A sprained ankle needs protection and rest for the first one to three days, followed by a gradual return to movement and weight-bearing as pain allows. Mild sprains typically heal within one to two weeks, while severe tears can take several months. What you do in the first 72 hours and the rehab weeks that follow makes a real difference in how fully your ankle recovers.
How to Tell How Bad It Is
Not all ankle sprains are the same. The severity depends on how much damage the ligament sustained, and this determines your recovery timeline and how aggressively you need to treat it.
A Grade 1 sprain means the ligament is stretched or slightly torn. You’ll notice mild tenderness, some swelling, and stiffness, but the ankle feels stable. Walking with minimal pain is usually possible. A Grade 2 sprain involves a more significant but still incomplete tear. Expect moderate pain, swelling, bruising, and tenderness when you touch the injured area. Walking hurts. A Grade 3 sprain is a complete tear of the ligament. The ankle is unstable, swelling and bruising are severe, and walking is likely impossible because the joint gives out under your weight.
If you can’t put any weight on your ankle immediately after the injury, if pressing on the bony knobs on either side of your ankle produces sharp pain, or if you can’t take four steps, you should get an X-ray. These are the criteria emergency doctors use to rule out a fracture, and meeting even one of them warrants imaging.
What to Do in the First 72 Hours
The modern approach to soft tissue injuries has moved beyond the old RICE method (rest, ice, compression, elevation). Sports medicine experts now recommend an approach called PEACE for the immediate phase, which better reflects what your body actually needs to heal.
Protect it. Limit movement for one to three days to reduce bleeding into the tissue and prevent further damage to the injured ligament fibers. This doesn’t mean total immobilization. Prolonged rest actually weakens the tissue, so use pain as your guide: once it starts easing, begin moving again.
Elevate it. Keep your ankle above heart level when you’re sitting or lying down. This helps drain fluid away from the swollen area. Prop your foot on a stack of pillows while you sleep or rest on the couch.
Avoid anti-inflammatories early on. This one surprises most people. Inflammation is your body’s repair mechanism, and suppressing it with anti-inflammatory medications in the first few days may actually slow long-term healing, especially at higher doses. Ice falls into this category too. If swelling is severe, brief icing for comfort is reasonable, but aggressive icing to eliminate all inflammation can be counterproductive.
Compress it. Wrap the ankle with an elastic bandage or use compression tape. This limits swelling inside the joint and has been shown to improve quality of life after ankle sprains. Wrap firmly but not so tightly that your toes go numb or turn blue.
Educate yourself. An active recovery, where you gradually start using the ankle again, consistently outperforms passive treatments like ultrasound therapy, acupuncture, or prolonged manual therapy. Those approaches show minimal benefit for pain and function compared to simply getting moving again when your body is ready.
When Pain Relief Makes Sense
After the first two to three days, if pain is keeping you from sleeping or beginning gentle movement, over-the-counter pain relief can help. Ibuprofen is typically taken as 400 mg initially, then 200 to 400 mg every four hours as needed, up to four doses in 24 hours. Naproxen starts at 440 mg, then 220 mg every 8 to 12 hours, with a maximum of 660 mg per day. Don’t use either for more than 10 days without medical guidance, and if you’re over 65, stick to no more than 220 mg of naproxen every 12 hours.
Acetaminophen (Tylenol) is a reasonable alternative for pain relief without any anti-inflammatory effect, which makes it a better choice in the first couple of days if you need something to take the edge off.
Returning to Movement
Once the initial pain and swelling start settling, the goal shifts. Your ankle now needs controlled stress to rebuild. Loading the joint with movement and exercise promotes repair and remodeling of the damaged ligament. The key is to add activity gradually without pushing through sharp pain. Normal activities should resume as soon as symptoms allow.
Your mindset matters here more than you might expect. People who approach recovery with optimism and confidence consistently have better outcomes. Fear of re-injury, catastrophic thinking (“my ankle will never be the same”), and avoiding movement out of anxiety can genuinely slow healing. The ligament needs to be loaded to get stronger. Gentle, progressive use is treatment, not a risk.
Three Exercises That Rebuild Stability
The biggest long-term risk after an ankle sprain isn’t lingering pain. It’s re-spraining the same ankle because the joint’s balance sensors (proprioception) were damaged along with the ligament. These exercises, developed by UCSF’s orthopaedic sports medicine program, specifically retrain that stability system. Start them once you can stand on the injured foot without significant pain.
Single Leg Balance
Stand on the injured leg on a flat surface. Hold your balance for 30 to 60 seconds, then rest and repeat. Once that feels easy, progress to standing on a pillow or couch cushion, or try it with your eyes closed. Do 2 to 3 sets once or twice a day. This is the single most important exercise for preventing future sprains because it directly retrains the ankle’s position-sensing ability.
Calf Raises
Stand with the balls of your feet on the edge of a step. Slowly rise up onto your toes, hold for 3 seconds, then lower back down. Work toward doing these on just the injured leg. Aim for 3 sets of 15 reps, once or twice daily. This rebuilds the strength of the muscles that actively stabilize the ankle during walking and running.
Single Leg Squats
Stand on the injured leg on a flat surface (or a cushion for more challenge). Slowly bend into a half squat to about 45 degrees, hold for 3 seconds, and return to standing. Do 2 to 3 sets of 15 reps, once or twice a day. This exercise strengthens the entire chain of muscles from your hip to your ankle that controls how your leg absorbs force.
Recovery Timeline by Severity
A mild (Grade 1) sprain typically heals within one to two weeks. You’ll likely be walking normally within a few days and can return to exercise once balance and strength feel close to your uninjured side. A moderate (Grade 2) sprain generally takes several weeks, with a gradual return to activity as pain and swelling allow. Bruising may linger after the pain has mostly resolved.
A severe (Grade 3) sprain, where the ligament is completely torn, can take several months to recover. Some complete tears require surgery, particularly if the ankle remains unstable after a course of rehabilitation. Even without surgery, expect a longer period of protected weight-bearing and a more structured rehab program before returning to sports or high-demand activities.
Regardless of the grade, continuing balance and strengthening exercises for at least six to eight weeks after the pain resolves significantly reduces your risk of spraining the same ankle again. Most re-sprains happen because people stop rehabbing once the pain is gone, before the ligament and the surrounding stabilizing system have fully recovered.
