Swelling is one of the most common, and most frustrating, parts of recovery after any lower-extremity procedure. Whether you’re dealing with a swollen foot after operation, lingering ankle swelling after surgery, or even a swollen foot after knee surgery or hip procedure, it’s normal to feel unsure about what’s expected and what might be a warning sign.
In this guide, Fall Creek Foot & Ankle explains why swelling happens, how long it typically lasts, when swelling is normal, when it’s not, and how to reduce swelling after surgery safely. You’ll also learn when to reach out to your doctor to make sure your healing stays on track.
Why Swelling Happens After Surgery (And What’s Normal)
Swelling, known medically as edema, is part of the body’s natural response to injury or surgical intervention. After surgery, blood flow increases to the area, carrying nutrients and inflammatory cells needed for repair. This healing process brings fluid with it, which often settles in the foot and ankle.
A swollen foot post-surgery is especially common because the foot is the lowest part of the body. Gravity pulls fluid downward, making swelling more pronounced than in other areas. This explains why some patients experience foot swelling after surgery even when the procedure was higher up the leg. It is not unusual, for example, to develop a swollen foot after hip operation or knee surgery due to changes in circulation and reduced mobility.
Normal postoperative swelling may look like:
- Puffiness that increases throughout the day
- Swelling that improves with elevation
- Mild tightness or discomfort
- Gradual improvement week by week
In most cases, swelling after surgery on foot can last several weeks. Bone surgeries often take longer to settle than soft-tissue procedures.
What’s NOT Normal: Warning Signs to Watch For
Although swelling is expected, certain symptoms may indicate a complication.
Signs of Infection
Contact your doctor if you notice:
- Spreading redness
- Fever or chills
- Increased warmth
- Pus or unusual drainage
- A sharp increase in pain
Signs of Blood Clots (DVT)
This requires urgent attention. Symptoms include:
- Sudden one-sided leg or ankle swelling
- Calf tenderness
- Warmth or redness in the calf or thigh
Compartment Syndrome (Rare but Serious)
Seek immediate care if you experience:
- Severe, unrelenting pain
- A tight or “bursting” sensation
- Numbness or difficulty moving your foot
Circulation Problems
Watch for:
- A bluish or pale foot
- Cool temperature in the foot
- Sudden inability to feel pulses
Hardware or Healing Issues
Some swelling may relate to:
- Screw or plate irritation
- Delayed bone healing
- Increased activity too soon
Any sudden or rapid change in swelling should be evaluated.
How Long Swelling Usually Lasts
Swelling duration varies depending on the type of surgery and your health history.
Typical timelines include:
- Soft-tissue surgeries: 1–4 weeks
- Bone procedures: 2–3 months
- Reconstructive surgeries: 6–12 months
It’s also normal for swelling to:
- Increase by the end of the day
- Flare with heat or humidity
- Return when you resume work or walking
- Appear after long flights or car rides
Certain conditions, such as diabetes, venous insufficiency, neuropathy, and lymphedema, can make swelling more pronounced or slower to resolve. Patients with diabetes should be particularly watchful, as swelling paired with decreased sensation can mask early signs of infection.
How to Reduce Swelling After Surgery Safely
Following proper postoperative care, and always adhering to the post-surgery instructions provided by your doctor, can significantly reduce swelling and improve comfort.
Elevate Your Foot
Elevation helps fluid drain away from the foot.
Aim to elevate above heart level for 20–30 minutes, 3–4 times daily.
Use Compression (If Approved)
Compression socks or wraps help move fluid upward. Always follow your surgeon’s guidance.
Ice Therapy (When Allowed)
Ice can reduce inflammation early in recovery, but not all surgeries allow icing. Never apply ice directly to the skin.
Wear Supportive Footwear
Good shoes provide structure and reduce strain on healing tissue, helping control foot swelling after surgery.
Gentle Movement
Simple movements such as ankle pumps and early range-of-motion exercises can prevent stiffness and improve circulation, especially helpful when dealing with a swollen foot post surgery.
Hydrate and Rest
Staying hydrated supports circulation. Avoid overactivity, which can worsen swelling.

Why You Might Still Have Swelling Months Later
Even months after surgery, swelling can still fall within the normal healing window. Contributing factors include:
- Scar tissue formation
- Increased activity
- Warm weather
- Prolonged standing
- Underlying venous issues
However, swelling that worsens instead of improves deserves a closer look.
When to Call Your Doctor
Reach out to your podiatrist or surgeon if:
- Swelling becomes severe or sudden
- Pain increases instead of decreases
- You notice redness, warmth, or drainage
- You have new numbness or tingling
- One foot is significantly more swollen than the other
- Swelling doesn’t improve after several weeks
- You have diabetes and notice any unusual changes
Your provider can determine whether your swollen foot after operation is healing normally or needs further attention.
