What to Do If You Think You Sprained Your Ankle

A suspected ankle sprain calls for a few immediate actions: protect the ankle from further damage, let pain be your guide for how much weight to put on it, and watch for signs that the injury might be something more serious than a simple sprain. Most lateral ankle sprains heal well with early movement, support, and targeted exercises over the following weeks. But what you do in the first hours and days matters more than most people realize, and what you skip during recovery can set you up for re-injury that lingers for years.

The First Few Minutes

If you roll your ankle during a run, a game, or just stepping off a curb, stop what you’re doing. Continuing to play or walk on a freshly injured ankle risks turning a mild sprain into a worse one. Sit down, take your shoe off if possible (swelling can make removal harder later), and take stock of what happened. Can you put any weight on it? Is there immediate bruising or deformity? Does the pain feel like it’s centered on one of the bony bumps on either side of your ankle, or is it more in the soft tissue?

That bony-bump question is more important than it sounds. Emergency departments use a screening tool called the Ottawa Ankle Rules to decide whether an X-ray is needed. The rules focus on specific spots: if you have tenderness right over the tip or back edge of either ankle bone (the malleoli), or over certain bones in the midfoot, or if you can’t take four steps, an X-ray is warranted. A systematic review found these rules have close to 100% sensitivity for catching fractures, meaning they almost never miss a broken bone, and using them reduces unnecessary X-rays by roughly 30 to 40 percent.¹ A pooled analysis of multiple studies confirmed sensitivity above 96% for detecting ankle fractures.²

In practical terms: if the pain is mostly in the soft, fleshy area in front of and below the ankle bone, and you can hobble a few steps (even painfully), you probably don’t have a fracture. But if you can’t bear weight at all, if you feel tenderness right on the bone, or if the ankle looks visibly deformed, get to an emergency room or urgent care for imaging.

Ice, Rest, and the Shifting Advice

For decades, “RICE” (rest, ice, compression, elevation) was the standard advice. More recently, sports medicine has moved toward a framework called PEACE & LOVE, which stands for Protection, Elevation, Avoid anti-inflammatories, Compression, and Education in the acute phase, followed by Load, Optimism, Vascularisation (cardiovascular exercise), and Exercise in the subacute phase. One notable change: the newer framework discourages routine icing, even though ice remains widely used in sports and rehabilitation settings.³

The evidence on ice is honestly thin. A systematic review of randomized trials found little evidence of an optimal mode or duration of icing, and only marginal evidence that ice combined with exercise helped after ankle sprains.⁴ Another systematic review found uncertain evidence that cryotherapy improved swelling, pain, or range of motion beyond what other treatments already provided.⁵ That said, one trial did find that intermittent icing (ten minutes on, ten minutes off, repeated) offered better short-term pain relief during activity than a straight 20-minute application.⁶

So where does that leave you? Ice probably won’t hurt your recovery, and if it feels good and reduces pain enough for you to start moving sooner, that’s a reasonable trade. But don’t treat it as essential medicine. If you do ice, use a cloth barrier and apply it in short intervals rather than parking a bag of frozen peas on your ankle for half an hour straight. Compression (an elastic bandage or sleeve) and elevation are less controversial and can help manage the swelling that tends to peak in the first 48 to 72 hours.

Should You Take Anti-Inflammatories?

Reaching for ibuprofen or naproxen after a sprain feels automatic, and these drugs do help with pain and swelling in the short term. Evidence suggests oral NSAIDs are more effective than placebo at improving pain and swelling up to about two weeks, though longer-term effects aren’t well established.⁷ The concern that keeps coming up in sports medicine circles is that inflammation is part of the healing process: damping it down too aggressively with anti-inflammatories could theoretically slow tissue repair. Animal studies have shown short-term benefits with NSAIDs after acute injury alongside potential long-term drawbacks to tissue structure.⁸

In humans, though, a review of the evidence found insufficient proof of a harmful effect on soft tissue healing when NSAIDs are used at standard doses for two weeks or less.⁹ The practical takeaway: a short course of over-the-counter NSAIDs for pain control is reasonable, especially in the first few days when pain is worst. Just don’t lean on them for weeks on end, and consider acetaminophen as an alternative if you’re mainly looking for pain relief without the anti-inflammatory effect. If you’re uncertain, your doctor or pharmacist can guide you based on your medical history.

