Sprained Your Ankle? What to Do in the First 48 Hours

If you just sprained your ankle, the first thing to do is stop putting weight on it and protect it from further damage for the next one to three days. Most ankle sprains heal well without surgery, but what you do in the first 48 hours and the weeks that follow makes a real difference in how quickly you recover and whether the ankle stays stable long-term.

The First 48 Hours

The modern approach to soft tissue injuries is built around two phases, summarized by researchers in the British Journal of Sports Medicine as PEACE and LOVE. The first phase, PEACE, covers what to do right away:

  • Protect: Limit movement and avoid putting weight on the ankle for one to three days. This minimizes bleeding inside the tissue and prevents further tearing. Don’t overdo the rest, though. Prolonged immobilization actually weakens the healing tissue.
  • Elevate: Prop your ankle above the level of your heart whenever you’re sitting or lying down. This helps fluid drain away from the swollen area.
  • Avoid anti-inflammatories: This one surprises most people. Inflammation is your body’s repair process. Taking anti-inflammatory medications (like ibuprofen) in the early days can interfere with tissue healing, especially at higher doses. Ice falls into this category too. If you use ice at all, keep it brief and for pain relief only.
  • Compress: Wrap the ankle with an elastic bandage or use compression taping. This limits swelling and has been shown to improve comfort and quality of life after ankle sprains.
  • Educate yourself: Recovery works best with an active approach. Passive treatments like ultrasound, acupuncture, or manual therapy in the early phase have minimal effects on pain and function compared to simply moving the ankle as tolerated.

How to Tell if It’s Broken

Not every sprained ankle needs an X-ray. Emergency departments use a set of criteria called the Ottawa Ankle Rules to decide. You likely need imaging if you have tenderness when pressing on the bony bumps on either side of your ankle (the back edge or the tip), tenderness at the base of the small bone on the outside of your foot or the bone on the inner arch, or if you couldn’t take four steps right after the injury. If you can walk four steps, even with a limp, a fracture is unlikely.

Mild, Moderate, and Severe Sprains

Ankle sprains are graded by how much ligament damage has occurred, and the grade shapes your recovery timeline.

A Grade 1 sprain means the ligament is stretched or slightly torn. You’ll have mild tenderness, some swelling, and stiffness, but the ankle feels stable and you can usually walk with minimal pain. These typically heal in one to two weeks.

A Grade 2 sprain is a partial tear. Expect moderate pain, noticeable swelling, bruising, and tenderness when touched. Walking is painful. The ankle may feel somewhat unstable. Recovery takes several weeks.

A Grade 3 sprain is a complete tear of one or more ligaments. Swelling and bruising are severe, the ankle gives out when you try to stand, and walking is usually not possible. Recovery can take several months, and surgery is sometimes necessary.

High Ankle Sprains Are Different

Most sprains happen when the ankle rolls inward, damaging the ligaments on the outside. A high ankle sprain is a different injury entirely. It involves the ligaments above the ankle joint that hold the two shin bones (tibia and fibula) together. These injuries result from a rotational force rather than a simple roll.

High ankle sprains are more serious because the damaged ligaments are responsible for keeping the leg stable every time you stand. They take at least twice as long to heal as a typical sprain, roughly three weeks to four months or longer in severe cases. A doctor can test for this type of injury by squeezing the calf and rotating the foot to see if it reproduces pain higher up.

When to Start Moving Again

The second phase of recovery, LOVE, is about gradually loading the ankle back up:

Load it early. Begin putting weight on the ankle as tolerated within a few days. Early weight bearing and gentle movement produce much better outcomes than keeping the ankle immobilized for a long time. In fact, excessive immobilization is a known cause of chronic ankle pain. For Grade 3 injuries, a slightly longer period of protection is reasonable, but the goal is still to start moving as soon as pain allows.

Stay optimistic. This sounds soft, but it matters clinically. Fear of re-injury, catastrophic thinking, and depression are real barriers to recovery. People who expect a good outcome tend to have one.

Get your heart rate up. Pain-free aerobic exercise, like cycling or swimming, should start within a few days. Cardiovascular activity increases blood flow to the injured area and helps maintain fitness and motivation during recovery.

Rehab Exercises That Prevent Re-Injury

This is the part most people skip, and it’s the part that matters most for long-term ankle health. Up to 34% of people who sprain their ankle will sprain it again within a year. The main reason is that the initial injury disrupts your body’s position-sensing system (proprioception), leaving the ankle vulnerable even after the pain is gone.

Balance training is the single most effective way to restore that stability. The American Academy of Orthopaedic Surgeons recommends single-leg balance exercises six to seven days a week during recovery. Stand on the injured leg near a counter or wall for support, lift the other foot, and try to hold your balance for up to 30 seconds. Remove your hands from the support surface when you can, replacing them as needed. Aim for three to five repetitions per session. Doing this without shoes increases the challenge.

Other useful exercises include ankle circles to restore range of motion, calf raises to rebuild strength, and resistance band exercises where you push your foot outward against the band to strengthen the muscles that resist inward rolling. Once recovery is complete, continuing these exercises three to five days a week serves as long-term protection.

Bracing and Taping for Return to Activity

When you’re ready to return to sports or higher-intensity activity, external support reduces your risk of re-injury. Both athletic taping and semi-rigid braces work, and both are significantly better than no support at all. Research comparing the two has found braces to be slightly more effective, with the added advantages of being reusable, easier to apply yourself, and more consistent in support over the course of a workout (tape loosens as you sweat).

A lace-up or semi-rigid brace is a practical choice for most people returning to activity after a sprain. You don’t necessarily need to wear it forever, but using it during the first few months of return to sport gives the healing ligament extra protection while your balance and strength catch up.
