Struggling with Chronic Heat Sensitivity
Despite consulting numerous healthcare professionals, I find myself in a frustrating position where no one seems to understand my condition or its implications. I’m reaching out in hopes that someone might have insights or solutions. I am a 30-year-old woman grappling with both mental health issues and chronic pain. While I’m working on managing my weight, I haven't encountered any serious health issues that could account for my current struggles. Notably, these problems have persisted regardless of my body weight fluctuations. Initially, my episodes of heat exhaustion occurred under typical scenarios: hot weather, hiking, or spending time outdoors without sufficient hydration would lead to headaches and nausea. In those early instances, a little water, electrolytes, or applying ice to my wrists would usually suffice. Such occurrences were sporadic, happening only every couple of years. However, the situation has deteriorated over time. I now experience these episodes in much milder temperatures and even short exposure sends my body into turmoil, escalating the intensity of my symptoms. Consequently, I have had to halt my hiking adventures, avoid family trips, and generally confine myself indoors during the warmer months, especially when temperatures exceed 25°C (77°F). I now rely on a water bottle to maintain hydration at all times; failing to do so results in debilitating headaches and nausea—even during winter months. I consume more fluids, including electrolyte beverages, than anyone I know yet find myself hardly needing to urinate. My doctor humorously suggests I must be storing water like a camel, but I don't experience any issues like swelling or excessive sweating, leaving me perplexed about where all this hydration is going. My lowest recorded trigger point for symptoms was 23°C (73°F) during a visit to the zoo. After strolling around for hours with a friend, I ended up needing him to drive me home due to an unbearable headache and extreme nausea, even though I remained conscious. The most severe incident occurred recently at the Calgary Stampede, an outdoor event known for its food vendors. The temperature was a manageable 26°C (79°F) when I attended. After roughly four hours—three of which were spent indoors—I became ill despite having consumed nearly three full metal water bottles. The paramedics had to transport me in a wheelchair and administer an IV, warning me about the potential life-threatening nature of my condition. Now, even seated comfortably in my air-conditioned home, I am wrestling with a headache and nausea that sets in just from existing, light studying, or being inactive. Sadly, my healthcare team remains stumped. A recent visit to an internal medicine specialist yielded no solutions; they merely recommended increasing my salt intake, though I already rely heavily on electrolyte beverages for some relief. Reviewing my medications hasn't illuminated any issues either. The collective symptoms and suggested treatments align closely with heat exhaustion—a situation now bordering on heat stroke. However, I am confounded as to why these symptoms surface at room temperature and so frequently. This is not a sustainable way to live. I hope someone reading this may offer guidance or suggestions as my doctor can't even point me toward a specialist who might provide support.

Main Points: Chronic heat sensitivity can significantly impact your quality of life, especially with episodes occurring at lower temperatures. It’s vital to explore potential causes and management strategies that address your symptoms effectively.
Explanation: Your experiences with chronic heat sensitivity suggest a possible issue with thermoregulation or sensitivity to temperature changes. While it can be frustrating that healthcare providers have not pinpointed a cause, the body can sometimes react unusually to heat due to a variety of reasons, including underlying conditions or autonomic nervous system dysregulation. It’s understandable to feel overwhelmed by the lack of clarity, but there are actionable steps we can take to help manage your symptoms and improve your situation.
Next Steps:
-
Track Your Symptoms: Maintain a detailed diary noting symptoms—when they occur, activities prior to onset, and environmental conditions (temperature, humidity). This data can be invaluable during discussions with healthcare professionals.
-
Environmental Control: Continue using air conditioning and consider thermal wear (light, moisture-wicking clothing) even indoors. You might also explore using cooling products (like vests or towels) during potential heat exposure.
-
Hydration Strategy: As you are already focusing on hydration, consider trying a variety of electrolyte solutions to find one that works best for your body. There are different formulations that might better support your needs.
-
Dietary Adjustments: Although salt intake was recommended, it’s beneficial to balance it with potassium and magnesium, which are crucial for muscle function and may help with your symptoms. Foods like bananas, leafy greens, nuts, and seeds can be included.
-
Gradual Heat Tolerance Training: If possible, engage in gradually controlled exposure to warmer environments, starting from a comfortable temperature for short periods. The goal is to slowly build tolerance, but this should be done cautiously to avoid overwhelming symptoms.
