Key Takeaways
- The first days and weeks after surgery carry the highest complication risk.
- Most post-operative discomfort is normal, but certain symptoms require urgent evaluation.
- Fever after surgery always warrants prompt medical attention.
- Signs of blood clots (leg swelling, chest pain, shortness of breath) are emergencies.
- When in doubt, contact your surgical team — they prefer questions over missed complications.
Knowing which post-operative symptoms are normal and which require urgent attention helps you respond appropriately during your recovery. While most discomfort after surgery is expected and manageable, certain warning signs indicate potentially serious complications that need immediate evaluation.
What Post-Operative Symptoms Are Normal?
Pain
Moderate pain is expected immediately after surgery. Pain should gradually improve over days and weeks.
- Expected — pain controlled with prescribed medications, improving daily
- Concerning — pain suddenly worsening after a period of improvement; pain unresponsive to medications
Swelling
Significant swelling develops immediately after surgery, typically peaking around days 3–5, then gradually decreasing over weeks.
- Expected — swelling present but slowly improving; controlled with elevation, ice, and compression
- Concerning — swelling suddenly worsening; severe uncontrolled swelling
Bruising
Bruising around the surgical site is common and typically fades over 2–3 weeks, changing colour as it resolves.
What Warning Signs Require Immediate Attention?
Signs of Infection
Call your surgeon immediately for any of these signs:
- Fever above 38.3°C (101°F) — any fever within the first two weeks post-surgery requires evaluation
- Increasing redness spreading beyond the incision area
- Wound drainage that is cloudy, foul-smelling, or increasing
- The wound opening or separating
- Increasing warmth or tenderness around the incision
- Chills or feeling very ill
Signs of a Blood Clot in the Leg (Deep Vein Thrombosis)
Seek immediate medical evaluation for:
- One leg significantly more swollen than the other (beyond expected surgical swelling)
- Calf pain or tenderness, especially worse when flexing the foot upward
- One leg feeling warmer than the other
- Redness or skin discolouration on the swollen leg
Signs of a Blood Clot in the Lungs (Pulmonary Embolism)
Call emergency services immediately for:
- Sudden shortness of breath
- Chest pain, especially with breathing
- Rapid heart rate or palpitations
- Dizziness or fainting
- Coughing up blood
Signs of Compartment Syndrome
Requires urgent surgical evaluation:
- Severe, unrelenting pain disproportionate to the injury, not responding to medications
- Pain with passive stretching of muscles in the affected area
- Progressive pain worsening despite elevation and medication
- Numbness or tingling
- Late signs: pale or mottled skin, coolness, weakness, or paralysis
Signs of Nerve or Circulation Problems
- Progressive numbness or weakness in the toes, fingers, or limb
- Loss of sensation to touch or temperature
- Colour changes (the limb becoming pale, bluish, or mottled)
- The operated limb feeling significantly cooler than the opposite side
Other Symptoms Requiring Evaluation
- Persistent vomiting preventing medication or fluid intake
- Inability to urinate (particularly after spinal anaesthesia)
- Severe constipation (common with opioid pain medications)
- Significant weight loss after surgery
- A wound that suddenly opens or separates
What Should I Do If I’m Uncertain?
When in doubt, err on the side of caution:
- Call your surgeon’s office and describe your symptoms
- If it is after hours and you cannot reach your surgeon, go to the emergency department
- Bring your discharge papers, medication list, and surgeon’s contact information
- Describe all symptoms clearly and completely
What Information Should I Keep Readily Available?
- Your surgeon’s office phone number (daytime and after-hours)
- Hospital phone number and location
- Emergency department location
- A list of your current medications and allergies
- Discharge instructions from your surgery
Expert FAQ
How much pain is normal after surgery?
Moderate pain is expected and should be manageable with prescribed medications. Pain should gradually improve each day. Sudden worsening of pain after a period of improvement, or pain uncontrolled by medications, warrants evaluation.
When should I call about a fever?
Any fever above 38.3°C (101°F) within the first two weeks after surgery should prompt a call to your surgeon. Fever is one of the earliest signs of infection.
How do I know if swelling is normal or concerning?
Swelling is expected after surgery, typically peaking around days 3–5 then gradually improving. Concerning signs include a sudden increase in swelling, severe swelling in one leg only, or swelling accompanied by redness, warmth, or pain.
Should I stop taking blood thinners if I notice bruising?
No. Do not stop prescribed blood thinners without discussing it with your surgeon. Some bruising is expected while on blood thinners. Contact your surgeon if bruising is severe or spreading unexpectedly, but do not discontinue medications on your own.
Remember: your surgeon would rather receive a call about symptoms that turn out to be normal than have a serious complication go unrecognised. Don’t hesitate to reach out if you’re concerned.
