Understanding My Unusual Skin Bumps: Should I Worry?
Age: 26, Height: 5'8", Weight: 130 lbs. I have no allergies, except for penicillin, and maintain a typically healthy medical background. During my recent trip to Portugal, I observed the emergence of small, pimple-like bumps on my body, which began appearing almost immediately after my arrival. Strikingly, these bumps are concentrated solely on the left side of my body. The initial appearance was on my left hand, and they've since ascended along my forearm and are now extending towards my left knee. Although I spent two days sunbathing, I did apply sunscreen, albeit with a lower SPF than recommended. Initially, I hypothesized that these could be sun blisters; however, their appearance does not match what I found online, nor do I have any signs of sunburn. Could there be another explanation for these bumps? Having traveled to Portugal annually since my birth, I feel relatively accustomed to the environment here, but is it possible that I’m being impacted by a local allergen? Or is it something fundamentally different altogether?

It’s understandable to be concerned about any changes to your skin, especially when they appear suddenly and in a specific pattern. The bumps you're describing could have various causes, and while many are benign, monitoring them is important.
Main Points
- The appearance of small, pimple-like bumps concentrated on one side of your body could be due to several factors, including irritation, skin reactions, or even possible infections.
- Considering your recent sun exposure, these may be a type of rash or irritation rather than blisters from sunburn.
Explanation
Given that these bumps arose after your trip to Portugal and that you applied sunscreen (even if at a lower SPF), here are some potential explanations:
- Irritation or Allergy: Sometimes, skin can react to products (like sunscreen) or even new environments (climate, humidity, pollutants).
- Folliculitis: This is an inflammation of hair follicles that can look like small bumps, sometimes exacerbated by sweating or exposure to certain materials.
- Viral Exanthems: Certain viral infections can cause localized rash-like bumps, but these would typically present with other symptoms.
- Bug Bites: If you spent time outdoors, bites from insects could also cause localized bumps.
Next Steps
- Monitor the Bumps: Keep an eye on the bumps for changes over the next few days. Note if they increase in number, change color, or if you experience itching, pain, or other symptoms.
- Irritation Reduction: Avoid harsh soaps and skincare products. Instead, use a gentle cleanser and moisturize regularly with a hypoallergenic product.
- Sun Protection: Continue to use a higher SPF sunscreen when outdoors, as sun exposure can lead to irritation and other skin issues.
- Avoid Scratching: Try not to irritate the bumps further, as this could lead to infection.
- Document Symptoms: Keep a brief note of any new developments, where the bumps appear, and any associated activities (such as contact with certain fabrics or products).
If the bumps do not improve within a week, worsen, or if you develop new symptoms like fever or increased pain, seeking advice from a healthcare provider would be wise. This will help ensure an accurate diagnosis and appropriate treatment if needed.

ENT Inquiry: Can Nasal or Sinus Cancer Develop in 3 Months Post-Normal Endoscopy?
Subject: 62 Years Old Gender: Female Background: Long-standing nasal and sinus issues My mother has grappled with persistent nasal blockages, sinus discomfort, and ear pressure for a considerable period. Approximately three months prior, she underwent a flexible fiberoptic nasal endoscopy, which revealed signs indicative of chronic rhinitis and sinusitis. The examination showcased features such as inflamed and discolored mucosa, enlarged nasal turbinates, and the presence of clear mucus. Importantly, no masses or concerning lesions were identified during this evaluation. Additionally, her oropharyngeal examination yielded normal results. However, during a recent ENT consultation, a “suspicious lesion above the middle turbinate” was identified via endoscopy, which prompted a referral for an “urgent” CT scan (scheduled for three weeks from now, as we reside in Croatia). Currently, she does not exhibit any worsening symptoms such as facial swelling, altered vision, or recurring nosebleeds (two notable nosebleeds occurred around a year ago, but she has not experienced any since then). I have a few inquiries: 1. Is it feasible for a malignant tumor in the nasal or sinus region to arise or become significant within a mere three months, given that a fiberoptic endoscopy conducted three months earlier revealed no alarming findings? 2. Considering this clinical scenario, how much more likely could this be a nasal polyp or chronic inflammatory reaction as opposed to a cancerous growth? 3. Is there a possibility that such a lesion existed three months prior but eluded detection during the fiberoptic endoscopy? I greatly appreciate any guidance you can provide regarding these concerns.
Is It Common for a 9-Year-Old to Experience Facial Paralysis for 6 Months?
