Skin Bumps Triggered by Sun Exposure
Age: 21 Gender: Female Height: 5’7” Weight: 230 lbs Ethnicity: Caucasian/Hispanic Duration of symptoms: Since childhood Location: Texas Relevant medical history: None reported Current medications: None After spending more than thirty minutes in the sun, I develop small clusters of bumps on my arms and hands that are both itchy and sensitive to the touch. These bumps match my skin tone and are not red, making them less noticeable in photographs, which may not depict the issue effectively. Interestingly, my grandmother experiences a similar condition, leading me to suspect a hereditary link. I've dealt with this condition for as long as I can remember. I have searched online for insights, but the examples I found tend to look much more serious than what I'm experiencing. What could this be?

You are experiencing itchy, skin-colored bumps on your arms and hands after sun exposure, which suggests a possible skin condition called solar urticaria, or perhaps an allergic reaction that is influenced by UV rays. Given your family history, it may also be related to inherited skin sensitivity.
Explanation
Solar urticaria is a rare condition where hives develop after sun exposure. The itching and bumps you describe align with this, especially since you mention a family history that may indicate a genetic component. Other possibilities include sun-sensitive reactions, such as polymorphic light eruption, even though this often presents differently.
Prioritized Next Steps
-
Sun Protection: Start using a broad-spectrum sunscreen with SPF 30 or higher. Apply it generously to all exposed skin 15-30 minutes before going outside, and reapply every two hours or after swimming or sweating.
-
Cover Up: When possible, wear protective clothing such as long sleeves and wide-brimmed hats to shield your skin from the sun.
-
Document Symptoms: Keep a record of when the bumps occur, the duration, and any other triggers. This might help you identify patterns related to specific activities or exposures.
-
Antihistamines: Over-the-counter antihistamines can help reduce itching and discomfort. Look for options like diphenhydramine or loratadine.
-
Moisturize: Regularly apply a fragrance-free moisturizer to soothe your skin. This can help if dryness is contributing to irritability.
If symptoms persist or worsen, or if you start to notice other skin changes, consider consulting a dermatologist for a more specific diagnosis and treatment plan. Your concerns are valid, and with the right precautions, you can manage these skin bumps effectively.

Understanding Skin Flushing
A 29-year-old man has been experiencing episodes of skin flushing for the past four months. Initially, these occurrences were limited to situations involving alcohol consumption, which he recognized as a common reaction. However, now he encounters flushing daily, particularly during work or after showering, and it doesn't solely stem from increased body temperature. Despite undergoing numerous blood tests that returned normal results, he remains puzzled as to the cause, as there seem to be no identifiable triggers. An appointment with a dermatologist is already scheduled, as there is speculation that he may have rosacea, a condition he has never previously dealt with. The sensations accompanying these flushes are extremely uncomfortable, causing his skin to feel hot and taut. He is seeking advice on potential explanations or remedies for his condition.
