Concerns About Naegleria fowleri and Saline Rinses

7/23/2025, 2:40:19 AMMale25-34

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:

  1. Naegleria fowleri is rare and typically occurs in warm freshwater, but infection is very uncommon in healthy individuals.
  2. 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:

  1. 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.
  2. 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.
  3. Stay Hydrated: Drink plenty of fluids to help support your overall health and immune system.
  4. 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.

Surviving a Traumatic Incident: Seeking Help Years Later

30-Year-Old Male Height: 6'3" Weight: 270 lbs I don't smoke, but I use nicotine pouches. My AST levels are elevated at 60, likely due to years of alcohol consumption. At a party, I became a victim of a horrific act when a group decided it would be amusing to force bleach into my system after they had incapacitated me. This traumatic incident followed my unwitting consumption of a drug known as roofies. While under the influence and manipulated into drinking bleach, I declined medical assistance because they confiscated my phone and coerced me into sleep. I am fairly certain that I regurgitated some of the substance later on. Years later, I was made aware of this frightening experience when a friend shared the story. Sadly, it has already been eight years since that dreadful night. I am now looking for ways to ensure my health moving forward. What steps should I take to promote longevity, and which medical tests could I undergo to assess any potential damage to my organs?

M32 - Underwent a Head CT Scan Today

I completed a CT scan of my head today, and I’m grateful to report there’s no sign of bleeding or hemorrhaging. However, the physician informed me that I exhibit signs of "Generalized Cerebral Atrophy" that are greater than what is typically expected for my age group. Currently, I’m not experiencing any symptoms. The scan was prompted by an incident where I hit my head. I would appreciate any insights or information regarding this condition. I was discharged without further instructions, so I remain uncertain about the seriousness of the findings. Additionally, I was born two months prematurely—could this have any relation to my current situation? Thank you for your assistance.

Is Arthritis Possible at 26?

Lately, I've been feeling quite off, and I can’t pinpoint the cause. I’m a 26-year-old woman, standing at 5 feet 5 inches and weighing 178 pounds. For the past year to year and a half, I've noticed that my joints crack with even the slightest movements. After a full day at work where I'm on my feet, I experience significant soreness and discomfort. My feet hurt so much after those shifts that I sometimes wake up in the middle of the night just to go to the bathroom, and walking sends jolts of pain through my feet. It's really disconcerting, and I'm unsure what might be going on with my body. For context, I do have an IUD and have struggled with depression and OCD. Additionally, I've seen a notable weight gain over the last couple of years—approximately 50 pounds—but in the last three months, I’ve managed to lose about 15 pounds.

Mysterious Blister That Won't Heal

I'm a 36-year-old woman in my third trimester of pregnancy, and I’ve developed an unusual growth on my left pinkie finger that resembles a blood blister. This small lesion appeared about a month ago and has not shown any signs of improvement after a week. In an attempt to alleviate it, I used a finger lancet to lance the blister; it bled quite a bit and, although it closed up afterward, it looked even more inflamed. Interestingly, it doesn’t cause me any pain and feels soft to the touch. I examined it closely with a light source and noticed that it contains either a pocket or perhaps the opaque center indicates it's not a blister at all. Just yesterday, I lanced it again; it bled once more, closed up, and seems to have grown larger. I can gently squeeze it, and it leaks blood—useful for my finger prick tests since I have gestational diabetes. The appearance is not very appealing, presenting a purple and light red shade without clear borders, forming a lump about the size of a pea. I’ve done quite a bit of online searching and find myself more confused than before. Unfortunately, I don't possess health insurance and my financial resources are limited. Could anyone offer insights or advice about this situation?
