Nail Discoloration Concern
Hello everyone, I’m a 19-year-old from Asia, and I've noticed a peculiar detail on my right index fingernail. There is a slender dark line that extends from the cuticle all the way to the nail tip, which leads me to believe it’s embedded within the nail itself rather than beneath it. Interestingly, all my other nails appear completely normal. I cannot recall any injury to this finger that could have caused this anomaly. Regarding how long this has been present, I suspect it has been visible for quite some time, possibly a few months, though definitely not exceeding a year. I only became aware of it today when I decided to investigate the cause after noticing it. I’m unable to determine if the line has expanded over time, as I’ve never monitored it closely before. To my eye, the width of the line does not appear to differ significantly from the top to the bottom of the nail. However, I plan to watch it more diligently moving forward. One potential factor I can think of is that I suffered from a severe Vitamin D deficiency last winter, which I was treated for with D3 supplements. My levels normalized over the summer, yet the line appeared afterward. I ceased taking the supplements afterward, which raises the possibility that my Vitamin D levels have declined again, and I might be deficient once more. After conducting a brief search online, I came across concerning information, but I am also aware that various factors might cause such a line. Though the prospect of melanoma seems minimal, I’m not overly anxious about it. I wanted to seek opinions from those who might have more expertise on this matter. I fully understand that consulting with a healthcare provider or dermatologist is the optimal choice, but unfortunately, the wait times for appointments in my area are quite long, and as a college student, I find it difficult to travel far for assistance. Any insights, knowledge, or advice you might share would be immensely valued. Thank you for your support!

It's understandable to feel concerned about changes to your nails, especially when new symptoms appear. A dark line on your fingernail could result from several factors, and while it's good to be cautious, there's often a benign explanation.
Main Points:
- Possible Causes: The line could be related to benign causes such as a splinter hemorrhage, a form of nail pigmentation due to trauma, or a harmless mole (melanonychia). In more severe cases, it can be related to skin conditions or even infections.
- Monitoring Symptoms: Since you plan to keep an eye on this line, it's important to track any changes in size, width, color, or if you develop any new symptoms.
Explanation:
- Nail Changes: Nails can change color for various reasons. You mentioned that it appears embedded in the nail, which usually suggests it's a pigmentation or growth from within, rather than something underneath the nail.
- Vitamin D and Health: While Vitamin D deficiency can affect overall health, it's less likely to cause a specific line on your fingernail. However, maintaining adequate levels is important for your overall well-being.
Next Steps:
- Monitor: Keep a record of the line's appearance over the next few weeks. Note whether it changes in width, color, or if there’s any discomfort or additional symptoms.
- Limit Exposure: Protect your nails from trauma (e.g., avoiding pinching or banging) as this can exacerbate any minor issues and lead to further discoloration.
- Maintain Nutrition: Continue to eat a balanced diet with adequate vitamins and minerals, including Vitamin D. If you suspect you might be deficient again, consider discussing with a healthcare provider when you can, or explore dietary sources of Vitamin D (like fatty fish, egg yolks, and fortified foods).
- Document Concerns: If the line appears to grow or you develop any new symptoms (such as pain or changes in the surrounding skin), note these changes, as they will be helpful information for your healthcare provider when you’re able to see them.
While it's understandable to be concerned, many nail changes are benign. Continue to observe and care for your nails, and make an appointment with a healthcare provider when possible.

My Relationship with Milk Consumption
For nearly two decades, I have predominantly relied on milk as my primary source of hydration, consuming around five liters daily. Although I recognize that this reliance might not be the healthiest choice, my low appetite has perpetually left me underweight. In the past, I attempted to transition to drinking water; however, I noticed a concerning drop in weight along with persistent fatigue. My inquiry is whether there exists a more nutritious method to obtain calories without resorting to solid foods, and ideally, without incurring high costs?
Seeking Help for Ongoing Health Issues
I am reaching out in desperation for assistance! I'm wondering if anyone else has encountered similar health concerns or could recommend medications or specialists I should consider consulting. I'm truly at a loss and need guidance. As a 23-year-old male vegetarian weighing around 48 kg and standing at 5’4”, I have struggled with being underweight since my childhood. This condition has left me feeling utterly drained and overwhelmed. I’m eager to make a change but feel lost regarding where to begin or which healthcare professional to consult. In my youth, I was diagnosed with asthma, which has significantly improved; however, I continue to deal with low immunity, as I frequently catch colds and coughs from minor exposure to cold environments. Additionally, I’ve noticed that for the past few years, my body temperature feels abnormally high compared to those around me. I experience heat more acutely than my peers. Previously, I was quite active and could walk 4–5 kilometers daily without difficulty. Nowadays, even a short walk of 1–2 kilometers or climbing a few flights of stairs leaves me out of breath and exhausted. Even on days of little physical exertion, I feel weak and lethargic, as though all my vitality has been drained. My appetite has always been low, despite my efforts to increase it. I struggle to consume what would be considered an average meal for someone my age. Just two chapatis or a small bowl of rice or lentils fills me up completely, and attempting to eat more causes discomfort. I often find it perplexing how others manage to eat such larger portions. Dining out has become a challenge for me since even half a plate feels overwhelmingly full. Being extremely slender has made it difficult to find clothing that fits well and has adversely impacted my confidence over the years. For around 15 years, I have hesitated to take photographs of myself. Social and professional circles often regard me as younger than I am, sometimes even as a child, which has contributed to my feelings of invisibility and insecurity. My sensitivity to heat has intensified over the last few years. In seemingly normal room temperatures, I start sweating profusely while those around me remain comfortable. During cold weather, even in temperatures as low as 8°C, I don’t wear warm clothing, as I sweat excessively and feel anxious about overheating. The discomfort can escalate to a point where I feel faint from the heat. In my workplace, where the air conditioning is set at a standard temperature, I find it challenging. I begin to sweat visibly, leaving my clothes damp and prompting coworkers to inquire about my wellbeing. I often feel breathless and anxious that I might collapse if I remain there too long. This makes it very difficult to stay at the office or use public transportation, as even air-conditioned buses can feel uncomfortably warm to me. Over the past year, my situation has deteriorated further. I can no longer tolerate hot or even mildly spiced home-cooked meals, which I used to enjoy without issues. Now, even mildly spiced foods lead to excessive sweating, reddening of my face, and an intense burning sensation in my mouth, akin to consuming overly spicy dishes. As a result, my food intake has diminished even more. I often face ridicule for my dietary limitations, and I’m growing weary of trying to explain my condition, especially when my own family doesn't fully grasp the depth of my struggles, which adds to my distress. I am sharing my story because I truly need help. I wish to identify the underlying issues with my health and seek proper medical attention. If anyone has experienced similar problems or can recommend a suitable type of medical professional to consult, I would greatly appreciate your guidance and support during this challenging time. Thank you. 😭
Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.
