Concerns Regarding Severe Vitamin D Deficiency and Medical Advice
For several months, and even spanning a few years, I’ve been facing serious fatigue. After various consultations, I recently learned that my vitamin D levels are critically low at 17 nmol/L. My psychiatrist emphasized that this is alarmingly deficient and suggested I should receive a booster shot, as over-the-counter supplements may not adequately address the issue. However, the GP has advised taking only 800 IU per day. I am aware that there is considerable debate among healthcare professionals regarding vitamin D requirements. After reviewing multiple studies and recommendations, I've chosen to take 3000 IU daily, which aligns with the guidelines suggested by the Dutch health authority, and is readily available in pharmacies. Given that guidelines vary from one country to another, and even among different medical specialties, I want to get your thoughts on my GP's recommendation. I am not seeking to act independently of my healthcare providers but wish to have an informed discussion with them regarding my treatment options. I appreciate your insights!

It's great that you're seeking information about your vitamin D deficiency, as it’s important for your overall health and energy levels. Your current vitamin D level of 17 nmol/L is indeed considered low, and addressing this deficiency is essential. Your concerns about appropriate treatment options are valid, especially as you've received different recommendations.
Explanation: Vitamin D is crucial for bone health, immune function, and overall energy. Low levels can lead to fatigue and other health issues. The variations in recommendations for vitamin D intake stem from different health guidelines and personal health needs. While your psychiatrist suggested a booster shot, which can provide an immediate increase in vitamin D levels, your GP's recommendation of 800 IU daily may be considered conservative by some guidelines, especially in cases of significant deficiency.
Taking 3000 IU daily, as you plan, is generally within safe limits for adults according to many health authorities, including the Dutch health authority, but it is important to monitor your vitamin D levels periodically to avoid potential toxicity.
Next Steps:
- Monitor Symptoms: Keep a daily log of your fatigue levels and any other symptoms you may experience. Note any changes you feel after adjusting your vitamin D intake.
- Adjust Supplementation: Starting with your chosen 3000 IU per day is reasonable, but ensuring that this aligns with your healthcare providers' suggestions will be crucial. Consider discussing this specific dosage openly with your GP.
- Reassess Levels: Plan to have your vitamin D levels retested in 8-12 weeks to evaluate how your body is responding to the increased supplementation.
- Discussion with Providers: Prepare for a discussion with your GP and psychiatrist about the varying recommendations. You might ask about the rationale behind the 800 IU recommendation, the possibility of a booster shot, and your current plan for 3000 IU.
This approach will help you advocate for your health while keeping an open line of communication with your healthcare team.

Seeking Advice on IPL Burn Treatment: Used Beef Fat and Now It's Worse
I recently purchased an IPL device from Temu, and I suspect I've ended up with a burn after using it. I didn't conduct a patch test prior to applying the device to sensitive areas, which was likely a mistake. Following the treatment, I felt a burning sensation that lasted for about two hours. In an attempt to soothe the irritation, I applied beef fat, but it appears to have exacerbated the issue instead. The affected skin has turned a bright red and looks quite inflamed. Could anyone share their recommendations on how to manage this situation? For context, I’m a 19-year-old female looking for guidance.
Seeking Guidance for Unrelenting Itching
It may seem trivial, but I’m a 50-year-old man grappling with relentless itching that began in August 2025. Initially, the discomfort was limited to my upper body, but it has since spread and now affects nearly every part of me, except for my head. I have resorted to using a wire-bristle brush for scratching, sometimes dedicating hours each day to try to find relief. A few weeks after my ordeal began, my wife also began experiencing similar itching sensations. Neither of us struggles with psychological conditions, leading me to believe this isn't an issue of "contagion". In our attempts to address this issue, we have thoroughly replaced all bedding and towels, as well as changed our mattress cover and duvet. We even took the extra step of steaming our carpets and upholstery. On the contrary, we haven't introduced any new pets or altered our use of soap, moisturizers, or cosmetics during this period. At my workplace, there was an outbreak of scabies (as I work in a care home), but our doctor has found no indication of this problem affecting either of us. Nevertheless, we've applied permethrin cream multiple times and have taken ivermectin as a precaution. In addition, we’ve tried various topical treatments, including cooling menthol gel, hydrocortisone cream, Eurax cream, and E45 itch relief lotion, alongside an array of over-the-counter antihistamines such as Benadryl, Claritin, Zyrtec, Piriton, and Allegra. Sadly, none of these remedies have yielded any noticeable improvement. I'm reaching a breaking point and cannot endure this any longer. Together, my wife and I have visited our GP seven times, yet we’ve left each visit without any constructive solutions. I do have a referral to dermatology, but the waiting period in my region is typically between 18 months to 2.5 years before consultations commence. To rule out any potential bed bug issues, I purchased a high-powered magnifying glass, but nothing has been found on our skin. Our GP has examined us multiple times with no observable findings, with the majority of visible irritations stemming from our relentless scratching. If anyone has any suggestions, no matter how unlikely they may seem, I would be immensely grateful.
