How Do You Take Care of a Sprained Ankle?

A sprained ankle heals best with a combination of short-term protection and early, controlled movement. The old advice to ice it and stay off it for weeks has been largely replaced by a more active approach that gets you moving sooner while still respecting the injury. The specifics depend on severity, but the broad principle is the same: brief rest, then progressive loading. Most sprains recover well without surgery, though skipping rehabilitation is where people run into long-term trouble.

What Actually Happens When You Sprain Your Ankle

A sprain is a stretch or tear of one or more ligaments, the tough bands that hold bones together at a joint. In the ankle, the most common type is a lateral sprain, which happens when the foot rolls inward. That sudden inversion stretches the ligaments on the outside of the ankle, most often the anterior talofibular ligament (ATFL).¹ Video analysis of basketball players sustaining ankle sprains has shown two main patterns: a sudden inversion with internal rotation, and a similar inversion without the rotational component. The first pattern tends to damage both the ATFL and the calcaneofibular ligament (CFL), while the second strains the CFL alone.²

These injuries happen fast. Video analysis of tennis players caught mid-sprain found peak inversion angles reaching well over 100 degrees in some cases, with the ankle rolling at speeds above 500 degrees per second.³ Your muscles simply cannot react quickly enough to prevent the ligament from stretching beyond its limit. That is why sprains happen even to well-conditioned athletes.

First Steps After the Injury

In the first couple of days, your priorities are reducing pain, limiting swelling, and protecting the damaged ligament from further stress. The approach sports medicine professionals now recommend is captured by the acronym PEACE and LOVE, which replaced the older RICE (Rest, Ice, Compression, Elevation) framework in 2019. PEACE stands for Protection, Elevation, Avoid anti-inflammatory modalities, Compression, and Education. LOVE stands for Load, Optimism, Vascularization, and Exercise.⁴ The shift is meaningful: instead of telling you to rest passively for a week, the emphasis is on protecting the ankle briefly, then gradually introducing movement and weight-bearing as pain allows.

Here is what the first 48 to 72 hours look like in practice:

Protect: Avoid activities that increase pain. Use crutches if you need them, but full immobility is not the goal.
Elevate: Keep the ankle above heart level when you can to help drain swelling.
Compress: An elastic bandage or compression sleeve can help control swelling. Evidence on the best type of compression is limited, but single studies have shown it reduces swelling and improves quality of life.⁵
Load early: As soon as you can tolerate it, begin putting weight on the ankle. Gentle walking with support counts.

The Ice Debate

If you have always reached for an ice pack after a sprain, you are not alone. Ice remains deeply embedded in sports and rehabilitation culture. But the evidence supporting it is surprisingly thin. A systematic review of randomized controlled trials found only marginal evidence that ice combined with exercise helped after ankle sprains, and little evidence that adding ice to compression made a meaningful difference.⁶ A more recent review focused specifically on acute ankle sprains reached a similar conclusion: the evidence that cryotherapy improves swelling, pain, or range of motion beyond what other treatments achieve was uncertain at best.⁷

The PEACE and LOVE framework explicitly discourages cryotherapy, but ice is still widely used in practice.⁸ The reasoning behind avoiding it is that inflammation in the early phase is part of the healing process, and aggressively suppressing it might slow tissue repair. That said, if ice is the only thing you have for pain relief in the first hour or two, applying it briefly is unlikely to derail your recovery. The honest picture is that ice is not harmful in moderate doses; it just may not do as much as people assume.

When to Get an X-Ray

Not every sprained ankle needs imaging, and emergency departments have a reliable tool for making that call. The Ottawa Ankle Rules are a set of clinical criteria that help determine whether you need an X-ray to rule out a fracture. They check for bone tenderness at specific points around the ankle and midfoot, and whether you can bear weight for four steps. Multiple systematic reviews confirm the rules catch nearly all fractures, with sensitivity approaching 100%, meaning they almost never miss a break.⁹ ¹⁰ If you pass the Ottawa rules, you almost certainly do not have a fracture, and the sprain can be managed without radiation exposure.

One thing clinical exams tend to miss is the severity of moderate sprains. An MRI comparison study found that physical examination was perfectly accurate at identifying severe (grade III) ligament tears, but only about a quarter of grade II tears were correctly identified on examination alone. Clinicians most often underestimated the damage, and associated injuries like capsule tears or tendon damage were frequently overlooked.¹¹ This matters because if your ankle is not improving as expected after a couple of weeks, the injury may be worse than originally graded, and imaging may be warranted.

