Safety Considerations for Hiking with Possible Chiari Malformation
Hello, I’m a 25-year-old transgender woman residing in Colombia. Some years back, I was told I have Chiari malformation type II, though I now question whether it might actually be type I, as I don't exhibit symptoms like spina bifida or hydrocephalus. Unfortunately, I misplaced the documentation from that diagnosis. This was around the time I was managing gallbladder problems, culminating in its removal. Since losing my job, I’ve had no healthcare follow-up. Additionally, I have Gilbert Syndrome and do not consume alcohol. Recently, I have encountered several concerning symptoms: * Issues with coordination, which sometimes manifests as a delay between the command from my brain and the response from my muscles. Interestingly, I can still type at about 50 words per minute without difficulty. * A prevalent sense of "brain fog" that resembles what is often termed executive dysfunction; I suspect this might be exacerbated by anxiety. * My anxiety has increased, along with episodes of panic. I also have a confirmed diagnosis of autism and hyperthyroidism. Despite these challenges, I have enjoyed hiking Monserrate, a trail in Bogotá that ascends from approximately 2,500 meters to about 3,400 meters, gaining around 900 meters in altitude. I find this activity rejuvenating for my mental well-being; however, I am now anxious that it might be straining my spine or brainstem, potentially worsening my condition. Currently, I lack access to medical professionals but am actively seeking employment so that I can obtain insurance and pursue further evaluations. Hence, I would like to know: **Is it advisable for me to continue hiking at high elevations considering the possibility of having an undiagnosed Chiari malformation, or should I refrain from these activities until I can secure appropriate imaging?** I understand that no one here can provide a diagnosis, but I would greatly appreciate any insights regarding the risks associated with engaging in such physical activities while potentially dealing with Chiari malformation. Thank you for your assistance.

It’s great that you’re reaching out for information on managing your health while engaging in activities you enjoy. Given your history of Chiari malformation and current symptoms, including coordination issues and increased anxiety, it’s important to approach hiking with caution.
Main Points:
- You should be mindful of symptoms and the risks of high-altitude hiking with potential Chiari malformation.
- Prioritize monitoring your body’s responses and consider modifying your activities until you can seek further medical evaluation.
Explanation:
Chiari malformation, particularly types I and II, can impact neurological function and may cause symptoms such as headaches, coordination issues, or even brain fog due to pressure on the brain and spinal cord. Hiking at high altitudes can lead to changes in oxygen levels and increased physical strain, which could exacerbate symptoms. Although you find hiking beneficial for your mental well-being, it’s crucial to balance that with your physical health and symptoms.
Next Steps:
-
Monitor Symptoms: Pay close attention to how you feel during and after hiking. If you notice an increase in symptoms such as severe headaches, dizziness, or increased coordination issues, reconsider the intensity or frequency of your hikes.
-
Modify Activities: If you're experiencing increased anxiety and coordination problems, consider hiking shorter or less strenuous trails or choose lower elevations until you can get a clearer medical assessment.
-
Stay Active, But Safe: Continue physical activities like light walking or gentle exercises that do not strain your body while ensuring you relieve stress in other ways. Mindfulness or relaxation techniques could help manage anxiety and brain fog.
-
Prioritize Medical Evaluation: As soon as you have access to healthcare, seek imaging studies (like an MRI) to clarify the status of your Chiari malformation. Understanding your condition better will help guide you in making safe choices regarding physical activities.
-
Reach Out for Support: Consider connecting with local support groups or online communities for individuals with similar health concerns. Sharing experiences can provide insights and emotional support during this challenging time.
Taking these steps can help you enjoy hiking while being mindful of your health. If you have further questions or need additional information, don’t hesitate to ask. Stay safe and take care!

