Unexplained Low Phosphate Levels: Seeking Answers
At 37 years of age, I am facing a puzzling health issue. My recent blood tests over the past six months consistently indicate low phosphate levels, yet other related metrics remain normal. My PTH and vitamin D levels are satisfactory, and my kidneys show no signs of dysfunction. Additionally, all other blood parameters appear to be within acceptable ranges. My doctors are genuinely perplexed, as they haven't identified any common indicators typically associated with low phosphate. Recently, I received a 200ml infusion, and I'm scheduled for further blood tests to monitor if my phosphate levels continue to decline. What are some potential underlying causes if the usual suspects—such as thyroid problems, kidney disease, or alcohol use—are ruled out?

Main Points: Consistently low phosphate levels can have several less common causes even when typical factors are ruled out. It's important to focus on monitoring and potential underlying conditions that may not have surfaced in standard tests.
Explanation: Low phosphate levels, or hypophosphatemia, can arise from various factors including dietary inadequacies, absorption issues, excessive excretion due to medications, or certain medical conditions. Since you've already ruled out common issues like kidney dysfunction and thyroid problems, it’s important to consider other underlying causes. Factors such as malnutrition, gastrointestinal conditions (like celiac disease or Crohn's disease), hormonal imbalances, specific medications (like diuretics or some antacids), or chronic conditions could be contributing to low phosphate levels.
Next Steps:
-
Dietary Review: Examine your diet to ensure you are consuming enough phosphate-rich foods. Good sources include dairy products, meat, fish, nuts, and whole grains. Consider keeping a food diary for a week to track your intake.
-
Monitor Symptoms: Keep a journal of any symptoms you might experience alongside the low phosphate levels—such as weakness, bone pain, or fatigue—and report these to your healthcare provider. This can help identify any patterns or correlations.
-
Follow-Up Testing: Keep track of your upcoming blood tests closely. If phosphate levels remain low despite interventions or infusions, discuss with your doctor the possibility of further assessments such as gastrointestinal evaluations to check for absorption issues.
-
Medication Review: Review any medications you're taking to see if they might contribute to phosphate loss. Discuss with your doctor if any changes are needed.
-
Stay Informed: Engage actively with your healthcare team. Let them know about any new developments or concerns. It may also be valuable to ask about seeing a specialist, such as an endocrinologist or a gastroenterologist, if low phosphate persists.
By focusing on these tailored steps, you can start addressing your low phosphate levels proactively. Remember, it’s important to remain patient as your healthcare team works to identify the cause. If you have additional concerns or symptoms, please don't hesitate to reach out.

Mystifying Symptoms: Numbness and a Mysterious Ring on My Neck
I am a 36-year-old male experiencing some perplexing health issues. Initially, I felt pain in my chest, located in the upper left section, near my heart. This sensation then progressed to a tingling, burning numbness on the left side of my neck. Over the past month, I've suffered from two separate incidents of similar symptoms, both emerging quite suddenly. One minute, I feel perfectly fine, and the next, I'm overwhelmed with the fear of a heart attack. To address my concerns, I consulted with a cardiologist who conducted various tests, including an EKG, a stress EKG, and blood tests for CPK, D-Dimer, and Troponin. I later underwent an echocardiogram during my second episode, which affirmed that my heart is functioning well. Normally, my blood pressure is stable, but I experienced elevated readings during both episodes, peaking at 155/80. My resting heart rate is usually between 45 and 50 beats per minute. The initial episode persisted for about a week before the symptoms receded and I returned to a sense of normalcy. I initially suspected that it might stem from a pinched nerve due to my history of neck and back problems, which I have managed over the years, albeit with occasional flare-ups, mainly in my lower back. However, this seemed different from anything I had previously encountered. The second incident transpired unexpectedly on Saturday, June 14th, and presented somewhat differently. While I still experienced minor chest discomfort, the predominant sensation was numbness radiating down the left side of my neck, extending from just beneath my ear down to my collarbone. My heart rate quickened, and although I did not check my blood pressure at the time, it likely surged. I acquired a blood pressure monitor the following day to confirm these changes. To rule out significant heart concerns, I promptly arranged for an echocardiogram. It took a few days to receive the full results, but everything came back normal. In the early days of the second episode, I also noticed a mild nerve pain that shot into my right hand, making computer usage uncomfortable. Thankfully, my symptoms gradually improved over the next few days, though I still experience intermittent tingling and numbness, particularly localized under my jaw, near where the jugular vein runs. During a visit with family last weekend, my mother observed a faint ring beneath my ear, aligning closely with the area where these sensations are centered. The underlying cause of these symptoms remains unclear, but I have gathered some pertinent notes: * I suspect there might be a connection to my intake of medjool dates. I was consuming around ten a day and recently increased my intake, especially with salted peanut butter as a snack. This change occurred in the weeks leading up to the episodes. Though I have regularly eaten them for nearly a year, I may have overdosed on electrolytes or potassium, or possibly experienced an allergic reaction. * I've noticed that my symptoms sometimes worsen right after meals. * While exercising generally has no adverse effects, it seems to provide temporary relief from the symptoms at times. As for medications, I am not currently taking any, but previously used Doxycycline (100 mg/day) intermittently for ongoing skin issues, last taking it about two months ago. In terms of supplements, I was taking 2500 IU of Vitamin D3 four times a week but stopped around a month prior when it was linked to skin issues. I also consumed 8 mg of Zinc daily, as my diet lacks sufficient amounts, and about 900 mg of omega-3 from algae oil daily, which I ceased last week to evaluate any possible contribution to my symptoms. I take 500 mcg of B12 twice daily, although I do not consistently take it and believe it doesn’t play a role in my current situation, as I have been taking it sporadically for years. Regarding substances, I entirely avoided caffeine, alcohol, and vaping or smoking. For years, I regularly consumed THC gummies (up to 100 mg/day) but recently reduced my intake to only weekends, stopping completely around a month ago due to potential correlations with my symptoms. I also used TRE gummies, which contain a blend of nootropics aiming to replicate psilocybin's effects but are relatively mild. A week preceding the second episode, I tried them without issue; however, the night of that episode, I experienced heightened anxiety as my symptoms recurred, leading to a troubling night. While I don’t believe these items caused my symptoms, they could have intensified their emergence. My diet consists of a well-rounded plant-based approach, generally healthy, besides occasional indulgences in trending snacks. I typically balance fruits, vegetables, whole grains, nuts, seeds, and legumes, steering clear of meat, dairy, soda, and processed foods. I also maintain a regular exercise routine that includes cardio and resistance training several times a week, with yoga once a week and daily walks. Notably, during my most recent blood tests, conducted about six months ago, I identified some markers outside the normal range. I have been conducting full health panels biannually since June 2024, with some values showing changes such as elevated RBC (5.84 to 5.66 million/uL) and hematocrit (52.3 to 50.3%). Ferritin was low (18 to 22 ng/mL), prompting dietary changes that increased iron levels substantially (148 to 289 mcg/dL), while iron saturation rose from 41 to 76%. My TSH levels also showed a rising trend (6.36 to 5.82 mIU/L), and there is a family history of thyroid issues, with members currently on medication. Other markers remained within healthy reference ranges. Given all these factors, I find it challenging to pinpoint a diagnosis. My foremost hypothesis suggests either an inflamed nerve or vein, potentially triggered by an unforeseen dietary imbalance or perhaps an allergic or immune response. It is also possible that the ring under my ear is significant; however, it is neither raised, itchy, nor painful when touched—just present. I appreciate anyone who has taken the time to read through my situation. Even if you cannot provide insights, I am grateful for this platform where support is offered to those seeking help.

