Inward ankle sprains are one of the most common injuries in almost every sport, including basketball, soccer, and football. Not usually as serious as a fracture, but definitely the kind of injury you want to recover from properly before jumping back into training.
So, how long does a sprained ankle take to heal? A mild ankle sprain recovery time is usually around 2 to 3 weeks. More severe ligament injuries can take up to 2 to 3 months. Rehab really depends if it was a twist or a tear, how much swelling, and instability.
Here we’ll explain the different grades of ankle sprains, and the healing process in each case. What can you do to help your recovery move faster and safer? Let’s get started.
What is a Sprained Ankle?
The most common type of ankle sprain happens when the foot twists inward too far. This overstretches the ankle ligaments and can cause anything from a mild stretch to a partial or complete tear.
On the outside of the ankle, there are three main ligaments that help keep the joint stable:
- Anterior Talofibular Ligament (ATFL): This is the ligament most commonly injured in ankle sprains. It sits toward the front of the ankle and takes most of the stress when the foot rolls inward.
- Calcaneofibular Ligament (CFL): This ligament runs along the side of the ankle, connecting the fibula to the heel bone. It’s often involved in moderate ankle sprains, especially when the ankle rolls harder sideways.
- Posterior Talofibular Ligament (PTFL): This sits deeper and farther back near the heel. It’s the strongest of the three ligaments and usually only gets injured in severe ankle sprains.
Most ankle sprains happen during movements like landing awkwardly from a jump, cutting side to side, or stepping unevenly while running. That inward roll overstretches the ATFL first, which is why mild ankle sprain recovery time is usually shorter when only this ligament is involved.
But it all depends on how hard the ankle twists. More severe sprains happen when the ankle rolls inward with greater force and sideways tilt. In those cases, both the ATFL and CFL can tear together. When that happens, recovery can take anywhere from 1 to 3 months, depending on the amount of ligament injury, swelling, and instability.
The one ligament that rarely gets injured is the PTFL, because it takes a much stronger twisting force to reach it. Usually, that only happens during high-impact sports injuries or major ankle trauma.
Types of Ankle Sprain: How Much They Take to Heal?
The short answer is this: A mild sprain may settle within a couple of weeks, while a more serious ligament injury can take several months to fully recover.
Let’s break down the different grades of ankle sprains and what recovery usually looks like for each one.
Grade 1: Mild Ankle Sprain Takes Within 2 to 3 Weeks To Heal
A Grade 1 sprain is the mildest type of ankle injury. The ligament overstretches, but there’s no major tearing. Mild ankle sprain recovery time is usually around 2 to 3 weeks.
You’ll typically feel mild tenderness, light swelling, and some stiffness around the ankle. The joint still feels stable, and most people can walk with only minor discomfort.
With proper rest, icing, compression, and gentle mobility work, recovery tends to move fairly quickly.
Grade 2: Moderate Ankle Sprain Takes Within 3 to 6 Weeks To Heal
A Grade 2 ankle sprain happens when the inward roll goes further and partially tears the ligament. Recovery usually takes between 3 to 6 weeks, depending on the amount of ligament injury recovery you need.
Pain and swelling are more noticeable in a moderate ankle sprain. Bruising may also appear over the next couple of days. Walking often becomes difficult. Many athletes limp or struggle to fully load the foot. The ankle can also feel weak or unstable during movement.
Recovery usually includes rest, bracing, and progressive rehab exercises to rebuild strength, balance, and ankle stability.
Grade 3: Severe Ankle Sprain May Take Within 2 to 3 Months To Heal
A Grade 3 sprain is the most severe type of ankle sprain. The ligament tears completely, and the ankle often feels unstable or gives out when standing or walking. The severe ankle sprain healing process can take anywhere from 2 to 3 months.
This is usually the type of sprain where swelling and bruising become much more aggressive. In many cases, the ankle turns dark purple or black around the outside and foot within the first 24 to 48 hours.
Many athletes need temporary immobilization, crutches, or a walking boot during early recovery. Some severe ligament injuries may even require surgery, especially if instability continues after rehab.
The later stages of recovery focus heavily on rebuilding strength, balance, and coordination to help prevent
Symptoms & Healing Stages?
Right after an ankle sprain, regardless of the grade, the first symptoms are usually pain and soreness around the ankle. Some athletes also feel a small “pop” or crack during the twist, which can happen when the ligament stretches or tears.
In more severe ankle sprains, bruising may appear within a few hours and continue spreading over the next couple of days. That black or purple discoloration can look alarming, but it’s a common part of the ligament injury recovery process.
Mild sprains may only swell slightly, while severe tears can leave the ankle noticeably swollen, stiff, and unstable. If pain, swelling, or instability feel significant, it’s a good idea to see a doctor or physiotherapist for a sprain evaluation.