Ongoing Health Challenges Since January 2024: Experiencing Leg Pain and Weakness
Hello everyone. I’m reaching out in a state of urgency and uncertainty. I’m hoping that some of you might have insights or suggestions? (Just a note: I’m not a native English speaker, so I’ve tried my best with medical terminology, and I hope it’s clear enough.) My saga began in January 2024 when I started experiencing increasing discomfort in my back. By the middle of February, I endured intense pain in the mid-thoracic region. Upon visiting an orthopedist at the end of the month, I was dismissed as simply “overreacting.” Shortly thereafter, I noticed an unusual tingling and sensation of stinging in my legs, particularly around the thighs, accompanied by a persistent dull numbness. An MRI of my lumbar spine showed nothing unusual, but the thoracic MRI revealed two herniated discs at Th7/8 and Th9/10, which were compressing the spinal cord, although with no signs indicative of myelopathy. In April of 2024, a somatosensory evoked potential (SEP) test on my tibial nerve indicated that signals were not being transmitted to my brain. This finding was corroborated by doctors in the neurosurgery department, but they attributed the leg symptoms to other causes, leading me to a referral to neurology. By July 2024, after an admission to a neurology clinic and a lumbar puncture, the results were largely unremarkable apart from finding oligoclonal bands of type 4. The advice given was to seek outpatient treatment since no definitive cause could be identified. I began outpatient neurological therapy in August 2024, during which time I noticed a worsening of numbness in my hands, particularly affecting my thumbs, index, and middle fingers. Initially, I received minimal intervention until a nerve conduction study in December 2024 identified carpal tunnel syndrome, which has since deteriorated even while using a night splint, leading to a recommendation for surgery. Another nerve conduction study indicated issues with the peroneal nerve in my legs. In February 2025, I sought a second opinion from a different neurologist, coinciding with an orthopedic rehab program in January and February, unfortunately with no improvement. My symptoms intensified, along with troubling circulatory problems; my heart rate surged to 150–160 bpm upon standing or slight movement, only normalizing when I lay down. Currently, I am on beta-blockers to manage this. The new neurologist conducted an exhaustive re-evaluation, confirming carpal tunnel syndrome and tendinitis. Furthermore, along with the pre-existing disc herniations in my thoracic spine, a new herniation at C5/6 in my cervical spine was identified. A repeat SEP test reaffirmed that nerve signals to my brain were still lacking. Despite extensive examinations at a university hospital yielding normal results, I received a final diagnosis of functional disorder and chronic pain syndrome. My outpatient neurologist subsequently ceased my treatment. I find myself in a state of despair, battling daily pain. The discomfort in my thighs is pervasive, featuring a combination of dullness, sharp sensations akin to electric shocks, and immense weakness. My mobility has significantly decreased; previously, I could hike long distances, but now I struggle even on short walks. Additionally, the pain intensifies significantly right before my menstrual cycle, sometimes immobilizing me. I often feel dismissed by many medical professionals; I have to advocate fiercely for every test, desperate to reclaim my previous active lifestyle—filled with concert organizing, socializing, and dancing. Now, I mostly find myself isolated at home. Additional context about my health: - Female, 36 years old, normal weight, and historically active without engaging in specific sports. - Vitamin B12: 250 ng/L (slightly low but deemed acceptable by doctors; I'm managing this with supplements). - Abnormal 24-hour ECG showing ventricular events. - Creatine kinase: 360 U/L. - Chronic fatigue (I can only manage around three hours outside before needing a full day to recover). - Hand pain has improved slightly; however, my fingers still experience burning and numbness after use. - There’s some progress regarding pain in my forearms, yet I notice my right side is more adversely affected than the left. Is there anyone who can suggest further testing I may need? What additional steps can I take? It’s immensely challenging to accept that this might be my situation indefinitely. I would genuinely appreciate any insights or feedback. Thank you for taking the time to read my story!
Concerns About Leg Symptoms and Heart Rate
I am a 30-year-old woman, standing at 5'8" and weighing 160 pounds. My health issues began about two weeks ago, following a single injection of .50 ozempic I received 15 days prior. Besides this, I've been taking supplements including magnesium, fiber, and antacids, but no other medications. Approximately six days after administering the ozempic injection, I went to the emergency room due to a worryingly high resting heart rate, which reached 157 while standing and averaged between 100-130 when seated. This abnormal heart rhythm persisted intermittently for five days before I decided to seek medical help. During my ER visit, my blood pressure was recorded at 135/92, and various tests including blood work, an electrocardiogram (ECG), and an X-ray all returned normal results. Last night, I found myself back in the ER experiencing similar symptoms: my heart rate spiked to 130 while I was sitting, accompanied by chest discomfort and difficulties in breathing after light activity. This time, my blood pressure was higher at 152/93. We conducted blood tests, an ECG, and a heart scan to investigate the presence of blood clots in my lungs, yet all results were still within normal ranges. I noticed some swelling in my feet during this visit, and the physician advised me to elevate them. Since being home, I've been struggling with circulation in my legs and feet. My thigh muscles are extremely painful, and I observe pronounced blue veins resembling spider veins bulging in my feet. While I did experience some swelling initially, elevating my feet helped alleviate it. I’m contemplating whether these ongoing issues necessitate another ER visit or if they may simply stem from reduced physical activity over the past couple of weeks. Although the ER referred me to see a cardiologist, I’m informed that obtaining an appointment could take weeks. Additionally, it’s worth noting that I have no previous history of heart palpitations or circulatory problems. This situation is quite perplexing for me, leaving me eager for clarity and solutions regarding my symptoms.
