How Long Does a Sprained Ankle Take to Heal?

Quick Answer

A mild ankle sprain (Grade 1) heals in 1–3 weeks. A moderate sprain (Grade 2) takes 3–6 weeks. A severe sprain (Grade 3) with complete ligament tear takes 2–6 months and may require surgery. Most sprains heal with rest and physical therapy, but proper rehab is essential to prevent chronic ankle instability.

Healing Time by Grade

Grade	Injury	Symptoms	Recovery
Grade 1 (Mild)	Stretched ligament, micro-tears	Mild pain, slight swelling, can walk	1–3 weeks
Grade 2 (Moderate)	Partial ligament tear	Moderate pain/swelling, bruising, difficulty walking	3–6 weeks
Grade 3 (Severe)	Complete ligament tear	Severe pain/swelling, instability, can't bear weight	2–6 months

Recovery Timeline

Grade 1 (Mild Sprain)

• Day 1–3: Pain and swelling at their worst
• Day 3–7: Swelling decreases, pain reduces with movement
• Week 1–2: Walking normally, beginning light exercises
• Week 2–3: Return to most activities

Grade 2 (Moderate Sprain)

• Day 1–5: Significant swelling, bruising, painful to walk
• Week 1–2: Swelling decreases, may use a brace or wrap
• Week 2–4: Begin physical therapy exercises
• Week 4–6: Gradual return to activity
• Week 6–8: Return to sports with ankle brace

Grade 3 (Severe Sprain)

• Week 1–2: Immobilization (walking boot or cast)
• Week 2–6: Protected movement, begin gentle rehab
• Week 6–12: Physical therapy, progressive strengthening
• Month 3–6: Gradual return to full activity
• Surgery may be needed if the ankle remains unstable

Immediate Treatment: R.I.C.E. (First 48–72 Hours)

• Rest — stay off the ankle, use crutches if needed
• Ice — 20 minutes on, 40 minutes off, several times per day
• Compression — elastic bandage to reduce swelling (not too tight)
• Elevation — keep the ankle above heart level as much as possible

Take ibuprofen or naproxen for pain and to reduce inflammation.

Physical Therapy Exercises (After Initial Healing)

Rehab exercises are critical to prevent re-injury:

Range of motion — ankle circles, alphabet tracing with toes

Strengthening — resistance band exercises in all directions, calf raises

Balance training — single-leg standing, wobble board exercises

Functional training — walking, jogging, cutting movements (progressive)

Skipping rehab is the main reason for chronic ankle problems. About 40% of ankle sprains lead to chronic instability when not properly rehabilitated.

When to See a Doctor

• Can't bear any weight on the ankle
• Severe swelling that doesn't improve in 48 hours
• Numbness or tingling in the foot
• Visible deformity (possible fracture)
• Pain directly over the ankle bone (not just the soft tissue)
• No improvement after 5–7 days
• Repeated sprains of the same ankle

Sprain vs. Fracture

Feature	Sprain	Fracture
Pain location	Soft tissue (sides of ankle)	On or near the bone
Swelling	Yes	Yes, often more severe
Bruising	Common	Common
Can bear weight	Usually (mild/moderate)	Often cannot
Deformity	No	Sometimes visible
Diagnosis	Physical exam	X-ray required

If there's any doubt, get an X-ray to rule out a fracture.

Prevention

• Wear supportive footwear for activity
• Warm up before exercise — include ankle stretches
• Strengthen ankle muscles with regular exercises
• Use an ankle brace during sports if you have a history of sprains
• Watch your step on uneven surfaces
• Maintain balance and proprioception — single-leg exercises help
