Swollen lips?


The acne located near the philtrum has persisted for the past two days.
I squeezed it last night and applied a hydrocolloid dressing before going to bed.
This morning, I woke up to find that the area below my lips is swollen.
It is not painful, but the swelling is quite noticeable, while the acne itself is still painful.
The swollen part of my lips is not painful.
Is this cellulitis or herpes labialis? Thank you, doctor.

A literal description without actually seeing the lesion cannot confirm the diagnosis; it is recommended to have a physician evaluate it for proper assessment.

More Info


Swollen lips can be concerning, especially when accompanied by acne or other skin issues near the mouth. Based on your description, it seems you have developed swelling in your lips after manipulating a pimple close to that area. This situation can arise from a few different causes, and understanding them can help you determine the best course of action.

Firstly, the swelling of your lips could be due to localized inflammation resulting from the trauma of squeezing the pimple. This can lead to irritation and swelling in the surrounding tissues, which may not necessarily indicate an infection. However, if the area becomes increasingly red, warm, or painful, it could suggest a secondary infection, such as cellulitis or a localized abscess.

Another possibility is that the swelling could be related to an allergic reaction. If you applied any topical treatments or products after squeezing the pimple, it’s possible that your skin reacted to those substances, leading to swelling. Allergic reactions can manifest as localized swelling, redness, and sometimes itching.

Regarding your concern about whether this is cellulitis or herpes simplex virus (commonly known as cold sores), there are some distinguishing features. Cellulitis typically presents with redness, warmth, and swelling, and it can be associated with pain or tenderness in the affected area. On the other hand, herpes simplex usually presents with vesicles or blisters that can be painful and often occur in clusters. If you notice blisters forming, it could indicate a herpes outbreak.

Given that the area around your pimple is painful, it is essential to monitor the symptoms closely. If the swelling persists or worsens, or if you develop fever, chills, or increased pain, it would be prudent to seek medical attention. A healthcare provider can assess the area for signs of infection and may prescribe antibiotics if necessary.

In the meantime, here are some general recommendations to manage the swelling and discomfort:
1. Avoid Manipulation: Refrain from squeezing or picking at the pimple or the swollen area, as this can exacerbate inflammation and increase the risk of infection.

2. Cold Compress: Applying a cold compress to the swollen area can help reduce swelling and provide relief from discomfort. Make sure to wrap ice in a cloth to avoid direct contact with the skin.

3. Topical Treatments: If you have access to over-the-counter hydrocortisone cream, it may help reduce inflammation. However, avoid applying any products that could irritate the area further.

4. Hydration: Ensure you are drinking plenty of fluids, as hydration can help your skin heal.

5. Avoid Irritants: Stay away from harsh skincare products or makeup that could further irritate the area.

6. Consult a Healthcare Provider: If symptoms do not improve within a few days or if you notice any signs of infection, such as increased redness, warmth, or pus, consult a healthcare provider for further evaluation and treatment.

In conclusion, while the swelling of your lips could be due to various factors, including trauma from squeezing the pimple, an allergic reaction, or even an infection, careful observation and appropriate management are key. If in doubt, seeking professional medical advice is always the best course of action to ensure proper diagnosis and treatment.
