Concerns About Brain-Eating Amoeba After Swimming
At the age of 21, I am assigned male at birth, living in Minnesota, and I have a diagnosis of autism along with anxiety and depression. Currently, I’m undergoing treatment with bupropion XL at a dosage of 150. I feel a bit silly for asking this, but I’m in need of some reassurance. Three days ago, while at my family cabin in northern Minnesota—far from the boundary waters and the Great Lakes—we took a boating trip. We eventually anchored at a lake along the chain we were exploring, where we decided to take a swim. Unfortunately, I inadvertently inhaled some water through my nose as I jumped in, which immediately triggered a wave of anxiety about possibly contracting a brain-eating amoeba. Since that moment, I’ve been consumed by worry. I understand that reassurance might not effectively address my health anxiety, but I am seeking assistance. From what I’ve learned, there have only been a couple of reported cases in my state, both of which occurred in lakes distant from where I was swimming. However, that doesn’t guarantee that the amoeba was absent from my lake, does it? The weather was quite warm, reaching the 80s and 90s, and we had some sunny days, although it rained a few days prior. While I realize that temperatures are typically warmer in southern regions, I’m still anxious. The lake where we swam was part of a chain with a lot of boating activity, including a restaurant where visitors could dock their boats, so it didn’t seem like stagnant water. Since that swimming incident, I have experienced minor neck stiffness, occasional headaches, and some nausea. I am aware that these symptoms can often be manifestations of anxiety, especially considering my health anxiety, yet I remain uncertain. If anyone could help ease my fears, I would be incredibly grateful.

It's completely understandable to feel anxious after an experience like swimming in a lake, especially in relation to serious concerns like a brain-eating amoeba. While your worries are valid, let’s break this down calmly and provide some reassurance.
Main Points
- Risk Assessment: The risk of contracting a brain-eating amoeba (Naegleria fowleri) from swimming in lakes is very low, especially in Minnesota.
- Symptoms & Anxiety: The symptoms you're experiencing—neck stiffness, headaches, and nausea—are commonly associated with anxiety rather than an infection.
Explanation
Brain-eating amoeba infections are extremely rare. They typically occur in warm freshwater environments, often in southern states, and require specific conditions to thrive. While the water temperature and conditions can influence the amoeba's presence, the lake you swam in, being a recreational area with regular activity, likely posed minimal risk.
The symptoms of a Naegleria fowleri infection usually manifest rapidly and severely, with characteristic signs such as fever, headache, nausea, and confusion. Given that you've only experienced mild symptoms and they've developed days later, this aligns more closely with anxiety rather than an infection.
Next Steps
-
Mindfulness and Anxiety Management: Consider engaging in calming techniques such as deep breathing exercises or mindfulness meditation. This can help soothe your anxious thoughts.
-
Monitor Symptoms: Keep a close eye on your symptoms for the next few days. If they worsen significantly (e.g., intense headaches, high fever, confusion, or severe neck stiffness), it's advisable to seek medical evaluation.
-
Stay Hydrated and Restful: Ensure you are drinking enough water and getting sufficient rest. This can help alleviate general feelings of discomfort.
-
Limit Exposure to Triggers: Since you’re aware of your health anxiety, restrict your exposure to information about Naegleria fowleri and related topics for a while to prevent information overload.
-
Reach Out for Support: Consider discussing your concerns with a trusted family member or friend who can provide support, or even consider additional therapeutic support if you feel overwhelmed.
Remember, you are not alone in feeling anxious, especially about your health. It's entirely okay to ask for reassurance and seek support when you need it. You’re taking proactive steps by seeking this information, which is commendable. Let me know if you need further reassurance or help with specific strategies to manage your anxiety!

Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight
As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
Seeking Insights: My Journey with Undiagnosed Neurological Symptoms
Hello everyone, I'm a 34-year-old female grappling with neurological symptoms that first appeared in October, and I’m eager to hear from anyone who might have faced similar challenges. My journey began with unexpected migraines, blurred vision, and an ongoing sensation of being off-balance or intoxicated. Gradually, I began experiencing mainly sensory-related symptoms, such as tingling and burning sensations, feelings of extreme heat and cold, sharp pains radiating in my arms and back, as well as discomfort in my hands and toes, alongside intermittent numbness. I also endure varying degrees of weakness and heaviness in my right side, specifically my arm and leg, although I haven’t suffered complete functional loss. The nature of my symptoms is erratic; they fluctuate rather than consistently deteriorate. An MRI revealed mild, scattered lesions in the white matter, which were deemed nonspecific. Further tests from a lumbar puncture returned normal results, showing no markers of inflammation, and the oligoclonal bands were not present. A thorough range of lab tests yielded no significant findings. After evaluating my case, the neurology team suggested a possible diagnosis of MS and administered a three-day course of intravenous steroids. While I noticed a slight improvement in some sensory pain, my symptoms persist and continue to vary day by day. I still experience headaches and pressure in my head along with episodes of blurred vision, but there have been no new deficits since treatment. I am reaching out to connect with others who have had similar experiences. I would like to learn about the insights or diagnoses you encountered and what treatments proved beneficial (such as those related to migraine disorders, dysautonomia, or sensory neuropathy, for example). If you have navigated a similar path, I would greatly appreciate your sharing your story. Thank you!
Should I Seek Medical Attention for Left Ear Pulsatile Tinnitus?
A 31-year-old woman reports an ongoing issue with pulsatile tinnitus, which she is currently experiencing solely in her left ear. Although she's noticed this condition intermittently before, she hadn’t paid it much mind due to the absence of pain. Recently, however, her curiosity piqued her interest in researching the condition, where she stumbled upon information suggesting it could be serious. Usually, she avoids searching online for health worries, but now she is contemplating whether a visit to the doctor might be warranted. Can anyone advise on the need for a medical evaluation in this case?
Concerns About Angular Cheilitis
I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.
Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.
