Mystery of a Disappearing Fever After Collapse
I'm not entirely certain if this is the right platform for sharing, but I'm intrigued about an experience I had in the past. At 46 years old, I live with a congenital heart condition that results in a reduced ejection fraction and sporadic episodes of atrial fibrillation, often accompanied by an elevated heart rate. These occurrences are generally managed with Amiodarone, although they do sometimes persist. A couple of years back, I contracted influenza (the test confirmed it was influenza A) and experienced a significant fever, hitting 39.5°C (about 102.5°F), despite taking paracetamol. I believe this situation may have triggered a spell of atrial fibrillation. I didn’t fully grasp the severity of my condition and contemplated asking a neighbor for a ride to the hospital. While I was getting my belongings ready, I quickly realized that I was feeling too weak to walk around, prompting me to lie down on the couch for a moment. The next thing I remember is waking up on the floor next to the couch, feeling utterly dreadful and discovering that I had lost control of my bladder. I finally acknowledged the urgency of the situation and dialed for emergency help. The ambulance arrived remarkably quickly—within about five minutes. The paramedics took my vital signs and observed that my temperature had plummeted, registering below 36°C (approximately 96.8°F). They confirmed this result several times with different thermometers. The ambulance nurse promptly decided that I needed to be transported to the hospital. En route, I experienced nausea and vomited, which surprisingly restored my heart to a normal sinus rhythm. Upon arrival at the hospital, my temperature had slightly improved but still remained under 37°C (98.6°F). After undergoing some assessments and several hours of observation, I was discharged. Once I returned home, I monitored my temperature, which, over the next few days, never exceeded 37.5°C (99.5°F). This leads me to wonder: what happened to my fever? While I understand that the collapse may have resulted in a drop in temperature, I am puzzled as to why it did not rebound afterward. Surely the influenza virus could not have vanished without a trace?

Your experience with the sudden drop in fever and subsequent events following your influenza infection is understandably concerning and complex. Here’s an overview of the main points regarding your scenario:
-
Fever Fluctuations: It’s not uncommon for fevers to fluctuate, especially with viral infections. Factors like body temperature regulation, hydration status, and other physiological responses can influence fever patterns.
-
Potential Explanations for Your Symptoms:
- Vasodilation: When you experienced nausea and collapsed, your body might have undergone vasodilation (widening of blood vessels), which can lead to a rapid drop in temperature as blood flow is redirected.
- Body Cooling: Immobility or lying still can contribute to a temporary decrease in body temperature, especially in a state of stress such as infection.
- Viral Clearance: While it may seem unusual for the influenza virus to vanish quickly, many viral infections can have a rapid course, and your immune system might have effectively cleared the virus.
-
Normalization of Heart Rhythm: The vomiting episode, which coincided with your heart reverting to a normal rhythm, suggests that the physical act of vomiting might have engaged your autonomic nervous system, helping to restore your heart's rhythm. Stressful episodes like dizziness and nausea can trigger a response in your body that affects heart activity.
Next Steps:
-
Monitor Your Health: Continue observing any symptoms you might have, particularly signs of fever, heart rate irregularities, or increased shortness of breath. Note any patterns or triggers.
-
Stay Hydrated: Ensure you are drinking enough fluids, especially since fever and vomiting can lead to dehydration, which may worsen your heart function.
-
Manage Medical Conditions: Continue your prescribed medications, such as Amiodarone, and discuss any concerns regarding your heart condition with your healthcare provider.
-
Follow-Up: Consider scheduling a follow-up appointment with your cardiologist. Discuss your experience, how your heart managed during the illness, and any necessary adjustments to your treatment plan.
It's great that you're seeking to understand your body better and asking important questions about your health. Always feel encouraged to reach out to healthcare professionals for in-depth discussions about these experiences. Your health is important, and understanding these episodes can significantly impact your ongoing care.

