Warning Signs of Complications After Cosmetic Surgery: When to Call Your Clinic

Most symptoms after cosmetic surgery — swelling, bruising, tightness, numbness and mild fever in the first 48 hours — are expected. A smaller, well-defined set of signs indicates a possible complication and warrants contacting your clinic the same day rather than waiting for a scheduled follow-up.

For international patients this distinction carries extra weight. You may be recovering in a hotel, in a different time zone from your surgeon, or already home in another country. Knowing in advance which symptoms justify an urgent call — and having an escalation plan ready before you need it — is a core part of safe medical travel. This guide separates normal recovery from red flags, procedure by procedure, and sets out what to do when you are no longer in Korea.

The Baseline: What Normal Recovery Looks Like

Swelling that peaks around days 2-3 and then steadily declines is the expected pattern for most facial and body procedures. Bruising that appears, darkens, then shifts through yellow-green over 1-2 weeks is normal. Tightness, itching, numbness and altered sensation around incisions are common and usually improve over weeks to months.

A low-grade temperature in the first 24-48 hours is frequently seen after general anaesthesia and is not, on its own, alarming. Mild oozing of thin, pinkish fluid from an incision in the first day or two is also common.

The useful mental model is trajectory. Recovery should be a curve that improves. Symptoms that worsen after having improved, or that appear suddenly several days in, are the ones that deserve attention — regardless of how mild they seem in isolation.

Red Flags: Call the Same Day

The following warrant contacting your clinic without waiting.

Fever above 38°C beginning after the first 48 hours, or any fever accompanied by chills. Early low-grade fever is common; delayed or rising fever is a recognised infection signal.

Pain that increases after having decreased, or pain not controlled by the prescribed analgesia. Escalating pain is one of the more reliable early indicators of a developing problem.

Rapidly expanding swelling on one side, particularly if firm, tense and painful. Asymmetric, rapidly progressive swelling can indicate haematoma, which may require urgent drainage.

Spreading redness extending outward from an incision, warmth to the touch, or red streaking. These are classic cellulitis signs.

Discharge that becomes thick, opaque, yellow-green, or foul-smelling. Thin pink fluid early is common; purulent discharge is not.

Skin that turns dusky, grey, white, mottled or blue-purple, or that becomes cold. This may indicate compromised blood supply and is time-sensitive.

Wound edges separating, or sutures pulling apart.

Any breathing difficulty, chest pain, or new shortness of breath. Treat as an emergency and seek immediate care rather than calling the clinic first.

Calf pain, swelling, warmth or tenderness in one leg. This raises concern for deep vein thrombosis, particularly relevant after longer procedures and long-haul flights.

Emergency: Go to Hospital Now

A small number of presentations should bypass the clinic entirely and go straight to emergency care.

Chest pain or sudden shortness of breath, which may indicate pulmonary embolism.

Confusion, fainting, or a rapid heart rate combined with fever — features suggesting systemic infection.

Uncontrolled bleeding that does not stop with direct pressure.

Sudden vision changes, eye pain, or vision loss after any facial injectable or facial surgery. Vascular occlusion involving the ophthalmic circulation is a recognised, time-critical complication of facial filler and requires immediate specialist assessment.

Severe, unrelenting pain that is out of proportion to the procedure.

In Korea, emergency medical services are reached on 119. Larger hospitals in Seoul maintain international patient services, and facilities accredited for international patients can be identified through KHIDI.

Procedure-Specific Signals

Rhinoplasty: persistent clear watery discharge from one nostril, a sudden change in the nasal shape after the splint is removed, or bleeding that does not settle with pressure and head elevation. Increasing nasal pain with fever after the first week warrants review. Our day-by-day rhinoplasty recovery timeline sets out the expected course for comparison.

Eyelid surgery: sudden severe eye pain with vision change, a tense and rapidly swelling orbit, or inability to close the eye fully. Retrobulbar haematoma is rare but sight-threatening and requires immediate attention.

Breast surgery: sudden asymmetric enlargement of one breast, particularly with firmness and pain, may indicate haematoma. A breast that becomes progressively hard and distorted over weeks to months may reflect capsular contracture, which is not urgent but should be reviewed.

Liposuction and body contouring: fluid collections producing a soft, shifting swelling, increasing rather than decreasing tenderness, skin discolouration over treated areas, and any calf symptoms suggesting thrombosis.

Facial fillers: immediate severe pain during or after injection, blanching or mottled discolouration of the skin, or vision change. These are the recognised warning signs of vascular occlusion and are time-critical — same-hour, not same-day.

Any procedure with implants: fever, wound discharge, or a wound that will not close over an implant site should never be managed by waiting.

Before You Fly Home: Building an Escalation Plan

International patients should leave Korea with the following in writing.

A direct contact route to the clinic that works outside business hours, ideally including a messaging channel your surgeon's team actually monitors, and confirmation of which language support is available.

Your operative note or a procedure summary, including implant details, materials used, and any device serial numbers. A physician in your home country cannot manage a complication safely without knowing what was done.

A written list of medications prescribed, with generic names — brand names differ between countries.

The clinic's written policy on complication management: who pays, whether a return trip is required, and what happens if you are treated locally instead.

A named local physician or clinic in your home country who has agreed in advance to see you if needed. Arranging this before travel is far easier than arranging it at 2 a.m. with a fever.

What to Tell the Clinic When You Call

Be specific and chronological. State the procedure and date. Describe when the symptom started and whether it is worsening. Give your temperature if you have measured it. Describe pain on a 0-10 scale and how it compares with yesterday. Note any discharge — colour, thickness, odour. Photograph the area in consistent, natural lighting and send images if the clinic accepts them.

Do not stop prescribed antibiotics because you feel better, and do not start leftover antibiotics from another source before speaking to a clinician. Both complicate assessment.

Frequently Asked Questions

Is fever always a sign of infection?

No. Low-grade fever within the first 48 hours after general anaesthesia is common. Fever starting after day 2, rising fever, or fever with chills is the pattern that warrants prompt contact.

How long is swelling supposed to last?

It varies by procedure — typically peaking at days 2-3, with most visible swelling resolving over 2-6 weeks and residual deep swelling persisting for 3-6 months in some facial procedures. The concerning pattern is swelling that increases after it had started to settle.

I have flown home and my clinic is not responding. What do I do?

See a local doctor without delay. A complication is a medical problem first and a customer-service problem second. Bring your operative note. Continue trying to reach the clinic in parallel, and document your attempts.

Can I fly with a suspected complication?

Discuss with a physician before flying. Air travel is generally discouraged with suspected infection, active bleeding, or possible thrombosis.

Will asking about complications offend my surgeon?

A surgeon who is uncomfortable discussing complications and escalation plans is signalling something useful about their practice. Established clinics expect these questions and answer them routinely.

Plan Before You Need It

The difference between a manageable complication and a serious one is usually time to treatment. Know the red flags, keep your clinic's out-of-hours contact accessible, carry your operative details, and identify a home-country physician before you travel. If you are unsure whether a symptom qualifies, call — clinics would far rather field an unnecessary question than treat a delayed presentation.