Are the Small Red Spots Under My Eyes After Vomiting a Cause for Concern?
Hello, I'm a 20-year-old female. Whenever I vomit, I notice small red spots appear around my eyes and on my face. When I was 13, I was diagnosed with HSP vasculitis due to similar, but much larger, spots that developed on my legs. However, no further examination was conducted following that diagnosis. I typically attributed the facial spots to that past condition, but lately, my anxiety has heightened, making me worry about my health. Just earlier, I vomited after eating what I suspect was spoiled food from a restaurant, and now I see those familiar spots. I'm accustomed to them and expected their appearance, as they don't cause any discomfort or itching—they simply exist. My main concern is that, for the first time, there's a small cluster of these spots appearing under my eye. I can't help but fear that it might be something severe like herpes affecting the eye since it has never clustered in that area before. Any guidance or reassurance would be greatly appreciated. I’ll try to share a photo in the comments if that helps.
Dealing with a Sore Throat and Swallowing Challenges
I am a 29-year-old female, standing at 5’4” and weighing 99 kg, living in Canada, and I do not smoke or have any notable health issues. Approximately ten days ago, on January 26, I experienced a frightening episode of choking on popcorn, which led me to become hyper-aware of my throat, swallowing, and breathing. Following that incident, I noticed I was having difficulty breathing and felt a shortness of breath. Thankfully, I was able to consume food, including solids and chilled beverages, relatively normally in the days immediately afterward, although my discomfort began to escalate. By Wednesday night of that same week, my sensations had intensified to the point where I visited the emergency room. Since that time, I have been grappling with a constant sore throat, accompanied by burning sensations, dryness, hoarseness, and an irritating feeling as though something is lodged in my throat or chest. Swallowing has been challenging unless I opt for foods that are soft, warm, or moist. To make matters worse, cold items exacerbate my symptoms, while warm liquids provide some relief. I have also noticed an increase in belching, bloating, occasional tightness in my right chest, and a decrease in saliva production. The medical team initiated treatment with amoxicillin and a brief course of a proton pump inhibitor (PPI). While I can manage liquids and soft foods, eating a variety of other items remains a painful and uncomfortable ordeal due to the persistent throat pain and dryness. Although my symptoms tend to vary throughout the day, they have consistently lingered since my emergency visit. Doctors suspect that my throat may have been injured during the choking incident, but despite the passage of ten days, I have yet to see any improvement. I am seeking guidance on how to proceed and how I can return to my normal state of health.
Understanding Celiac Disease Blood Tests
I'm a 29-year-old woman dealing with several health concerns, including type 1 diabetes, anemia, OCD, anxiety, autism, and a past issue with postpartum hypertension, which has now been resolved. Recently, I underwent three laboratory tests to determine if I may have celiac disease, prompted by symptoms such as constipation, excessive gas, occasional bloating, fatigue, cognitive fuzziness, anxiety, and sporadic skin problems. In 2020, I had a positive antibody test for celiac disease; however, my colonoscopy results were negative, leading me to continue consuming gluten. This month, I had my tests repeated; my endocrinologist ordered them as a follow-up since my recent childbirth. Here are my most recent laboratory results: - **Tissue Transglutaminase Antibodies, IGA**: 69.6 U/mL - **Deamidated Gliadin Antibodies, IGA**: 8.7 U/mL - **Deamidated Gliadin Antibodies, IGG**: 18.4 U/mL Could you help me understand what these results indicate?