When to Get Imaging

Most people with a garden-variety lateral ankle sprain don’t need advanced imaging. If the Ottawa Ankle Rules suggest no fracture and you can bear some weight, standard clinical assessment is usually enough for a mild to moderate sprain. The catch is that physical examination, while quite good at identifying severe (grade III) ligament tears, is only about 25% accurate at diagnosing moderate (grade II) injuries, often underestimating the damage.¹⁰ So if your ankle isn’t improving as expected after two or three weeks, imaging becomes more useful.

Ultrasound has emerged as a strong option here. A meta-analysis comparing ultrasound and MRI for diagnosing tears of the main lateral ligament (the anterior talofibular ligament) found that ultrasound was actually more sensitive, around 97% compared to roughly 87% to 89% for MRI, and costs considerably less.¹¹ However, for severe injuries where complete ligament tears or associated cartilage damage are suspected, MRI provides a fuller picture and remains the better choice.¹²

Early Movement Beats Prolonged Rest

One of the most consistent findings in ankle sprain research is that getting the joint moving relatively early leads to a faster recovery than keeping it locked down in a cast or rigid boot. A randomized trial comparing early mobilization to immobilization for first-time lateral sprains found that the early movers were far more likely to be back at full work within ten days (54% versus 13%), had less pain at three weeks, and showed no difference in re-sprain rates a year out.¹³ A more recent meta-analysis pooling over 1,100 patients across ten trials found no significant differences in pain or functional improvement between functional treatment and immobilization, reinforcing that you don’t need a cast for most sprains.¹⁴

“Early movement” doesn’t mean ignoring pain and going for a jog. It means controlled, gentle motion: ankle pumps, alphabet tracing with your foot, and gradually increasing weight-bearing as pain allows. Some kind of external support helps during this phase. A trial that tested different bracing strategies found that combining a semi-rigid stirrup brace with an elastic wrap returned patients with mild and moderate sprains to normal walking and stair climbing in about half the time compared to using either one alone.¹⁵ For severe sprains, the same trial found that a semi-rigid brace or a short period in a walking cast (about ten days) followed by bracing produced similar outcomes. When it comes to choosing between a lace-up brace and athletic tape for support, both appear to offer similar protection against re-injury over the following year.¹⁶

High Ankle Sprains Are a Different Animal

Most ankle sprains involve the lateral (outside) ligaments. A “high ankle sprain,” or syndesmosis injury, involves the ligaments connecting the two lower-leg bones just above the ankle joint. These take longer to heal and are more commonly seen in contact sports. A study tracking high ankle sprains found that patients with stable injuries returned to sports in a mean of 45 days, while unstable injuries averaged 64 days and often required surgical fixation.¹⁷ The same study found that instability was roughly 9.5 times more likely with a positive “squeeze test” (pain when the calf is compressed above the injury) and 11 times more likely with concurrent deltoid ligament damage on the inner ankle.

If your pain is above the ankle joint rather than below it, centered between the two bones of your lower leg, or if it hurts when you rotate your foot outward, you may have a high ankle sprain and should see a sports medicine provider rather than toughing it out. Trying to return too soon from a syndesmosis injury is a recipe for prolonged pain and poor healing.

Why Balance Training Is the Most Underrated Part of Recovery

Once the acute pain subsides and you can stand comfortably, the most valuable thing you can do is start balance and proprioception exercises. Proprioception is your body’s sense of where your joints are in space; a sprain disrupts it, and without targeted retraining, that disruption can persist and set you up for future sprains. Standing on one foot, using a wobble board, and progressing to single-leg squats and hops on unstable surfaces all rebuild this sense.

The evidence here is strong. A controlled trial of a balance board training program found it effective at preventing recurrent ankle sprains.¹⁸ Another study of high school athletes found that those who performed a balance training program cut their sprain risk roughly in half, and athletes with a history of prior sprains had double the baseline risk, making the training even more important for them.¹⁹ This is the kind of rehab that most people skip because it feels boring or unnecessary once the pain goes away. Skipping it is probably the single most common mistake after an ankle sprain.