Support and Bracing Beat Casting

For years, moderate sprains were often put in a plaster cast. Research has turned decisively against that approach. A trial comparing functional treatment (elastic support, early movement exercises) with cast immobilization for grade I and II sprains found that the functional group had less pain at six weeks, better ankle function scores, used fewer painkillers, and missed fewer days of work.¹² Even for complete ligament ruptures, a randomized trial found that functional treatment led to faster return to activity, fewer symptoms at three and six months, and better improvement in joint stability, with no difference in reinjury rates compared to casting.¹³

The practical takeaway is to use a lace-up brace or semi-rigid ankle support rather than rigid immobilization. A systematic review comparing braces to other functional supports found that braces offered modestly better functional outcomes, though the differences between types of functional support were small.¹⁴ The key message is not that one specific brace is best; it is that keeping the ankle lightly supported while allowing movement produces better results than locking it in place.

Pain Management

Most people reach for ibuprofen or naproxen after a sprain, and these do help with pain and swelling in the short term, up to about two weeks.¹⁵ But a meta-analysis comparing topical and oral anti-inflammatory medications in injured athletes found a meaningful surprise: topical gels and creams reduced pain significantly more than pills when both were compared to placebo. Oral medications did not reach a statistically significant reduction in pain versus placebo at all in that analysis.¹⁶ Head-to-head comparisons of topical and oral NSAIDs have found similar effectiveness for both acute and chronic injuries, but oral NSAIDs cause more gastrointestinal side effects while topical formulations mainly produce local skin reactions.¹⁷

The practical implication: try a topical anti-inflammatory gel first. You get comparable or better pain relief at the ankle with fewer systemic side effects. Oral options like ibuprofen remain reasonable if you need broader pain control, especially if swelling is the main problem, but they are not clearly superior for the sprain itself.

One caveat worth noting is that the PEACE and LOVE framework advises caution with anti-inflammatory medications in the very early phase, since some inflammation supports healing. The tension here is real but manageable. If you are in significant pain, managing it is reasonable. Just do not take maximum-dose NSAIDs around the clock for weeks on autopilot.

Rehabilitation and Balance Training

Rehabilitation is the most underrated phase of ankle sprain care. Many people stop paying attention to the injury once the pain fades, but this is exactly when the work that prevents future problems should begin. The general progression moves through range-of-motion exercises, strength training, and proprioceptive (balance) work.

Early rehabilitation focuses on regaining full ankle motion and maintaining muscle strength. Alphabet exercises, where you trace letters with your toes, are a simple starting point for range of motion. Resistance band exercises for the muscles around the ankle come next, followed by calf raises and eventually single-leg balance drills. The goal is to restore not just strength but the ankle’s sense of its own position in space, which is often disrupted after a sprain.

The evidence for balance training is strong, particularly for preventing future sprains. Two separate meta-analyses found that proprioceptive training programs reduced the rate of repeat ankle sprains by about 36% in people with a sprain history.¹⁸ ¹⁹ This is one of the most reliable interventions in all of sports medicine. Standing on one leg on a wobble board or unstable surface for a few minutes a day is genuinely protective, and it costs almost nothing.

Chronic Ankle Instability

The biggest risk of poorly managed ankle sprains is chronic ankle instability, where the ankle keeps giving way or feeling loose months or years later. A large proportion of people who suffer a lateral ankle sprain develop lingering symptoms that feed into this cycle.²⁰ The condition involves both mechanical looseness in the ligaments and a deficit in the brain’s ability to sense the ankle’s position, which makes it easy to roll the ankle again.

A retrospective study of 362 patients identified several factors that predict who develops chronic instability after a first sprain. Higher body mass index, younger age, bone marrow lesions on the talus, moderate joint swelling, and injury to the posterior talofibular ligament all increased the odds.²¹ Similarly, for syndesmotic (high) ankle sprains, deltoid ligament involvement and higher BMI were strong predictors of chronic instability.²² If you fall into any of these categories, taking rehabilitation seriously is especially important.

