Persistent Rash Concerns: Should I Seek Further Medical Attention?
I am a 24-year-old male, standing at 5 feet tall and weighing 100 pounds. Last Tuesday, I noticed some unusual rashes developing on my upper arm shortly after a two-hour biking trip to the zoo under the sun, despite having applied sunscreen. The itchiness was quite intense, and the rash began to spread down my legs, reaching my ankles, although my torso remained unaffected. I visited an urgent care facility where the diagnosis was identified as a heat rash, something I have never experienced before. I was given a prescription for hydrocortisone valerate 0.2%. Unfortunately, I encountered issues with my insurance preventing me from obtaining the medication. As a substitute, I've been applying an over-the-counter hydrocortisone ointment with a 0.5% concentration. I’m feeling rather anxious as it seems to be continuing to spread. While it appears faint in some areas, the rash is becoming quite unpleasant where it’s showing on my neck. Due to this, I’ve been staying indoors to minimize sun exposure. Could this still be classified as a heat rash? What other conditions might it indicate?

It sounds like you're dealing with a challenging skin issue, and your concerns are very understandable. Given your recent biking trip, the diagnosis of heat rash does seem plausible, but because of the spreading nature and discomfort, it's important to monitor the situation closely.
Explanation
Heat rash, also known as prickly heat or miliaria, typically occurs when sweat gets trapped in clogged pores, leading to inflammation and itchy red spots. It’s common in hot and humid conditions, especially after physical activity. However, the spreading and changing appearance of the rash could also suggest other conditions like allergic reactions, contact dermatitis, or even an infection if not resolving with typical self-care. Seeing it affect new areas like your neck can understandably increase anxiety.
Next Steps
- Continue Using Over-the-Counter Hydrocortisone: Keep applying the 0.5% hydrocortisone ointment to affected areas as directed. This will help reduce inflammation and itching.
- Keep Skin Cool and Dry: Avoid activities that lead to sweating. Wear loose-fitting, breathable clothing to help your skin stay cool, and shower with lukewarm water to avoid irritating the rash further.
- Avoid Irritants: Stay away from harsh soaps and lotions that could aggravate the rash. Instead, opt for gentle, fragrance-free products.
- Monitor Symptoms: Keep an eye on changes in the rash. If it continues to spread, worsens, or starts showing signs of infection (such as increased redness, swelling, or pus), it's important to seek further medical advice.
- Document Changes: Consider taking photos of the rash every few days to track any changes. This could provide helpful information if you later consult a healthcare professional.
If you notice severe symptoms, such as difficulty breathing, or significant swelling in other areas, please seek immediate medical attention.
Most importantly, try to stay calm and take these steps to manage your symptoms. Let me know if you need more specific help or guidance on caring for your skin!

Understanding Petechiae on My Arms
As a 35-year-old woman, I had a complete blood count (CBC) done in March, which returned normal results. There’s a possibility I had another test at the emergency room around June or July, though I'm not entirely certain. Recently, I've noticed the appearance of petechiae—those small, pinpoint red or purple spots on my skin. These spots do not blanch when pressure is applied with a glass, but when I stretch the skin around them, they seem to fade or almost disappear. This development has left me feeling quite anxious. My skin is quite sensitive, and there are also some tiny spider veins on my upper arms in conjunction with these spots. I tend to bruise easily, especially after having my blood pressure measured or while carrying grocery bags, which at first made me think I might have damaged my skin. However, the spots resemble petechiae more than anything else. I’m uncertain what’s happening, especially since my most recent blood work was normal. What might be causing these symptoms?
Experiencing a Sore Spot on the Back of My Tongue?
Greetings! I'm a 28-year-old male currently residing in the UK. Just yesterday, I encountered some discomfort at the back of my mouth while munching on chips. Later that evening, I examined my mouth and noticed that my tongue appeared somewhat irritated, though I’m not quite sure how to describe it accurately. I figured I would reach out here for some insights. Typically, there is no significant pain, but it intensified when I ate the chips. In the days leading up to this, I had only felt a slight tingling sensation, which occurred after consuming moderately spicy foods—like medium heat Nando’s chicken and Texas BBQ-flavored Pringles that I often enjoy for lunch. None of these items had bothered me prior to this week, including the chips. I should also mention that I’ve been dealing with a cough for about a week; however, given that colds have been circulating, I attributed it to that and want to include it for context. For now, I’ve decided to avoid spicy foods, suspecting they might be the culprit due to the tingling. Despite my research, I find myself struggling to pinpoint what exactly this irritation could be, and I’m seeking a clearer understanding. Additionally, for context regarding my medical history, I have asthma and eczema. I manage my asthma with a Flutiform inhaler, which I've been using for several years, and I apply Cetraben cream for my eczema whenever it flares, although that is infrequent lately. Thank you in advance for any guidance you can provide!
Could This Be MS?
I am a man in my mid-twenties who has recently begun experiencing some concerning symptoms. About four days ago, I noticed the onset of mild headaches coupled with discomfort in my neck, along with stiffness. The pain never exceeded a severity of 3 out of 10, making it quite manageable. Two days ago, I encountered a peculiar event where I felt weakness in my right arm for approximately 20 minutes, which eventually subsided. However, last evening, the weakness returned and persisted, prompting me to seek medical assistance at the emergency room. While there, I experienced ongoing weakness in my arm, followed by tingling sensations in both my right and left legs, akin to the feeling of pins and needles. At one point, the tingling intensified to numbness. Today, my calves have been cramping slightly, and the weakness in my arm continues to fluctuate. I consulted with the physician at the ER and also met with my primary healthcare provider today. My doctor suspects that I may be experiencing a form of migraine that is leading to the tingling sensations, though I find it hard to reconcile this with the fact that my headaches have been so mild. I am troubled that these symptoms might indicate the onset of multiple sclerosis (MS). I understand that tingling can be an initial symptom, yet I wonder about the quickness of its onset. In merely two hours, the sensations in my legs changed from normal to a pronounced tingling feeling. Does this scenario align with the early signs of MS, or could there be an alternative explanation for what I’m experiencing?