Chronic Ankle Instability and Why “It’s Just a Sprain” Is Misleading

The casual attitude many people take toward ankle sprains has consequences. Failed rehabilitation after an acute sprain is a primary driver of chronic ankle instability, a condition where the ankle repeatedly gives way, feels unreliable, and is prone to recurrent sprains.²⁰ This instability can stem from physical looseness in the ligaments (mechanical instability), deficits in the ankle’s proprioceptive and neuromuscular systems (functional instability), or both.²¹ Either way, abnormal joint mechanics can follow, with both excessive looseness and compensatory stiffness contributing to changes in how the ankle moves.²²

This is why the balance training discussed above matters so much. Chronic instability isn’t inevitable after a sprain, but it’s common enough that treating a sprain casually, walking it off and assuming it’ll sort itself out, is genuinely risky. The research consistently points to targeted neuromuscular rehabilitation as the best protection against the ankle becoming a recurring problem.

Children’s Ankle Injuries Need Extra Attention

In kids and adolescents whose growth plates haven’t yet closed, what looks like a simple sprain on X-ray can sometimes involve an injury to the growth plate itself. A study using MRI on children with ankle injuries that appeared normal on X-ray found that about 3% had growth plate fractures that imaging had missed.²³ All four patients with these hidden fractures also had associated ligament injuries. While 3% is a small number, the potential consequences of a missed growth plate injury make it worth keeping an eye on a child’s recovery. If your kid’s ankle isn’t clearly improving within a week or two, or if they’re having trouble bearing weight beyond what you’d expect for a sprain, an MRI may be warranted.

Knowing When You’re Ready to Return to Activity

One of the frustrating gaps in ankle sprain research is that, despite how common these injuries are, there’s no universally validated set of criteria for when it’s safe to return to sport. A systematic review specifically looking for studies that used criteria-based return-to-sport decision-making after lateral ankle sprains found none.²⁴ In practice, most people return when the pain feels manageable, which isn’t the same thing as being ready.

An international consensus framework called PAASS offers the most structured approach available. It maps return-to-sport readiness across five areas: pain (during sport and in the 24 hours after), ankle impairments (range of motion, strength, power), the athlete’s own perception of confidence and stability, sensorimotor control (balance and proprioception), and sport-specific functional performance (hopping, cutting, completing a full training session).²⁵ Functional tests like the star excursion balance test, agility T-test, and single-leg hop tests can give you and your clinician objective markers to track.²⁶

Even if you’re not a competitive athlete, the logic of this framework applies. Before you go back to hiking, pickup basketball, or your morning run, you should be able to hop on the injured ankle without pain, cut and change direction confidently, and complete an activity session without the ankle swelling up or hurting afterward. “It doesn’t hurt when I walk” is a low bar.

The Foot Position That Sets You Up for Re-Injury

A biomechanics study found that increased plantar flexion at the moment your foot hits the ground (essentially landing on your toes rather than your heel) significantly increased the occurrence of ankle sprains.²⁷ This toe-down landing pattern may be one reason previously sprained ankles are so susceptible to re-injury, and it also helps explain why braces and tape work: they limit the ankle’s ability to drop into that vulnerable position at impact. If you’ve sprained your ankle before, paying attention to how your foot lands during sports, especially when jumping or stepping on uneven ground, is a low-tech strategy that costs nothing and addresses one of the actual mechanisms of injury.

The Psychological Side of Repeated Sprains

People who have sprained their ankle more than once tend to carry a psychological burden that doesn’t show up on any imaging. A systematic review found that individuals with a history of multiple lateral ankle sprains reported greater injury-related fear and decreased psychological health compared to people who had never been injured, while those who had sprained just once showed no significant psychological differences from healthy controls.²⁸ Fear of re-injury can alter how you move, making you tentative in ways that paradoxically increase your risk. This is why the PAASS return-to-sport framework includes the athlete’s self-reported confidence and psychological readiness as core assessment domains, not as an afterthought.

What Ankle Sprains Cost

Ankle sprains are often dismissed as minor injuries, but the financial reality is anything but trivial. A systematic review of the economic literature found that direct costs of ankle sprain management ranged from $292 to $2,268 per patient in 2016 dollars, depending on severity and the treatment approach taken.²⁹ That range doesn’t account for lost wages, reduced productivity, or the costs of treating chronic instability down the road if the initial injury is managed poorly. The cheapest ankle sprain is the one you rehabilitate properly the first time.
