Understanding Low B12 Levels
A 46-year-old woman, standing at 5 feet 6 inches tall and weighing 185 pounds, inquired about the potential effects of low vitamin B12 levels. Despite being generally healthy, she experienced symptoms such as nausea and general fatigue. After reviewing her medical chart, she noticed that her B12 levels were below normal, prompting her curiosity about the possible connection. With a scheduled appointment with her physician later this week, she expressed surprise at her low B12 status, especially since she regularly consumes meat, which is typically a good source of this vitamin.

Low vitamin B12 levels can lead to a variety of symptoms, including fatigue and nausea, as you've experienced. B12 is crucial for nerve function, red blood cell production, and DNA synthesis. Even with a meat-rich diet, some individuals can have low B12 due to factors like absorption issues or specific medical conditions.
Explanation:
- Symptoms of Low B12: Fatigue, weakness, nausea, and other nerve-related issues (like tingling in hands or feet) can be a result of low B12 levels.
- Causes of Low B12: Despite a diet that includes meat, factors such as age, certain medications, gastrointestinal conditions (like Crohn's disease or celiac disease), or inadequate intrinsic factor (the protein needed to absorb B12) can hinder absorption.
Next Steps:
- Prepare for Your Appointment: Keep a list of your symptoms, how long they’ve been present, and any other health changes. This will help your physician assess your condition better.
- Understand Possible Testing: Your doctor might recommend additional tests to determine why your B12 levels are low, including checking for intrinsic factor antibodies or performing blood tests to assess red blood cell health.
- Dietary Considerations: While you consume meat, consider integrating other sources of B12, like dairy products and eggs, or B12-fortified foods, until you can confirm your levels and discuss with your doctor.
- Consider Supplementation: If your doctor agrees, you might need B12 supplements, which can be taken as pills, sublingual tablets, or even injections in some cases.

Experiencing Discomfort with a Tight Cast?
On Wednesday, I sustained a fracture to the outer metatarsal bone in my foot, and by Friday, I had been fitted with a cast. While the discomfort at the site of the fracture has diminished, I've been feeling an unusual tingling in my heel, reminiscent of standing on it for an extended period. I haven’t borne any weight on my foot and have frequently kept it elevated. However, I've noticed that my toes display a bluish tint whenever I allow my leg to dangle or even while resting on the knee scooter I’m using. My medical history includes Addison’s disease, thyroid issues, celiac disease, and low bone density.
Experiencing Severe Pain from a Second-Degree Burn: Is This Common?
A week ago, I had an unfortunate incident where I accidentally spilled boiling water on my left calf. The burn formed an oval-shaped patch measuring approximately 8 inches in width and 1 foot in length, nearly encircling my calf. Fortunately, most of the damage appeared to be minor first-degree burns, but I did develop a couple of alarming blisters, each around 1.5 inches wide. I mention that I *had* blisters because they burst around three days after the accident. Initially, I followed the emergency department's advice to cover the burn using cling film, but after the blisters broke, I transitioned to sterile gauze and elastic bandages to minimize the risk of infection. On day five post-injury (which was three days ago), I noticed that the skin on the affected area came off with the dressing during a bandage change. While the discomfort was tolerable during days two to five, it escalated to severe pain once the skin loss occurred. I have been diligent about keeping the wound clean, changing the dressing daily, and sanitizing the area with wound cleaning wipes prior to applying a new bandage. However, I'm beginning to feel anxious. There’s no discoloration or unusual odor, but I’m worried about the effectiveness of the gauze because it seems to remove any scabs my body has formed when I take it off. Still, I am reluctant to leave the wound uncovered due to the potential for infection associated with such a significant injury. A bit about myself: I’m a 19-year-old, standing at 5'7" and weighing around 63 kg. Although I was assigned female at birth, I was later diagnosed with Complete Androgen Insensitivity Syndrome (CAIS), which means genetically I am male. I also have autism, which can influence how I perceive sensory experiences. Currently, I am on lisdexamfetamine dimesylate (known as Vyvanse in the U.S.) and managing the pain with Ibuprofen and Paracetamol. My pain is quite severe, making it difficult to find a comfortable position for sleep, and my focus is entirely consumed by this injury, impacting my work productivity. While I don’t believe it warrants a visit to the emergency department, I find myself at a loss for what to do next. I would really appreciate any advice or recommendations to alleviate my situation.
Concerns About Sinus Issues?
