Skin Reactions: Redness and Swelling After Touch

Skin issues

Hello Doctor: For the past year, my skin frequently develops redness and swelling whenever I scratch or when an object touches any part of my body, resembling a mosquito bite.
It takes at least ten minutes for the swelling to gradually subside, and this happens every day, regardless of whether it's summer or winter.
However, my skin does not usually itch; the redness and swelling only appear when I touch or scratch it.
Additionally, the tip of my tongue has started to show small red spots, resembling strawberries.
Could this be a complication? Thank you.

Based on your description, your condition may be urticaria.
There are many potential triggers for urticaria, including food, medications, emotional stress, and temperature changes, among others.
You will need to take medication for a period of time to control the symptoms.
Additionally, it is advisable to limit your intake of foods containing colorings, preservatives, and other food additives, as this may help improve your urticaria.
Please visit a dermatologist for diagnosis and treatment.

More Info

It sounds like you are experiencing a condition known as physical urticaria, which is a type of hives that occurs in response to physical stimuli such as scratching or pressure on the skin. The symptoms you describe—redness and swelling that appear after touching or scratching your skin—are characteristic of this condition. Physical urticaria can manifest in various forms, including dermographism (where the skin reacts to being scratched) and other types that may be triggered by temperature changes, sunlight, or even sweating.

The fact that your symptoms appear only after you touch or scratch your skin suggests that your skin is particularly sensitive or reactive to physical stimuli. This can be due to a variety of factors, including an underlying allergic reaction, skin sensitivity, or even a condition like mast cell activation syndrome, where mast cells in the skin release histamine and other chemicals in response to triggers.

Regarding the redness and swelling on your tongue, this could be a separate issue. The appearance of red spots on the tongue, often described as "strawberry tongue," can be associated with several conditions, including allergic reactions, infections, or even vitamin deficiencies. It is essential to consider whether you have any other symptoms, such as pain, swelling, or changes in taste, which could help narrow down the cause.

Given that these symptoms have persisted for over a year and are affecting your quality of life, it is crucial to consult with a dermatologist or an allergist. They can perform a thorough examination, possibly conduct skin tests or blood tests, and help determine the underlying cause of your symptoms. They may also provide you with treatment options, which could include antihistamines to manage the allergic response, topical treatments to soothe the skin, or lifestyle modifications to avoid triggers.

In the meantime, here are some general tips to help manage your symptoms:
1. Avoid Scratching: Try to minimize scratching or rubbing your skin, as this can exacerbate the redness and swelling. Keeping your nails trimmed can help reduce the risk of breaking the skin.

2. Moisturize Regularly: Use a gentle, fragrance-free moisturizer to help maintain your skin barrier and reduce sensitivity.

3. Identify Triggers: Keep a diary of your symptoms to identify any potential triggers. This can include specific activities, products, or environmental factors.

4. Cool Compresses: Applying a cool compress to the affected areas may help reduce redness and swelling after an episode.

5. Consult a Specialist: As mentioned, seeing a dermatologist or allergist is essential for a proper diagnosis and treatment plan tailored to your specific condition.

In summary, while the symptoms you are experiencing are concerning, they are manageable with the right approach and medical guidance. Do not hesitate to seek professional help to ensure you receive the appropriate care and support for your skin health.
