Taking care of a sprained ankle starts in the first few minutes after injury and continues for weeks afterward. Most mild sprains heal in one to two weeks with proper home care, while moderate sprains take two to four weeks and severe sprains six to eight weeks. What you do in the first 48 to 72 hours matters most for controlling swelling and setting up a smooth recovery.
Figure Out How Bad It Is
Ankle sprains fall into three grades based on how much damage the ligament sustained. A Grade 1 sprain means the ligament stretched and sustained small tears but stayed intact. You’ll feel pain and some tenderness, but you can still walk and your ankle feels stable. A Grade 2 sprain is a partial tear. Swelling is more noticeable, walking hurts, and the ankle may feel wobbly. A Grade 3 sprain is a complete rupture, with severe swelling and an inability to walk or move the ankle normally.
Certain signs mean you should get an X-ray rather than treating at home. The standard screening criteria used in emergency rooms recommend imaging if you can’t bear weight at all, if you can’t take four steps, or if you have specific point tenderness over the bony bumps on either side of your ankle. If any of those apply, you’re ruling out a fracture, not just a sprain.
The First 72 Hours
The older advice was simply “RICE” (rest, ice, compress, elevate). The updated approach, called POLICE, replaces total rest with a smarter strategy: protection plus optimal loading. The idea is that ligaments, tendons, and bone actually need some controlled movement to heal well. Complete immobilization can slow that process.
Protection: Keep weight off the ankle using crutches, a brace, or a splint. The goal is to prevent further damage, not to lock the joint down forever.
Optimal loading: Within pain limits, begin gentle movement early. This might mean small ankle circles or carefully shifting partial weight onto the foot. Crutches and braces help you control how much load you put through the joint rather than eliminating it entirely.
Ice: Apply a cold pack for 15 to 20 minutes every one to two hours during the first 48 hours. Always put a cloth or towel between the ice and your skin to prevent frostbite.
Compression: Wrap the ankle with an elastic bandage in a figure-eight pattern, starting at the foot and working upward. The wrap should feel snug but not tight. If the area below the bandage goes numb, tingles, or feels cool, loosen it immediately.
Elevation: Prop your ankle above heart level for 20 to 30 minutes, several times a day. Lying on the couch with your foot on two stacked pillows works well. This is especially important in the first 48 hours, when swelling peaks.
Managing Pain
Over-the-counter pain relievers are usually enough. Ibuprofen and naproxen sodium both reduce pain and inflammation, which makes them a common first choice. Acetaminophen handles pain but doesn’t target swelling. You can alternate or combine approaches depending on what works for you. Follow the dosing instructions on the package, and if OTC options aren’t cutting it after a few days, that’s worth a call to your doctor.
Phases of Recovery
Healing doesn’t happen all at once. It moves through distinct stages, and what you should be doing changes at each one.
Acute Phase (Days 1 to 3)
This is the POLICE phase described above. Your main jobs are controlling swelling, protecting the joint, and starting very gentle movement. Pain is the guide. If something hurts sharply, back off.
Subacute Phase (Days 3 to 7)
Swelling starts to ease. You can begin putting more weight on the ankle if it’s comfortable. Keep icing and elevating, but the frequency can decrease. Range-of-motion exercises become more important here. A simple one: sit with your foot off the ground and trace the letters of the alphabet with your big toe. This moves the ankle through its full range without loading it.
Early Rehab (Weeks 1 to 2)
Focus shifts to restoring flexibility and building early strength. Useful exercises at this stage include towel stretches (loop a towel around the ball of your foot and gently pull toward you to stretch the calf), calf raises (standing on both feet and slowly rising onto your toes), and rolling a golf ball under your foot to loosen the sole. These are low-risk movements that keep healing tissue from stiffening up.
Advanced Rehab (Weeks 2 to 6)
This is where you rebuild the strength and coordination your ankle lost. Key exercises include single-leg balance (stand on the injured foot for 30 seconds, working up to doing it with your eyes closed), marble pickups (use your toes to lift marbles off the floor into a cup), and progressive calf raises on one leg. The single-leg balance work is particularly important because a sprain disrupts your ankle’s sense of position, the internal feedback system that keeps you from rolling it again. Without retraining that system, re-injury is common.
Bracing and Taping
External support helps during both the acute phase and rehab. You have options: athletic taping, lace-up braces, and semi-rigid braces. Research comparing these options in people with moderate to severe sprains has found no meaningful difference in outcomes at six months or injury recurrence at one year. A recent trial of 161 patients with Grade 2 and Grade 3 sprains showed equivalent results across taping, semi-rigid braces, and lace-up braces.
The practical difference comes down to convenience. Taping requires someone who knows how to apply it and needs to be redone frequently. A lace-up brace is something you can put on yourself, adjust throughout the day, and reuse. For most people managing a sprain at home, a brace is the easier choice. Whichever you pick, use it during activity for as long as the ankle feels unstable, which for moderate sprains is typically several weeks.
What a Full Recovery Looks Like
A mild sprain usually resolves in one to two weeks. Moderate sprains take two to four weeks. Severe complete tears need six to eight weeks, and sometimes longer. High ankle sprains, where the injury is to the ligament connecting the two lower leg bones above the ankle joint, average 8 to 12 weeks.
Recovery isn’t just about pain going away. You’re ready to return to full activity when you can walk without a limp, hop on the injured foot without pain, and balance on one leg with confidence. Rushing back before those milestones are met is how people end up with an ankle that sprains over and over. If you’re returning to a sport, make sure you can do lateral cutting movements and jump landings comfortably before playing at full intensity.
The single biggest mistake people make with ankle sprains is treating them as minor injuries that don’t need rehab. Skipping the balance and strengthening work leaves the ankle weaker and less coordinated than before the injury, which sets the stage for chronic instability. Even a Grade 1 sprain benefits from a week or two of deliberate exercise. The time investment is small compared to dealing with repeated sprains for years afterward.
