Strange Skin Reactions in Sunlight
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
-
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.
-
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.
-
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.
-
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.
-
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!

Will My Hips Return to Their Original Shape After Recovery?
Hello, I'm a 19-year-old female, and I once had curvy hips. Unfortunately, I experienced cellulitis that resulted in significant open wounds on my sides. As I continue to recover, I’ve observed an inward curve at my hips near the area of the wound, creating what appears to be a pronounced hip dip. Could this be attributed to skin maceration, or might plastic surgery be a necessary option for me?
Chronic Ear Discomfort and Hearing Challenges Post-Infection
I’m a 29-year-old male who maintains a straight-edge lifestyle, avoiding smoking, alcohol, and drugs. My primary health issue revolves around persistent sinus problems. About two years ago, I contracted an ear infection in my right ear, something I had experienced before, having one every year or two. However, this episode was distinct; after the infection cleared, I found myself dealing with ongoing ear complications. For the last two years, my right ear has been a source of continuous discomfort. It often feels clogged, and it seems as if there’s a weight of approximately 5 to 15 pounds pressing down on that side of my head all the time. Furthermore, there’s a noticeable difference in volume between my ears; my right ear seems to operate at about 75% capacity compared to the full strength of the left. The most frustrating aspect is when I wear over-ear headphones—essential for my audio work where I spend countless hours using them. After about half an hour of wearing them, I experience significant pressure on the right side of my head, which extends beyond just my ear and into the surrounding area. Prior to this infection, I had no issues with headphones. Another troubling symptom is that when I attempt to equalize the pressure in my ears—by pinching my nose and blowing—I always find that my right ear pops and feels kind of bubbly. I have explored various ways to ease these sensations. Given my background with ear infections, this prolonged issue is unusual; typically, they resolve in about a week. Unfortunately, many ENT specialists I’ve consulted seem limited in their treatment options. They usually prescribe ear drops and leave it at that, without suggesting decongestants. I also hesitate to use over-the-counter remedies without a physician's approval. In my quest for relief, I have tried numerous home remedies, such as frequently attempting to pop my ears, chewing gum, using a warm washcloth while resting, and performing saline nasal washes. Regrettably, none of these approaches have yielded positive results. I’ve read that others with similar experiences suspect Eustachian Tube Dysfunction (ETD), which might be the underlying issue. At this point, I would genuinely appreciate any advice or assistance.
Concerns Over Multiple Nerve Compression
Hello, Doctors, I’m a 23-year-old female with several medical diagnoses, including ADHD (2025), ASD (2022), endometriosis (2020), costochondritis (2017), bilateral congenital hip dysplasia (2002), patella alta accompanied by maltracking and fat pad impingement (2014), snapping hip syndrome (around 2015), and bilateral carpal tunnel syndrome (2025). I also possess hypermobility and am planning to further explore this condition with my physician. Lately, I have been experiencing symptoms indicative of cubital tunnel syndrome, yet my ultrasound did not reveal any compressive issues. My physiotherapist believes that these symptoms may stem from tightness in my shoulder muscles. Additionally, for more than five years, I have frequently experienced sensations of pins and needles in both my legs and feet during mild stretching activities, such as performing an L-sit or even while bending over to touch my toes. I usually attributed this to being inflexible and having tight muscles, but after mentioning it to my physical therapist, she pointed out that it could be nerve-related, suggesting I try nerve flossing. Furthermore, I've recently endured shoulder discomfort that has intensified, resulting in sharp pain radiating down my upper arm and tingling extending from my forearm into my hand. I sought urgent care yesterday due to the severity of the pain, and they have referred me for an MRI to assess potential cervical radiculopathy. Despite being engaged in physical therapy since I was about ten years old, I rarely experience significant relief or improvement. My inquiry is as follows: why might I have such numerous areas of suspected nerve compression or entrapment? Beyond physical therapy, what additional measures could I take to support my nerves or avert further complications? I am experiencing constant pain, and my situation seems to be deteriorating, even while adhering to the guidance of my doctors and physical therapists.
Seeking Guidance on Ureaplasma Treatment
Greetings, I recently received a positive diagnosis for Ureaplasma urealyticum. Previously, I underwent a course of doxycycline; however, the medication caused severe pressure in my head, discomfort behind my eyes, increased anxiety, heart palpitations, blurry vision, and weakness in my left arm. Considering these adverse effects combined with the risk of idiopathic intracranial hypertension (IIH), I am reluctant to use doxycycline again, despite it being the standard initial treatment for this infection. My healthcare provider has prescribed a week of minocycline; yet, I understand it belongs to the same antibiotic class. I am uncertain about the likelihood of experiencing similar side effects with minocycline, or whether it is advisable for my situation. I also have a prescription for 2.75 grams of azithromycin to be taken over the next six days. While my research suggests that azithromycin is an accepted treatment option, feedback from the ureaplasma subreddit casts doubt on its efficacy. I would appreciate any insights or guidance on how to proceed with my treatment. About me: 26 years old, 5’6”, weighing 250 lbs, non-smoker with occasional alcohol consumption. Current medications include elderberry gummy, albuterol inhaler, Triamcinolone 0.5%, atorvastatin 20 mg, omeprazole 40 mg, and mesalamine suppository.
Seeking Guidance for Ongoing Wrist Pain
Hello everyone, I’m a 19-year-old female in need of some insights or suggestions regarding my ongoing wrist discomfort. Recently, I experienced significant pain in my wrist to the extent that I struggled to move it, prompting me to consult my physician. Following my visit, she arranged for an X-ray to rule out any fractures, which fortunately returned normal results. A couple of weeks later, I was referred to an orthopedic specialist who conducted another X-ray, again showing no abnormalities. However, he decided to proceed with an MRI, which revealed inflammation along with a ganglion cyst that isn’t apparent externally (an occult ganglion cyst, perhaps?). He mentioned that this cyst could potentially be pressing against a nerve, explaining the discomfort I’ve been experiencing. Unfortunately, his only advice was to take two ibuprofen. I followed his suggestion for a few days but hesitated to prolong the use of pain medication due to concerns about its impact on my health. To find relief, I’ve experimented with home heat therapy and initially used a brace, though it made my hand overly sweaty and uncomfortable. I later transitioned to an ace bandage, which was an improvement. At present, I’m not using anything, but the pain persists, significantly disrupting my daily activities. My wrist feels weak, and occasionally, the pain radiates to my thumb. I also notice a slight cracking or popping noise when I move my wrist, which I presume might be related to air bubbles, but I’m uncertain. Moreover, the orthopedic specialist didn’t provide clarity on the precise location of the cyst nor much detail overall, leaving me in a bit of a quandary about my next steps. I’m contemplating whether to return to the orthopedic office or seek a second opinion from another professional.
