Understanding Phosphate Levels in My Case
Subject: 34-year-old female, 45kg, from the UK. On the 10th and 11th of October 2025, I contracted Covid-19. I experienced flu-like symptoms that lasted for two weeks while I stayed at home. When I tried to return to work, I was met with significant weakness in my legs. Unfortunately, this condition persists, along with other lingering issues from my long Covid diagnosis, and I now require a wheelchair for mobility. What stands out to me are two specific phosphate readings taken just over three weeks apart: **First Reading (I was feeling absolutely terrible):** Phosphate Level on 3rd November: 1.25 mmol/L → within normal limits. **Second Reading (Condition worsened):** I sought treatment in the Accident & Emergency department due to extreme difficulty in walking. The staff informed me that recovery would take time and recommended a multivitamin since my magnesium was somewhat low. However, reviewing my medical notes, I noticed my phosphate level: Phosphate Level on 24th November: 0.68 mmol/L → below normal (hypophosphataemia). I realize that the intricacies of long Covid can be quite complex, yet I can’t help but wonder what these phosphate fluctuations signify for my symptoms. Could there be a connection worth exploring?

Your concerns about phosphate levels and their potential link to your ongoing health issues are valid, especially in the context of recovering from COVID-19 and experiencing long-term symptoms. Let's break this down to provide clarity and actionable steps.
Summary of Main Points
- Fluctuating Phosphate Levels: Your phosphate levels dropped significantly from the beginning of November to late November.
- Possible Symptom Connection: These fluctuations could be related to your muscle weakness and other lingering symptoms from your long COVID diagnosis.
Explanation
Phosphate is an essential mineral that plays a crucial role in energy production, muscle function, and bone health. Normal phosphate levels in adults typically range from about 0.81 to 1.45 mmol/L. Your initial reading in November was normal, but the later drop to 0.68 mmol/L suggests hypophosphatemia, which can cause symptoms like muscle weakness and fatigue. This condition can be influenced by various factors, such as nutritional deficiencies (like magnesium, which you've noted), inflammation from long COVID, or other underlying health conditions.
Next Steps
-
Nutritional Support:
- Focus on maintaining a diet rich in phosphate. Foods that are high in phosphate include dairy products, nuts, seeds, beans, and whole grains.
- Since you mentioned low magnesium levels, consider including magnesium-rich foods like spinach, bananas, and avocados as well. You might also want to follow your healthcare provider's advice regarding any supplementation.
-
Monitor Symptoms:
- Keep a journal of your symptoms, noting when the weakness intensifies or any new symptoms arise. This will help track potential patterns related to your phosphate levels or other nutritional factors.
-
Hydration and Physical Activity:
- Stay well-hydrated as dehydration can impact electrolyte levels, including phosphate. However, if mobility is challenging, focus on gentle range-of-motion exercises as advised by your healthcare team.
-
Follow-Up Testing:
- If your phosphate levels remain concerning or if your symptoms don't improve, discuss with your healthcare provider the possibility of further tests to identify any contributing factors to the hypophosphatemia, especially in the context of your long COVID status.
-
Regular Consultations:
- Keep in touch with your healthcare team regarding your long COVID issues, as they can provide tailored advice and adjust treatments based on ongoing assessments of your health.
Please remember to reach out if you experience additional severe symptoms, such as significant fatigue, severe muscle pain, or changes in mental function. Your health and recovery are paramount, and staying engaged with your medical team will support your journey towards improvement.

