A badly sprained ankle, typically a grade 2 or grade 3 injury, involves a partial or complete tear of one or more ligaments. Recovery takes anywhere from several weeks to several months depending on severity. The priority in the first few days is protecting the injury and managing swelling, then gradually shifting toward restoring movement, strength, and balance.
How Bad Is Your Sprain?
Ankle sprains are graded on a three-point scale based on how much damage the ligament sustained. A grade 1 sprain is a slight stretch or minor tear. The ankle feels stable, and you can usually walk with minimal pain. A grade 2 sprain is a partial but incomplete tear, with moderate swelling, bruising, and pain when walking. The ankle may feel somewhat stable but is tender to the touch. A grade 3 sprain is a complete rupture of the ligament. Expect severe swelling, significant bruising, and intense pain. The ankle feels unstable and may “give out” when you try to stand on it.
If you’re searching for how to treat a “badly” sprained ankle, you’re likely dealing with a grade 2 or 3. One useful self-check: if you couldn’t take four steps immediately after the injury, or if pressing along the bony ridges on either side of your ankle produces sharp, specific pain, that’s a signal to get an X-ray. These are the same criteria emergency departments use to rule out a fracture.
Immediate Care: The First 72 Hours
The older advice you may have heard, RICE (rest, ice, compression, elevation), has been updated. A framework published in the British Journal of Sports Medicine now recommends an approach called PEACE for the acute phase. It stands for Protection, Elevation, Avoid anti-inflammatory modalities, Compression, and Education. The key difference from RICE is what it tells you to avoid.
Here’s what to do right away:
- Protect the ankle. Stop all activity that causes pain. Use crutches if you can’t bear weight. For grade 3 sprains, a walking boot or rigid brace may be needed for the first week or two.
- Elevate it. Keep the ankle above heart level as much as possible to help fluid drain away from the injury.
- Compress it. An elastic bandage wrapped snugly (not tightly) around the ankle reduces swelling. A compression sleeve works too.
- Be cautious with ice. While ice can help with pain, there’s no high-quality evidence that it speeds healing. It may actually interfere with the inflammatory process your body needs to begin tissue repair, potentially delaying recovery. If the pain is severe, short applications (10 to 15 minutes) are reasonable for comfort, but don’t ice aggressively around the clock.
- Limit anti-inflammatory painkillers early on. Inflammation in the first 48 to 72 hours isn’t a malfunction. It’s your body sending repair cells to the damaged tissue. Taking ibuprofen or similar medications during this window can blunt that response. If pain is hard to manage, acetaminophen is a better choice in the first few days since it controls pain without suppressing inflammation.
After the First Few Days
Once the initial swelling starts to plateau (usually around day 3 to 5), the focus shifts. The same framework uses the acronym LOVE for this phase: Load, Optimism, Vascularisation, and Exercise. In practical terms, this means you should start putting controlled stress on the ankle rather than keeping it completely still.
Begin with gentle weight-bearing as pain allows. Complete immobilization beyond the first few days can actually slow recovery by weakening the surrounding muscles and stiffening the joint. Pain is your guide: if an activity causes a sharp increase, back off. A dull ache during movement is generally acceptable.
Light cardiovascular activity that doesn’t stress the ankle, like upper-body exercises or swimming, helps increase blood flow to the healing tissue. This matters because improved circulation delivers the nutrients and oxygen your ligaments need to rebuild.
Rebuilding Strength and Balance
This is the phase most people skip, and it’s the reason so many “bad” sprains lead to repeat injuries. When a ligament tears, it damages the nerve endings responsible for proprioception, your ankle’s ability to sense its own position in space. Without targeted rehab, that awareness doesn’t fully come back on its own, leaving you vulnerable to rolling the ankle again.
A structured progression looks like this:
Weeks 1 through 4: Start with seated exercises. One effective technique is the short foot exercise: while sitting with both feet flat on the floor, try to shorten your foot by pulling the ball of your foot toward your heel without curling your toes. Hold for 5 seconds, repeat 12 times, rest 2 minutes, and do 3 sets. Perform this three times a week. It stimulates the nerve pathways in the sole of your foot and improves the stability signals your brain receives from the ankle.
Weeks 5 through 8: Progress to standing on both feet for the same exercise, then advance to single-leg stance. At this point, you can also begin standing on an unstable surface like a balance pad or wobble board. Start with both feet, then move to one foot as confidence builds.
Weeks 8 and beyond (for grade 3 injuries): Add dynamic balance challenges like single-leg hops, lateral movements, and sport-specific drills if you’re an athlete. A grade 3 sprain typically needs several months before full return to demanding activity.
One practical tip that research supports: massaging the sole of your foot for a few minutes before your rehab exercises can improve outcomes by roughly 30%. It primes the sensory receptors in your foot, making the balance training more effective.
Bracing and Support During Recovery
For a badly sprained ankle, external support during the healing period and when returning to activity is important. The two main options are athletic tape and lace-up ankle braces. Research comparing the two hasn’t produced a clear winner. One study of nearly 300 football players found that lace-up braces cut the risk of re-injury in half compared to tape, but another study found no significant difference.
In practice, a lace-up brace has some real advantages over tape for most people. It maintains consistent support throughout the day (tape loosens within 20 to 30 minutes of activity), it’s easier to apply yourself, and it’s reusable. A semirigid brace with stirrup-style supports is another option, particularly for grade 3 injuries in the early weeks.
Plan to wear a brace during physical activity for at least 6 to 12 months after a severe sprain, even after you feel “normal.” The ligament tissue takes much longer to fully mature than the pain takes to resolve.
Recovery Timelines
Grade 2 sprains generally take 4 to 8 weeks before you can return to most normal activities, though full ligament healing continues beyond that. Grade 3 sprains take several months. High ankle sprains, which involve the ligament connecting your two shin bones above the ankle joint, tend to be the slowest, sometimes requiring 3 to 6 months.
The biggest mistake with a severe sprain is returning to full activity based on how the ankle feels rather than how it performs. Pain often fades well before the ligament has regained its structural integrity and before your proprioception has been retrained. A good test before returning to sport or high-demand activities: can you do 10 single-leg hops on the injured ankle with confidence and no instability? If not, you’re not ready.
Roughly 40% of people who suffer a significant ankle sprain go on to develop chronic ankle instability, meaning the ankle continues to “give way” during normal activities. Nearly all of that risk comes from inadequate rehabilitation, particularly skipping the balance and proprioception work. The sprain itself heals. The real long-term damage comes from not retraining the ankle’s position-sensing system afterward.
