Mysterious Red Bumps on Thighs, F24
Hello everyone, I recently discovered some red bumps on my thighs that appeared quite suddenly two days ago. They aren't the usual ringworm shape—rather, they are a bit irregular, neither completely flat nor perfectly rounded. Thankfully, they're not extremely itchy; in fact, I only realized they were there when I was showering. To clarify, I've never experienced hives or urticaria, so I’m a bit puzzled about what could be causing this. I did briefly consider the possibility of bed bug bites. However, there’s been no indication of bed bugs in my home, and the bumps are dispersed rather than arranged in any specific pattern or cluster. Also, is there any chance that these could be linked to heat? I ask because we spent the whole weekend outside, and I foolishly opted to wear thermal leggings. Thanks for any insights!

It sounds like you’re experiencing some unusual skin changes on your thighs, which can be concerning. Red bumps that appear suddenly can have various causes, including allergic reactions, heat rash, insect bites, or even skin irritation.
Main Points:
- You may be dealing with a heat rash or an allergic reaction.
- Monitoring symptoms is key, especially since they are not itchy and have appeared recently.
Explanation:
-
Heat Rash: Given your outdoor weekend and thermal leggings, it's possible these bumps are a heat rash. This occurs when sweat ducts become blocked, causing small red bumps, especially in areas prone to sweating. This could explain their sudden appearance as well.
-
Allergic Reaction: These bumps could also be a mild reaction to something you came in contact with, whether it be a fabric, detergent, or even a new soap. Since you've noted no itching, this could be less likely.
-
Insect Bites: While you considered bed bugs, it’s also worth noting that other insects (like mosquitoes or fleas) can leave small red bumps. The dispersion without a specific pattern you mentioned is less typical for bug bites, however.
Next Steps:
-
Cool Down: Try to avoid sweating or overheating. Wear loose, breathable clothing and keep the affected area cool.
-
Moisturize: Use a gentle, fragrance-free moisturizer to keep the skin hydrated, which may help in case the bumps are related to irritation.
-
Monitor: Keep an eye on the bumps over the next few days. Look for changes in size, shape, or color, and note if any new bumps appear.
-
Avoid Scratching: Try not to scratch the bumps, as this can lead to infection or worsen irritation.
If the bumps persist beyond a week, change in characteristics, or you develop other symptoms like itching, swelling, or fever, consider seeking medical advice for further evaluation and treatment. In the meantime, try to stay relaxed as many skin concerns can resolve with time. Let me know if you have any further questions!

Seeking Insight on Health Concerns and Whether Medical Attention is Necessary
I’m a 17-year-old assigned female at birth, and I want to share some health concerns that have been troubling me, particularly given my family’s medical history. My mother’s side has dealt with various issues including low iron levels, autoimmune disorders (like Postural Orthostatic Tachycardia Syndrome), and Ehlers-Danlos Syndromes, both classical and vascular types. In contrast, my father’s family has mostly experienced blood pressure difficulties and celiac disease, though not to the same extent as my mother’s side. I’ve given a brief overview of my family background, and I can provide more details if necessary; however, I’m uncertain about what other information might be relevant. Recently, I have been experiencing a series of unusual symptoms. One of the most alarming occurrences is that when I stand up, my vision sometimes darkens momentarily—this can last for several seconds or, at times, a little longer (though I can't measure it precisely, it definitely resolves in under a minute). This phenomenon has been going on for what feels like approximately three years, and it seems to happen more frequently now, occasionally up to several times a day. Additionally, I struggle to remain standing still for long durations before feeling dizzy and having trouble with my breathing, a problem I’ve faced for years. For clarity, I am not significantly overweight; I maintain a healthy weight for my height and even lift weights at the gym 2 to 3 times a week. On school days, I typically walk over 4 miles. I usually stay hydrated, although I sometimes neglect my water intake when I’m visiting others. Chronic fatigue has been a constant in my life; I generally sleep between 7 to 8 hours each night, often accompanied by a nap lasting an hour or two. While my family’s diet isn't the healthiest, it includes vegetables, and despite having experienced minor eating disorders in the past, I currently manage to eat at least two meals daily, sometimes more. I don’t believe my symptoms stem purely from my lifestyle choices. I tend to bruise easily, with some bruises appearing mysteriously and lasting longer than expected. Friends have even asked if I suffer abuse due to the number of bruises on my legs, but I assure you, I don’t engage in any sports that could cause this. Additionally, I experience daily nausea that can intensify to the point of almost vomiting. Dizziness is a regular issue for me now, though I recall it being much harder to induce in my childhood when I would spin around just to show I wouldn't get dizzy. There was one day when dizziness overwhelmed me so much that I had to leave school. Despite eating and drinking water, it persisted throughout the day, leading my friends to question if I was intoxicated due to my slurred speech and unstable posture. Curiously, that day coincided with my menstrual cycle, which I typically don’t notice affecting me this way. I abstain from alcohol, smoking, or any illicit drug use. I know there are more symptoms, but I can't recall them at the moment. I’m reaching out to see if anyone might have insight into what could potentially be going on with my health. Should I consider visiting a doctor? I’m open to providing additional information if needed. Thank you for reading through this long message!

