Learn how to heal and prevent ankle sprains. Discover causes, symptoms, recovery time, and treatment options from Unpain Clinic’s experts in Edmonton.
Key takeaways
- An ankle sprain is rarely just a sprain. The ligament can heal while the ankle's stability, balance, and coordination do not.
- Pain drops quickly in the first couple of weeks for most people, but a meaningful number still have pain or a sense of instability a year later.
- The single biggest risk factor for spraining your ankle is having sprained it before.
- Early, guided movement beats long rest. Functional treatment, meaning gentle movement, support, and exercise, tends to get you back faster than immobilizing the ankle.
- Balance and strength training is the part most people skip, and it is what lowers your chance of the next sprain.

We have all heard it: "it is just a sprained ankle." If you have ever limped for weeks after one, you know it is rarely just anything. An ankle sprain can swell, bruise, and throb for days, and it can leave every step feeling uncertain. The ligament often heals on its own, but the balance and control that protect the ankle do not come back by themselves, and that is the part worth getting right. For how we think about foot and ankle problems in general, our podcast on fixing chronic foot pain is a good listen.
What exactly is an ankle sprain?
An ankle sprain happens when the ligaments, the tough bands that connect bone to bone and stabilize the joint, get stretched or torn beyond their normal range. Knowing which ligaments are involved helps explain why some sprains bounce back quickly and others drag on.
Most sprains happen on the outside of the ankle when the foot rolls inward. This lateral sprain usually affects the anterior talofibular ligament, and sometimes the calcaneofibular ligament next to it. These are the classic rolled-ankle injuries.
A high ankle sprain is a different animal. It affects the ligaments that hold the two shin bones together, above the ankle joint, and it tends to heal more slowly. High ankle sprains are often mistaken for an ordinary sprain, which is one reason they get undertreated. If your sprain feels unusually stubborn, it is worth having someone check which structures are actually involved.
Why do the pain and swelling linger?
The pain and swelling linger because most people stop too soon. They rest until it feels better, then return to normal life, and the ankle never gets the retraining it needs. The ligament heals, but the joint's stability, balance, and coordination, the sense your body uses to keep the ankle steady, stay behind.
The research backs this up. A systematic review of the recovery course after ankle sprains found that while pain drops quickly in the first two weeks, a meaningful share of people still had pain a year later, and up to about a third had at least one repeat sprain within three years. In other words, feeling better is not the same as being fully recovered.
This is where the sprain and repeat cycle begins. When balance and control are not restored, the ankle stays vulnerable, so it rolls again, and the pattern repeats. That is why the single biggest risk factor for spraining your ankle is having already sprained it. When the ankle keeps giving way, it is often a sign of what is called chronic ankle instability, which usually means the strength and coordination were never fully rebuilt.
How long does an ankle sprain take to heal?
Recovery time depends on how much the ligament was damaged, and just as much on what you do during that time. As a general guide, a mild Grade 1 sprain, where the ligament is stretched, often settles in about two to three weeks with early movement. A moderate Grade 2 sprain, a partial tear, often takes four to six weeks before full activity. A severe Grade 3 sprain, a complete tear, can take eight to twelve weeks or longer. A high ankle sprain tends to take close to twice as long as a standard sprain.
Those timelines are ranges, not promises, and individual recovery varies. What matters more is the approach. A Cochrane review of ankle sprain treatment found that functional treatment, meaning early gentle movement with support such as a brace, got people back to work and sport faster and with less lingering swelling than immobilizing the ankle in a cast.
The takeaway is simple. Starting safe movement early, rather than resting until all the pain is gone, tends to speed up recovery rather than risk it.
How does Unpain Clinic treat ankle sprains?
We treat ankle sprains by rebuilding movement, balance, and confidence, not just calming the pain. It starts with a 60 minute, one-on-one assessment that looks at the whole chain, from your hips to your foot, because a stiff or weak link above the ankle often keeps it vulnerable. A common pattern we see is limited ankle dorsiflexion, weak hip stabilizers, and poor balance on the injured side, all of which can be retrained.
Our physiotherapy and chiropractic care use gentle joint mobilizations to restore normal ankle motion, especially the ability to bend the foot upward, which is often lost after a sprain. Restoring that motion early tends to reduce pain and stiffness faster, and it is the same ligament-focused rehab we describe in our guide to physiotherapy for ligament injuries.
