Distinguishing Between FND Shutdowns, NES, and Autonomic Mini Storms
The title sums it up well, but I’d like to delve deeper into the topic. I’m seeking clarification on how to differentiate among functional neurological disorder (FND) shutdowns, non-epileptic seizures (NES), and autonomic mini storms. Additionally, I am curious about the methods my neurologist might use to assess my condition. I am a 28-year-old woman, standing at 5 feet 3 inches tall and weighing between 100 and 105 pounds, with slight fluctuations in weight that matter to me. I am a smoker and formerly consumed alcohol, although I no longer do so. I have children and battle multiple health issues, including dysautonomia, fibromyalgia, psoriasis, and severe endometriosis. On the mental health front, I have been diagnosed with ADHD, complex PTSD, and potentially bipolar disorder, though I personally believe that my struggles with brain fog and ADHD significantly impede my mood and daily life. Currently, I am on the lowest possible doses of fludrocortisone and propranolol. Approximately two and a half weeks ago, I began experiencing recurring "episodes," and they have been incredibly distressing. During these times, I tremble, sweat excessively, and my heart rate and blood pressure deviate from what is normal for me. I often find myself unable to move or speak. While I usually retain consciousness, I unfortunately lost it during a particularly severe episode the other day. I have an upcoming appointment with my neurologist in a few days, but my anxiety is pushing me to want to understand what I might expect and how to communicate my experiences effectively. I managed to record a milder episode, but I haven’t been able to capture the more intense ones yet; I consider myself fortunate to have documented that one. Given my dysautonomia, I can’t help but wonder if it plays a role in my episodes or exacerbates them. For further insight, I’ll share that during a significant episode, my mother had to call emergency services. When they arrived, they conducted an EKG, which indicated I might have had an anterior heart attack. Immediately following the episode, my heart rate soared above 160 beats per minute, but by the time I reached the hospital, I was back to what is normal for me (albeit I have ongoing irregularities, including some tachycardia and occasionally bradycardia). I haven’t pinpointed specific triggers for these episodes, although heat seems to be a factor among others. During an episode, I often shake intensely, feeling cold despite profuse sweating. My eyes may oscillate between being open and closed, and I frequently experience sensations akin to choking. Despite being able to see and hear when my eyes are open, my perception feels distorted, as if I were submerged in water. My mouth dries out, and I struggle to articulate words. Just before the onset, a wave-like sensation washes over me, accompanied by nausea. I typically rest with my legs elevated, but this rarely alleviates my symptoms. The experience is draining and painful, causing me to unwittingly curl into a fetal position or kick out in distress, with emotional aftermaths often leaving me in tears. Based on all this, do my symptoms align with any of the conditions mentioned? What are the probable steps my neurologist will take during my upcoming visit? I’m feeling apprehensive and apologize for the somewhat scattered nature of my narrative; my brain fog has been quite pronounced lately. Thank you so much in advance for your help! Extra appreciation to those who made it through my lengthy description! P.S. I have some additional diagnoses that I need to discuss as well.

Thank you for sharing your experiences so clearly, and I appreciate how challenging this has been for you. Let's break down your concerns regarding the potential distinctions between functional neurological disorder (FND) shutdowns, non-epileptic seizures (NES), and autonomic mini-storms, as well as what to expect from your upcoming appointment with your neurologist.
Key Points:
- Distinguishing Symptoms:
- FND Shutdowns: Often characterized by neurological symptoms (like movement disorders or speech difficulties) that don’t have a clear medical explanation. These can be triggered by stress or psychological factors.
- Non-Epileptic Seizures (NES): Similar to seizures but are not caused by abnormal electrical activity in the brain. NES may involve shaking, loss of awareness, and can be associated with extreme emotional distress.
- Autonomic Mini Storms: These likely relate to dysautonomia, where your autonomic nervous system experiences a dysregulated response, leading to symptoms like profound sweating, heart rate changes, and altered blood pressure.
Understanding Your Symptoms:
From your description, it seems like your symptoms could overlap with these conditions, particularly given your history of dysautonomia and the distressing nature of the episodes. The trembling, dysregulation of heart rate and blood pressure, sweating, and feelings of choking could suggest either NES or autonomic dysregulation, possibly exacerbated by FND.
