Exploring the Neurological Insights on Post-Viral Dysautonomia Following Influenza B
Hello everyone, I am reaching out to gather insights from professionals knowledgeable in neurology or autonomic systems. Although post-viral discussions often highlight COVID-19, my experience stems from contracting Influenza B. My neurologist notes that my symptoms bear a resemblance to the post-viral dysautonomia observed in long-COVID cases. I am eager to know if the progression and types of symptoms I’ve experienced resonate with those familiar with disorders related to autonomic dysfunction. **Background Information** - I have suffered from POTS (Postural Orthostatic Tachycardia Syndrome) for approximately 15 years, and it had been relatively stable and manageable prior to my illness. - Following an Influenza B infection in June, I developed a new syndrome that is markedly different from my usual POTS symptoms. From about August through early October, I encountered significant sympathetic overactivity which manifested as follows: - A constant state of fight-or-flight response - Episodes of hyperadrenergic "rushes" - Flushing episodes affecting my face and ears - Internal feelings of unrest - Uncontrollable fluctuations in emotions - Severe nausea and lack of appetite - Difficulty transitioning to a more relaxed, parasympathetic state. This experience felt more like a breakdown of autonomic regulation rather than primary anxiety, considering my background as a clinical psychologist. **Description of Hyperadrenergic Episodes** These episodes are characterized by: - Sudden facial flushing - Piloerection or goosebumps - Prickling or tingling sensations - A heightened state similar to an adrenaline rush. Over approximately eight months: - The intensity of these episodes has diminished - The duration of each episode has shortened - A number of the episodes now terminate before fully developing. My neurologist believes this reflects an improvement in autonomic inhibitory control. **Proposed Neurological Framework (according to my neurologist)** - Post-viral autonomic dysfunction, likely involving brainstem regulatory systems. - There might be a neuroinflammatory or immune-mediated insult impacting the integration of autonomic functions. - A consistent pattern of morning activation suggests a disturbance in autonomic circadian regulation. **Prognosis Based on Symptom Progression** - Evidence points to gradual improvement - A slow resolution is anticipated rather than irreversible changes - A phased return to baseline functioning is expected within about 6 to 8 weeks - Near baseline recovery is projected around one year post-infection. **Current Symptoms** - Ongoing nausea coupled with a reduced appetite (this remains my most prominent issue) - Morning episodes of autonomic activation and arousal - Fluctuating states between heightened sympathetic activity and shutdown with nausea - Showers of goosebumps or chills throughout the day - Occasional flushing episodes - Eyelid twitching or myokymia - Hypnic jerks at sleep onset (though improved, they are still occurring). It's noteworthy that I have not experienced significant fatigue or post-exertional malaise (PEM). **Inquiries** I would appreciate input from individuals with expertise in neurology or autonomic dysfunction: 1. Does this symptom trajectory resonate with the concept of post-viral autonomic recalibration or brainstem dysregulation as one recovers? 2. Is the transition from fully hyperadrenergic episodes to those that are partially aborted indicative of the restoration of autonomic control pathways? 3. Are the symptoms of goosebumps, flushing, and eyelid twitching reasonable signs of sympathetic instability rather than indicative of a structural issue? 4. Have you encountered similar hyperadrenergic phases following viral infections that eventually eased over time? I know predicting exact timelines is challenging; I am primarily interested in whether the proposed neurological model and recovery projections appear physiologically sound. Thank you for your time — I genuinely appreciate any insights you can provide.

Thank you for sharing your detailed experience and concerns regarding post-viral dysautonomia after contracting Influenza B. Your symptoms reflect a complex interaction within the autonomic nervous system, and it’s understandable to seek clarity as you navigate recovery. Let’s address your concerns step by step.
Main Points
- Your described symptom trajectory aligns with concepts of post-viral autonomic dysregulation, particularly involving the brainstem.
- The transition from fully developed hyperadrenergic episodes to partial, aborted ones may suggest an improvement in autonomic control pathways.
- Symptoms like goosebumps, flushing, and eyelid twitching can be seen as signs of sympathetic instability rather than indicating a structural issue.
- There are documented cases of similar hyperadrenergic phases following viral infections that typically ease over time.
