Concerns About Naegleria fowleri and Saline Rinses
While I’m not panicking, I did have a moment of concern after recently diving into a river without adequately pinching my nose—I was just being playful for some photos! The impact was quite strong, and I can definitely say that water surged up my nostrils, likely at around 72°F. The river current is still active, and the water was deep, but it is July after all. If Primary Amoebic Meningoencephalitis (PAM) is what awaits me in the end, then I accept it. Swimming is something we enjoy. However, I am curious about whether using a saline rinse or a Neti pot might help to flush out any potential amoebas that may have entered my nasal passages. I would greatly appreciate any insights anyone might have on this topic!

It's completely understandable to have concerns after swimming in a river, especially regarding Naegleria fowleri and Primary Amoebic Meningoencephalitis (PAM). However, there are some key points to consider, along with proactive steps you can take to ease your mind.
Key Points:
- Naegleria fowleri is rare and typically occurs in warm freshwater, but infection is very uncommon in healthy individuals.
- The water temperature you mentioned (72°F) is within the range where this amoeba can thrive, but simply being exposed does not mean you will get infected.
Explanation: Naegleria fowleri is most often associated with activities that allow water to enter the nasal cavity from warm bodies of freshwater, particularly when the water is forced up the nose, as can happen during diving or water sports. However, the actual risk of infection is extremely low, especially if you do not have any symptoms.
When it comes to using a saline rinse or Neti pot, these can indeed help clear your nasal passages and may provide some peace of mind. Saline rinses are useful for flushing out irritants and can help maintain nasal health. However, it's crucial to ensure that you use sterile or distilled water for the rinse to avoid any potential risk of introducing infections.
Next Steps:
- Use a Saline Rinse: If you feel comfortable, use a saline nasal rinse or Neti pot with sterilized or distilled water to help clear any potential irritants from your nasal passages. Do this a few times over the next couple of days.
- Monitor Symptoms: Keep an eye on any symptoms over the next 1-2 weeks. If you develop severe headaches, fever, neck stiffness, or any other concerning symptoms, take note of them.
- Stay Hydrated: Drink plenty of fluids to help support your overall health and immune system.
- Practice Preventative Measures: For future activities, consider using a nose clip if you plan to dive or swim in freshwater to reduce the risk of water entering your nasal passages.

Strange Stomach Sensation Leading to Waking Up
Greetings. I'm a 36-year-old male, standing at 172 centimeters and weighing 90 kilograms. I don't take any medications, nor do I smoke. I've been living with diastasis recti for several years now, and I may also have irritable bowel syndrome (IBS). Additionally, I deal with fatty liver and kidney stones, though I assume these last two conditions are not related to my current concern. Occasionally, I experience a peculiar sensation that jolts me awake; it feels like a quick pulsing in my stomach. I’ve noticed it tends to affect the left side when I’m lying on my left side and the right side when on my right. Remarkably, it can occur even when I’m on my back. This strange feeling often escalates into a surge that fully rouses me. Alongside this, I sometimes feel prickling sensations throughout my body and fleeting lightheadedness. When this sensation disturbs my sleep while I’m turned to my side, shifting onto my back or the opposite side might alleviate it, but not always. In instances where I awaken while lying on my back, I discovered that gently pressing my hands on either side of my stomach can help, as can rising to a sitting or standing position. However, during my last two episodes—one a couple of weeks ago and another tonight—those techniques weren’t effective right away, which made me feel a bit anxious, prompting me to seek advice. Does anyone have insight into what might be going on? By the way, I’ve undergone routine ultrasound examinations of my abdomen by two different physicians during check-ups, both of whom assured me that everything appears normal, including my abdominal aorta and internal organs. They didn’t identify any issues at that time.
Understanding Tuberculosis Exposure Risk
A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.
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!
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.
