A twisted ankle needs immediate action to limit swelling and protect the damaged ligament from further injury. Most ankle sprains heal well at home with the right first aid in the first 48 to 72 hours, followed by gradual movement to restore strength. Here’s exactly what to do, step by step.
First Aid in the First 48 to 72 Hours
The current best practice for a fresh ankle sprain follows the POLICE protocol: Protection, Optimal Loading, Ice, Compression, and Elevation. This replaces the older advice of complete rest, because ligaments, tendons, and muscles actually need some controlled loading to heal properly.
Protect the ankle. Stop whatever activity caused the injury. Use a brace, splint, or crutches to prevent movements that could make the damage worse. The goal isn’t to immobilize the ankle forever, but to shield it from further strain while the initial inflammation settles.
Apply ice. Place a cold pack wrapped in a cloth or towel on the ankle for 15 to 20 minutes every one to two hours during the first 48 hours. Ice narrows blood vessels, which limits swelling and bruising, and numbs the area for short-term pain relief. Never put ice directly on skin.
Compress the area. Wrap an elastic bandage around the ankle snugly enough to reduce fluid buildup, but not so tight that your toes tingle, turn blue, or go numb. If that happens, loosen the wrap immediately.
Elevate above your heart. Prop your ankle on pillows so it sits higher than your chest for 20 to 30 minutes, several times a day. This helps excess fluid drain back toward your core and noticeably reduces swelling.
Start gentle movement early. Complete rest sounds logical, but it can actually slow recovery. Light calf contractions, for example, help pump swelling up and out of the ankle. The key is finding the right balance: enough movement to support healing, not so much that you’re re-injuring the ligament.
Managing Pain Without Overdoing It
Over-the-counter pain relievers like ibuprofen, naproxen, or acetaminophen are typically enough to manage the pain of a sprained ankle. Ibuprofen and naproxen also reduce inflammation, which can help with swelling in the first few days. Follow the dosing instructions on the package and avoid stacking multiple pain relievers at once.
How to Tell How Bad It Is
Ankle sprains fall into three grades based on how much ligament damage occurred, and severity determines your recovery timeline.
- Grade 1 (mild): The ligament is stretched and slightly damaged but not significantly torn. You’ll feel pain and tenderness around the ankle, but you can still walk. Recovery takes one to three weeks.
- Grade 2 (moderate): The ligament is partially or mostly torn. Expect significant swelling, and you may not be able to walk or move the ankle normally. Recovery takes three to six weeks.
- Grade 3 (severe): The ligament is completely torn. The ankle feels unstable, and weight-bearing is extremely painful or impossible. Recovery can take several months and may require more intensive treatment.
Most twisted ankles are Grade 1 or 2. If you can hobble on it with moderate pain, you’re likely dealing with a mild to moderate sprain.
Signs You Need an X-Ray
Not every twisted ankle needs imaging. Emergency departments use a well-validated set of criteria called the Ottawa Ankle Rules to determine when an X-ray is warranted. You should get checked if you have any of the following:
- Sharp, specific tenderness when pressing on the bony bumps on either side of your ankle (the rounded knobs at the inner or outer ankle), particularly along the back edge
- Tenderness at the base of the small toe bone on the outside of your foot or the bone on the inner arch of your midfoot
- Inability to take four steps, both right after the injury and when you try again later
If you can take four steps (even painfully), and pressing on the ankle bones doesn’t produce sharp, localized pain, a fracture is unlikely. That said, if the swelling is severe, the bruising is dramatic, or something just feels wrong, trust your instinct and get it looked at.
Watch for a High Ankle Sprain
A standard ankle sprain happens when your foot rolls inward or outward. A high ankle sprain is a different injury involving the ligaments above the ankle joint, and it typically results from a collision or impact while the foot is flexed upward, not just a simple rolling motion. Symptoms include an inability to bear weight (especially going up stairs), inability to walk on your toes, and bruising that appears days after the injury rather than immediately. High ankle sprains take significantly longer to heal and almost always need professional evaluation.
When and How to Start Moving Again
Once the worst swelling subsides (usually after two to three days), you can begin gentle range-of-motion exercises. One of the simplest and most effective: sit so your feet hang off the ground, then use your injured foot to trace each letter of the alphabet in the air, leading with your big toe. Keep the movements small, using only your foot and ankle. Do two sets daily.
A full ankle conditioning program typically runs four to six weeks. Early exercises focus on restoring range of motion, then progress to strengthening the muscles around the ankle, and finally to balance and stability work. This progression matters because roughly 40% of people who sprain an ankle end up spraining it again, often because they returned to activity before rebuilding adequate strength and coordination.
The temptation is to stop doing exercises once the pain fades. Pain usually resolves well before the ligament has fully healed and the surrounding muscles have regained their protective strength. Stick with the program even when the ankle feels fine.
Bracing, Taping, and Ongoing Support
During recovery and when returning to sports, you may want external support. Lace-up braces, semi-rigid braces, and athletic tape all provide stability, and research comparing them shows no meaningful difference in outcomes. A trial of 161 people with moderate to severe ankle sprains found equivalent results at six months across all three options. A separate study of 157 adults found no difference in re-injury rates at one year between soft braces and standard taping.
Choose whichever feels most comfortable and practical. Braces are easier to apply yourself and can be reused. Tape requires some skill to apply correctly but conforms closely to the joint. Either way, external support is most useful in the first few weeks back to activity, not as a permanent crutch.
