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!

Concerns About Oral Lesions in My Brother
I am deeply worried about my younger brother, M, who is 19 years old. For the last few years, he has been dealing with white, lesion-like formations emerging in the corners of his mouth. These white patches become itchy and inflamed particularly after he consumes red meat, like pork. As a result, he has shifted his diet to primarily include fish and chicken. Initially, we suspected that he might be suffering from allergies, yet the physicians we have consulted have struggled to provide a definitive diagnosis regarding these white lesions and their connection to the consumption of red meat. Additionally, medical evaluations revealed that his uric acid levels are elevated, which is concerning especially for someone his age—this was noted last year when he was 18. My mother and the rest of our family are increasingly anxious about his situation. We're seeking advice on what steps to take next. Is there anyone who has experienced something similar? We would appreciate any insights into what this condition might be, as we aim to understand the underlying issue more clearly.
Persistent Chest Lump: Possible Cyst?
Hello! I’m a 22-year-old woman and for the past couple of months, I’ve noticed a lump on my chest. It resembles a cyst or a deep acne lesion in both appearance and texture. When I apply pressure, it releases pus, which can vary in color from white to brown or even black. The surrounding area appears red and is tender to touch. At times, it feels sore even without any contact. Furthermore, I’ve observed a tiny black dot at its center from time to time. I’m reaching out for some insights on what this could potentially be. Thank you for your help!
Understanding Sjögren's Syndrome
My 63-year-old aunt is grappling with Sjögren's syndrome and is earnestly looking for ways to alleviate her discomfort.

Ortho/Neuro Concerns: A Case Study
A 28-year-old female patient encountered a stress injury affecting her lower extremities about a year ago, which necessitated a six-week period of immobilization using crutches. Shortly after being cleared to resume weight-bearing activities, she began to experience debilitating muscle soreness and stiffness in her upper body without any identifiable trigger. This was accompanied by episodes of involuntarily clenching her teeth at night, requiring her to get fitted for a dental retainer due to the hypertrophy of one of her jaw muscles. Additionally, she dealt with symptoms of unilateral neurogenic thoracic outlet syndrome (NTOS), unexpected fluctuations in heart rate and blood pressure, nausea, loss of appetite, overwhelming fatigue, and feelings of derealization. After four months of physical therapy, she consulted an orthopedist who suspected NTOS and recommended continuing therapy. Laboratory tests were also carried out to exclude any underlying physiological issues, including autoimmune conditions. Remarkably, following nearly five months of these distressing symptoms, an incident occurred one morning when she rolled over in bed and heard a distinct crack originating from either her shoulder or scapula. Almost immediately, her symptoms alleviated significantly. Her current physical therapist posits that this could have been due to an undiscovered rib subluxation impinging on her vagus nerve, leading to her previous symptoms. Fortunately, the majority of her autonomic symptoms have resolved, yet she continues to suffer from NTOS, along with persistent discomfort in her scapula and collarbone, which often feels misaligned. She also experiences notable tightness and pain in her trapezius and rhomboid muscles. Her therapist suggests that rib flaring may be contributing to her issues, but the sensations she's experiencing lead her to believe the situation might be more structurally complex. She seeks insight into what these persistent symptoms might indicate and the appropriate next steps she should undertake. Having been engaged in physical therapy for ten months and consulting multiple therapists without significant improvement—aside from the remission of her autonomic symptoms post-crack—she finds herself in need of guidance. There is no documented history of upper body trauma or diagnoses of connective tissue disorders, and all blood tests returned within normal limits. Any recommendations would be greatly appreciated. Thank you!
What Could Be Causing My Nighttime Smoke Smells?
For quite some time, I’ve been experiencing a peculiar issue where I suddenly detect the scent of cigarette smoke, seemingly from nowhere. The odor is so overwhelming that I feel as if I might choke on it, despite there being no one around me who is actually smoking. Strangely, this sensation occurs exclusively during the night and lasts only a few minutes. It appears that no one else in my household is aware of this phenomenon, which makes me think it might be something unique to me. I want to clarify that I have never smoked and have no intention of starting, just to put that out there! I find myself puzzled by what might be triggering this experience. Can anyone offer any insights or suggestions? I’m in my early twenties, a female dealing with anxiety and depression, but I’m not on any medication. Additionally, I do have a nasal polyp in my left nostril, if that might play a role in this situation.