Next Steps for Your Neurologist Appointment:
-
Symptom Documentation: Since you recorded a milder episode, try to provide this to your neurologist. If possible, prepare a summary of your episodes, noting their duration, triggers, and any accompanying symptoms.
-
Medical History Review: Your neurologist will likely take a comprehensive look at your medical history, including your previous diagnoses and current medications (like fludrocortisone and propranolol).
-
Neurological Exam: Expect a thorough neurological exam to assess your reflexes, coordination, and sensory responses.
-
Diagnostic Tests: Your neurologist may recommend tests to rule out seizure disorders (like EEGs) or other investigations to evaluate your autonomic function.
-
Discussion on Triggers: Be ready to talk about observed triggers, like heat, and how they seem to relate to your episodes, as this will help in formulating a management plan.
Actionable Guidance:
- Maintain a Symptom Diary: Note when episodes occur, potential triggers, and their duration. This information will aid your neurologist.
- Stress Management Techniques: Given your anxiety and the nature of your episodes, practices like deep breathing, mindfulness, or gentle yoga may help.
- Lifestyle Adjustments: Stay hydrated and regulate your body temperature (avoid overheating) to help manage dysautonomia symptoms.
Your feelings of anxiety are completely understandable, especially with the complexity of your symptoms. Remember that seeking help and clarification is a strong step toward understanding and managing your health better. You're not alone in this, and your neurologist is there to support you. Please feel free to reach out for more specific concerns or if you have questions about particular aspects of your health management.

Navigating Ear Infections While Traveling in Thailand
**Age:** 23 **Height:** 6'3" **Weight:** 88 kg **Medication Taken:** 1000mg Bactoclav - Amoxicillin with Potassium Clavulanate, along with pain relief and antihistamines. **Summary:** I’m hesitant to consult a doctor overseas only to receive a prescription for the same antibiotics available at a local pharmacy for a fraction of the price. What strategies can I employ to effectively manage this persistent ear infection? Am I being too hasty in my expectations? I have a long history of ear infections, often triggered by exposure to water or any activity impacting my ears. I regularly use a specialized oil before showering to prevent water from entering my ears. While backpacking in Thailand, I've developed a particularly severe ear infection over the last several days. Initially, a course of 500mg amoxicillin seemed effective, but significantly, just yesterday my condition took a downturn, shifting from nearly healed to painfully inflamed. Now, my ear is not only swollen but also incredibly sore. In an attempt to combat this, I’ve been taking 1000mg Bactoclav - Amoxicillin and Potassium Clavulanate, having consumed seven tablets in the last two days; unfortunately, there's been no noticeable improvement. I’m reluctant to seek medical attention, fearing I would be prescribed the same medication I could acquire from a pharmacy, albeit at a much higher cost. Yet, I’m also starting to question the efficacy of the pharmacy’s medication. I’ve only recently begun the stronger treatment since my symptoms returned. Any advice would be greatly valued! In addition, I’d like to share that just a week into my four-month journey, I feel as though my ongoing ear issues are gradually dominating my life. I am incredibly grateful for this travel opportunity, and while my health isn’t at risk in a serious way, these ear complications are becoming quite overwhelming. Could there be surgical options available? Might there be an underlying health concern that I’m unaware of? It doesn’t seem normal to be plagued by constant ringing, popping sounds, and wax buildup in my ears. Moreover, it feels excessive to have to apply products in my ears every time I shower.
