The Best Home Treatment for a Sprained Ankle

A sprained ankle is one of the most common injuries to the lower body, occurring at a frequency of 600-700 per 100,000 people (1). This number increases with participation in sports, and accounts for nearly 22% of all emergency room visits in athletes (2). The most common ankle sprain is a lateral ankle sprain. This makes up nearly 85% of all ankle injuries, with inversion or rolling of the foot inward being the most common mechanism of injury (3).

Once an ankle sprain has occurred, symptoms may remain for a long time! In as many 30% in the general population symptoms can be come chronic in nature (4). Not only can symptoms become chronic but once you sustain an ankle sprain, you’re at an increased risk for a second sprain. A history of ankle sprain is the single best predictor of a sustaining a future ankle sprain (5). This is one reason why it is important to treat the first one ankle sprain properly to avoid it becoming an issue down the road.

What is a Sprained Ankle?

An ankle sprain is when you roll the ankle sideways and stretch or tear the ligaments of the ankle. Most people have experienced this at sometime in your life such as when stepping off a curb, stepping in a whole, or landing on someone else’s foot in a sporting event.

An example for an everyday person is walking and not paying attention, when you step on a rock. Your foot rolls inward, you quickly pick up your foot but it’s too late. The outside of the foot and ankle is now painful and depending on the severity, can be difficult to put weight on it.

Most of the time you try to walk it off and take a few steps to see if the pain decreases. Fortunately, most of the time it does with just a little residual soreness. But what if it doesn’t? What if that pain lingers and remains weeks after? We’re here to help.

Severity of Ankle Sprain Grades

Ankle sprains come in 3 different grades depending on the amount of injury and ligament stretch. See if you can identify the ligaments affected with each grade of ankle sprain.

Grade 1 Ankle Sprain (Mild):

Mild stretching of or microscopic tearing of the ligament on the outside ankle – ATFL ligament is most commonly affected
Mild swelling and discomfort with weight bearing
Usually heals quickly (2-3 weeks) with ice and rest

Grade 2 Ankle Sprain (Moderate):

Mild/mod swelling with increased pain during weight bearing
May walk with a limp
Partial tearing of the ligaments on the outside of the ankle – ATFL and CFL ligaments most commonly impacted
May experience increased laxity during movement and feeling of giving out early on
Takes a little bit longer to heal with a general time frame of 4-6 weeks
May need to wear a CAM boot for walking

Grade 3 Ankle Sprain (Severe):

Considerable tenderness, swelling, bruising, and pain
May not be able to bear weight for the first week or two and may need to use crutches
Moderate/complete tearing of the ligaments on the outside of the ankle – ATFL, CFL, and PTFL are all impacted
Much longer time to heal with a general timeline of 6-12 weeks depending on several factors
Greatest lost of balance and stability when standing

Most ankle injuries do not require surgery and heal with conservative treatment and time. Grade 1 ankle sprains can usually be treated at home with minimal intervention. Grade 2-3 often require more a involved recovery and may benefit from seeing a medical professional. Often times a quality ankle brace can get you through the painful state and you can be on your way. See our post on the Best Ankle Braces found on Amazon here.

When to see a Doctor after a Sprained Ankle?

Most of the time mild and moderate ankle sprains do not require a visit to your doctor. However here are some instances that make warrant a visit to a physician.

Inability to bear weight immediately after the injury and within 48 hours
Misalignment of the bones of the lower leg
Bleeding or immediate change of color with loss of pulse
Numbness and tingling that is getting worse
Severe, unimaginable pain when touching the bones of the lower leg

When you do sprain your ankle it is paramount that you continue to try and walk on it and put weight on it as much as possible. Even though initially it will likely hurt it does speed up recovery and help determine the severity of the injury. If you still cannot walk without pain and do not want to spend the $800 for a doctor visit, negative x-rays, and an overpriced boot; then you should order a CAM boot and wear it for 2 weeks and re-assess.

How to Treat an Ankle Sprain at Home

The treatment for ankle sprains at home is divided into 3 distinct phases. The time needed in each phase is dependent on many different factors including the severity of the sprain, job duties at work, and the prior history of injuries. Time frames are listed for generalization and may be different for each individual person. As always please consult your physician before starting any exercise program.

Ankle Sprain Rehab Phase 1 – Rest and Healing Phase (1-3 weeks)

During this phase of treatment the primary goal is to allow for healing to occur. You want to control the swelling, control the pain, and try to increase weight bearing as your pain decreases. During this time is it important to not do too much, yet we don’t want it to completely stiffen up either.

This is the time for the R.I.C.E Protocol – Rest, Ice, Compression, and Elevation
The use of an ankle brace may help to begin increasing bearing weight in the ankle – soft sided bracing has better outcomes as opposed to a hard casts for mild and moderate sprains (6)
The use of manual therapy and massage to improve range of motion and pain may be effective in the short term (7)
Begin gentle ROM exercises such as ankle pumps, foot ABC’s, and towel scrunches
If you are limping it is recommended that you use crutches until you can bear weight pain free
Use a stationary bike to maintain your current fitness levels

Ankle Sprain Rehab Phase 2 – Increase Movement and Strength (2-6 weeks)

During this phase of treatment the pain and swelling should be starting to decrease and it is time to focus improving the motion and strength in the ankle. The treatment and activity in this phase should be relatively pain free, with mild discomfort at end range stretching. If there is any sharp pain or increase in swelling, back it off slightly.

Begin Theraband exercises for ankle strength
Begin calf raise progression
Begin stretching program and self ankle joint mobility
Should be off the crutches at some point in this time periods but may still need a brace for pain free normal walking or sports participation

Ankle Sprain Rehab Phase 3 – Improve Balance and return to Dynamic Activity (6-12 weeks)

In this phase the emphasis is returning to normal with both static and dynamic balance, and return to dynamic activity which includes running, jumping, and lateral movement. Even if you are not an athlete, this phase is still extremely important to develop the foot awareness and balance to avoid Chronic Ankle Instability and have problems long term.

Improve single leg balance with eyes open and more importantly eyes closed
Begin a plyometric program for load progression
Beginning a jogging program starting at much less time and distances than you were at before the injury
May still need a lace up brace as you return to playing competitive sports

Now is the time in rehab that you can start to incorporate normal activities such as walking, running, and jumping. For the weekend warriors and gym rats, its time to start preparing for your return to sport activities.

Functional Activities:

Box jumps
Scissor jumps
Bounding

Bosu Ball For Ankle Sprains

One of the best ways to improve ankle instability and strength after an ankle sprain is to use a bosu balance trainer.
