The most common myth about distinguishing sprains from fractures is "if you can walk on it, it's not broken." This is wrong. Plenty of fractures — particularly in the foot, ankle, ribs, and small bones of the hand — are perfectly walkable.
Symptoms of sprain and fracture overlap so substantially that imaging (usually X-ray) is often the only way to know for sure. Most extremity X-rays are quick, low-radiation, and inexpensive when done at urgent care.
Symptoms common to both
- Pain, especially with movement or weight-bearing
- Swelling around the affected joint or bone
- Bruising — sometimes immediate, sometimes hours later
- Limited range of motion
- Tenderness when you press on the area
Symptoms that suggest fracture is more likely
- Obvious deformity — the limb looks "wrong"
- Bone visible through skin (open fracture — call 911)
- Inability to bear weight at all
- Crepitus — a grinding or crackling sensation with movement
- Point tenderness directly over a bone (vs. tenderness over a ligament/tendon)
- Pop or crack heard at the time of injury
- Numbness or tingling in the limb
- Cold, pale, or pulseless limb distal to the injury
The Ottawa rules (used by clinicians)
For ankle injuries, emergency physicians use validated criteria. You'd benefit from imaging if:
- Pain in the malleolar zone AND bone tenderness at the back edge or tip of either malleolus, OR
- Inability to bear weight (walk 4 steps) at the time of injury and at the time of evaluation
The Ottawa rules don't tell you whether something IS broken; they identify when imaging is warranted.
What we do at urgent care
- History. Mechanism of injury, what happened immediately after, prior injuries.
- Physical exam. Inspect for swelling and deformity, palpate for tenderness, test range of motion, check distal pulses and nerve function.
- X-ray on site if indicated. Most extremity X-rays take under 5 minutes. Read same visit.
- Treatment: Splinting or air cast for stabilization, crutches if needed, pain control, follow-up plan.
- Referral to orthopedics if the fracture needs reduction or surgical evaluation.
When to skip urgent care and go to the ER
- Open fracture — call 911
- Severe deformity
- Cold, pale, or pulseless limb below the injury
- Suspected hip fracture (older adults after a fall who can't bear weight)
- Spine injury with significant neck or back pain after trauma
- Multiple injuries or high-energy mechanism
- Head injury with loss of consciousness, persistent vomiting, or confusion
What to do at home before coming in
The "RICE" approach:
- Rest. Don't continue to use the injured area.
- Ice. 15-20 minutes at a time, several times per day, first 48 hours.
- Compression. A wrap or ACE bandage.
- Elevation. Above heart level when possible.
- Ibuprofen or acetaminophen for pain.
Walk in for same-day injury evaluation with X-ray on site
Sage Urgent Care has a digital X-ray system on site. Most injury visits take 30-60 minutes from check-in to walking out, including imaging if needed. Open every day from 8 AM to 8 PM.

Frequently asked questions
What is the difference between a sprain and a fracture?
A sprain is a stretched or torn ligament, while a fracture is a broken bone. They cause the same swelling, bruising, and pain, which is why they are hard to tell apart without imaging.
Can I tell if it is broken without an X-ray?
Not reliably. Clues that point toward a fracture include being unable to bear weight, tenderness directly on the bone, deformity, or numbness, but an X-ray is the only way to be sure.
Do I need an X-ray for every injury?
No. Providers use clinical rules, like the Ottawa ankle rules, to decide when imaging is needed. When it is, our on-site X-ray gives you an answer within minutes.
How are sprains and fractures treated differently?
Many sprains heal with rest, bracing, and R.I.C.E. Fractures usually need immobilization with a splint or cast and sometimes orthopedic follow-up. We can start either treatment the same visit.
When should I go to the ER instead of urgent care?
Go to the ER for a bone breaking the skin, severe deformity, loss of feeling or movement, or an injury from major trauma. Otherwise, urgent care is faster for most sprains and simple fractures.