At the age of nine, I was told by my father that my smile appeared uneven; essentially, the left side of my face seemed partially paralyzed. Although I could still move it to some degree, blinking was a challenge on that side, which often left my eye feeling dry. We visited the hospital that very day, where they administered laughing gas to facilitate a lumbar puncture due to their suspicion of Lyme disease, along with a blood test to rule out other potential issues. The lumbar puncture was intensely painful, a discomfort I had never experienced before, even with the gas administered to dull the sensation. In the end, the test results yielded no conclusive diagnosis—doctors speculated that a nerve might have been inflamed or something along those lines. Despite having access to free healthcare, the experience was frustrating. To manage my symptoms, I used a patch taped over my eye to help retain moisture, which eventually resolved the issue. Though I suspect that nerve swelling was the culprit, I occasionally find myself reflecting on the incident and wonder if other factors could be responsible.
Unexplained Bruises and Welts on My Daughter's Skin
Four nights ago, my daughter developed two noticeable welts on her thighs, which showed no signs of pain or itching. She insisted vigorously that nothing occurred to cause them, and nobody had harmed her. The following day, I noticed that the welts had vanished, leaving behind bruises. This left me quite anxious, fearing she might have sustained an injury. However, since that initial incident, it seems she has developed one or two more welts every evening right before bedtime, which then disappear overnight, only to be replaced by bruises in the morning. Most of these welts have appeared on her legs, ankles, and feet, with the exception of one on her palm that did not result in a bruise. Oddly, none of the welts are itchy, but she mentions that they can be painful when pressure is applied. There's a bit of swelling as well, consistently occurring in the evenings just before she goes to bed. We plan to consult a doctor on Monday, but it's currently the weekend, and I'm curious if anyone has encountered something similar or could have insights on what might be happening.
Navigating Acoustic Neuroma Treatment Options
**Profile: 45-year-old Male, 6'0", 220 lbs, No Regular Medications** My husband maintains a relatively healthy lifestyle despite experiencing some service-related disabilities. About a year and a half ago, he underwent knee replacement surgery, and he utilizes a CPAP machine due to sleep apnea—an issue linked to a jaw surgery performed many years ago. Additionally, he has a history of appendectomy. For the past three years, he has been prescribed hearing aids due to bilateral hearing loss, although he rarely uses them. About eight months ago, he experienced what he described as the "worst headache of his life." Given that he seldom suffers from headaches, we decided to visit the emergency room. A CT scan showed no abnormalities, and he was diagnosed with a migraine. Since then, he has grappled with weekly migraines. He has a triptan medication, but it offers limited relief. Additionally, he has been reporting non-migraine headaches every few days. Before this incident, he reported headaches perhaps twice a year, typically after consuming alcohol, which he does occasionally and in moderation. He also frequently mentions a sensation of pressure or fullness in his head, though he is uncertain if he would categorize it as a headache. Given the stressors our family has faced over the past couple of years, I hoped this might subside as we return to a more typical routine. Two weeks ago, my husband’s boss alerted us that an ambulance was called after he fainted while walking down the hall at work. After regaining consciousness, he attempted to sit up but felt intense dizziness, forcing him to lie back down. Although his fall wasn't witnessed, he was found roughly two minutes later. At the ER, tests including a CT scan and EKG returned normal results. He was then referred back to his primary care manager (PCM), who ordered an MRI with and without contrast. The MRI revealed the presence of an acoustic neuroma. Through my investigation, it appears that many of his symptoms—headaches, pressure sensations, dizziness, and cognitive fog—could be linked to this condition. We are currently awaiting a follow-up appointment with his PCM for a specialist referral. I want to ensure that he is equipped to advocate for himself during this process. Considering his MRI results and associated symptoms, should we seek the expertise of a specialist familiar with acoustic neuroma? I am concerned that our small-town ENT may not have extensive experience with this issue, and I want to avoid a mere monitoring approach if more proactive treatment is advisable. With a busy family and an active lifestyle, his symptoms over these past months have certainly impacted him, as well as our family dynamics and his professional duties. I would greatly appreciate any insights regarding treatment options or specialist locations you might be able to share. Thank you!
Blood in Urine: Seeking Guidance
A 20-year-old female weighing 140 pounds has not been taking any medications or supplements, and has no prior or current medical conditions. Her menstrual cycle last occurred two weeks ago. While at work, she observed blood in her urine, which appeared light red but darker than pink. Accompanying this symptom, she has experienced some abdominal discomfort. Notably, there was no evidence of blood on her underwear, only when she urinated. Additionally, she felt a moment of lightheadedness upon noticing the blood, which has since subsided; she attributes this feeling to her anxiety about the potential seriousness of the situation. Given these symptoms, what could be the likely cause? She is uncertain whether to visit the emergency room or to wait until urgent care is available tomorrow for a consultation. As she recently relocated and does not have a primary care physician yet, her anxiety is heightened.