This might end up being quite lengthy, so I appreciate your patience in advance. I am a 48-year-old woman, 5 feet 6 inches tall, weighing 95 pounds. Here’s an overview of my medication treatment: I take 25 mg of Adderall daily, 1 mg of Clonazepam as needed, and 100 mg of Seroquel primarily for sleep. Additionally, I hold a medical cannabis card. My two sons have been diagnosed with Alport Syndrome, each having different fathers. Since April 2025, I've been experiencing significant difficulties. Having worked as a registered nurse, I possess a solid understanding of medical diagnostics and the complexity of health conditions. This background prompted me to pay for a commercial genetic test to identify patterns within my family medical history. I do recognize that interpreting genomic data should be approached with caution. Throughout my medical journey, I’ve faced an array of labels including alcoholic, addict, dramatic, bipolar, and attention-seeking, alongside accusations of faking my symptoms or experiencing psychosomatic seizures. I've endured mistreatment during multiple ER visits. My medical history includes consultations with specialists in gastroenterology, cardiology, neurology, neuropsychology, psychiatry, and two different ENTs. I have been transitioning to a new primary care provider, attending therapy and physical therapy, and regularly visiting a chiropractor. Moreover, I have upcoming appointments with pulmonology and rheumatology, and a second referral for genetics due to the lack of thorough documentation in my initial case. Despite consultations with numerous healthcare professionals, I frequently hear that "everything appears normal," and occasionally receive frustrating responses like, "I’m sorry; I’m unsure how to treat this." I can only remain upright for about 5 to 7 minutes before I face severe shortness of breath, bluish discoloration in my toes, and debilitating head pressure. The autonomic storms I experience are truly exhausting. I have been officially diagnosed with: - Connective tissue disease (hypermobile Ehlers-Danlos syndrome), but not through a specialized EDS professional. - Postural Orthostatic Tachycardia Syndrome (POTS). - ADHD and Autism, complicated by masking behaviors. - Gilbert Syndrome, which significantly affects my metabolism of certain drugs. - Bilateral nasal and facial collapse (I seek no cosmetic improvements, merely the ability to breathe). - COL4A4-related basement membrane disease (within the Alport spectrum). I also have a pacemaker due to tachy/brady sick sinus syndrome, although I suspect it’s largely due to autonomic dysregulation. Genetic testing indicates that I have ineffective absorption of B vitamins, mitochondrial disease, and a lack of response to various medications (all SSRIs/SNRIs, intolerance to estrogen, and issues with medications like Remeron and Benadryl). There is much more to my story, but if you belong to a similar community, you can likely empathize with my struggles. I feel like I’ve lost the essence of myself—my nursing career, the custody of my children due to alcohol accusations, my ability to drive, the support of friends and family, and even my clean and well-kept home. Simple tasks like taking a shower now feel monumental. I’ve suffered dental loss due to unconscious jaw grinding, and dentures are intolerable for me. My social life has deteriorated, affecting my enjoyment with food-centered gatherings and beyond. The trust I once had in the healthcare system is shattered, leaving me questioning my self-worth as my opinions seem disregarded. Since April, I have suffered 33% atrophy of my pancreas and now also have a pancreatic cyst. I do not consume alcohol or other drugs. I find myself immobile in bed, feeling trapped in a reality where my body fails to cooperate and my mind races uncontrollably—a prison, both mentally and physically. What steps can I take to improve my situation? During a recent POTS evaluation, when I experienced a drop, the staff insinuated I was feigning my symptoms since I remained aware of what was happening. It seems there’s a hesitancy among healthcare providers to alter my medical records, despite the dire circumstances. If I experience the humiliating act of ammonia being waved in front of me again—dismissed as a waste of time—I believe I may reach my breaking point. I am highly aware of my non-epileptic condition, so an EEG is not necessary. It’s a misconception that I have comprehensive insurance coverage. Even if insurance were not an issue, I deserve to be treated with compassion, like family. I may be petite and lacking teeth, but I am not struggling with substance abuse. Dentures trigger feelings of choking and suffocation. Also, I wonder when doctors and nurse practitioners stopped conducting thorough assessments and physical examinations. Reviewing past medical notes reveals they often fabricated data regarding my condition. How do they ascertain my abdomen is normal without even examining it? I encounter this issue repeatedly. What phrase or strategy successfully grabs the attention of ER staff when urgently needing care? I have avoided emergency rooms recently due to past experiences, yet if compelled to return, I need effective ways to communicate my critical situation. I have a neurology appointment scheduled for March, yet I worry that after enduring prolonged episodes, I may struggle to communicate my health narrative coherently. I want to ensure I convey the entirety of my medical history to avoid missing vital details. Many concerns are weighing on me, with the facial collapse and chronic breathing difficulties taking precedence. The ordeal of navigating daily life—managing physical space and the constant fear of falling—is overwhelming. Despite increasing my fluid and protein intake, wearing compression garments, and pacing my movements, I find the situation unmanageable. The looming fear of being disbelieved or dismissed adds to my already heavy burden. Additionally, I am struggling to find a case manager or care coordinator to assist me. If anyone can offer support or advice, I would be extremely grateful. I’m located in Kentucky.
