Understanding Muscle Fasciculations Linked to Vitamin D Shortage
Is it common knowledge among medical professionals that a deficiency in vitamin D may lead to widespread muscle fasciculations and a range of complex symptoms? In a study published in Acta Clinica Belgica, it has been suggested that vitamin D deficiency can indeed present in such ways, revealing its serious implications. For nearly three years, I (21 years old, 181 cm tall, weighing 64 kg) have been grappling with this condition. Throughout this time, I have consulted approximately 20 healthcare providers, yet none have offered effective solutions. Their suggestions have varied, including ideas about magnesium deficiency and possible neurological disorders. Recently, I initiated a vitamin D supplementation regimen, and I have already noticed a considerable decrease in muscle twitches, cramps, and overall fatigue. Despite my vitamin D levels being measured at 28 ng/ml—which isn’t critically low—I’m curious whether this deficiency could still be the culprit. Are there specific groups of patients who might be particularly vulnerable to vitamin D insufficiency? My symptoms extend beyond just muscle fasciculations; I have experienced chronic weakness, a decline in muscle mass, and a higher tendency for fungal infections, among other issues.

It's great to hear that you've started vitamin D supplementation and noticed some improvement in your symptoms. Vitamin D does play a significant role in muscle function and can indeed be connected to muscle fasciculations and other symptoms you’re experiencing, even if your levels are not critically low.
Explanation
Vitamin D is essential for maintaining healthy muscles and bones. While a level of 28 ng/ml is not considered severely deficient (the generally accepted minimum is around 20 ng/ml), some individuals may still experience symptoms at this level, especially if they have other contributing factors or conditions. Your described symptoms, including muscle weakness and fasciculations, can be associated with insufficient vitamin D alongside a variety of other factors. Chronic muscle issues and susceptibility to infections can sometimes correlate with low vitamin D levels, particularly during times of limited sun exposure, poor dietary intake, or underlying health conditions affecting absorption.
Next Steps
-
Continue Vitamin D Supplementation: Since you’ve noticed improvement, maintain your current vitamin D regime. Standard doses usually range from 800 to 2000 IU daily, but the most effective dose can vary, so ensure you’re following the regimen suggested by a healthcare professional.
-
Dietary Sources: Supplement your intake with vitamin D-rich foods such as fatty fish (like salmon and mackerel), fortified dairy products, and egg yolks. This can help increase your levels more sustainably.
-
Regular Monitoring: Schedule regular check-ups to monitor your vitamin D levels. Discuss with your provider the possibility of checking other vitamin and mineral levels, like magnesium, which can affect muscle function as well.
-
Complete Health Assessment: Given your extended experience with symptoms and consultations, consider a comprehensive review of your health with a provider knowledgeable in functional medicine or an endocrinologist. This can help assess other potential underlying causes contributing to your muscle symptoms, including thyroid function or neurological conditions, even if previous consultations did not yield results.
-
Lifestyle Adjustments: Ensure you are getting enough sunshine exposure where possible, as this can naturally boost your vitamin D levels. Regular exercise, particularly strength training, can also help improve your muscle mass and combat feelings of weakness.
-
Symptom Tracking: Keep a symptom diary, noting any changes in your muscle symptoms, energy levels, and overall health as you continue vitamin D supplementation. This can provide valuable information for any healthcare provider about your condition.
If symptoms persist or worsen, particularly if you develop new symptoms, it's essential to seek out further medical evaluation. Your proactive approach is commendable, and addressing your health holistically will help you find the most appropriate solutions.

Is It Normal to Experience This Level of Twitching?
(20 Male) Over the last two days, I've been experiencing some twitching sensations in the rear of my thighs, particularly while I'm at rest or reclining. Yesterday, it was predominantly in my right thigh, but today it has shifted to the left one. I understand that muscle twitching is often benign; however, my left thigh has been having continuous twitches for about 40 minutes now, making it difficult for me to fall asleep. Strangely, when I place my hand on the back of my thigh, I can't sense the twitching through my palm, yet the sensation persists in my thigh itself. Does this make sense? Am I just being overly anxious about this, or is there a reason for concern?
Identifying the Cause of Widespread Red Spots on My Skin
As a 27-year-old woman, I have experienced the presence of numerous small red spots on my skin since childhood. These dots vary in size from tiny pinpricks to larger patches and predominantly appear on my arms. However, for the past three years, I have also been grappling with a range of health issues that remain unresolved despite various medical consultations. Aside from being diagnosed with hypothyroidism and deficiencies in vitamins D and B, as well as a non-anemic iron deficiency, I suspect that there may be an underlying autoimmune condition at play. My attempts to discuss these concerns with healthcare professionals have often left me feeling frustrated and overwhelmed. In the last year, the quantity of these red dots has increased significantly, spreading to areas where they were previously absent, such as my stomach and the backs of my hands. They have also become more pronounced on my chest and thighs, giving me reason to worry, especially since I only have a couple of confirmed cherry angiomas. Although three different doctors, including a dermatologist, have reassured me that these spots are harmless capillary marks, I cannot shake the feeling that the sudden escalation in their number is not mere coincidence. Whenever I research this issue, I find others with similar spots have far fewer than I do. To provide additional context, here is a summary of my chronic symptoms: I regularly experience mild dizziness, visual disturbances known as visual snow, persistent fatigue, and severe brain fog, which at times affects my speech to the point of reversing words or stuttering. I also suffer from muscle weakness paired with internal tremors during physical activity, frequent headaches, episodes in which it feels as though my body is shutting down, shortness of breath, and various sensations including tingling, burning, and intense sharp pains. Other complaints include deep muscle soreness, random stabbing pains, sensations akin to the flu on my skin, difficulties swallowing, gastroesophageal reflux disease (GERD), discomfort in my upper left abdomen, bloating, food sensitivities, anxiety, insomnia, and instances of waking up with a racing heart. I intended to include a picture for reference, but I am currently unable to do so. I appreciate your time and hope for any insights or guidance based on this description!