-
Investigate Autonomic Dysfunction: Given your symptoms’ nature, discussing autonomic dysfunction with a new specialist, such as a neurologist or a specialist in autonomic disorders (like POTS or similar conditions), may provide more insight. There are specific tests they can conduct to diagnose related issues.
-
Mind-Body Approaches: Since mental health is a component of your experience, integrating stress management techniques such as mindfulness, meditation, or gentle yoga may help with symptom management and overall well-being.
-
Seek Support: Engage with support groups, either online or local, where others may share similar experiences. This can help you feel less isolated and provide practical tips from others who understand your situation.
Remember, it’s essential to focus on what you can control and to seek out supportive resources as you navigate this challenging condition. Your well-being is paramount, and taking proactive steps can help improve your quality of life. Let me know if you need more details on any of these suggestions.

Using Tranexamic Acid for Managing Heavy Menstrual Bleeding
At 34 years old, I've tried various contraceptive options, including the Jaydess coil, which initially worked well for me for a whole year before I started experiencing constant bleeding. Since I was 12, my periods have been excessively heavy, leading to frequent episodes of severe anemia. In addition to debilitating pain, which I would describe as moderate on some days, I have a number of symptoms related to endometriosis. After multiple referrals and examinations, it was discovered that I have cervical ectropion, though nothing else significant was identified. My gynecologist encouraged me to consider switching to hormonal birth control options like the pill or coil, or even to undergo a hysterectomy—none of which appeal to me. I have concerns about potential side effects that I have experienced before, such as decreased libido, acne outbreaks, and hair thinning. However, I believe the side effects were less pronounced with the Jaydess. I value my natural ovulation process and worry that any hormonal treatment might disrupt it, especially since I experience intense PMS but feel generally good around ovulation. Recently, I visited a hospital for an unrelated issue, and during the consultation, I mentioned that I am currently taking Tranexamic acid. This was recommended by my doctor after I declined hormonal contraceptives. I take two tablets daily for four days out of each month. However, the consultant I spoke with—who wasn't a gynecologist—expressed significant concern over my use of Tranexamic acid. He advised against long-term usage due to potential severe side effects, describing it as a readily available medication for menstrual issues. Now, I find myself anxious about continuing this treatment, yet I am equally afraid of the repercussions of heavy monthly bleeding. Any guidance or advice on managing this situation would be greatly appreciated.
Unexplained Hamstring Muscle Spasms
I am a 29-year-old female with a weight of 51 kg and a height of 167 cm, and I do not have any significant health issues. Recently, for over a month, I have been dealing with uncomfortable spasms in the muscles at the back of both thighs. To clarify, this isn’t the same as a charley horse. My physical activities are limited to occasional yoga, swimming, and dancing—I do not regularly go to the gym, and I can't attribute these spasms to any injuries or physical strains. It all began after I attended a concert where I stood in line for two hours. Initially, I thought the discomfort might be due to fatigue, but as time went on, the spasms persisted. These episodes consist of quick, sharp pains that can affect either leg, prompting me to massage the affected area or sit down. They do not disturb my sleep, nor do they arise during exercise; rather, they tend to occur after sitting for a while or upon getting out of bed in the morning, specifically when I am standing still. Unlike cramps—which I am quite familiar with as they typically affect me at night or occasionally during stretching—these spasms feel different. In an effort to alleviate the situation, I have been increasing my physical activity and focusing on hamstring stretches, yet I have seen no improvement. I consulted a neurologist about my concerns, but the examination yielded no evidence of neurological issues. Additionally, blood tests showed normal levels of electrolytes and a creatine kinase level of 40. Although I do have a herniated disc located higher in my spine (D12-L1), it doesn’t seem to be responsible for my symptoms, particularly since I do not experience any back pain. I am seeking advice on how to proceed, as these sporadic but disruptive spasms continue to affect my daily life, especially in my work as a photographer.
