A mild sprained ankle typically hurts for 1 to 3 weeks, while more severe sprains can cause pain lasting several weeks to several months. The timeline depends almost entirely on how much damage the ligament sustained, whether it was stretched, partially torn, or completely torn.
Most people searching this question are a few days or weeks into recovery and wondering if what they’re feeling is normal. Here’s what to expect at each level of severity, what the healing process actually looks like inside your ankle, and the signs that something more serious may be going on.
Pain Timelines by Sprain Severity
Ankle sprains are graded on a 1-to-3 scale based on ligament damage. Each grade comes with a different pain window.
- Grade 1 (stretched ligament, no tear): Pain and swelling usually resolve within 1 to 3 weeks. You can often walk on it right away, though it will be uncomfortable. The American Academy of Family Physicians puts mild sprain recovery at 1 to 2 weeks.
- Grade 2 (partial tear): Expect pain for 3 to 6 weeks. Walking is harder in the first week, and the joint may feel unstable. Swelling and bruising are more noticeable.
- Grade 3 (complete tear): Recovery takes several months. Pain can linger for 6 to 8 weeks or longer, and full function may not return for 3 to 4 months depending on treatment.
There’s also a less common type called a high ankle sprain, which injures the ligament connecting the two lower leg bones above the ankle joint rather than the ones on the outside. These are significantly slower to heal, averaging 8 to 12 weeks of recovery even with proper care.
What’s Happening Inside Your Ankle
Understanding the biology helps explain why pain follows the pattern it does. Ligament healing happens in three overlapping phases, and each one feels different.
The first is the inflammatory phase, which peaks between 3 and 72 hours after the injury. This is when your ankle is at its most swollen, warm, and painful. The swelling itself puts pressure on surrounding nerves, which is a big part of why it hurts so much early on. This phase lasts roughly 1 to 3 days.
Next comes the repair phase, when your body starts laying down new collagen to patch the damaged ligament. This ramps up quickly and peaks around 2 to 3 weeks. During this window, pain gradually decreases but the area is still fragile. You’ll notice it hurts less at rest but still flares with certain movements.
The final phase, remodeling, is the longest. It starts around weeks 2 to 3 and can continue for up to 40 weeks, sometimes close to a year. During remodeling, the new tissue is reorganizing and strengthening. You probably won’t feel sharp pain during this phase, but you may notice stiffness, mild soreness after activity, or a sense that the ankle isn’t quite “right” yet. That’s normal. The ligament is still maturing even after the pain is gone.
Why Resting Too Long Can Backfire
The old advice was to stay off a sprained ankle as long as possible. Current guidelines from the British Journal of Sports Medicine recommend a different approach: protect the ankle for the first 1 to 3 days by limiting movement, then start gradually loading it with movement and exercise as soon as symptoms allow.
A randomized trial published in The BMJ found that people who started gentle exercises early after a sprain regained function significantly faster than those who relied on standard rest and bracing, with measurable differences showing up as early as the first week. The exercise group was also more physically active during recovery, taking more steps and spending more time walking. Interestingly, the two groups reported similar levels of pain at rest and during activity, meaning early movement didn’t make the pain worse. It just got people back to normal sooner.
Pain-free light cardio, like cycling or swimming, a few days after injury can also boost blood flow to the healing tissue without stressing the ligament. The key is that movement should be guided by your symptoms. If an activity causes sharp pain, back off. Mild discomfort during rehab exercises is generally expected.
Pain That Lasts Longer Than Expected
If your ankle still hurts after the timelines above, or if the pain initially improved and then plateaued, a few things could be going on.
The most common culprit is chronic ankle instability, a condition where the ankle repeatedly feels like it might “give way” during everyday activities like walking on uneven ground. This is diagnosed when instability persists for more than 6 months after the original sprain. It develops because the damaged ligament healed in a loosened state, or because the nerves that help your brain sense the ankle’s position were disrupted. Rehab exercises that focus on balance and coordination are the primary treatment.
Reinjury is another reason pain drags on. About 1 in 4 ankle sprains recur, and most of those repeat injuries happen between 2 and 12 months after the first one. If you returned to sports or intense activity before the ligament fully healed, a re-sprain can restart the clock on recovery without you even realizing it was a new injury.
There’s also the possibility that the original injury was worse than you thought. A sprain that was treated as a grade 1 may actually have been a grade 2, or there may be a small fracture involved.
Signs It Might Not Be Just a Sprain
Some ankle injuries that feel like sprains are actually fractures. Emergency departments use a screening tool called the Ottawa Ankle Rules to decide whether an X-ray is needed. You likely need imaging if you have tenderness when pressing on the bony bumps on either side of your ankle (the back edge or tip of those protruding bones), tenderness at the base of the small toe bone on the outer edge of your foot, or you couldn’t take four steps right after the injury.
If your pain is severe enough that you truly cannot put weight on the ankle at all after the first 48 hours, or if the ankle looks visibly deformed, those are reasons to get it evaluated promptly rather than waiting it out.
Over-the-Counter Pain Relief
Both ibuprofen and acetaminophen work about equally well for sprain pain. A study of 260 patients with mild to moderate sprains found no difference between the two in pain relief, walking ability, time to resume normal activity, or swelling. Neither drug was superior on any measure.
One nuance worth knowing: some sports medicine experts now advise caution with anti-inflammatory drugs like ibuprofen in the first few days, since the inflammatory response is part of how your body initiates healing. Acetaminophen manages pain without suppressing inflammation, which may make it a better choice in the acute phase. After the first few days, either option is reasonable for managing discomfort during rehab.
A Realistic Recovery Checklist
Rather than watching the calendar, tracking what you can do gives you a better sense of where you are in healing:
- Days 1 to 3: Pain and swelling at their worst. Walking is difficult or impossible with a severe sprain.
- Week 1: Swelling starts to decrease. You can begin gentle range-of-motion movements for mild sprains.
- Weeks 2 to 3: Most grade 1 sprains feel significantly better. You can walk normally and start balance exercises.
- Weeks 4 to 6: Grade 2 sprains are approaching full recovery. Light jogging may be comfortable.
- Months 2 to 4: Grade 3 and high ankle sprains are still healing. Full return to cutting and pivoting sports comes last.
Some lingering stiffness or mild aching after long days on your feet can persist for weeks beyond when you’d consider yourself “recovered.” That’s the remodeling phase doing its work, and it doesn’t mean you’ve reinjured anything. Consistent balance and strengthening exercises during this period are the single best thing you can do to protect against re-spraining the ankle down the road.
