Strange Skin Reactions in Sunlight

8/2/2025, 1:10:29 AMMale25-34

At 27 years old, I’m a woman who isn’t on any prescribed medications but does incorporate supplements like magnesium glycinate and L-theanine into my routine. Recently, I’ve encountered a peculiar issue: whenever I spend time outdoors under the sun and start sweating, I experience intense itching around my neck and chest area. Additionally, red spots and hives appear on my arms. Fortunately, these symptoms tend to resolve within an hour of stepping back indoors. This strange occurrence has persisted for the last two weeks. As someone who enjoys gardening and outdoor strolls, this situation has made exposure to direct sunlight quite bothersome.

It sounds like you're experiencing an unusual skin reaction to sunlight that affects your enjoyment of outdoor activities. The symptoms you've described—intense itching, red spots, and hives upon sweating in the sun—could be indicative of a condition known as solar urticaria, which is a type of allergic reaction to sunlight.

Explanation

When certain people are exposed to sun and heat, their skin may react with hives or rashes. This can occur due to the body's abnormal response to UV light and can cause itching and discomfort. The fact that your symptoms resolve shortly after you withdraw from the sun makes it even more likely that your skin is reacting specifically to sunlight or heat.

Next Steps

  1. Limit Sun Exposure: Start by reducing the amount of time you spend in direct sunlight, especially during peak hours (10 a.m. to 4 p.m.). Consider wearing long sleeves and a wide-brimmed hat when outdoors.

  2. Check for Triggers: Keep a diary of your outdoor activities, noting the duration of sun exposure and any other potential triggers (such as sweat or specific environments) to identify patterns in your symptoms.

  3. Use Sunscreen: Apply a broad-spectrum sunscreen with SPF 30 or higher to all exposed skin. Choose a sunscreen labeled as "for sensitive skin" or "hypoallergenic," as this may help prevent reactions.

  4. Stay Cool and Hydrated: As sweating seems to exacerbate your symptoms, try to stay cool while outdoors. Take breaks in the shade and drink plenty of water to stay hydrated.

  5. Consider Antihistamines: Over-the-counter antihistamines may help relieve itching and reduce hives. Consult with a pharmacist for recommendations and check their suitability for you.

If your symptoms do not improve with these strategies or if they escalate, consider seeking professional evaluation for a specific diagnosis and more tailored treatment options. Your comfort while enjoying gardening and outdoor strolls is important, and these steps should help you manage your symptoms better. Let me know if you need any further information!

Assessing My Health Concerns: How Anxious Should I Be?

I’m a 32-year-old woman, weighing 124 pounds and standing at 5 feet 6 inches tall. For over a year, I have been experiencing bright red rectal bleeding. Initially, I attributed this issue to hemorrhoids that developed during my pregnancy two years ago. The bleeding occurs with most of my bowel movements, sometimes happens without one, and on a few occasions, has been enough to stain the toilet bowl significantly. The color of the blood is typically darker than what I observe during a hemorrhoid flare-up. There is a notable family history of bowel cancer on both sides; one family member was diagnosed at age 45, and another at 60. In the past six months, I have encountered several episodes of severe abdominal pain—3 to 4 instances—intense enough to consider a trip to the emergency room. However, the pain usually subsides within about an hour. It’s unusual for me to experience such acute pain, given my high tolerance for discomfort; for example, I once played rugby shortly after dislocating and fracturing my finger. Recently, I mustered the courage to consult with my doctor, who recommended a FIT test, which returned a positive result (30.1). Additionally, I underwent a complete blood test, and aside from having low ferritin levels (7 µg/L), all other results were normal. I have since been referred for a colonoscopy on a two-week waiting list to rule out any possible bowel cancer. Given these circumstances, how concerned should I be? Thank you for your input.

Understanding Possible Seizure Triggers and Recurrence Risks

Health Background: I am a 21-year-old female, standing at 169 cm and weighing 65 kg. Over the past three years, I have been using oral contraceptives. As of this morning, I started taking 25 mcg of levothyroxine along with a weekly vitamin D supplement of 0.266 mg. Recently, I was diagnosed with hypothyroidism and found to have a vitamin D deficiency that I suspect has existed for the last three years. I do not consume alcohol or smoke, and I can confirm I am not pregnant. Two years ago, I experienced a mild concussion. I currently reside in Spain. A couple of months back, in mid-December, I blacked out twice. The second occurrence took place while I was at the doctor’s office after seeking urgent medical care for the initial incident. Following the second episode, I underwent a CT scan and an EKG, both of which returned normal results. Further tests, as directed by my physician, revealed a critical vitamin D deficiency and hypothyroidism; however, he expressed doubt that either of these conditions led to my loss of consciousness. I was then referred to a neurologist, and I am presently awaiting an appointment. Although the waiting period is lengthy, my doctor indicated that I should receive priority for scheduling, although the exact timeframe remains uncertain. The referral document summarized my events, labeling the second episode (which the physician witnessed) as a potential seizure devoid of tonic-clonic movements—a revelation that took me by surprise. After regaining consciousness, I felt extremely disoriented and terrified, struggling to process what was happening. I have no prior history of seizures, epilepsy, or any related conditions, and there is no known family history of these issues. If this indeed was a seizure, what might have triggered it? Additionally, what is the likelihood of experiencing another one? Since that time, I have not had any further incidents, but I have experienced moments where I felt a sense of impending doom, which I managed to overcome. I intend to wait for the neurologist's evaluation, but the uncertainty surrounding a possible neurological condition is quite distressing. Thank you for any insight you can provide!

Persistent Pain in Right Shoulder and Arm After Lifting

Hello, everyone! I’m a 23-year-old male and have been engaged in weightlifting for several years now. Recently, I’ve been struggling with ongoing discomfort in my right shoulder and arm, which I haven’t been able to accurately identify. The pain manifests during particular movements, especially with lateral raises or when my arm is raised to shoulder level while rotating my wrist. Certain pressing and pulling activities can also provoke this discomfort. Rather than feeling sharp, it’s a deep, nagging sensation that sometimes seems localized in the front area of the shoulder or at the biceps tendon, and at other times it feels more like it’s situated between the shoulder and upper arm. Fortunately, there’s no numbness or tingling involved. This issue began while I was working out. I decided to take a break for around two months, but when I returned, the pain persisted. After consulting a physician, I was diagnosed with bicipital tendinitis. Since then, I’ve reduced my upper-body workouts, completely steering clear of shoulder exercises and heavy lifting, and have begun a gentle rehabilitation regimen focusing on external rotations, pendulum movements, and scapular exercises. Despite adhering to this routine for about a week, I haven’t experienced any noticeable improvement. Is it typical for this type of tendon injury to require an extended period for recovery? At what point should I consider diagnostic imaging, such as an ultrasound or MRI? Additionally, are there frequent rehabilitation errors that might impede the healing process? I appreciate your insights in advance!

INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating

To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.

Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions

Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