Discomfort at the Pectoralis Major Insertion Point
Hello all, I'm a 24-year-old male weighing 95 kg, and I've been strength training for around two years now. Over the past four months, I've been experiencing discomfort at the attachment of my pectoralis major tendon near my right armpit on the humerus. While I don’t feel any pain at rest, the discomfort resurfaces whenever I perform chest exercises. I'm beginning to think I might be dealing with a form of tendinopathy or tendonitis. I've occasionally tested my condition to check for improvement, but so far, I haven't noticed any significant changes. Recently, I began incorporating BPC-157 into my routine and am cautiously trying to rebuild my chest strength. This involves integrating very light, high-repetition chest exercises into each workout day, ensuring I stay pain-free during these sessions. - Does this seem like it could be a case of tendinopathy? - Has anyone experienced something similar and found an effective way to recover? - What are your thoughts on my strategy of using light loads instead of complete rest? Does it seem reasonable, or should I adjust my approach? I appreciate any insights you can share!
Experiencing Uncontrolled Urination
This is quite an awkward situation for me to share. I’m an 18-year-old female, standing at 5’6” and weighing 140 pounds. I’ve recently begun my journey at college in a dorm setting. (This part is just an aside.) The main reason I’m reaching out is that for the past two weeks, I’ve been facing an unfortunate problem: I've been experiencing episodes of involuntary urination. Every night, around midnight, I find myself waking up with the urgent need to relieve myself, yet I feel completely unable to manage it. This is completely new to me, as I’ve never dealt with this type of issue before. The initial incident caught me off guard. I was rushing to the restroom with an overwhelming urge, but I unfortunately missed the toilet and ended up having an accident on the floor. I cleaned the mess up promptly. Just three days ago, the situation repeated itself. I woke up at midnight once more, desperate to go. However, all the bathrooms were occupied by my dorm mates, so I was left in a difficult position. I attempted to hold it in, but ultimately I couldn’t contain myself any longer and ended up urinating on the carpet. Of course, I cleaned that up as well. And just today, I found myself seated and unintentionally released a small amount of urine. This is really concerning for me since I’ve never encountered this kind of problem before, and I’m anxious it might start happening more often. I don’t have a history of bladder issues, so I’m unsure how to proceed. I would really appreciate any advice or assistance on this matter.
I Need Insight on Bizarre Health Symptoms!
I’m reaching out in hopes of finding some guidance for a troubling health situation I’m facing. I genuinely need some advice. I’m a 20-year-old woman, weighing 240 pounds and standing at 5 feet 4 inches. My only formal diagnoses are Non-Alcoholic Fatty Liver Disease and asthma. I started showing signs of fatty liver when I was 16 and was diagnosed with asthma at 18. My doctor has recommended Vitamin D supplements, but I’ve avoided them because they seem to exacerbate my current issues. I don’t engage in drinking, drug use, or smoking – I assure you. Since the beginning of this year, I’ve been grappling with several distressing symptoms. It all commenced with severe digestive problems. These episodes typically unfold during the night, bringing on nausea, gagging (without vomiting), watery diarrhea, chills, and significant bloating. I often feel incredibly cold at these times, and the fatigue can be overwhelming, as I feel like I’m battling for my well-being. I’ve been brought to tears on those nights, pleading for help. Initially, these occurrences happened about every two weeks, but they’ve now ramped up to nearly weekly episodes. I’ve attempted various medications for relief, but even anti-diarrheals don’t seem to benefit me. I’ve explored natural remedies as well, including numerous vitamins that claim to alleviate stomach discomfort. Leaving my house without medication has become a source of anxiety, as one wrong meal can send my stomach into turmoil. The diarrhea and gas are persistent, and despite knowing that anti-diarrheals may be harmful to my liver, they are my only means of getting any normalcy in my day. I am reaching out to ask if anyone has any ideas about what might be going on with me. My doctors appear to be perplexed by my symptoms, and while I’ve undergone a series of blood tests, nothing definitive has emerged, aside from indications of potential pre-diabetes and signs suggesting my body is fighting something off. I’m desperate for any potential explanations to discuss during my next appointment. I am convinced that something is not right, and while my doctors may not see how much it affects my quality of life, I am keen on finding a solution. Without a coherent theory about my health, I worry they might not take my concerns seriously enough. Thank you very much for taking the time to read my post. I don’t usually share on platforms like this, so I hope I presented my situation clearly. I have an appointment scheduled for tomorrow, and I plan to insist on additional tests to uncover what’s happening. I might provide updates afterward!
