Unexplained Skin Redness During Menstrual Cycle
Greetings everyone, I apologize in advance for any awkward phrasing or errors in my writing, as I am using my mobile device and I am not a native English speaker. I am a 36-year-old woman who has noticed a peculiar condition linked to my menstrual cycle. Since the onset of my periods, I have developed skin redness in areas such as my groin, upper abdomen, chest, and neck. This discoloration typically manifests on the first day of my menstruation and tends to fade away after one to two days. The affected areas do not experience any pain, itching, or warmth, and the skin remains flat rather than raised. The appearance is reminiscent of sunburn. I have also observed that this reaction occurs during periods of significant inflammation in my body—such as following a COVID vaccination or experiencing a severe throat infection accompanied by a fever. In my quest for answers, I have consulted four different healthcare professionals: a family doctor, an allergist, a gynecologist, and a dermatologist, but none could provide a definitive explanation for this phenomenon. One suggestion was that the ibuprofen I was taking for menstrual cramps might provoke an allergic response. To test this theory, I abstained from using any pain relief during my next two menstrual cycles, but the issue persisted. While this condition is not particularly distressing to me, I find it intriguing that none of the doctors I consulted have encountered it previously. Therefore, I am reaching out to seek insights or similar experiences from the Reddit community. For context, I do not have any chronic illnesses, I’m not on any medications, I have no known allergies, and all my basic blood tests have returned normal results.

It’s understandable to feel concerned about unexplained skin changes, especially those linked to your menstrual cycle. The redness you're experiencing seems to be a transient phenomenon that coincides with your periods and is not accompanied by symptoms like pain or itching, which is somewhat reassuring. Here's a breakdown of what this may indicate and some next steps to consider.
Summary of Main Points
- Skin redness synchronized with your menstrual cycle may be related to hormonal changes or inflammation.
- The absence of pain, itching, or warmth suggest it's not an acute allergic reaction or infection.
- Your thorough checks have ruled out major concerns, but you can explore a few focused areas.
Explanation
The skin changes you notice could be due to hormonal fluctuations that occur during your menstrual cycle. Hormonal changes can affect inflammation in the body, and in some women, this can manifest as skin discoloration. Your reported episodes following significant inflammation (like after a vaccine or infection) may suggest a body response linked to your immune system or skin’s sensitivity during these times.
Since you've ruled out common allergic reactions and your blood tests are normal, this skin redness might be a benign response to hormonal shifts rather than a sign of a serious underlying condition.
Next Steps
-
Document Symptoms: Maintain a journal of your menstrual cycle and any associated skin changes. Note the exact timing, duration, and any accompanying factors (like stress, diet, or illness) that may correlate. This can help identify patterns.
-
Monitor Skin Care Products: Pay attention to any skin care products or detergents you use around the time of your menstrual cycle. Sometimes, products may cause mild reactions without causing itching or pain.
-
Hydration & Skin Care: Keep your skin hydrated and use gentle, hypoallergenic moisturizers. This can help soothe your skin during sensitive periods of your cycle.
-
Consider Moderate Exercise: Engaging in regular, moderate exercise may help balance hormones and reduce inflammation, which might contribute to skin changes.
-
Communicate with Healthcare Providers: If you notice any next-level symptoms in the future or if the condition changes, seek further evaluation. It may also help to consult a dermatologist specializing in dermatological responses to hormonal changes.
If you find any new patterns, it may be beneficial to discuss these findings with your healthcare provider, who may explore other diagnostic options tailored to your observations. Please remember, while it's good to seek answers, the fact that this condition is not causing you distress is equally important. Always feel free to reach out for support and sharing experiences, as knowledge can often provide peace of mind.

