It's understandable to feel anxious about the possibility of encountering a brain-eating amoeba, especially after water has entered your nose. However, it's important to put your concerns into perspective. While these amoebas (Naegleria fowleri) do exist in certain warm freshwater environments, the risk of infection from tap water exposure is exceedingly low, particularly in well-maintained municipal water supplies.
Understanding Your Situation:
- Risk of Infection: Naegleria fowleri is primarily contracted through warm freshwater sources, such as lakes, hot springs, or poorly maintained swimming pools. The likelihood of getting infected from regular tap water is very low.
- Symptoms Timeline: Symptoms of naegleriasis typically appear within 1 to 12 days after exposure. Since it has been 72 hours since your exposure and you have not experienced any symptoms, this is a positive sign.
Next Steps:
- Monitor for Symptoms: While the likelihood remains low, keep an eye out for symptoms such as severe headache, fever, nausea, vomiting, stiff neck, or changes in mental status. If you notice any of these develop, seek help immediately.
- Ease Anxiety: Practice relaxation techniques to help manage your anxiety, such as deep breathing exercises, meditation, or gentle physical activity.
- Stay Informed: Educate yourself about Naegleria fowleri from reliable sources like the CDC to better understand the actual risks and symptoms associated with this infection.
It's important to remember that feeling anxious is natural, but most exposures to nasal water will not result in illness. Focus on self-care and monitor how you feel, and rest assured that your chances of contracting an infection from this incident are very low. If you need further reassurance or symptoms arise, consider discussing your concerns with a healthcare provider.

In the last few days, I have observed a small amount of cloudy discharge emerging from my incision site. Recently, I noticed what appears to be pus leaking from the area. While there is no significant pain, I do feel a mild soreness when I touch or move the site. I have not experienced any fever or chills, and there’s no unpleasant odor coming from the wound. Should I continue to clean the area with soap and water, or is it advisable to seek medical attention at the emergency room for further evaluation?
Identifying a Mysterious Brown Circle on My Scalp
Age: 21 Gender: Female Height: 5'4" Weight: 175 lbs Ethnicity: White (Scottish/Irish) Location: California Current Medication: Testosterone injection administered subcutaneously in the thigh While I was having my hair dyed blue, my girlfriend noticed a perfectly circular brown mark on my scalp. It resembles a circle that appears to have been made with a brown marker. The size of the ring is similar to my thumb’s tip and contrasts sharply with the lighter shade of my scalp. There is no evidence of hair thinning or loss around this circle; we only discovered it because we were parting my hair. I’m curious if this could be connected to the brain fog or headaches I’ve been experiencing lately. I looked online, and while ringworm was suggested, it doesn’t match my symptoms since there are no bald patches or flaky skin. I’m open to answering any additional questions to help clarify this situation, as it's causing me some concern.
Should I Seek Medical Attention for a Possible Spinal Injury?
Greetings! I’m a 20-year-old male, and while I’m not overly anxious about my situation, I've been experiencing enough discomfort to consider it. Three days prior, I went snowboarding and attempted to navigate a box, which is essentially a flat metal structure with a slight ramp at the end. Unfortunately, I lost my balance close to the end of the box and landed squarely on my backside. This caused my back and head to make hard contact with the ground. At first, I didn’t perceive much pain in my back or head; instead, the primary source of pain seemed to be my rear, which felt as if it had developed a noticeable lump. However, I dismissed it at the time. The following day, the soreness persisted, alongside generalized discomfort throughout my upper body. Every time I coughed, I felt pain that radiated from my neck down to my abdomen, which was tender to the touch. I asked my girlfriend to check for any visible injuries, and although my butt showed no bruising, I did notice around five bruises along my spine. I’m questioning whether I should consult a physician. I usually avoid going to the doctor unless absolutely necessary, having only visited twice in the last four years (excluding vaccinations during my teenage years). I tend to prefer toughing things out to save on medical expenses, but if the situation warrants it, I wouldn’t hesitate to seek help as I did last year for an ear infection. What do you think – should I consider getting checked out?