Seeking Guidance on Ongoing Health Concerns Affecting Well-being
Hello, everyone. This marks my first post here on Reddit, and I'm eager to gather thoughts regarding some health challenges I've been facing recently. I've been dealing with a variety of minor yet persistent health issues, and each time I consult a doctor or specialist, it seems the general response has been uncertainty. I’m reaching out to see if anyone can relate to any of my symptoms or if perhaps there’s a bigger picture to consider with these concerns. Here’s a bit about my situation: I’m a 23-year-old woman, 6 feet tall, weighing 142 lbs, and despite undergoing multiple medical assessments, I generally pass as healthy. Although none of these issues appear to be life-threatening, they have significantly diminished my quality of life as I frequently encounter discomfort or pain. Below, I've outlined my symptoms in detail, along with context regarding the duration and severity of these issues. **Digestive Symptoms** (most troubling aspect) After extensive testing with a gastroenterologist, I've been diagnosed with Irritable Bowel Syndrome (IBS). - **Constipation**: I’ve struggled with this since childhood; however, the frequency has increased, especially correlating with my menstrual cycle over the past two to four years. There have been severe episodes where I have gone over four days without a bowel movement in the last year and a half. - **Difficulty with bowel movements**: This includes pain, straining, and occasionally spotting blood, alongside a reliance on coffee as a laxative nearly every day for the last six months. - **Appetite Issues**: Although I have some normal days, overall, I experience limited hunger cues. I tend to fill up quickly and have difficulty ensuring I consume sufficient calories each day. - **Dehydration**: I suspect I have suffered from a lack of thirst throughout my life. This issue surfaced a couple of years ago and can temporarily improve with electrolyte intake, but without it, my thirst seems to disappear entirely. I recognize the health risks associated with dehydration but find it hard to drink fluids, especially plain water. I can go for long periods without hydration, only realizing it when headaches arise. - **Bloating and Flatulence**: This has become particularly problematic over the last 18 months. Most mornings, I awake with significant bloating, which can be painful enough to disrupt my sleep. The bloating affects my appetite, and I frequently burp and pass gas throughout the day. **Vaginal Concerns** I have a Paragard copper IUD and have been in a monogamous relationship for the last three years. - **Yeast Infections**: I've been prone to these since puberty, averaging about five incidents a year for the past two to four years. Currently, I’m experiencing symptoms reminiscent of a yeast infection, though a recent test returned negative. - **Pain during Intercourse**: In the past two months, I've also begun to suffer from intense pain during sex, with a burning sensation deep inside, reminiscent of a urinary tract infection, although I am currently UTI-free. This discomfort has made it impossible to engage in sexual activities. **Additional Symptoms** - **Severe Fatigue**: My tiredness peaks around my menstrual cycle, but I can't recall the last time I felt energized for longer than two hours. This relentless fatigue affects my ability to drive, leading to bouts of drowsiness, even when I’ve had a full night’s sleep (7-9 hours). - **Muscle and Joint Pain**: A chiropractor recently noted that my spine lacks some of its natural curvature, a discovery I hadn’t encountered before. I only experience hip pain when failing to engage in daily stretching and exercise, leading to immobilizing discomfort. I also endure low back and shoulder pain that tends to arise from standing still too long or from poor sleeping positions. I frequently feel the need to crack my joints to alleviate mild discomfort, but these issues persist. **Additional Context** - Roughly two years ago, I participated as a control in a medical study, and extensive blood tests returned normal results, though I couldn’t continue due to a bout of constipation. - I have a tendency to lock my knees when standing, a behavior I recognized last year and am attempting to correct, though it remains a frequent occurrence. - I have predictable monthly periods, with some fluctuations, lasting 8 to 10 days, often with varying symptoms each time. - I continue to face issues with acne, typically having at least one deep-seated blemish despite following a solid skincare regimen. Thank you to anyone who has taken the time to read through this. I truly appreciate any insights or suggestions on what concerns to discuss with my doctors next. I’m feeling a bit lost and hope to find some potential leads on possible underlying causes for my symptoms.
Understanding Rib Injuries
Hello everyone, I’m a 23-year-old woman, standing at 5 feet 1 inch tall and weighing around 120 pounds. Approximately a week ago, I experienced a fall that resulted in an injury to my rib area. The impact left me with a significant bruise that is dark in color surrounding the ribs, and the pain has made it extremely uncomfortable to touch or move that part of my body. Two days after the incident, I decided to visit urgent care due to the intensity of the pain I was feeling. During my examination, the attending physician suggested that I might have either a dislocated or fractured rib. Although I couldn't undergo an X-ray at that time, the doctor could identify the separation through physical examination. Several days after this initial visit, I had a follow-up appointment with my primary care physician. However, her assessment differed greatly from the first. She recommended an X-ray, which ultimately came back cleared. When I attempted to express my continued discomfort—especially while moving, deep breathing, or pressing on the affected spot—she appeared to dismiss my concerns. Her response was that if I had truly sustained a broken rib, I would likely experience "a lot" of pain, even though I had already shared my symptoms with her. Now, I find myself feeling frustrated and undervalued. She remarked that a rib fracture or dislocation could not be confirmed solely through touch, which raises questions for me. Is it possible for certain rib injuries not to be clearly visible on X-rays? I’m not trying to undermine anyone's expertise; I simply seek clarity regarding my condition and reassurance that my feelings are valid.
