Concerns About Balamuthia mandrillaris Exposure

8/31/2025, 11:50:37 PMMale25-34

At 26 years old, I find myself in good health but increasingly anxious about the potential danger posed by Balamuthia mandrillaris, an uncommon amoeba. Recently, I put a book on my dresser that had been tucked away beneath a friend's table for six months, likely accumulating a lot of dust. This book ended up positioned close to my toothbrush, which was angled toward it. While brushing my teeth, I focused on my sensitive gums, which sometimes bleed, using only toothpaste—no water was involved in this process. Though I do get my toothbrush wet each day during my shower and also utilize mouthwash, I can't shake the worry that the amoeba could have transferred from the book to my toothbrush. Could it infect me through my gums and possibly travel to my brain? I'm especially troubled by the thought of it potentially surviving in mouthwash. Given the serious implications of this amoeba and its ability to cause brain infections, how significant is the risk? Should I consider seeking dental care or testing regarding my gums?

Your concerns about Balamuthia mandrillaris and its potential risks, especially in relation to your oral hygiene, are understandable. However, the risk of infection in your specific situation is extremely low.

Explanation:

Balamuthia mandrillaris is a rare amoeba that can cause serious infections, primarily through exposure to contaminated water or soil, particularly when it enters the body through the nasal passages or open wounds. It does not transmit effectively through everyday objects or through the mouth in the way you described. While you mentioned that your gums are sometimes sensitive and can bleed, the likelihood of the amoeba transferring from a dusty book to your toothbrush, and subsequently entering your bloodstream or brain through your gums, is highly improbable.

Additionally, mouthwash typically contains antibacterial ingredients that would further reduce the risk of any pathogens present.

Next Steps:

  1. Reduce Anxiety: Try to focus on the low likelihood of infection from your described scenario. Understanding that Balamuthia mandrillaris infections are extremely rare may help alleviate your concerns.

  2. Oral Hygiene: Continue your regular oral hygiene routine, including using mouthwash. Ensure your toothbrush is clean and stored properly to limit exposure to dust or contaminants.

  3. Monitor Symptoms: If you notice any signs of gum infection (such as increased bleeding, swelling, or pain) or any unusual symptoms (like headaches, fever, or neurological changes), you can consider reaching out to a dental professional for advice related to your gums.

  4. Address Anxiety: If your anxiety about this or similar health concerns persists, consider discussing it with a mental health professional who can help you manage these feelings effectively.

Rest assured, there is no immediate cause for concern regarding Balamuthia mandrillaris based on your description. If you have further questions or need reassurance, feel free to ask.

Bleeding Concerns with IUD and Yeast Infection Treatment

I’m a 20-year-old female, standing at 5’4” and weighing 155 pounds. Hello everyone! Approximately three weeks ago, I had the Kyleena IUD placed, and everything felt fine afterward—I can still feel the strings. I noticed some mild spotting that was brown for about a week, followed by my menstrual period, then continued with light spotting. Recently, I suspect that I might have developed a yeast infection, which I am currently addressing using Monistat 7. I applied the first dose yesterday. To clarify, I am certain that I am not dealing with a sexually transmitted infection. However, I’ve observed an increase in bleeding, significantly more than what I’ve experienced before. The blood appears to be light red, and I would compare the amount to the lightest day of my period. I could comfortably go an entire day without needing to change my pad, though I still do it for hygiene reasons. Is this a common occurrence? Most of the bleeding took place this morning after I woke up, coinciding with the Monistat cream leaving my body. Under what circumstances should I seek medical advice regarding this issue instead of waiting to see how the treatment progresses?

Understanding Recurrent Symptoms: Are They Histamine-Related?