Hello! To give you a bit of background, I’m a 25-year-old female. Interestingly, I've never been able to successfully blow my nose; whenever I try, the air just seems to escape towards my ears or even my eyes. I have no idea why that happens. My sister and I have always thought of it as a quirky trait, but I’m beginning to wonder if there might be a more serious underlying issue. Just today, I brought up that I experience sinus headaches nearly every single day, something that has plagued me for years. She was quick to point out that this isn’t normal. The pain is concentrated right in the middle of my forehead and behind my eyebrows, and it can be incredibly intense. I find myself reaching for Excedrin almost daily to cope with it. Additionally, I should mention that I have dealt with chronic sore throats throughout my life, which we assumed was just an indication that I’m more sensitive than others. It's also worth noting that my doctor isn't very attentive; it took four separate visits before they finally diagnosed me with celiac disease, so I am quite hesitant to return unless I am sure there’s something genuinely wrong that needs addressing.
Seeking Help for Unaddressed Medical Conditions: Navigating Discrimination in Healthcare
I am a 30-year-old male, standing 6'4" and weighing 180 pounds, with a medical history that includes sciatic nerve discomfort, lumbar nerve compression, and PTSD stemming from my past experiences. While this situation may initially appear to be a legal matter related to the Havana Syndrome or the concept of being a Targeted Individual, my primary need is for medical attention regarding my ongoing health issues that seem to be overlooked. Therefore, I'd appreciate any advice focused on securing appropriate healthcare rather than psychiatric commentary. To provide some context, I have been facing a condition often identified with Havana Syndrome for the last five years, a situation that arose following my experiences with sex trafficking. There is substantial documentation from government entities highlighting the seriousness of this issue and its national implications. I recognize that many healthcare providers may not be equipped to address this syndrome due to its varied and often elusive symptoms. Moreover, I classify myself as a Targeted Individual, having experienced what I believe to be harassment through technological means, including suspected use of directed energy weapons and long-range acoustic devices. My symptoms, which echo those associated with Havana Syndrome, include severe brain fog, widespread pain, irregular bleeding from bodily openings, cognitive impairments, sensations of vertigo, breathing difficulties, and other physical damage such as spinal injuries classified as dextroscoliosis or degenerative disc disease, as noted by my doctors. For three years, prior to the identification of any physical issues, I was repeatedly referred to psychiatric services during my visits to various medical professionals and emergency rooms. Whenever I mention Havana Syndrome-like symptoms, the diagnosis often appended is "delusions." This pattern has resulted in my systematic exclusion from pain management options. I am seeking guidance on how to end this discriminatory treatment and find a more acceptable and professionally recognized method of obtaining care. I endure daily pain, and my health condition worsens with time, yet I continue to be labeled as delusional.
Comparing the Effects of Over-Icing and Lidocaine Patches on Severe Foot Pain
Age 39, height 5'5", weight 250 lbs, primarily sedentary lifestyle. For the past month, I have been experiencing intense pain, swelling, and heightened sensitivity in my feet without any clear mechanical explanation. I have a scheduled appointment with my podiatrist in two days, but right now, the bruising is worsening and the discomfort is becoming unbearable. Thus far, the only two remedies that offer some relief are lidocaine patches and ice. However, I have reservations about the lidocaine patches since they do not address the swelling, which raises concerns about potential harm when I attempt to walk a few times daily. On the other hand, I worry that I might be over-using ice, as it has been my primary source of relief throughout this ordeal. I typically utilize a chemical ice pack wrapped in a pillowcase, applying it to my feet, which are covered by cotton socks, for intervals of 5 to 10 minutes. I alternate between feet and vary the positioning, but haven’t been allowing ample time for breaks as I probably should. Here are some additional treatments I've attempted: - I’ve been taking ibuprofen 800 mg three to four times each day; it alleviates some pain, but not fully. I am trying to limit this due to potential health issues. - Elevating my feet has not proven substantially beneficial, as the throbbing discomfort often negates the short-lived relief it provides. - I’ve started using topical diclofenac 1%, switching from ibuprofen; it shows some promise, although it hasn’t matched ibuprofen’s effect yet. - I’m currently using heel cups from Amazon Orthopedics. I also possess metatarsal pads, but I’m hesitant to employ them as I’m uncertain about their correct placement, and wearing both types appears to be too much for my feet. Thank you for any advice or insights you can offer!
