Assessing My Risk of Naegleria fowleri Infection

6/21/2025, 4:40:25 AMMale25-34

I am a 13-year-old male and recently enjoyed some swimming at Gold Mine Lake in Michigan, close to Ishpeming. During my time in the water, I accidentally inhaled some through my nose. The temperature of the water was chilly, though it’s possible that it was somewhat warmer. Since that incident, I have been overwhelmed with anxiety about the possibility of contracting a fatal infection, particularly Naegleria fowleri, especially since I neglected to use a nose clip while swimming.

It's understandable to feel anxious after such an experience, but let's calmly assess the situation regarding Naegleria fowleri infection. While inhaling water can be concerning, the risk of contracting this rare but serious infection is very low, particularly from swimming activities in most lakes.

Key Points:

  1. Naegleria fowleri is most commonly found in warm freshwater environments, like hot springs or poorly maintained swimming pools, rather than in cold water.
  2. The majority of infections occur when water containing the amoeba is forcefully introduced into the nose, often during activities like diving into warm freshwater.
  3. The chances of getting infected are extremely rare, with only a handful of cases reported annually in the U.S.

Understanding Naegleria fowleri:

  • This amoeba can cause a severe brain infection called primary amoebic meningoencephalitis (PAM), but it is essential to note that it occurs only under specific conditions.
  • Symptoms often appear within 1-9 days after exposure and can include headache, fever, nausea, vomiting, and a stiff neck.

Next Steps:

  1. Monitor Symptoms: Keep a close watch for any unusual symptoms in the following days or weeks, such as severe headache, fever, or changed mental status.
  2. Hydration and Rest: Ensure you are staying hydrated and getting plenty of rest, as this helps overall health.
  3. Limit Anxiety: Consider relaxation techniques such as deep breathing or talking about your concerns with someone who can provide support. Anxiety about health can be common, but addressing it can relieve stress.
  4. Educate Yourself: Knowing more about Naegleria fowleri and its transmission can help ease your worries. Trusted resources like the CDC offer detailed information about the risk factors and prevention strategies.
  5. Consult if Necessary: If you start experiencing symptoms or continue feeling anxious, it may be helpful to discuss your concerns with a trusted adult or healthcare provider who can provide reassurance.

Stay calm and take proactive steps to care for your mental and physical health. If you have further questions or need support, feel free to ask.

Inability to Sneeze: Potential Neural Communication Issues

Hello. I’m seeking assistance to comprehend my situation and explore possible remedies. I’m a 25-year-old male working as a software engineer and currently not taking any medications. For the last two years, I have experienced an inability to sneeze. This issue first arose following two significant incidents involving exposure to neurotoxic substances, which led to a variety of neurological symptoms. 1) **Vitamin B6 Toxicity**: Over a span of 4-6 weeks, I received seven intramuscular injections of a B-complex vitamin, each containing 100mg of Vitamin B6 in the pyridoxine form. Shortly after beginning these injections, my health rapidly declined, and numerous symptoms emerged. Research has identified pyridoxine as potentially neurotoxic, with recent documentaries and studies — particularly from the Australian community — raising awareness about this condition. In response, Australia’s Therapeutic Goods Administration (TGA) has taken steps to restrict the sale of B6 supplements and to lower their permissible amounts. For more insight into the seriousness of this issue, you can find several informative short documentaries on the ABC News YouTube channel. 2) **Insecticide Exposure**: While undergoing the B6 treatment, I also encountered a concerning situation where I inhaled toxic insecticide fumes. Not realizing the danger due to nasal congestion from a minor illness, I sprayed a considerable amount of insecticide in my room. It was only after I started coughing that I realized I had been breathing in these harmful fumes. It occurred late at night when I was already feeling unwell, and I opted to go to sleep shortly afterward. Both incidents occurred in September to October of 2021, after which I began to experience an alarming array of around twenty symptoms affecting my sensory, motor, and autonomic nervous systems. I developed severe numbness and tingling in various parts of my body, involuntary muscle movements, ataxia, facial numbness accompanied by a loss of muscle volume in my face due to nerve damage, and symptoms that resembled diabetes such as excessive thirst and fatigue post-meals. Other issues included rapid heart rate, skin lesions, an inability to sweat, extreme muscle weakness, and significant psychological symptoms, including emotional numbness and anhedonia. Virtually every area involving nerves seemed to be impacted. Now, 18 months later, I’ve made considerable progress, with most of the symptoms easing, but I still struggle with the inability to sneeze. Recently, after experiencing a flu, I noticed that my body failed to sneeze about 90% of the time. I feel the urge to sneeze starting deep in my lungs, traveling to the tip of my nose, yet it rarely culminates in an actual sneeze. Instead, I feel pressure released in alternative ways, sometimes sensed as pressure in my head, and occasionally, I experience tears running from my eyes and nose when the sneezing sensation arises, yet no sneeze follows. Despite waiting a year and a half for recovery and seeing improvements in my larger nerves, these specific bodily functions remain unresolved. A recent electromyography (EMG) and nerve conduction study (NCS) conducted two weeks ago returned normal results, which aligned with my awareness of the recovery in my larger nerves and muscles during this period. Through my research, I’ve discovered that the trigeminal and cranial nerves play a crucial role in initiating a sneeze, suggesting the presence of a signaling issue. I would greatly appreciate guidance on this matter.

