprehensive at $249 adds kidney disease, PSA, testosterone and a liver panel. The Women's Comprehensive at $249 adds kidney disease, osteoporosis, hs-CRP, A1c and thyroid. Signing up for texts unlocks special package pricing of up to 50% off individual screenings.

The tests are quick and painless, results are available right away, and a team member reviews them with you and sets out the lifestyle changes and preventive steps that follow. The deeper metabolic work lives on the pain and metabolic medicine hub.

Can I be seen virtually?

Yes, for conditions that do not need lab work or a full exam: acne, cold sores, cough, cold, flu and strep, pink eye, rashes and skin infections, sinus infections, UTIs, seasonal allergies, migraine, gout attacks, high blood pressure, high cholesterol, hypothyroidism, birth control and emergency contraception, anxiety and depression prescription renewals, quitting smoking, and more. Follow-ups after a clinic visit work the same way. When a virtual problem needs hands on, you are moved to an in-person visit.

Can I get DOT paperwork done the same day?

Come in. Severe pain from an injury or a condition like migraine is assessed quickly and treated with the medication or treatment it needs, with guidance on managing it afterward.