From there, the severe ankle sprain healing process usually moves through three main stages: inflammation, repair, and remodeling.
How to Heal Faster
What should you do immediately after an ankle sprain? In most cases, the first step is RICE: Rest, Ice, Compression, and Elevation. That early phase is important for controlling swelling and protecting the injured ligament.
In short, here’s how recovery usually starts depending on the grade of the sprain:
- Grade 1 ankle sprain: usually needs about 1 to 2 days of icing and relative rest.
- Grade 2 ankle sprain: often needs around 4 to 5 days of reduced activity, icing, and support.
- Grade 3 ankle sprain: may require 1 to 2 weeks of immobilization, bracing, or limited weight bearing before progressing rehab.
If you’re wearing compression sleeves, braces, or a walking boot, don’t rush out of them too early. We know they’re uncomfortable, but they help protect the ankle during the early ligament injury recovery stage.
After an ankle sprain, the body immediately enters an inflammation phase. That’s part of the healing process, not something you can skip. One of the most common mistakes we see athletes make is trying to “walk it off” too soon, or thinking massage alone will fix the injury after a day or two.
Of course active recovery is important, but that comes when it’s time to rebuild mobility, balance, and strength.
During those first few days, rest and swelling are the most important for recovery. After that, comes the rehab.
Physiotherapy & Recovery Training
These are some of the recovery exercises and stretches our physical therapists use during ankle sprain rehab. But there’s a couple important things before starting:
- Do a light warm up before stretching or rehab exercises. Your PT can guide you on what’s appropriate for your injury stage.
- Never force stretches into pain. Some discomfort and stiffness are normal during ligament injury recovery, but sharp pain is not.
Early Recovery Phase
The early phase of ankle sprain rehab focuses on restoring gentle mobility and reducing stiffness. These are slow, controlled exercises. This is not the stage to rush.
Ankle circles:
- Sit comfortably in a chair with your injured foot slightly elevated.
- Slowly rotate the ankle in small controlled circles.
- Complete 10 circles clockwise, then 10 counterclockwise.
Toe stretches:
- Sit with your foot flat on the floor.
- Lift and spread your toes as comfortably as possible.
- Hold for 5 seconds, then relax. Repeat 10 times.
Calf stretches:
- Stand facing a wall with your hands supported against it.
- Step the uninjured foot forward while keeping the injured foot back and both heels on the ground.
- Lean forward gently until you feel a stretch through the calf.
- Hold for 20–30 seconds and repeat 2–3 times.
Mid Recovery Phase
As swelling decreases and movement improves, rehab starts incorporating strengthening exercises and controlled loading. This stage helps the ankle regain support and stability.
Towel curls:
- Sit with your foot flat on the ground and a towel placed in front of you.
- Use your toes to scrunch the towel toward you.
- Repeat 10–15 times.
Resistance band foot pushes:
- Sit on the floor or in a chair and loop a resistance band around the ball of your foot.
- Push forward against the band in a controlled motion, then slowly return.
- Repeat 10–15 times.
Plantar fascia stretches:
- Sit with the injured foot resting over your opposite knee.
- Gently pull your toes back toward your shin until you feel a stretch along the bottom of the foot.
- Hold for 15–20 seconds and repeat 3–5 times.
Late Recovery Phase
The final stage of ankle sprain recovery focuses on rebuilding strength, balance, and coordination to help prevent re-sprains. For athletes returning to sports like basketball, soccer, football, or running, physical therapy at this stage often includes:
- Balance drills like single-leg stands or wobble boards
- Agility and proprioception training like light hops and side steps
- Sport-specific movement progression
Heel raises:
- Stand near a wall or sturdy chair for support.
- Slowly rise onto your tiptoes, hold for 2–3 seconds, then lower back down under control.
- Repeat 10–15 times.
Standing foot presses:
- Stand next to a wall or chair for balance.
- Shift weight gently onto the injured foot and press into the ground.
- Hold for 5–10 seconds before relaxing.
- Repeat 10 times, increasing duration gradually as strength improves.
What Should I Do If I Sprain My Ankle?
When you sprain your ankle, you usually know right away, but the real question is: how severe is it? If the pain, swelling, bruising, or instability feel significant, it’s a good idea to see a doctor or physiotherapist for a sprain evaluation as soon as possible.
But not every ankle sprain is automatically a severe tear. Sometimes it’s just a mild tweak with soreness and light swelling. In those cases, starting with a few days of rest, ice, compression, and reduced activity may be enough while you monitor how the ankle responds.
Regardless of the grade, you want to avoid overloading the ankle early on. Taking a short break from training and sports activities gives the ligament injury recovery process time to settle before you start rebuilding strength and mobility.
Many athletes re-sprain the same ankle by returning to activity too quickly, so it’s important not to rush recovery.
