Red Spots on My Legs: An Unwelcome Surprise
Greetings! This past Saturday, I visited a friend and encountered quite a warm day, exceeding 30°C, which is notably hot for us Europeans. After spending several hours seated, I became aware of numerous small spots emerging across my legs. These dots began just below my knees and extended upwards towards my hips. I occasionally notice similar spots on my arms without any reason, so it was unexpected to see them appearing on my legs in such quantity. I've come across information suggesting that heat can trigger this kind of reaction. However, I should mention that I recently returned from China, where temperatures reached above 33°C coupled with high humidity levels of over 80%. Therefore, this level of heat exposure isn't unfamiliar to me. Additionally, I developed a cold during my flight home, which might also play a role in this situation. I am 34 years old. For allergies, particularly during hay fever season, I take fexofenadine 180 mg daily. I also deal with lipedema, and it’s common for my legs to swell when it's hot outside.

It sounds like you're experiencing an unusual skin reaction with red spots on your legs, particularly after being in the heat for an extended period. This could be related to several factors, including heat rash, allergic reactions, or even a response to your recent cold.
Explanation:
- Heat Rash (Miliaria): Intense heat can cause blocked sweat glands, leading to red spots or bumps. This is common when it's hot, especially after sitting for a long time.
- Allergic Reaction: Since you've been taking fexofenadine for allergies, it’s possible that the combination of heat and recent changes (like air travel or being around new allergens) could trigger a skin response.
- Underlying Conditions: Given your existing lipedema, which can cause swelling and skin sensitivity in hot weather, it might also contribute to skin changes.
Next Steps:
- Cool Compress: Apply a cool, damp cloth to the affected areas for 15-20 minutes several times a day to soothe the skin.
- Hydration: Ensure you’re drinking plenty of fluids to stay hydrated, which can help your body cope with heat and may reduce the swelling.
- Looser Clothing: Wear loose, breathable clothing to prevent further irritation and help keep your skin cool.
- Observe: Monitor the spots over the next few days. If they worsen, change in appearance (like blistering), or if you develop other symptoms such as itching, swelling, or fever, this may warrant further evaluation.
- Avoid Triggers: Try to stay cool and limit exposure to heat until the spots resolve.
If the spots persist or you have significant discomfort, consider your options for seeking medical advice. Remember, these changes are often temporary and manageable with careful attention. Feel free to share any further symptoms or concerns you may have.

Development of Skin Blisters Following Kitten Contact
A 42-year-old woman residing in a warm climate reports a recent skin condition. Approximately three weeks earlier, she experienced a miscarriage and underwent treatment with misoprostol, resulting in significant bleeding that lasted for two weeks. To manage this, she was prescribed tranexamic acid and norethisterone. Around the same time she adopted a stray kitten, she began to notice the emergence of papules about a week ago. Initially, these lesions itched for a day before transforming into blisters and crusted sores accompanied by small pustules. The first sign of infection manifested as a fluid-filled blister on her finger, followed by the development of new lesions on her forearms, shoulders, chest, and inner thigh, with many lesions appearing close to the sites of scratches from the kitten. These lesions are still appearing on a daily basis with no sign of improvement. She has been treating the affected areas with antiseptic solutions, such as chlorhexidine and Octenisept. Unfortunately, she will not be able to consult a doctor in person in the upcoming days. Thank you for your assistance!
Skin Marks on My Girlfriend
My girlfriend, a 24-year-old transwoman assigned male at birth, has been experiencing some concerning skin marks recently. She is currently on a regimen of estradiol and spironolactone. These new spots started to show up just within the last few days, although she previously noticed similar marks when she had a prolonged break from her hormone therapy. She has not been consistent with her medication intake lately, and the heat in her home has been quite extreme, which may or may not be contributing factors. The spots typically begin as reddish or pinkish, eventually transitioning to a brown shade. In contrast, the older spots she had never seem to fade and remain visible. While they are somewhat raised, they are neither flaky nor itchy, and she tends to only become aware of them during casual observations.
Why Do I Get Scars So Easily?
As someone with melanin-rich skin, I often find that even minor injuries like mosquito bites or scratches leave behind lasting scars. It's frustrating to observe how quickly others seem to heal; they might sustain cuts and have them completely mend in just a few days. In contrast, my skin retains these marks for years, leading to a growing sense of insecurity due to their visibility. I'm left wondering if there are effective ways to address this issue. Does anyone understand why my skin reacts this way?