Explanation
Post-viral dysautonomia, particularly after Influenza B, can certainly lead to a range of autonomic symptoms similar to what you describe. The autonomic nervous system manages involuntary body functions, and disturbances can lead to symptoms like those you’re experiencing, including flushing, goosebumps, and emotional fluctuations. Your neurologist's insights about the brainstem's role in this dysregulation and the potential for neuroinflammatory factors affecting autonomic function provide a plausible framework for your current situation.
Improvements over your eight-month timeline are encouraging and suggest that your body is gradually recalibrating its autonomic response. The fact that some hyperadrenergic episodes have reduced in intensity and frequency is a positive sign of restoring balance.
Prioritized Next Steps
-
Focus on Nourishment: Since nausea and reduced appetite remain significant issues, consider small, frequent meals that are easy to digest. Clear broths, smoothies, or electrolyte drinks can help maintain hydration and nutrition.
-
Practice Relaxation Techniques: Incorporating stress-reduction techniques such as deep breathing, guided imagery, or mindfulness can support your autonomic transition to a more relaxed state. Regular practice may prove helpful, especially as you navigate episodes of heightened sympathetic activity.
-
Track Symptoms: Keep a detailed log of your symptoms, noting the frequency and severity of episodes. This may help you and your neurologist identify patterns and triggers, aiding further in your management plan.
-
Engage in Gentle Activities: If possible, gently flexible physical activities, such as yoga or tai chi, can improve autonomic function and may ease hyperadrenergic responses over time. Listen to your body and adapt your activity level as needed.
-
Stay in Touch With Your Neurologist: Regular follow-ups with your neurologist will be important for monitoring your progress. Any new or worsening symptoms should be reported promptly.
Your ongoing improvement and the proposed recovery timeline speak positively to the potential for your symptoms to stabilize further. Remember, recovery can be a gradual process, and you’re taking the right steps by being proactive in your health journey. If you need further discussion or specific resources, feel free to ask.

Inquiry Regarding MRI Results
A 22-year-old woman, measuring 5 feet 5 inches tall and weighing 125 pounds, recently underwent a pelvic MRI. The findings revealed a mild thickening in the peritoneum noted specifically within the cul-de-sac, characterized as T2 hypointense. This outcome is relatively common and may indicate superficial endometriosis or some degree of general scarring. Importantly, there were no indications of deep infiltrating endometriosis. While I understand that these results are not alarming, I struggle with health-related anxiety. Could someone please reassure me that this is nothing to worry about? Thank you!
Am I Left Without Alternatives?
Today, I visited a physician due to escalating discomfort in my right hip. I was diagnosed with Legg-Calve Perthes disease at the tender age of three, with the initial prognosis suggesting that I would need to rely on a wheelchair throughout my life. Fortunately, I defied that expectation and simply underwent regular monitoring by an orthopedic specialist who conducted annual X-rays. Having transitioned out of pediatric care, my hip is now presenting significant challenges. I find it difficult to rest on my right side, and have started limping intermittently while walking. Sleep evades me due to the pain, which seems to persist regardless of my position. At 19 years old, I received a rather disappointing response from the doctor. He indicated that my pain levels are not severe enough at this time and advised me to return for a follow-up once the discomfort intensifies. At that point, he would consider referring me to a specialist who could perform a hip replacement. Inquiring about interim pain relief strategies, I learned about a shoe lift that might help, given that my right leg is shorter than my left. Yet, the doctor characterized it as largely aesthetic, suggesting there are no meaningful solutions available right now. Can this be accurate? Am I truly out of options, or should I pursue a second opinion? I am a 19-year-old female residing in the United States, with primary diagnoses of Legg-Calve Perthes disease and Stickler Syndrome. Currently, I don’t take medications specifically for these conditions, apart from those prescribed for psychiatric issues and migraines.

Confusing Experience During Echo Examination: Is This Common?