Understanding Paroxetine Interactions with Diet
Greetings! I'd like to share my experience regarding the combination of paroxetine and diet. For the past two months, I've been using daparox (a form of paroxetine) in liquid form while adhering to a well-rounded Mediterranean diet rich in local, natural, and organic ingredients. At 22 years old, I consider myself in good health and have not encountered any significant issues with the antidepressant, nor have I had any concerns about its interaction with various substances, as I abstain from alcohol and smoking. The only sulfite-containing item I use is wine vinegar, and I do so sparingly. Recently, I’ve found myself enjoying ripe grapefruit, especially when paired with brown sugar. However, I've noticed some adverse effects, likely due to paroxetine's metabolic interactions with this fruit. It's worth mentioning that no healthcare professionals informed me about the need to avoid grapefruits. As I’ve ceased eating them, I am now concerned about whether this could have repercussions for my health. Additionally, I would like to know if there are other foods that I should steer clear of while on this medication.
Frustrations with Seeking Medical Testing
M/27, 5'8, 175 lbs, non-smoker, residing in the UK. For several years, I have been grappling with persistent symptoms that can be categorized as fatigue and various unusual sensations, such as tingling in different areas of my body. These occur even when I get a reasonable amount of rest, and at times when I shouldn’t feel tired at all. Considering my symptoms along with my family history—having relatives who suffered from severe multiple sclerosis (MS), including an uncle who passed away due to it long before I was born—I’ve been wanting to undergo testing for both MS and Epstein-Barr virus (EBV). I suspect I contracted EBV some time ago, and I've read that there may be a connection between this virus and MS. Given that testing for MS can be rather complicated, I opted to start with an EBV test, which is a straightforward blood examination. After doing my homework regarding potential antibody types detectable following an initial infection, I discovered that two key antibodies, EBNA IgG and VCA IgG, could indicate prior EBV infection status. It’s worth noting that during my childhood, I frequently fell ill, sometimes 5-6 times annually; hence, if I did contract EBV, it likely happened long ago. Eventually, resigning to the fact that I needed to consult a medical professional—after numerous visits where my concerns were disregarded—I approached a pathologist to request the blood tests. Upon presenting my specific requests, described by him as “extremely specialized,” he bluntly refused to conduct the tests, suggesting that I should “read less online.” Leaving his office, I was left questioning whether my request was truly unreasonable. It baffles me why he deemed a simple blood test too much to handle. For context, I understand that a significant portion of the population, around 90%, has EBV. This widespread prevalence should not render requesting a blood test peculiar, especially as knowledge about one’s health is important. Additionally, I had experienced multiple illnesses this year; another doctor implied I might be infected with cytomegalovirus (CMV), but again, failed to order any diagnostic testing. Now, I find myself at a crossroads. I am eager to take this test, as it holds significant importance to me, and I feel rather obsessive over it. Although I typically do not seek medical attention often, my physical condition has deteriorated over the past few years, prompting me to seek answers. However, if consulting doctors results in being dismissed for merely inquiring about a medical test, perhaps I should resign myself to living without concern for any potential health issues, be they genetic or otherwise. What’s your perspective on this situation?