Experiencing Pain During Blood Draws
I've never really dealt with irrational fears. Generally, whatever has scared me hasn't been significant, so it's not as if I have an intense fear of medical procedures or drawing blood. When it comes to the needle, my experience has usually been that it doesn't hurt much at all; in fact, I've been complimented on my veins by various phlebotomists. However, the tourniquet presents a different story. It’s surprisingly uncomfortable, and although I don’t have high blood pressure, the pain from blood pressure cuffs is notable enough that I try to overlook it. The pain I feel can be likened to that annoying throbbing sensation after stubbing my toe hard—it's definitely intense. I’ve never been utterly terrified by needles or doctors, just a slight twinge of anxiety when the discomfort becomes extreme. My threshold for pain is quite low, and although I cope admirably, the persistent discomfort is wearing. Once the machine starts or the tube is attached for the vacuum effect, that’s when the experience peaks in pain. It's as if every part of my body feels it simultaneously, with the sensation particularly concentrated around the needle site. Despite my attempts at distraction—closing my eyes, blasting my favorite tunes, or wandering off in a daydream—nothing can truly divert my attention from the pain, which I can feel the exact moment it begins and ends, regardless of my efforts to zone out. As a child, I used to resist procedures fiercely, often requiring restraint and losing myself to tears in a dramatic fashion. It’s embarrassing to recall, but I was never one to exhibit such extreme reactions without cause. Unfortunately, doctors tend to believe that I’m being oversensitive. After each blood draw, I feel the effects dragging on for the rest of the day. While I’ve never fainted, I have experienced prolonged paleness, fatigue, and sometimes I find it difficult to move my arm for the entire day or even into the next. Technically, I am capable of moving it, but the pain I endure often overshadows lesser discomforts I’ve experienced. My history includes a bout with kidney stones, among other unpleasant medical situations. While I deal with additional symptoms, it's challenging to cover everything in this post, but I’m curious why it seems like I am uniquely experiencing this level of discomfort during blood draws. At 18 years old, I’ve just received a diagnosis of high cholesterol, prompting me to modify my diet and increase my physical activity. People often describe me as physically fit, and my weight currently fluctuates around 148 pounds, though it has varied significantly over the years, including a highest weight of 213. I also live with polycystic ovary syndrome, which contributes to my other challenges—enormous pain sensitivity, easy bruising, fatigue, and consistent random aches make life difficult. I often find myself managing a persistent level of pain, typically around a 6 or 7, with anything above an 8 pushing me into intense reactions like screaming or thrashing about. To put it into perspective, I rate blood draws as a solid 5 on good days and as high as 8 during particularly difficult experiences. Additionally, my family has a history of type 2 diabetes, high cholesterol, hypertension, and heart disease. I am actively trying to mitigate these risks by taking positive health steps. Irregular heartbeats have also plagued me, and although my doctor attributes this to high cholesterol, I've experienced them long before any diagnosis. From my early years as a plump infant to hitting a peak at 213 pounds before I was 12 and later slimming down to 148 by age 18, my weight has seen dramatic shifts. My exposure to drugs has been limited to experimental use—I've tried many substances, including LSD, but nothing has impacted me long-term except for a couple of them. On special occasions, I'll enjoy champagne with family, and while I drank a bit more during a breakup at 16, I've never developed a tolerance; my inexperience led to a few regrettable outings. When it comes to THC, it’s been my go-to relief for chronic insomnia and pain. My usage has been sporadic; I often turn to edibles and have never developed a cough from smoking. Instead, when I’d build up a tolerance, I made a habit of taking breaks to reset. There's a lot I manage with my health, and it can be daunting trying to present a complete picture, but I felt compelled to discuss the discomfort I always encounter during blood draws as I prepare for my next one soon.
Seeking Guidance on Adrenal Testing: Request for a Second Opinion
Greetings, I’m a 32-year-old female (standing at 5'9" and weighing 240 lbs) facing a rather intricate medical situation. For many years, beginning around age 16, I have been struggling with severe daytime drowsiness. Additionally, I deal with hyperhidrosis and an intolerance to heat, which significantly hampers my ability to perform even simple tasks, despite being in a controlled temperature environment. I am committed to managing my weight and have sought further evaluations for these challenges, which seem to become more pronounced as I age. My current diagnoses include: dormant vitiligo, mild sleep apnea (managed with CPAP due to anatomical features of my mouth and throat), familial hypercholesterolemia, hypothyroidism, gastroesophageal reflux disease (GERD), insulin resistance, ADHD, and bipolar disorder type 1. There are several conditions under investigation at this time. A rheumatologist is monitoring me for unusual serological results (positive ANA and rheumatoid factor), though I do not fulfill the criteria for any autoimmune condition at present. He suspects possible fibromyalgia or very early signs of rheumatoid arthritis. For neck discomfort, I am receiving physical therapy, evaluated by my doctor of physical therapy, who believes it may result from cervical instability and possible arthritis. I am scheduled to see a spine specialist soon, having been referred by a hand surgeon evaluating a prior traumatic injury to my right index finger resulting in extensor tendon subluxation. As a first step in treatment, I’ll be fitted with a splint. The hand surgeon mentioned that given my