Seeking Insight on Abnormal Neuroimaging Results
A 42-year-old female, standing 6 feet tall and weighing 194 pounds, has been grappling with cognitive challenges for over three years. She has a clinical history that includes a diagnosis of Bipolar II disorder coupled with generalized anxiety, which she manages effectively through a regimen of an antidepressant, a mood stabilizer, and medications for anxiety. Currently, she is under the care of her fifth neurologist in the Boston region. An FDG-PET scan revealed a significant decline in metabolic functions, showing a 30-40% reduction within the left parietal lobe and a 20% decrease in both mesial temporal lobes. As part of her evaluation, a lumbar puncture was performed to assess amyloid and tau protein levels, with results coming back negative. Although a radiologist recommended pursuing an amyloid PET scan to gain further insights, her neurologist has declined this option. Despite the neurologist's suggestion that her indications might fit into the Functional Neurological Disorder (FND) category, she remains unconvinced and believes there must be an identifiable underlying cause for her symptoms and the irregularities observed in her scans. She is seeking advice on the next steps to take in pursuing a clearer diagnosis or understanding of her condition.
Worsening Memory Problems Over Time
Age: 25 Weight: 175 lbs Current Medications: Modafinil (200mg); Lexapro (10 mg); Lamotrigine (100mg in the morning + 100 mg in the evening); Cyproheptadine (4 mg); Vraylar (1.5 mg) Supplements: Iron; Vitamin B12; Vitamin D; Salt tablets Health Background: Long-standing, stubborn migraines (resolved as of May 2025, originally began in April 2016); Depression (currently very stable); Attention Deficit Disorder (ADD) (experimented with various stimulants with no improvement in memory); Chronic fatigue syndrome (developed a few years after memory problems began). I possess a documented medical history concerning my memory challenges. Around 2012, I underwent neurological evaluations that included an IQ assessment. The clinician indicated that my memory performance was particularly low, affecting my overall IQ representation, while I scored at or above average in most other areas. In approximately 2017, a neurologist referred me for a neuropsychological evaluation. Unfortunately, the results were deemed "inconclusive" due to inconsistent findings, with the provider stating my memory levels mirrored the previously reported low scores. Fast forward to 2023, when I underwent another neuropsych evaluation, which indicated my working memory was significantly below the average range. The clinician expressed uncertainty regarding effective treatment options for my memory issues, suggesting avenues such as ADHD medications, stress management, enhancing sleep quality, and mental health support—areas which I have pursued or tried to improve. Here is a summary of the strategies and treatments I've explored: - **Sleep Study**: Diagnosed with mild sleep apnea when lying on my back, although I typically sleep in other positions. - **Antidepressants**: Tried various types repeatedly, yet without noticing any significant changes. - **Occupational Therapy**: Participated but found it more stressful than beneficial. - **Speech Therapy**: Benefitted somewhat, yet it didn't meet my expectations, though I continue to use some of the techniques learned. - **Digital Notes**: Attempted to record important information on my phone, but due to many lists, vital entries often get lost. - **Memantine**: Prescribed by my neurologist as a last resort, based on its reported effectiveness in elderly patients for pain management; however, I did not observe any memory improvements while on this medication. - **Nutritional Supplements**: Regularly take Vitamin B complex, fish oil, flaxseed oil, and various other potential memory enhancers. Additionally, family history reveals that my brother, sister, and paternal grandmother have also faced memory-related issues throughout their lives. Unfortunately, several neurologists have declined to treat me, citing my youth and existing diagnoses of depression and ADD as indicators of instability rather than addressing my memory concerns. Moreover, I am anxious that my past struggles with chronic pain could have exacerbated my memory problems. Any insights or suggestions to tackle these ongoing challenges would be greatly appreciated.