Once the acute phase has settled, focused shockwave therapy can help with lingering tenderness or stiffness in the surrounding soft tissue. Shockwave has a solid track record for tendon and soft-tissue pain, with a 2024 review of 45 trials finding it reduced pain across several tendon problems. We use it for the stubborn, post-acute part of recovery rather than in the first few days, as covered in our guide to shockwave therapy for sports injuries. Where swelling or pain sensitivity is slowing progress, we may add EMTT and NESA neuromodulation, gentle therapies that support healing and help calm an overactive pain response.
The cornerstone, though, is progressive exercise and balance training. Retraining the ankle's strength and coordination is what protects it long term. A meta-analysis of balance and proprioceptive training found it lowered the rate of ankle sprains by about a third, with the biggest benefit for people who had sprained an ankle before. A brace or kinesiology tape can add temporary stability while you rebuild that internal control.
Here is what a typical ankle sprain plan looks like:
- Assess the whole chain. We check the ankle, but also your dorsiflexion, hip strength, and balance, to find what is keeping the ankle vulnerable.
- Restore motion. Hands-on mobilization brings back normal ankle movement, especially the ability to bend the foot upward.
- Calm stubborn tissue. For lingering tenderness after the acute phase, we may use shockwave, EMTT, or neuromodulation.
- Rebuild strength and balance. Progressive loading and coordination drills retrain the system that protects the ankle. This is the step that prevents the next sprain.
- Support the return to activity. Bracing or taping adds stability while you build control, then we progress you back toward your sport or daily demands.
- Reassess and progress. We track how the ankle responds and advance the plan so you keep improving.
What can you safely do at home right now?
Even before formal rehab, there is a lot you can safely do, as long as you stay out of sharp pain. Ease off or scale back if pain or swelling increases, and check with a clinician when in doubt.
- Early phase, days one to five. Protect the ankle with a brace or wrap, elevate and gently compress to manage swelling, and keep it moving with ankle circles or writing the alphabet with your toes. Short walks are fine if pain allows, and total rest is not the goal.
- Middle phase, days five to fourteen. Add light resistance work with a band in all four directions, start double-leg and then single-leg heel raises, and practise standing on one foot to rebuild balance.
- Advanced phase, week three and beyond. Progress to hopping, direction changes, and agility drills, and keep balance work in your routine even once you feel recovered, since that is what holds the gains.
If you play sport and want to protect the rest of the leg too, our guide to preventing ACL and MCL injuries and our guide to injury prevention go further. And if pain sits along the outer ankle and foot, our guide to peroneal tendon pain may be relevant.
Frequently asked questions
How do I know what grade of sprain I have?
Grade 1 is a mild stretch, Grade 2 is a partial tear, and Grade 3 is a full tear of the ligament. The grade affects how long recovery takes and how much support you need early on. A physiotherapist can assess the ligament's stability and guide the right level of care, since grading by feel alone is unreliable.
Should I walk on a sprained ankle?
Usually yes, if it is tolerable. Early, gentle weight-bearing encourages healing and is part of the functional approach the research supports. The key is to stay within comfortable limits and avoid forcing movement through sharp pain or a heavy limp. If you cannot put weight on it at all, get it assessed.
Why does my ankle keep giving out?
An ankle that repeatedly gives way often points to chronic ankle instability. It usually means the balance, strength, or coordination was not fully restored after a previous sprain, so the joint stays vulnerable. The good news is that targeted balance and strength training can rebuild that control and reduce the giving-way.
Do I need an X-ray or MRI?
Not always. Most ankle sprains are diagnosed by a clinical exam rather than imaging. An X-ray or MRI is mainly considered when there is severe pain, an obvious deformity, or an inability to bear weight, which can suggest a fracture or a more serious injury. A clinician can decide whether imaging is worth it in your case.
Can I prevent future sprains?
Yes, to a meaningful degree. Balance and proprioceptive training is the most effective step, and it helps most for people who have sprained an ankle before. Supportive footwear helps, and bracing during high-risk sport can add protection. Consistency with the balance work is what makes the difference.
“I took my son to Dr.Lacina. We had been seeing several other health professionals throughout the summer and Dr. Lacina performed the most thorough assessment of any of them! She treated him for his back pain via shockwave therapy and chiropractic. She also identified that he may benefit from shockwave to his knee and ankle by listening intently to him during the assessment and treated him as part of the same appointment. Although he ended up having a more major injury than initially suspected, she was amazing to deal with and has followed up with me personally several times and continued to offer additional advice. She is highly educated and knowledgeable in her field. I recommend Dr. Lacina at the Unpain Clinic for any sort of ailment you may have currently or if you are suffering from past injuries.”- Rhelda Baschuk