rheumatological findings, even though not formally diagnosed, it is common for individuals with autoimmune diseases to experience neck arthritis and tendon problems. I also exhibit hypermobility in my neck, shoulders (extremely), elbows, and thumbs, although I do not meet the criteria for Ehlers-Danlos syndrome (EDS). I have concerns regarding my endocrinology appointment after my psychiatrist recommended I see a specialist due to attempts to adjust my stimulant medication to potentially alleviate my hyperhidrosis. My medication and supplement regimen currently consists of: lithium, levothyroxine, lamotrigine, Protonix (a proton pump inhibitor), metformin, MyDayis (a stimulant), low-dose aspirin, spironolactone/minoxidil for hair treatment, vitamin D3/K2, krill oil, CoQ10, and myo-inositol/d-chiro inositol. During my visit, the endocrinologist only conducted a cortisol test using dexamethasone suppression, revealing a result of 1.9, which she classified as normal. However, during my research, I discovered that cortisol levels above 1.8 could suggest a possibility of subclinical hypercortisolism. At the appointment, the endocrinologist speculated that I may be excessively producing adrenaline, contributing to my heat intolerance and sweating issues. Despite this, she declined to order tests for 5HIAA or metanephrines due to my medication. She stated that I would need to discontinue my stimulant for six weeks to proceed with those tests. I clarified that my stimulant use is not solely for ADHD but is necessary to maintain alertness during the day. My pulmonologist has informally diagnosed me with idiopathic hypersomnia after a failed attempt to test for narcolepsy type 2, since my sleep didn't meet the necessary criteria for the second phase of the evaluation. Additionally, I am not a candidate for Xywav due to interactions with my medications. Given these circumstances, the endocrinologist concluded that another sleep study would not be a worthwhile investment of my resources, considering I wouldn't be able to modify my treatment. In researching these stimulant interactions further, I found that a 72-hour pause could be more suitable for testing, rather than her six-week recommendation. The endocrinologist has invited me to collaborate with my psychiatrist to explore potential alternative medications that wouldn’t interfere with testing. My psychiatrist proposed transitioning to Provigil or Nuvigil as a temporary substitute for MyDayis. I’m reluctant to alter my medication for two months, especially without convincing evidence necessitating such a change. Moreover, taking two months off from work and daily responsibilities to sleep around the clock is not manageable. This entire experience with the endocrinologist has left me feeling somewhat disheartened. Thus, I am considering whether seeking a second opinion regarding potential adrenal issues would be beneficial.
Managing Sinusitis After a Flu Experience
Recently, I transitioned from a hot climate to a colder city after spending three years in the former. While exploring this new city on my scooter, I was frequently exposed to dust, which seems to have taken a toll on my health. Over the last two weeks, I’ve been experiencing symptoms such as chest congestion, gastric discomfort, and shortness of breath. I consulted with a well-regarded hospital in the area, where I was prescribed the following medications: - Sompraz (for gastric issues) - Ebast DC - Pulmoclear - Fluticone OZ nasal spray I’m curious about the potential side effects of these medications and whether this treatment is sufficient for my recovery. Additionally, I would appreciate recommendations on suitable foods to consume during this time. Should I also limit my outdoor activities? For context, I am 21 years old and have never smoked or consumed alcohol.
Experiencing Monthly Flu: Is It Common?
At 24 years old, I'm a female resident of the Philippines, and I find myself battling the flu on a monthly basis. This recurring illness raises the question of whether it's something to be concerned about. Each month, it feels as though my immune system takes a significant hit. In an effort to stay healthy, I consistently take vitamins and make it a point to work out during the weekends. Additionally, I prioritize consuming whole foods in my diet. Is this frequency of illness typical? I'm seeking guidance and am considering getting vaccinated against the flu.
Concerns About Possible Kidney Infection After UTI Treatment
I’m a 21-year-old female, standing at 5’1" and weighing 190 pounds. At present, I am on a regimen that includes macrobid at a dosage of 100 mg and lexapro at 10 mg, which I have been taking for the past four years. Last Sunday, I received a diagnosis of a urinary tract infection (UTI). My symptoms had begun the previous Thursday, initially leading me to believe that I was just experiencing some discomfort due to a bruised cervix. However, once I started noticing blood in my urine on Sunday, I decided to visit my doctor, who confirmed the UTI. At that point, I was not experiencing any pain in my back. I began treatment with bactrim shortly after the doctor's visit, but due to a mild allergic reaction, I switched to macrobid the following day, which was Monday. Today, I’m feeling quite unwell—experiencing a headache and general body discomfort. After work, I rested for a bit and awoke feeling extremely fatigued, as if I had been run over by a truck. My body aches persist, I’m slightly dizzy, and the headache remains. Additionally, my nose is congested and running, and I’m battling nausea and a diminished appetite. I suspect I might have a low-grade fever as well. I managed to eat dinner, albeit with some effort, and took my third dose of macrobid along with ibuprofen for the headache. While the headache has improved somewhat, I still don’t feel good overall, and I have a mild ache in my lower back. Interestingly, most of my UTI symptoms have subsided—my urine appears normal, and I no longer experience urgency or discomfort. However, I am now left feeling ill. I’m beginning to question whether these sensations are side effects of the antibiotic or if I might be developing a kidney infection instead.
