Recovery after functional endoscopic sinus surgery (FESS) is usually gradual. Although FESS is performed through the nostrils without external facial incisions, your nasal and sinus tissues still need time to heal. It is common to experience congestion, mild bleeding or bloody drainage, pressure, and discomfort during the first several days.
Your recovery can vary depending on the extent of surgery, the sinus condition being treated, whether procedures such as septoplasty were performed at the same time, and your overall health.
Understanding what happens during the first few days and weeks can help you know what is normal and when to contact your surgeon. For an overview of the procedure itself, see our guide to Sinus Surgery (FESS).
What Happens Immediately After FESS?
After surgery, you will spend some time in a recovery area while the effects of anesthesia wear off. Depending on your procedure and medical condition, FESS may be performed as a day procedure or may require a short period of observation.
You may notice:
- Nasal blockage or stuffiness
- Mild facial pressure or discomfort
- Small amounts of blood or bloody mucus from the nose
- A feeling of fullness around the nose or sinuses
- Temporary reduction in your sense of smell
- Tiredness, particularly during the first day after anesthesia
These symptoms do not necessarily mean that the surgery has not worked. In fact, congestion can temporarily make your nose feel worse before it begins to improve.
FESS Recovery: What to Expect During the First Week
The first week is generally focused on rest, controlling discomfort, protecting the healing tissues, and keeping the nasal passages clean according to your surgeon's instructions.
Days 1–2: Congestion and Drainage Are Common
During the first couple of days, your nose may feel very blocked. Some bloody drainage or mucus can also occur. Mild pain or pressure is possible, although the intensity varies between patients.
Your surgeon may recommend keeping your head elevated while resting or sleeping. This can help reduce congestion and make you more comfortable.

You should follow your prescribed medication plan carefully. Depending on your individual case, this may include pain medication, saline rinses and other nasal medicines.
Days 3–7: Healing Continues
By the middle or end of the first week, some of the initial discomfort may begin to settle, but nasal congestion and crusting can still be present. You may also continue to notice mucus or small amounts of blood-tinged discharge.
Do not be concerned if your breathing does not immediately feel better. Swelling inside the nose can temporarily limit airflow while the tissues heal.
Why Is My Nose Still Blocked After FESS?
Nasal blockage after FESS is usually related to postoperative swelling, mucus and crusting rather than the original sinus obstruction returning immediately.
The nasal passages need time to recover from surgery. As swelling decreases and the tissues heal, airflow may gradually improve. The timing is different for every person, so an early assessment of the final result can be misleading.
Saline Rinses After FESS
Saline irrigation is commonly an important part of postoperative care. It helps keep the nasal passages moist and can help clear mucus, blood and crusting while the surgical areas heal.

Your surgeon will tell you when to begin rinsing, how frequently to do it and which method to use. Follow those instructions rather than changing the frequency or solution on your own.
If you prepare saline at home, the water used for nasal irrigation should be distilled, sterile or appropriately boiled and cooled rather than taken directly from the tap.
Will You Need Follow-Up Visits After FESS?
Yes. Follow-up care is an important part of FESS recovery. Your surgeon may examine the inside of your nose with an endoscope and, when appropriate, remove accumulated crusting, dried blood or other material from the healing areas.

These postoperative visits are not simply routine check-ups. They allow your surgeon to monitor healing and identify problems such as excessive inflammation, scarring or persistent disease.
The number and timing of follow-up appointments vary according to the extent of surgery and your individual healing process.
When Can You Return to Work After FESS?
Many people need approximately a week away from work, although this can vary considerably. Someone with a desk-based job may return sooner than a person whose work involves physical exertion, dust, heat or heavy lifting. Your surgeon should determine when you are ready to return based on your recovery and the nature of your work.

How Long Does It Take to Fully Recover From FESS?
There is no single recovery timeline that applies to everyone. You may feel well enough to resume many normal activities within a couple of weeks, while complete healing inside the nose and sinuses can take considerably longer.
It is also possible for symptoms to improve gradually rather than all at once. Nasal breathing, facial pressure, drainage and sense of smell may each recover at different rates.
Your surgeon may also continue or restart certain medical treatments after surgery because FESS does not necessarily eliminate the underlying inflammation that caused chronic sinus disease.
What Symptoms Are Not Normal After FESS?
Some discomfort, congestion and minor bloody drainage can be expected. However, you should contact your surgical team if you experience symptoms that are severe, worsening or significantly different from what you were told to expect.
Seek medical advice for symptoms such as:
- Heavy or persistent bleeding that does not settle
- Severe or worsening pain despite prescribed medication
- Fever or other signs of infection
- Significant swelling around the eyes
- Changes in vision or double vision
- Severe headache, confusion or other unusual neurological symptoms
- Clear, persistent watery drainage that your surgeon has not explained
These symptoms do not automatically mean that a serious complication has occurred, but they should be assessed promptly.
The Bottom Line
FESS recovery is a gradual healing process rather than an immediate return to normal breathing. Congestion, mild discomfort, crusting and some bloody drainage can occur during the early days, while improvement in sinus symptoms may become clearer over the following weeks.
Saline care, prescribed medicines, follow-up examinations and temporary restrictions on activities are all part of protecting the healing sinus tissues. Because recovery varies from person to person, your surgeon's postoperative instructions should take priority over any general timeline.