Concern About Unusual Sounds in My Neck
At 32 years old, I am grappling with several health concerns stemming from a mild traumatic brain injury (mtbi) I sustained in 2009. Though I have been diagnosed with nerve damage, I continue to experience a range of troubling symptoms, including frequent migraines, sensitivity to light, persistent headaches, a diminished sense of smell, and bouts of unsteadiness when walking. I particularly experience dizziness upon standing, accompanied by a rapid heartbeat. Furthermore, upon lying down or stretching, I sometimes perceive a strange liquid-like sound at the base of my skull, reminiscent of a syringe being emptied, rather than a rhythmic pulsing. Additionally, I deal with ongoing discomfort in my neck and shoulders. I’m attempting to avoid self-diagnosing via the internet, but these symptoms are becoming increasingly concerning. Recently, I consulted with my primary care physician, who performed a brief neurological examination and reported no alarming signs. I find it challenging to articulate my physical sensations and overall body awareness, making it difficult to seek clarity regarding my condition. I'd greatly appreciate any insights or suggestions regarding the noise I’m hearing and whether it might relate to my existing symptoms. Thank you in advance for your assistance!
Understanding Uncontrollable Hand Movements
For the past three days, I’ve been experiencing an unusual twitch in my hand. I’m currently taking Venlafaxine, and up until now, I haven’t encountered any side effects from it, nor do I have issues with my ketamine usage. This twitch is quite bothersome and has left me curious about its cause. Whenever I raise my hand, I notice that either my thumb or index finger moves without my control, which adds to the peculiarity of the situation. What could be happening?
Concerns Surrounding Recent Liver Ultrasound Results
As a 26-year-old woman, I recently underwent both abdominal and pelvic ultrasounds. The following day, I had a consultation with my doctor due to some unusual findings related to my liver. The ultrasound revealed mild fatty infiltration, indicating that while the liver remains a normal size, the radiologist also identified two nonspecific hypoechoic lesions, measuring 3.7 x 3.6 x 2.7 cm and 1.9 x 1.5 x 1.9 cm, respectively. The report emphasized that malignancy should be considered and recommended a multiphase abdominal CT for further assessment. The findings feel quite ambiguous to me, as there wasn't much elaboration on the liver's condition beyond the existence of these lesions. My blood tests—including ferritin, ALT, ALK, and bilirubin—are all within normal ranges, without any elevations, and the ultrasound report did not raise concerns about any other areas. This situation has caused significant anxiety for us regarding what these results indicate. For background, I was diagnosed with breast cancer in 2021, underwent a mastectomy, received radiation, and continue to take mar-letrozole. The urgency of the ultrasound report has prompted us to seek a CT scan through the hospital at the earliest opportunity, in light of my medical history and various other considerations. If anyone has knowledge or insights regarding the implications of these ultrasound results, it would be greatly appreciated. Should we be alarmed about the potential for recurrence or the possibility of metastases? My latest blood levels are as follows: Ferritin: 149 ug/L ALK: 105 U/L ALT: 26 U/L Bilirubin: 15 umol/L
Am I Experiencing Serious Symptoms or Just a Common Cold?
(F20) As someone who tends to worry excessively about their health, I’ve taken to researching my ailments and now I’m convinced I might be facing heart-related problems. Could someone please let me know if I’m overreacting or if it’s time to see a doctor? My symptoms have persisted since this morning; I’m dealing with chest discomfort, a sensation as though my lungs can’t fully breathe, a runny nose, a painful and burning throat, pulsating sounds in my ears accompanied by intense ear pain, muscle aches, fever, and occasional heart palpitations. Typically, my threshold for pain is quite high, and I usually manage common colds without issue, but this level of discomfort is concerning. Is this simply a cold or something more serious?
