A rolled ankle is one of the most common injuries there is, whether it happens on a trail, a curb, or the last step of a staircase. Most mild to moderate sprains heal well with simple home care, but the first two days matter a lot. This guide walks through exactly what to do, what to avoid, and how to recognize the signs that mean you should get it checked by a professional.
What a sprain actually is
A sprain is a stretch or tear of the ligaments, the tough bands that connect bone to bone and hold the ankle joint together. Most ankle sprains are “inversion” injuries, where the foot rolls inward and the ligaments on the outside of the ankle take the strain. Sprains are graded by severity:
- Grade 1 (mild): ligaments overstretched, minor swelling, you can still put weight on it.
- Grade 2 (moderate): partial tear, noticeable swelling and bruising, walking is painful.
- Grade 3 (severe): complete tear, significant swelling, the joint feels unstable, bearing weight is very difficult.
Grade 1 and many grade 2 sprains can be managed at home. Grade 3 sprains, and anything you are unsure about, should be evaluated by a doctor.
The first 48 hours: the RICE method
RICE stands for Rest, Ice, Compression, and Elevation. It is the standard first-aid approach for a fresh sprain and it works best when you start right away.
Rest
Stop the activity immediately and get the weight off the ankle. Continuing to walk or “shake it off” can turn a mild sprain into a worse one. For the first day or two, use crutches or lean on something if walking is painful. Complete immobility is not the goal, but hard use is.
Ice
Apply a cold pack wrapped in a thin towel for 15 to 20 minutes every 2 to 3 hours while you are awake, for the first 48 hours. Never put ice directly on skin, and do not fall asleep with it on. Cold reduces swelling and dulls pain. If you have hiked or exercised, the same cooling approach that helps sore muscles after hiking applies here, though a sprain needs more caution.
Compression
Wrap the ankle with an elastic bandage, starting at the toes and working up past the ankle, overlapping each layer by about half. It should feel snug but not tight enough to cause numbness, tingling, or increased pain. Loosen it if your toes turn pale or cold. Remove it at night.
Elevation
Prop the ankle above the level of your heart whenever you can, especially in the first 48 hours. Lying down with the leg on a stack of pillows is more effective than sitting with the foot on a stool.
Managing pain and swelling
Over-the-counter pain relievers such as ibuprofen or naproxen reduce both pain and inflammation. Acetaminophen helps with pain but not swelling. Follow the dosing on the label and check with a pharmacist if you take other medications or have stomach, kidney, or liver concerns.
Avoid heat, alcohol, vigorous massage, and hot baths for the first 48 to 72 hours. All of them increase blood flow and can make swelling worse early on. Heat can be useful later, once the swelling has settled, to ease stiffness.
Days 3 to 14: gentle movement and recovery
Once the sharp pain and worst swelling ease, usually after a few days, total rest is no longer helpful. Gentle, pain-free movement speeds healing and prevents stiffness.
- Ankle alphabet: trace each letter of the alphabet in the air with your big toe, moving only the ankle.
- Range-of-motion circles: slow ankle rotations in both directions, several times a day.
- Weight bearing: gradually put more weight on the ankle as it tolerates, progressing from standing to walking normally.
- Towel stretch: sit with the leg straight, loop a towel around the ball of the foot, and gently pull the toes toward you to stretch the calf.
- Balance work: once walking is comfortable, practice standing on the injured leg for 20 to 30 seconds to rebuild stability.
Stop any exercise that causes sharp pain. Mild discomfort that fades quickly is fine.
What not to do
- Do not walk long distances or return to sport before you can move and bear weight without a limp.
- Do not apply heat or massage in the first 2 to 3 days.
- Do not wrap the bandage so tightly that your foot goes numb.
- Do not ignore it. Poorly rehabbed sprains often become chronically weak and re-injure easily.
When to see a doctor
Seek medical care promptly if any of the following apply:
- You cannot put any weight on the foot, or cannot take four steps, even right after the injury.
- There is bone tenderness directly over the ankle bones or the top of the foot.
- The ankle looks deformed or out of place.
- You heard or felt a distinct “pop” at the moment of injury.
- Numbness, tingling, or the foot turning cold or blue.
- Swelling and pain are severe or are getting worse after 2 to 3 days of proper home care.
- The ankle has not meaningfully improved after a week, or still feels unstable after two weeks.
These can indicate a fracture, a complete ligament tear, or nerve involvement that needs imaging and professional treatment. When in doubt, get it checked. The same “know when to escalate” judgment applies to other outdoor injuries, such as a bad reaction to a bee sting or a deep splinter you cannot remove.
Preventing the next sprain
Ankles that have been sprained once are more likely to be sprained again, so rehab fully before returning to activity. Wear supportive footwear for the terrain, strengthen the muscles around the ankle with balance and resistance-band work, warm up before sport, and consider a brace or taping for high-risk activities during the first few months after an injury. If you hike or backpack, our guide on preparing your feet for the trail covers footwear fit, which also reduces rolling risk.
Frequently asked questions
How long does a sprained ankle take to heal?
A mild grade 1 sprain often feels much better within one to two weeks. Moderate grade 2 sprains take three to six weeks. Severe grade 3 sprains can take several months and sometimes need physical therapy or, rarely, surgery.
Should I walk on a sprained ankle or stay off it?
Stay off it for the first day or two if walking is painful. After that, gentle weight bearing and movement actually speed recovery. The goal is to progress from rest to normal walking as pain allows, not to immobilize it for weeks.
Is heat or ice better for a sprained ankle?
Ice for the first 48 to 72 hours to control swelling. Heat can help afterward to loosen stiffness, but using it too early increases blood flow and can make swelling worse.
How do I know if it is sprained or broken?
You cannot be certain without an X-ray, but signs pointing to a possible fracture include being unable to bear any weight or take four steps, bone tenderness directly on the ankle bones, an obvious deformity, or a loud pop at the time of injury. If any of these are present, see a doctor.
Can I exercise with a sprained ankle?
Not hard exercise or sport until you can walk without a limp and move the ankle through its full range without sharp pain. Gentle range-of-motion and balance exercises, however, are encouraged after the first few days.
Why does my old ankle sprain keep coming back?
Ligaments that have been stretched or torn can heal loose, and the stabilizing muscles often stay weak if the ankle was never properly rehabbed. Balance training, resistance-band strengthening, and supportive footwear reduce the chance of re-injury.