Should I Seek Medical Attention After Fainting?
I’m a 31-year-old woman, who doesn’t smoke tobacco but drinks occasionally, about once every couple of months. Earlier this year, I was diagnosed with hyperthyroidism and have been taking propranolol and propylthiouracil for roughly two months. Recently, something alarming occurred for the first time, which deeply concerned both my wife and me. It happened about five hours ago. Last night, we enjoyed some vodka cocktails, and when I woke up today, I felt the effects of a hangover. At one point, I decided to head to the store for some ginger ale. It was particularly hot outside, and I often struggle with heat due to my hyperthyroidism. Despite this, I pushed through. As I walked home—a trip that only takes about five minutes—I began to experience chest pain and dizziness. Once I got upstairs to our apartment on the second floor, I asked my wife to let me in because I was feeling quite unwell. As soon as she opened the door, I collapsed on the floor. I was reportedly stiff, with my eyes wide open and trembling slightly, though I have no memory of this episode. When I regained consciousness, I felt extremely nauseous and rushed to the bathroom. I continue to feel dizzy, but the chest pain has subsided. I still have a minor headache, but thankfully, my wife managed to catch me as I fell, so I didn’t hit my head hard. After the incident, I felt utterly exhausted and took a nap that lasted several hours. Additionally, I wanted to mention that I mistakenly skipped my medication yesterday, which might have contributed to my current condition. After the fainting episode, my blood pressure measured 144/85, which seemed elevated. My question is: should I seek emergency medical care, or could this be attributed to heatstroke? I believe it might be the latter, but considering my hyperthyroidism and my wife's observation of me trembling, I'm uncertain. I plan to wait a few hours to see if the dizziness persists before making a decision, but I would appreciate any insights about my situation. Thank you.
Understanding the Side Effects of Dexamethasone Injection
Hello everyone, I’m a 34-year-old female and I occasionally smoke and drink, about once per week. I’m generally healthy, without any known medications or existing health issues, but I recently experienced my first illness in a long time. Over the last few days, I've been dealing with a variety of symptoms including a coughing fit, nasal congestion, body stiffness, headaches, and sinus problems. This morning, I visited urgent care for assistance. They tested me for the flu, COVID-19, and strep throat, all of which came back negative. They did note that there was some fluid in both of my ears, and understandably, my blood pressure was elevated due to feeling unwell and the anxiety of being at the doctor's office. The diagnosis revealed that I had a viral infection. I was prescribed some medications to pick up later and received a steroid injection before leaving the facility. The steroid they administered was Dexamethasone, a medication I had never used before, mainly because I don’t usually fall ill. For most of the day following the shot, I felt relatively okay — still unwell, but manageable. Tiredness has set in mainly because my sleep has been disrupted throughout my sickness. However, a couple of hours ago, I began to experience nausea and my anxiety spiked. My heart rate typically falls between 68-72 bpm at rest and may rise to 72-85 bpm when I’m not feeling well, but it soared to 104 bpm this time. While I’m experiencing slightly less anxiety now than earlier, my heart rate remains elevated. Has anyone else experienced similar reactions? What side effects did you encounter, and how did you manage to calm down? How long did it take before you felt back to normal? I appreciate any insights or advice!
Struggling with Vascular Health: A Call for Help
Situation Overview: I am a 31-year-old woman, a survivor of two deep vein thrombosis (DVT) incidents, which first required intensive care when I was just 18 years old. Diagnosed with protein S deficiency and an MTHFR mutation, I am currently prescribed Xarelto 20mg indefinitely. I want to clarify that I am confident I am not experiencing a new clot, as I have no symptoms such as warmth or discoloration. My intuition tells me I might be dealing with post-thrombotic syndrome (PTS), chronic venous insufficiency (CVI), chronic inflammation, or lymphedema. However, I lack a definitive diagnosis because medical professionals seem to overlook my concerns. After waiting six months to see a specialist in veins, I left the appointment feeling insignificant; the doctor barely acknowledged my pain because there were no visible signs of distress. Despite being energetic, maintaining a healthy diet, and exercising regularly, my pleas for help were met with indifference. I am exhausted by the repeated advice to simply elevate my legs and wear compression garments. I already practice that faithfully! I engage in manual lymphatic drainage, my husband helps relieve the tension in my legs, I take intermittent walks, and I try various wellness techniques like dry brushing. I’m pleading for a solution to ease my discomfort, which has led to panic attacks fueled by my fear of developing another clot. My symptoms consist of persistent swelling and inflammation, particularly around my knees and between my ankles and calves, where my skin feels hard to the touch. I experience extensive bruising across my legs, intense pain radiating from my feet to my calves, episodes of low blood pressure and dizziness, brain fog, and chronic fatigue. It's unclear whether the fatigue and mental fog are connected. Sometimes my body demands I rest and elevate my feet, yet I know I should maintain my activity level, creating a vicious cycle. I used to enjoy hiking, but the pain has made it impossible. The thought of enduring this ongoing struggle has me willing to sacrifice my savings for some relief and a return to normalcy. Unfortunately, the compression and elevation methods provide only minimal, temporary comfort. Are there any supplements I can safely take alongside Xarelto? Do I really have to endure another long month until my next appointment with a vein specialist? I'm terrified that I will encounter yet another professional who disregards my experiences. I feel lost and desperately need guidance.
