In short. What the first days after a nasal injection normally look like, what to avoid while the tissue settles, and the changes that mean immediate review.
Key points
- Swelling settles over one to two weeks and the shape then reads closer to its real state.
- Firmness or small irregularities at the injection points are common in this period and usually soften.
- If a written instruction sheet was not given, ask for one, because the rules are short and specific and nobody remembers them accurately afterwards.
The days after a nasal injection are unremarkable in medical terms and disproportionately important to the patient, because this is when the nose looks least like the intended result and most like something has been done to it. Knowing what is expected makes the difference between waiting calmly and telephoning in alarm.
The first three days
Swelling and redness appear within minutes of the injection and are at their most misleading immediately, because they flatter the shape: the dip looks filled, the tip looks right, and none of it has settled. Over the next day or two bruising may appear around the injection points, and the nose looks fuller than intended, often more so than at any later point. Tenderness at the sites is normal. Firmness under the skin is normal and is not the same finding as a lump that develops later. Most people are back to ordinary activity the following day.
What to leave alone in the first week
Strenuous exercise, saunas, hot baths and anything that raises blood flow to the face are usually avoided for a short period, because they increase swelling and bruising. Pressure on the nose is avoided, including sunglasses resting on the bridge, and so is lying face down. Alcohol in the first day or two tends to make bruising worse. Massage is done only if it has been prescribed, and in the way it was demonstrated.
The fortnight that matters more than the first day
Swelling settles over one to two weeks and the shape then reads closer to its real state. Firmness or small irregularities at the injection points are common in this period and usually soften. If a written instruction sheet was not given, ask for one, because the rules are short and specific and nobody remembers them accurately afterwards.
Warning signs that are not settling
Most of what happens in the first days is expected. A small number of findings are not, and they need the clinic rather than a wait. Severe pain, particularly pain that is worsening rather than easing, is the most important. So is skin that has gone white and stays white, or that turns dusky, grey or mottled. Any change in vision, even brief or partial, is an emergency. Spreading redness, warmth, fever or discharge suggests infection and needs prompt assessment.
Telephone the clinic the same day
- Pain that is severe, is out of proportion to the injection, or is getting worse rather than better.
- Skin that has blanched and not recovered, or that has become dusky, grey or mottled.
- Any change in vision, any spreading redness, warmth, fever or discharge.
The three to four week review is where the result is actually judged, and it is worth arriving at it with the photographs taken on the day. Nothing in the first week tells you whether the treatment worked. It tells you whether the tissue is settling in the ordinary way, and that is a question worth an answer rather than a search online at midnight.
Frequently asked questions
How soon after a nasal injection can I go back to normal?
Most people return to ordinary activity the next day. Swelling and possible bruising are visible for several days, so anything involving photographs or a public event is better placed a fortnight later than the following morning. Strenuous exercise and heat are avoided briefly.
Is firmness at the injection point a lump?
Usually not. Firmness and small irregularities in the first fortnight are common while the material settles and the tissue responds, and they often soften on their own. A firm area that is growing, is painful, or is still there weeks later is a different finding and should be assessed.
Should I massage the nose afterwards?
Only if you have been told to, and in the way you were shown. The nose is not a large area and unguided pressure does not improve the shape. Instructions for what to do and what to leave alone should be written down rather than remembered.
Risks & Limitations
- The nose is one of the highest-risk areas on the face for material entering a blood vessel. It is uncommon, it is time-critical, and it is not predictable from the outside.
- The route adds material and cannot remove any. A hump, a wide bridge or a deviated septum is not changed by an injection at any number of sessions.
- Reversal is unreliable. An injected enzyme can break down some substance classes and not others, and it does not restore the shape you started with.
- Each session raises the baseline under the skin. Over years the material that has not yet cleared accumulates, and there is no clean way to take it back.
- Nodules, firmness and small lumps at the injection points, which are common in the first fortnight and usually soften, but do not always.
- Bruising, swelling, tenderness and occasionally a delayed inflammatory reaction, which may need assessment and treatment rather than patience.
- The effect does not last indefinitely, its duration cannot be predicted for one person, and the change is decided as though it were final.
When to Seek Care
- Pain that is severe, is out of proportion to the injection, or is getting worse rather than easing — contact the clinic immediately.
- Skin that has blanched and not recovered, or that has turned dusky, grey or mottled.
- Any change in vision, in any part of the field, however brief — seek emergency care immediately.
- Spreading redness, warmth, swelling, discharge or fever at or near an injection site.
- A firm lump that is growing or painful, appearing weeks or months after treatment.