Seeking Insights on a Long-Term Skin Issue
I am a 23-year-old male standing at 5'5" and weighing approximately 55 kg. I don’t smoke, take no medications, and have no significant health complications. Since I was about 10 years old, I have had a persistent rough, white patch on the upper section of my ankle, just above the heel. Initially, it appeared as a wound that became infected, and even after healing, it left behind this patch. This area often becomes itchy, leading me to scratch in my sleep or whenever it flares up. Occasionally, I notice some dead skin shedding, and if I apply too much pressure, it bleeds slightly. While there are moments when the discoloration fades, it inevitably returns. Importantly, it has not spread to any other areas of my skin. The patch is dry, has a rough texture, and is slightly elevated, but it isn’t painful—just frustrating and itchy. I am not on any medications, have never smoked, and do not have any known skin disorders. I grew up in a low-income household in a tropical environment (Philippines), which limited my ability to seek medical advice for this issue until now. Could this possibly be psoriasis, eczema, lichen simplex, or another condition entirely? I appreciate any insights or suggestions for potential treatments. Thank you for your help!
Bumps Above My Breast: Seeking Answers
I'm curious about a couple of small bumps that have developed right above my left breast. They showed up about a month ago, initially leading me to believe that I was bitten by something, especially since I had slept on the ground the previous night. However, a month later, these bumps persist and seem to resemble skin tags now. Additionally, I've noticed some discoloration in the surrounding area, which is causing me some concern. What could this be?
Irritated reddish spot on my big toe
I’m a 26-year-old female, standing at 179 cm and weighing 75 kg. My ethnicity is Caucasian, and I am not currently on any medications. Additionally, I don't smoke and I have a history of eczema. For the past few weeks, I have observed a flat, reddish mark appearing on my big toe. Initially, it was not itchy, but over time, it has slightly expanded and has started to itch. Notably, it remains flat without any lumps or raised edges. The spot presents as a pale red circle, with a smaller and darker red circle at its center. It doesn’t resemble a bug bite, yet I remain uncertain about its nature. Although I have eczema, I haven't experienced an outbreak quite like this before. I understand this may seem trivial, but I'm doubting whether to apply antifungal cream, steroid cream, or consider another treatment. Any suggestions on how I might alleviate this discomfort would be appreciated.
Considering Treatment for Thinning Hair
Is it time to explore treatment options? Over the past two years, I have observed a noticeable decrease in the fullness of my hair. As a 21-year-old male soon to celebrate my 22nd birthday, it's concerning to see such changes. Currently, my hair appears significantly thinner and lacks vibrancy, especially when compared to photos from earlier in 2023, where it looked much denser and healthier. I suspect the thinning is particularly evident at the crown of my head. Recently, I had blood tests performed, and the results indicated that my ferritin levels were alarmingly low at just 8. The physician's assistant I consulted merely suggested that I begin taking Ferrous Sulfate (which I’m currently taking at a daily dose of 65mg along with vitamin C) and recommended the use of biotin-infused shampoo and conditioner. Unfortunately, I wasn’t probed about potential causes such as gastrointestinal bleeding or other issues related to blood loss. I’m eager to schedule another appointment with a different healthcare provider in hopes of receiving more comprehensive guidance on this matter.
Seeking Guidance on Recent Skin Issues
Greetings! I'm a 24-year-old assigned female at birth, and I currently only take daily vitamins, specifically vitamin C and ashwagandha. Lately, I've experienced two red flare-ups on my neck, which I will share in the comments. I'm unsure whether these are allergic reactions. Both instances occurred without any changes to my daily routine, which I documented prior to the flare-ups. I have not been diagnosed with any allergies, so if this is an allergic response, it would be something new for me. Another possibility I'm considering is a contagion from my ear. I recently reinserted an earring in my mid-ear, which subsequently flared up, resulting in keloids and discomfort. Regarding the redness on my neck and ear, it hasn’t been very painful, just warm to the touch and slightly bothersome. I have also noted some instances of mild shortness of breath accompanying the flare-ups. I contacted a health hotline for advice, and they suggested that I wait for a doctor's appointment rather than going to the emergency room. Unfortunately, I can't secure an appointment for nearly another month. Any assistance or advice would be greatly appreciated!
