If you’ve just sprained your ankle, the first thing to do is stop putting weight on it and protect it from further damage. Most ankle sprains heal well without medical intervention, but how you handle the first few days matters for how quickly and completely you recover. Here’s what to do right now and in the weeks ahead.
Decide If You Need an X-Ray
Not every sprained ankle needs imaging. Emergency departments use a set of criteria called the Ottawa Ankle Rules to determine whether an X-ray is warranted. You likely need one if any of the following apply: you couldn’t bear weight right after the injury, you can’t take four steps now, or you have sharp tenderness when pressing directly on the bony bumps on either side of your ankle or on the heel bone. If none of those apply and you can walk, a fracture is unlikely and you can manage the injury at home.
These rules don’t apply to children under five, people with reduced sensation in their feet (such as from diabetes), or anyone who was intoxicated or unable to communicate clearly at the time of injury. In those cases, get evaluated regardless.
How Bad Is It? Understanding Sprain Grades
Ankle sprains fall into three grades, and knowing which one you’re dealing with helps set expectations for recovery.
- Grade 1: The ligament is stretched or slightly torn. You’ll have mild tenderness and swelling, but the ankle feels stable and you can usually walk with minimal pain.
- Grade 2: A partial but incomplete tear. Expect moderate pain, swelling, and bruising. The ankle is tender to the touch, and walking hurts.
- Grade 3: A complete ligament tear. Swelling and bruising are severe, the ankle feels unstable or “gives out,” and walking is likely not possible due to intense pain.
Most sprains are inversion injuries, meaning the foot rolled inward and damaged the ligaments on the outside of the ankle. This is by far the most common type. Less frequently, the foot rolls outward (eversion), which can injure the inner ankle ligaments or even cause a fracture, since the ligament on that side is extremely strong and may pull a chip of bone loose rather than tear. Eversion injuries can also damage the ligaments higher up between the two shin bones, known as a high ankle sprain, which takes significantly longer to heal.
What to Do in the First 1 to 3 Days
Current sports medicine guidance for soft tissue injuries follows a framework called PEACE, published in the British Journal of Sports Medicine. The priorities during the first few days are straightforward.
Protect it. Limit movement and avoid putting weight on the ankle for one to three days. This minimizes bleeding inside the tissue and prevents you from making the tear worse. But don’t rest longer than necessary. Prolonged immobilization weakens the healing tissue. Let pain be your guide for when to start moving again.
Elevate it. Keep your ankle above the level of your heart when you’re sitting or lying down. This helps drain fluid away from the swollen area.
Compress it. Wrap the ankle with an elastic bandage or use compression taping. This limits swelling and has been shown to improve comfort after ankle sprains.
Skip the ice (or use it cautiously). This may surprise you, since icing a sprain is deeply ingrained advice. But there’s no high-quality evidence that ice improves healing of soft tissue injuries. Inflammation is actually part of how your body repairs damaged ligaments. Ice may provide temporary pain relief, but it can also disrupt the repair process by slowing down the immune cells that clean up damaged tissue and begin rebuilding. If you do ice for pain, keep sessions short.
Pain Relief Without Slowing Healing
The same logic applies to anti-inflammatory painkillers like ibuprofen and naproxen. While they reduce swelling, that swelling is part of the healing response you actually need. Ankle sprains are not driven by the same inflammatory pathways that make these drugs effective for conditions like gout or arthritis. Acetaminophen (Tylenol) manages pain just as well for mild to moderate sprains without interfering with tissue repair. It’s a reasonable first choice, especially in the early days when your body is doing its most active healing work.
If pain is severe enough that over-the-counter options aren’t helping, that’s worth a medical visit, both for pain management and to rule out a more serious injury.
What to Do After the First Few Days
Once the initial pain and swelling start to settle, usually within a few days, the goal shifts from protection to controlled movement. The second phase of recovery follows the LOVE framework: load, optimism, vascularization, and exercise.
Start loading the ankle early. As soon as you can do so without sharp pain, begin putting weight on the ankle and moving it through its range of motion. Mechanical stress on healing ligaments actually stimulates better repair. The tissue remodels itself along the lines of force applied to it, building back stronger and more organized. Avoiding movement too long leads to weaker, stiffer healing.
Get your heart rate up. Pain-free cardiovascular activity, even something as simple as cycling or swimming, increases blood flow to the injured area and has been shown to reduce the need for pain medication. Start a few days after the injury if you can do it without aggravating the ankle.
Stay mentally positive. This sounds like generic advice, but research consistently shows that psychological factors like fear of re-injury and catastrophic thinking are real barriers to recovery. Expecting a good outcome is associated with actually having one.
Rehabilitation Exercises
Structured rehab exercises should continue for six to eight weeks, even after the pain is gone. This is the part most people skip, and it’s the main reason ankle sprains so often become recurring injuries. A sprain damages not just the ligament but also the nerve receptors that tell your brain where your foot is in space. Without retraining that sense of position (proprioception), your ankle remains vulnerable.
Strengthening
Use a resistance band anchored to a sturdy object. Sitting in a chair, rotate your foot inward, outward, and pull your toes up toward you against the band’s resistance. Do three sets of 15 repetitions, once or twice a day. Calf raises on a step are also effective: rise onto your toes, hold for three seconds, then lower slowly. Work toward doing these on a single leg. Single-leg half squats to about 45 degrees build the muscles that stabilize the ankle during dynamic movements.
Balance Training
Stand on one leg on a flat surface and hold for 30 to 60 seconds. Once that’s easy, progress to standing on a pillow or couch cushion, or close your eyes. For a more challenging drill, place six small targets in a half circle about 30 inches away from your standing foot and slowly tap each one with your free foot while balancing. Another progression: stand on one leg with a slight knee bend and slowly reach toward the ground with your hand while keeping your torso straight, then return to standing. Aim for two to three sets of each exercise, once or twice daily.
As symptoms improve, gradually reintroduce activities like cycling, the elliptical, and stair climbing before returning to higher-impact sports.
Preventing Re-Injury
Ankle sprains have a high recurrence rate, and a previous sprain is the single biggest risk factor for the next one. Wearing an ankle brace during sports is one of the most effective preventive measures. Studies comparing taping and bracing have found that braces are slightly more effective than tape, though both reduce injury risk compared to no support. Braces also have the practical advantage of not loosening during activity the way tape does.
Continuing balance and strengthening exercises beyond the initial rehab period provides lasting protection. The proprioceptive training you do in the weeks after a sprain has benefits that persist as long as you maintain it.
When a Sprain Becomes a Bigger Problem
Most ankle sprains, even grade 2 injuries, heal within a few weeks. Mild sprains typically resolve in one to two weeks. Complete ligament tears can take several months, particularly if surgery is needed.
Surgery is uncommon after a first sprain. It’s generally reserved for people who develop chronic ankle instability, meaning the ankle repeatedly gives way during walking or activity, keeps spraining, or causes ongoing pain despite completing physical therapy and trying supportive bracing or orthotics.
Seek immediate medical attention if you notice numbness, tingling, or loss of sensation in your foot, if the skin below the injury turns pale or feels cold, or if you experience pain that seems far out of proportion to the injury and keeps getting worse despite rest and elevation. These can signal compartment syndrome, a rare but serious complication where pressure builds inside the tissue and cuts off blood flow. Pain that escalates beyond what you’d expect and doesn’t respond to any pain relief is the earliest and most reliable warning sign.