Navigating Health Concerns: A Young Woman's Plight with Chronic Migraines and Stress
To summarize a very complex situation, last spring in 2025 was exceptionally challenging for me. I faced overwhelming stressors, including family deaths, eviction, and my parents splitting up. This turmoil led to chest pains so severe that I had to visit the emergency room because I couldn’t breathe deeply without experiencing intense pain. The doctors attributed the issue to psychological causes, but I continued to suffer from pain and instances of fainting due to the stress, which worsened as yet another family member was diagnosed with cancer. My psychiatrist suggested medication, and I started on Lexapro and Concerta, which improved my condition somewhat, even though I remained fatigued and felt like I was merely surviving. By the end of August, I contracted a severe case of bronchitis that caused me to experience fevers even while doing laundry. It seemed I was verging on pneumonia, prompting the prescription of prednisone and other steroid medications. Thankfully, I began to recover quickly, but soon after, I was plagued by persistent headaches and an overwhelming sense of paranoia that someone was out to get me. After another emergency room visit, the physicians informed me that, although my symptoms—such as fever, intense pain, night sweats, sensitivity to light, ear pressure, and a stiff neck—were alarming, they were likely just severe migraines that should eventually fade. Unfortunately, they didn’t. I returned to urgent care for further treatment, received antibiotics, and was advised to consult a neurologist. While the antibiotics provided some relief, my symptoms intensified. My primary care physician eventually prescribed sumatriptan, a medication intended to alleviate migraine pain, but instead, it exacerbated the headache. For the next two to four weeks, I endured an exceptionally difficult time, facing numerous strange symptoms that felt worthy of immediate attention, yet each visit concluded with a migraine diagnosis and a waiting period for my neurology appointment. My frustrations pushed me to contemplate risky alternatives for relief, but I resisted, feeling utterly hopeless and unable to cope. I sought an ear, nose, and throat specialist to rule out sinus issues, which turned out to be fine. A painful spot under my jaw led me to suspect nerve involvement, and I visited the emergency room again due to experiencing stroke-like symptoms (including mild left arm weakness, extreme headache, and minor speech issues). Sadly, I was again told it was merely a headache, and the IV medications were ineffective. During my annual check-up, my primary care provider was unfamiliar with my ongoing issues but discovered an enlarged lymph node in the lower left side of my neck and a cyst on my thymus after conducting a soft tissue scan. She reassured me that there was no need for concern and suggested waiting for my neurology visit or getting my eyesight checked. Despite my yellower complexion, increasing stiffness, and joint pain, I accepted her recommendation. While I mentally adapted to the chronic pain, which was always present, it affected my ability to concentrate and engage in daily life. I tried consuming plenty of lemon juice and engaging in lymphatic drainage massages, which provided transient relief and halted my yellowing skin. Now, in the present, I've noticed a peculiar, raised red bump on the side of my foot. It’s hard, tender, and smaller than a dime, without any accompanying rash. It has persisted for a couple of weeks without causing pain while walking. Additionally, more lymph nodes in my neck have become swollen, I have experienced difficulty swallowing, and I occasionally choke on air. My lungs feel heavier with a diminished sense of smell, though I don't have the thick mucus typical of a cold. The headaches, however, are reemerging, sharper than before, which is a concerning development. Throughout all of this, my blood pressure has remained within a low yet stable range, and my blood tests and CT scans have shown no significant issues. I haven’t consumed anything excessively that might raise concern, including food or drugs. Am I truly facing a serious health crisis? Should I prioritize getting another appointment, or do I need to rush to urgent care? I'm scheduled to see the neurologist in about a month, and I'm wondering if I should ask my primary care provider for some preliminary tests like blood work or an MRI beforehand. If so, what specific questions should I prepare for my neurology visit? I believe the pain has a genuine physical basis, although my anxiety definitely amplifies the experience.
Injury to the Sciatic Nerve
At 25 years old and weighing 135 pounds, I am currently taking naproxen and Lyrica to manage my sciatic nerve injury. The pain in my right leg has made it incredibly difficult for me to remain upright. It’s been two weeks since I first sought treatment; I consulted a physician who advised medication and attended a physiotherapy session. Initially, I experienced some relief after the appointment, but unfortunately, the pain returned the following day—even the prescribed home exercises exacerbated my discomfort. Just yesterday, I attempted the cobra pose, along with the flossing technique, which only heightened my pain. I find it nearly impossible to stand for more than a few seconds before the discomfort becomes intolerable. Additionally, I have an appointment with an osteopath on Tuesday, but I can't shake off my worries— is it normal to still struggle with walking after two weeks? Although I am experiencing some numbness in my toes, I haven’t encountered any loss of bladder or bowel control, worsening numbness, or weakness in my legs, so I feel stable in that regard. Nonetheless, I fear the possibility of never fully recovering and being left with a lasting disability. The pain is overwhelming, adding to my anxiety about the future.