Seeking Solutions for Persistent Scabs
At 29 years old, I weigh 222 pounds and I'm a non-smoker. I'm currently on medications including Plaquenil, Imuran, and Citalopram, and have been diagnosed with Sjögren's syndrome along with depression and anxiety. For the past six months, I have been taking azathioprine to manage my Sjögren's symptoms. Recently, I experienced a severe breakout that coincided with my menstrual cycle, and I regretfully picked at some of the spots. As a result, I've developed scabs and acne on my upper back, chest, and face. It’s been three weeks, and despite my efforts not to pick at them anymore, these issues refuse to heal. The acne tends to linger for an extended period as well. I consistently moisturize my skin and try to handle it with care, yet I'm looking for ways to enhance the healing process. I'm feeling quite desperate for some advice. I consulted with my rheumatologist, who suggested I reach out to a dermatologist if my condition doesn’t improve; however, I’m facing challenges as dermatology services are not covered under my insurance plan.
Unusual Health Concerns
I’m a 16-year-old female, standing at 163 cm and weighing 75 kg, and I’ve been experiencing some unusual health issues lately that have me quite concerned. Recently, my menstrual cycle, which is typically consistent and heavy, has thrown me for a loop; it was delayed by two weeks this time and has turned exceptionally light. I'm hardly using a regular tampon throughout the day, even during what would generally be my heaviest flow. In addition to this irregularity, I’ve been plagued by a range of other symptoms. Persistent fatigue has become my new normal, and even a full night’s sleep doesn’t seem to help. My ability to concentrate is significantly hindered; I often find myself feeling mentally foggy and depleted. Emotionally, I’ve noticed a shift—I feel more downcast and glum than I typically do, almost like I’m not in my usual emotional state. My cravings have shifted as well; I’m drawn to sugary and carb-rich foods more than ever. Concurrently, my skin has been breaking out considerably. Frequent headaches have become commonplace, I've gained a bit of weight, and overall, it feels like something is off with my body’s equilibrium. I’ve had issues with low iron previously, necessitating an infusion. Currently, I’m prescribed 100 mg of Sertraline and 25 mg of quetiapine. I do not smoke nor partake in recreational drugs. On rare occasions, I drink alcohol—maybe two or three times a year. Honestly, I am puzzled about what’s happening to my body.
Could It Be Tinea Capitis or Something Else?
I have a six-year-old son who is generally in good health and takes no medications. Last night, while I was brushing his hair, I discovered a red patch on his scalp. Initially, I thought the crusty area was simply dried soap residue, so I continued to gently work through it. However, I soon noticed some small tufts of hair began to come out as well. He indicated that it was painful, which led me to stop immediately. Although he mentioned that it feels itchy, I haven’t seen him scratching the spot unusually. I appreciate any insights!
Foul Odor and Discharge from Ear
A 36-year-old woman, with a height of 5 feet 6 inches and an approximate weight of 15 stone, has been grappling with some health issues including endometriosis, adenomyosis, and osteoarthritis, for which she is prescribed sertraline and oxycodone. For an extended period, she has been experiencing a foul-smelling discharge from her ear, a situation that has progressively deteriorated. This individual has also suffered significant hearing loss in the affected ear, a condition that dates back to her childhood. In her earlier years, she underwent various surgical procedures including grommet placements, T-tube insertions, and perforation repairs. Towards the end of the previous year, she consulted an ENT specialist who applied a Vaseline-like treatment to her ear. Unfortunately, she was unable to attend the follow-up appointment since it coincided with a colonoscopy appointment, and she has not received any updates since informing them of her circumstances. Recently, upon waking, she noticed a considerable amount of discharge in her hair, which carries an unpleasant odor reminiscent of a wet dog. Currently, she is uncertain whether the substance on her eardrum resembles a scab or something else entirely.