Concerns About HIV Exposure in the Operating Room
I hope this doesn't come off as a silly inquiry, but I need some reassurance. I am employed in the operating room and recently entered a procedure to assist a colleague. Upon my arrival, the scrub tech requested that I connect a suction irrigator. Unfortunately, I did this without wearing gloves (I understand this was unwise and I’m aware of the risks; it had been a rather exhausting day). Shortly after, the nurse informed me that the patient was HIV positive. Additionally, I noticed that the scrub tech's gloves were stained with blood. On the same hand I used to handle the irrigator, I have a small cut on my palm from a cat scratch that occurred two days earlier, which had bled. There were no visible signs of blood on the irrigator itself. Am I overreacting to this situation?
Understanding Arachnoid Cysts: Symptoms and Concerns
Hello, As a 30-year-old woman, I recently underwent an MRI scan in the context of being evaluated for cochlear implants. For some time, I have been struggling with my hearing; it has steadily declined, making conversations challenging, even while using my hearing aids, which I've had for five years. Following a CT scan, my physician recommended an MRI, which ultimately revealed an arachnoid cyst in the anterior temporal lobe on the left side. Growing up without health insurance meant that my medical concerns went uninvestigated until my mid-twenties. I experience a range of troubling symptoms that are managed by various healthcare professionals, including disabling migraines that can leave me incapacitated for hours, nausea, dizziness, tinnitus, balance issues, fatigue, and most notably, significant hearing impairment. Recently, I have become increasingly worried as my vision is deteriorating—it's becoming difficult to focus on objects even when they are just a few feet away. I can't tell if this is simply due to aging or if it could possibly be connected to the cyst. At my neuro clinic, the physician's assistant indicated that my symptoms are unrelated to the cyst and suggested its discovery was coincidental. However, I can't help but wonder if all these symptoms could be interlinked rather than viewed as isolated issues. I would greatly appreciate any insights or perspectives on this matter. Below, I have included key findings from my MRI that detail the cyst. **MRI FINDINGS**: - **Internal Auditory Canals and Cerebellopontine Angles**: Right IAC shows exostosis at the porus acousticus, anterior-superior margin, which is in contact with, yet does not displace, the right 7th cranial nerve. - **Cochlea, Vestibule, Semicircular Canals**: Appear normal in signal and structure. - **Brainstem and Cerebellum**: Normal appearance. - **Remaining Brain Parenchyma**: No indications of acute infarct or hemorrhage, no mass effect or herniation. The white matter signal appears normal. Notably, a 3.1 x 1.2 cm cyst was identified in the left anterior temporal region.
Concerns Over Low Blood Count and Ongoing Symptoms at the ER
A 38-year-old female weighing 148 pounds and standing at 5 feet tall has been facing a variety of health challenges including fibromyalgia, chronic fatigue syndrome, migraines, thyroid problems potentially linked to Hashimoto's disease—which is still under investigation—alongside depression, anxiety, gastroesophageal reflux disease (GERD), a hiatal hernia, and fatty liver issues. Recently, she sought treatment in the emergency room after experiencing two weeks of persistent chest pain, fatigue, shortness of breath, and abdominal discomfort. She decided to visit the ER when her blood pressure elevated. Upon examination, her blood work indicated a low red blood cell count of 3.67, a hemoglobin level of 10.9, and a hematocrit of 32.3. Given these findings, she is concerned that these results reflect anemia. While she acknowledges that these values may not be critically low, she recalls a past instance where she required an infusion due to similar counts. At the time of her emergency visit, her blood pressure remained high, but surprisingly, the medical team did not conduct a follow-up on her vital signs before discharge. Tests for troponin levels and an EKG returned normal results. However, she still feels unwell and has an appointment scheduled with her primary healthcare provider this Monday. Despite the ER doctor's reassurance that her condition was "normal," she is left questioning whether this assessment is accurate, especially since no further tests for iron or other relevant factors were completed after the initial blood results. Any feedback or insights on her situation would be greatly valued!