High Ankle Sprains Are a Different Animal

Not all ankle sprains involve the same ligaments. A high ankle sprain (syndesmotic sprain) damages the ligaments that connect the two leg bones just above the ankle joint. These injuries often happen when the foot is planted and the leg twists outward, and they take considerably longer to heal than standard lateral sprains. An MRI study found that syndesmotic injuries occur across all sprain grades, with about 40% appearing even in grade I sprains.²³

Rehabilitation for high ankle sprains follows a similar overall path but typically requires a longer period of protected weight-bearing before progressing to balance and agility work. These injuries are less common than lateral sprains but are frequently underdiagnosed because clinicians may not think to test for them if the lateral ligaments are also damaged.

Deciding When to Return to Activity

One of the most common mistakes is going back to sports or intense exercise too soon. An international panel of experts developed a framework called PAASS for making return-to-sport decisions after lateral ankle sprains. It assesses five domains: pain during and after activity, ankle range of motion and strength, the athlete’s own confidence and psychological readiness, balance and proprioceptive control, and sport-specific functional performance like hopping and agility drills.²⁴

Despite the existence of frameworks like PAASS, there is surprisingly little consensus on objective thresholds. A systematic review found that while experts agreed on the need to assess sport-specific movement, only two papers provided an actual threshold, such as the injured leg performing at 80% or more of the uninjured leg on hop tests.²⁵ Functional tests like single-leg balance, the star excursion balance test, and agility tests can give you and your physiotherapist a clearer picture of readiness than pain alone.²⁶

A sensible self-check: can you hop on the injured ankle without pain, change direction quickly, and complete a full practice session at your sport? If any of those trigger discomfort or if the ankle feels unreliable, you are not ready. Returning on a partially recovered ankle is one of the clearest paths to chronic instability.

When Surgery Enters the Picture

The vast majority of ankle sprains, even severe ones, heal without surgery. But for a small subset with significant ligament disruption, operative repair may produce better long-term results. A long-term follow-up study tracked patients with severe lateral ankle ligament injuries over more than a decade. Among those treated surgically, about 17% experienced re-sprains, though none required additional surgery. In the non-surgical group, about 32% experienced re-sprains, and a slightly higher number developed chronic instability.²⁷ The authors recommended surgical treatment for patients with very high talar tilt angles on stress X-rays, a marker of severe instability that suggests the ligaments are unlikely to tighten sufficiently on their own.

For the average sprain, surgery is not on the table. It becomes relevant when a sprain is truly severe and mechanical instability persists despite months of rehabilitation, or when imaging shows a degree of ligament disruption that non-surgical care is unlikely to fully resolve.

The Psychological Side of Recovery

An overlooked aspect of ankle sprain recovery is the mental component. People who have had multiple ankle sprains show increased levels of injury-related fear and reduced psychological well-being compared to those who have never sprained an ankle.²⁸ This fear can cause changes in movement patterns, such as landing more stiffly or avoiding planting the foot forcefully, which paradoxically increases reinjury risk. If you find yourself avoiding activities you used to enjoy because you do not trust the ankle, that is a signal worth addressing, either through graded exposure in rehabilitation or through conversation with a clinician who takes it seriously. The PAASS return-to-sport framework explicitly includes psychological readiness as one of its five domains for good reason.

Children’s Ankle Injuries

In children and adolescents, what looks like a sprain on X-ray is sometimes assumed to be a growth plate fracture, because the growth plates near the ankle are still open and vulnerable. A study of 135 children with lateral ankle injuries that appeared normal on X-ray found that actual growth plate fractures were rare, occurring in only about 3% of cases. The vast majority, around 80%, actually had ligament injuries, meaning true sprains.²⁹ This is relevant because many children with negative X-rays end up in a cast and referred to orthopedics under the assumption of a growth plate injury that was never actually there. A more measured approach, one that considers the high likelihood of a simple sprain, could spare many kids unnecessary immobilization.

Prevention After Recovery

Once you have sprained an ankle, you are at higher risk of spraining it again. Balance training is the single best preventive measure, as covered earlier. External support can also help. A study of high school football players compared prophylactic bracing to taping over a full season and found no difference between the two in preventing sprains; both groups had very low injury rates.³⁰ Since braces are reusable and taping requires skill and daily application, bracing is the more practical long-term option for most people.

The combination of daily balance exercises and wearing a brace during higher-risk activities gives you the strongest protection. Neither measure is a guarantee against another sprain, but together they substantially shift the odds in your favor.