Greetings. I'm a 21-year-old female, standing at 5'1" and weighing 240 pounds. My medical history, as noted in my patient portal, includes conditions such as Depression, Anxiety, ADHD, GERD, BRBPR, an elevated heart rate, DOE, Obesity, and Iron deficiency anemia caused by chronic blood loss. My current medications consist of Vyvanse, Pepcid, Iron supplements, Zoloft, and I've also been using NuvaRing. Recently, I underwent a Transthoracic Echocardiogram due to experiencing a rapid heartbeat and shortness of breath, particularly during activities like exercising or even playing with my nephew in a bounce house, which left me feeling faint and in need of a significant recovery period before my breathing and heart rate returned to normal. I have been under observation using a Zio Patch as well. Upon arriving for the echo, I was instructed to remove my shirt and lie on the examination table. The doctor proceeded with the procedure by applying gel to the transducer and beginning the scans on my chest, while also operating her computer. I was guided through a series of breathing techniques: short breaths followed by deep ones, ostensibly to help position my lungs for better imaging. This initial phase lasted around 15-20 minutes and was mostly quiet, aside from her reminders to hold my breath. She then indicated that the images weren't sufficient and that I would need to receive a medication to enhance the clarity of my heart images. A nurse came in to place an IV for administering this medication. Unfortunately, the experience was quite painful as he struggled to locate a suitable vein, resulting in discomfort with the needle moving around—which is something I usually find unpleasant, and this particular attempt left a strange bruise surrounding the entry point. After the IV was successfully placed, the doctor injected what I later learned was Difinity into the line. Communication about the procedure was lacking; she hadn’t provided much information as she resumed with the ultrasound. Almost immediately, I started to experience a tightening in my throat and chest, which made me visibly uneasy and caused me to lean back. When she asked about the tightness, I nodded, feeling too suffocated to respond verbally. Pain began to spread throughout my body, accompanied by dizziness and an intense heartbeat. I found myself twisting in discomfort and crying out, overwhelmed by the sensation, shouting "it hurts!" I genuinely felt like I was on the brink of collapse. She reassured me that what I was experiencing was typical and that I needed to remain calm, mentioning that it often feels worse before it gets better. Despite her reassurances, I couldn't help but feel frightened and exhausted as I laid there while she continued the exam by pushing more medication through the IV. This lasted for another ten minutes, during which my limbs felt strangely cold and I broke into a sweat. Eventually, she finished up and asked if I felt any relief before allowing me to dress. She offered no further explanation about my reaction or the procedure, stating that the doctor would reach out with the results. As we walked to the exit, she inquired again about my well-being, and I expressed that while I felt somewhat better, the ordeal was terrifying. She admitted that it was alarming and noted that the experience often feels worse than it actually is. I departed feeling both shocked and drained, recalling the experience as among the most distressing I’ve ever endured. I keep wondering why I wasn't forewarned about the potential side effects. Was her demeanor towards my discomfort too casual? Was my reaction typical? Am I right to be concerned? My feelings of frustration and confusion persist as I try to process everything that happened.
Adolescent Male Seeking Guidance on Neuromuscular Concerns
I’m an 18-year-old male, standing at 5'11" and weighing approximately 167 pounds, and I’m reaching out because I have escalating concerns regarding my neuromuscular health. My struggle with muscular weakness began roughly five years ago, and I’ve also been on medication for depression. This is my first post in years, and I’d like to share my experience. It all started in 2021 when I began to notice a peculiar sensation—an overwhelming feeling of persistent cold enveloping my entire body, accompanied by a slight pain that reminded me of a migraine. Unfortunately, these symptoms have progressed significantly over time. I now face challenges like loss of coordination, noticeable muscle weakness, joint discomfort, and a troubling feeling of trembling at times, making me feel as if my ligaments have endured a tough workout, despite my muscles still growing in size. I struggle to harness my full strength, often dropping things and stumbling into various objects like walls and furniture. Moreover, I have noticed a decline in my ability to communicate effectively and a general inability to focus, which manifests as brain fog. I frequently forget where I placed items, lose track of my tasks, and struggle to recall faces and names—even those I should know well. These issues seem to persist irrespective of my medication status. To clarify, I do have myopia and currently show no significant outward signs of my condition. While I experience stress like many others, I ensure that I get plenty of sleep and maintain a wholesome diet. Interestingly, it appears I am the only one among my siblings grappling with these difficulties. I would be deeply grateful if anyone could offer guidance on what steps I should take next. Despite visiting numerous doctors over the years, I have yet to receive a clear diagnosis, and living in a developing country has made seeking help even more daunting. Thank you for taking the time to read my concerns.