Lower Lip Abscess in a Young Child

My four-year-old is dealing with a lower lip abscess. What began as a small crater on his lip last Sunday rapidly progressed to a pus-filled lesion by Monday night. By Wednesday evening, we managed to see a pediatrician who admitted him for intravenous antibiotic therapy. Since being hospitalized on Wednesday night, he has been receiving Sulvacil through an IV. A general surgeon evaluated him yesterday but chose not to perform an incision for drainage, stating that managing a lip wound would be quite challenging at his age. Currently, I'm feeling uncertain about the progress of his condition, as the abscess appears to still contain pus. It seems to swell and then reduce in size only to fill up again. Despite this, my child remains lively and has a good appetite, though he does experience discomfort when trying to chew. I’m left wondering if we are observing any tangible improvement, or if it might still be too soon to judge the situation?

Understanding a Nodular Finding on My Appendix: Seeking Clarity

I'm a 22-year-old female, standing 4'9", with a background of EDS and anxiety. Recently, on January 30, 2026, I visited the emergency department due to kidney discomfort, which turned out to be a kidney stone. While reviewing my CT scan report to recall the size and location of the stone—still lodged and proving quite troublesome—I stumbled upon a mention of a nodular area on my appendix. This detail was not brought up by my doctor during my visit. Although I suspect it may not signal a serious issue, I'm curious if this is something I should discuss further with my primary care physician. Can anyone clarify what a nodular finding on the appendix means? I came across some information suggesting it could indicate a tumor, but I’m aware that online medical searches can often lead to misunderstandings. Any insights would be appreciated!

Dealing with Esophageal Cramping and Heartburn while on Oral Minoxidil

Hello everyone. I’m a 37-year-old male who frequently experiences alopecia areata, particularly during stressful periods at work. Recently, my dermatologist recommended oral minoxidil in 2.5mg capsules to speed up my hair restoration process. Since I began this treatment, I’ve encountered several side effects, including elevated heart rate, dizziness, shortness of breath, heartburn, and esophageal cramps, albeit not all at once. Most of these issues have subsided, but the cramps and intermittent heartburn persist. I find the cramps tend to occur after meals, accompanied by a sensation as if I can feel the food moving through my esophagus; this uncomfortable feeling can linger for hours before fading, only to return with my next meal. The discomfort isn’t severe enough to incapacitate me, but it can be quite bothersome, with some days being better than others. Should I consider halting the medication, or should I wait until my next scheduled appointment to discuss this? I live in a rural area, making it difficult to find sooner availability, as the next appointment isn’t for another month. I appreciate any advice you might have!

Ongoing Symptoms Post-Concussion: Seeking Insights

Hello everyone, I’m a 25-year-old male and experienced a significant car accident about two and a half years ago. Although I didn't black out during the incident, I felt disoriented and unsettled immediately afterward. Since that day, my health has noticeably deteriorated, and I'm attempting to discern whether my current struggles are commonplace or if something more serious might be overlooked. Here’s what I've been grappling with: I endure daily headaches that typically originate in the back of my head or neck, gradually migrating towards my temples or eyes. Conditions that intensify these headaches include bright screens, excessive light, noise, and bustling surroundings. When I attempt to power through the discomfort, I sometimes see halos around lights or experience visual static. Mentally, I find myself exhausted very quickly. Concentrating becomes a challenge, and I frequently lose track of my thoughts or encounter difficulty finding the right words. Engaging in conversations or attending meetings can drain me significantly. Additionally, I become easily overwhelmed, especially in loud or crowded situations. Tinnitus is another issue I face, as the ringing in my ears is a constant presence. Since the incident, I’ve noticed weakness in my left hand; my ring and pinky fingers often curl up like claws. An electromyography (EMG) test revealed damage to the ulnar nerve, which accounts for some of this phenomenon. Unfortunately, it hasn't improved, impacting my ability to type, grip objects, and carry out everyday tasks. I also experience occasional facial twitching, jaw tightness, and short bouts where different parts of my body feel weak or tremble, but these symptoms are temporary. Fatigue is a significant battle for me. I struggle with poor sleep quality, waking up feeling unrested, and sometimes experiencing anxiety first thing in the morning. Even on days when the pain level is tolerable, my energy depletion restricts my activities. Here’s a summary of what medical evaluations have revealed: • My brain scans returned normal results, revealing only minor, nonspecific findings like white matter changes in certain regions. • The blood vessels in my brain appeared healthy. • EEG results indicated some slowing but no evidence of seizures. • More invasive tests ruled out any major health concerns. • Mild sleep apnea was detected. • Cognitive assessments showed deficits in attention, processing speed, and memory. • Eye examinations indicated challenges with tracking and focusing post-injury. What has proven somewhat beneficial includes: • Migraine medication has helped lessen the severity of my headaches. • Telecommuting allows me to take frequent breaks. • Engaging in occupational, speech, and vision therapy whenever possible has been somewhat advantageous. I maintain a full-time job, but managing it drains a considerable amount of my energy, leaving little for family interactions, social engagements, or time for recovery. I’m at a stage where I’m seeking clarification on several points: 1. Is it common for post-concussion symptoms to persist for such an extended period despite normal scan results? 2. When is it appropriate to seek an alternative explanation rather than accepting a diagnosis of merely post-concussion syndrome, stress, or anxiety? 3. Is it typical for fatigue to be the most pronounced and debilitating symptom? 4. Are there often overlooked aspects, such as sleep quality, visual processing, nerve health, or nervous system function, that should be reevaluated? I’m not seeking a diagnosis—just some insight. I want to determine whether I’m on a reasonable track or if I should be considering different inquiries. Thank you to all who have taken the time to read my message.
