Call 911 now if you have:

A bone is sticking out through the skin, or there is an open wound over the broken area (open/compound fracture)
The foot or toes are cold, pale, blue, or gray, or you cannot feel a pulse in the foot, signaling blood flow may be cut off
The ankle is severely deformed, bent at an odd angle, or clearly dislocated (out of joint)
New numbness, tingling, or inability to move the foot or toes, especially with severe or worsening pain
Severe, out-of-proportion or relentlessly worsening pain with a tight, tensely swollen leg or foot (possible compartment syndrome)
The injury came with heavy uncontrolled bleeding, or a high-energy trauma (car crash, fall from height) with possible other serious injuries

When in doubt about a possible emergency, call 911. Do not drive yourself.

Most ankle injuries are sprains that heal at home with RICE, but a bone poking through skin, a grossly deformed/dislocated ankle, or a cold, blue, or numb foot means go now (911).
A simple but reliable rule of thumb (the Ottawa Ankle Rules): if you cannot bear weight for at least 4 steps right after the injury and when you are seen, or you have bone tenderness on the knobby bones on either side of the ankle, an x-ray is warranted, so get evaluated.
Sprain vs. break can be hard to tell apart yourself. When in doubt, urgent care with x-ray is the sensible middle ground; deformity, open wounds, or loss of blood flow/sensation are ER or 911.

ER, Urgent Care, Doctor, or Home?

Go to the ER

The ER is the right choice when the ankle looks deformed or dislocated, you cannot put any weight on it, a bone has broken the skin, or the foot shows signs of lost blood flow or nerve function, because these need prompt imaging, reduction, and sometimes surgery. If the foot is cold, blue, numb, or the bone is exposed, call 911 rather than driving.

You cannot bear any weight or take even a few steps on the ankle after the injury
Obvious deformity, a bone that looks out of place, or you heard/felt a snap with immediate severe swelling
A visible open cut or puncture over the injured joint or bone
Numbness, tingling, or color change in the foot or toes that is present but not clearly emergent
Severe swelling and bruising that is rapidly getting worse, or pain not controlled by over-the-counter medicine
Known bleeding disorder, blood thinner use, or fragile bones (osteoporosis) with a significant injury

Urgent care

You can bear a little weight but it is very painful, and you want an x-ray to rule out a fracture
Bone tenderness on the knobby bump on either side of the ankle, or along the outer midfoot, without deformity
Moderate swelling and bruising but the foot is warm, pink, and has normal sensation
A sprain that is not improving after a couple of days of home care and you cannot quickly see your own doctor
You are not sure whether it is sprained or broken and want it checked the same day

See your doctor / telehealth

A mild-to-moderate sprain that is slowly improving but you want it evaluated or need a work/school note
Pain and swelling that have not improved (or have worsened) 2 to 3 days after the injury
A sprain not back to near-normal in 2 to 4 weeks, or that keeps giving out or feeling unstable
Repeated ankle sprains, chronic ankle instability, or lingering stiffness after a prior injury
You need referral to physical therapy or an orthopedic specialist for rehab

Safe to manage at home

Reasonable at home for a mild sprain where you can still bear weight, the foot is warm with normal color and feeling, and there is no deformity
Use RICE: Rest and avoid painful activity for the first day or two; Ice wrapped in a towel for 10 to 20 minutes several times a day; Compression with a snug (not tight) elastic wrap; Elevate the ankle above heart level
Loosen the wrap if toes tingle, go numb, or turn blue; that means it is too tight
Over-the-counter acetaminophen or an anti-inflammatory (ibuprofen/naproxen) can ease pain and swelling if you can take them safely
Begin gentle movement and weight-bearing as tolerated as pain settles; most mild sprains improve within 1 to 2 weeks

Common Causes

These are possibilities to discuss with a clinician, not a diagnosis. Only an exam and sometimes tests can tell which applies to you.

Ankle sprain: stretched or torn ligaments, most often on the outside of the ankle after a roll or twist (the most common ankle injury)
Ankle fracture: a break in one or more of the ankle bones (fibula, tibia, or talus), which can range from a hairline crack to displaced pieces
Avulsion fracture: a small chip of bone pulled off where a ligament attaches, common with twisting injuries
Fracture of the base of the fifth metatarsal or navicular in the midfoot, which can mimic an ankle injury
Muscle or tendon strain, including Achilles tendon injury, or high ankle sprain (syndesmosis)
Dislocation, where the joint surfaces are forced out of alignment, often together with a fracture

What to Expect if You Are Seen

A clinician will examine the ankle, press on specific bones, and check your ability to bear weight, plus circulation and sensation in the foot
X-rays are commonly ordered when a fracture is suspected (guided by findings like bone tenderness or inability to walk 4 steps)
If broken, you may get a splint, boot, or cast; some fractures or dislocations need reduction (realignment) or surgery
For a sprain, expect a wrap, brace, or boot, crutches if needed, and guidance on RICE and gradual return to activity
You may be referred for physical therapy, and given a follow-up plan and instructions on warning signs to watch for

Before You Go, Have This Ready

How and when the injury happened, whether you heard a pop, and whether you could walk on it right after
A list of your medications (especially blood thinners), allergies, and major medical conditions
Any prior ankle injuries, surgeries, or braces on that ankle
Loose pants or shorts and slip-on footwear so the ankle can be examined and splinted easily

Frequently Asked Questions

How can I tell if my ankle is sprained or broken?

You often cannot be sure without an x-ray. Clues that point toward a fracture include being unable to bear weight for even a few steps, bone tenderness directly on the knobby bumps on either side of the ankle, obvious deformity, or a snap at the time of injury. Pain more over the soft tissue with preserved ability to walk leans toward a sprain. When in doubt, get it imaged.

Can I still walk on it if it's broken?

Sometimes, yes. Some fractures (especially small or stable ones) still allow limited walking, and some bad sprains make walking nearly impossible. Because walking ability alone is not reliable, use the whole picture, and if you cannot take about 4 steps right after the injury, get it evaluated with an x-ray.

Should I go to urgent care or the ER?

Urgent care is a good fit for a same-day x-ray when the foot is warm, pink, has normal feeling, and there is no deformity. Choose the ER (or call 911) for obvious deformity or dislocation, a bone through the skin, a cold/blue/numb foot, or inability to bear any weight, since those may need reduction or surgery.

How long does an ankle sprain take to heal?

Mild sprains often improve within 1 to 2 weeks and heal over 2 to 4 weeks. Moderate sprains can take 4 to 6 weeks, and severe sprains or complete ligament tears may take 6 to 12 weeks or several months. Slow or stalled recovery is a reason to see a doctor or physical therapist.

Should I use ice or heat on a fresh ankle injury?

Use ice for the first 48 to 72 hours to limit swelling, applied in a towel for 10 to 20 minutes a few times a day, never directly on skin. Heat can be added later, after swelling has settled, to ease stiffness. Elevation and a snug (not tight) wrap also help early on.
