After a fever, red spots appear all over the face (the skin remains smooth)?

Hello Dr.
Huang: A few nights ago, I experienced a sudden high fever and persistent vomiting.
The next day, my family pointed out that my face was covered in red spots.
Initially, I thought it was acne, but when I looked in the mirror, I was shocked to see so many red spots on my face (only on my face).
They are not itchy, and there are no raised or depressed areas when I touch them.
Now, on the third day, my overall condition is gradually improving.
The doctor prescribed me gastrointestinal medication, antipyretics, and allergy medication, and my cold symptoms have improved significantly.
However, the condition of my face has not shown any improvement, which is quite concerning...
I would appreciate your insights, Dr.
Huang.
Thank you!

More Info

The appearance of red dots on the face after experiencing a fever can be concerning and may have several underlying causes. Based on your description, it seems that you had a high fever accompanied by vomiting, and now you are noticing red spots on your face that are not itchy or raised. While I cannot provide a definitive diagnosis without a physical examination, I can discuss some potential causes and considerations regarding your symptoms.

1. Viral Exanthems: After a fever, especially if it was caused by a viral infection, it is common for individuals to develop a rash or red spots on the skin. This is often referred to as a viral exanthem. Common viral infections that can lead to such rashes include measles, rubella, and roseola. These rashes typically resolve on their own as the viral infection subsides.

2. Petechiae: The red dots you are seeing could also be petechiae, which are small, pinpoint red spots that occur due to bleeding under the skin. This can happen after severe vomiting or straining, which can cause tiny blood vessels to break. If these spots do not fade when you press on them (a test known as the "glass test"), it is important to seek medical attention, as it could indicate a more serious condition.

3. Allergic Reaction: Another possibility is that the red spots are a result of an allergic reaction to medications you may have taken, such as the gastrointestinal or allergy medications prescribed to you. Drug rashes can manifest in various ways, including red spots or hives. If you suspect this might be the case, it is crucial to contact your healthcare provider.

4. Infectious Diseases: Certain infectious diseases can cause rashes that appear after fever. For example, conditions like scarlet fever or even some forms of bacterial infections can lead to skin manifestations. If you have other symptoms, such as a sore throat or unusual fatigue, this could be a possibility.

5. Dermatological Conditions: Conditions like acne or rosacea can also cause redness and spots on the face, but these are typically chronic issues rather than acute ones following a fever. However, stress from illness can exacerbate these conditions.

6. Post-Inflammatory Erythema: After an inflammatory process, such as a fever or infection, the skin may remain red for some time even after the initial cause has resolved. This is known as post-inflammatory erythema and usually fades with time.

Recommendations:
- Monitor Symptoms: Keep an eye on the red spots. If they change in appearance, increase in number, or if you develop new symptoms (such as fever returning, swelling, or pain), seek medical attention promptly.

- Avoid Irritants: Try to avoid harsh skin products or treatments until you have a clearer understanding of what is causing the red spots. Gentle skincare is advisable.

- Consult a Dermatologist: If the red spots persist or worsen, consider seeing a dermatologist. They can provide a thorough examination and may perform tests to determine the exact cause of your symptoms.

- Follow-Up with Your Doctor: Since you have already been treated for a fever and other symptoms, it’s a good idea to follow up with your primary care physician regarding the red spots, especially if they do not improve.

In conclusion, while the red dots on your face may be a benign post-viral reaction, it is essential to monitor your symptoms and consult with a healthcare professional if you have any concerns. Your health and peace of mind are paramount, and a medical professional can provide the best guidance tailored to your specific situation.