Hello, health professionals, I am seeking your expertise regarding a variety of symptoms I have been experiencing intermittently over the years. While they appear linked, I'm having difficulty pinpointing their root cause. **Personal Summary:** - 27 years old, Female - Non-smoker (formerly vaped for about eight years, cessation initiated two years ago) - No diagnosed autoimmune conditions - Background of anxiety (which might exacerbate some symptoms, though it doesn't account for all) - Currently taking Flonase and a multivitamin **Skin Reactions:** - I've dealt with recurring itchy rashes and hive-like bumps since childhood. They manifest suddenly and usually resolve without intervention. - These rashes are often itchy, can be raised, and tend to appear sporadically without identifiable triggers. - Antihistamines provide consistent relief, leading me to suspect a role of histamines in these eruptions. - These episodes do not align with typical contact allergies or classic food allergies. - They can happen multiple times daily, and I've often dismissed them as merely anxiety-related rashes. - Sometimes the itching precedes the visible rash, while other instances present with a red, inflamed area that stirs inquiries about my well-being from others. **Foot Discomfort:** - Over the last few years, I’ve encountered severe itching on the soles of my feet. - These episodes typically include small pale or white spots with redness surrounding them, occasionally featuring a red center. - Itching intensity can be overwhelming, yet these lesions usually arise suddenly, - They frequently improve upon avoiding scratching and may resolve within a range of 30 minutes to two days. - The first episode was triggered after swimming in a freshwater lake, though I’ve also experienced it while wearing specific footwear like Crocs or boots, but not consistently. - Certain events coincide with my typical skin rash, hinting at a potential systemic condition rather than merely a localized issue. - The symptoms do not mirror those of warts, ringworm, or fungal infections. **Ear and Sinus Issues:** - Itchy ears have been a recurring issue for the past few years; I initially attributed it to overly aggressive cleaning with cotton swabs, which I realize is harmful. - I have a history of chronic sinus problems, including post-nasal drip and regular ear infections. - The inflammation appears to flare up sporadically rather than constantly. - Recently, I experienced a painful ear issue that began with what I thought was a pimple. The next day, my ear was swollen. After visiting a clinic, I was diagnosed with a double ear and sinus infection, treated with antibiotics. My pain persisted, leading to a follow-up with my primary care physician, who prescribed Flonase and noted ongoing nasal inflammation. Missing doses led to increased ear discomfort, prompting me to take Flonase more regularly. Unfortunately, a recent flare of swelling and discomfort in my ear led me to consider consulting an ENT specialist. **Gastrointestinal Symptoms:** - I was diagnosed with gastritis through an upper endoscopy procedure. - Testing for H. pylori returned negative. - I've since developed food sensitivities and gastrointestinal discomfort not previously experienced. - I saw significant improvement after removing gluten and dairy from my diet, with tests for celiac disease yielding negative results. - Symptoms tend to flare up in response to stress or specific food intake rather than being a constant presence. **Additional Context:** - A history of childhood asthma (now occurs infrequently) - Sensitivity to heat - Past instances of feeling lightheaded, resembling vasovagal symptoms, alongside vertigo - Symptoms across various systems often flare together, but not in every instance - While my anxiety can intensify symptoms, both antihistamines and diet modifications have had notable positive effects **My Inquiry:** While I don’t wish to self-diagnose, I'm curious if my range of symptoms might suggest: - Histamine intolerance - Mast-cell overactivity (not necessarily MCAS, but an increased reaction) - Physical or contact urticaria I'm primarily seeking: - Recommendations for a suitable specialist - Insight on whether this symptom pattern fits a recognized mechanism - A clearer understanding of what warning signs to be concerned about **Summary:** I contend with a long-standing pattern of episodic itchy rashes and hives, significant but transient foot itching along with bumps, persistent ear irritation coupled with sinus problems, and gastritis accompanied by food sensitivities that improved on an elimination diet. Antihistamines aid multiple symptoms. Could this suggest underlying histamine-related issues manifesting across multiple systems rather than in isolation?

Chronic Joint Pain Since Childhood

Since I was eight years old, I’ve endured intense and persistent pain in my joints. Initially, the discomfort was primarily in my knees, characterized by a sharp sensation right beneath the kneecap. As someone on the autism spectrum, I often visualize a strange, soothing thought: the idea of removing my kneecap and using an ice cream scoop to relieve the pressure underneath it. My parents sought help from several medical professionals, all of whom attributed my symptoms to growing pains. I even underwent cancer screenings at the age of nine because doctors felt my level of discomfort was excessive for mere growing pains. At school, I frequently had to wear dual knee braces. When I turned 14, I had a CT scan, but the results were inconclusive; doctors continued to insist it was just growing pains. At 18, I had an X-ray that also revealed nothing abnormal. Now at 20, my joint pain persists and is progressively worsening. My hands now ache in addition to my knees, and on particularly bad days, the pain radiates down to my ankles, making walking and sleeping almost impossible for half the week. The discomfort has entirely hindered my ability to work. My family and I strongly suspect that I may have some form of arthritis, but I struggle to convince the medical community of this due to my young age. My father, who suffers from arthritis himself, often empathizes when I express my pain, telling me, "that sounds familiar." I have broken down in front of numerous doctors, pleading for assistance, yet I consistently leave without answers, only to be scheduled for more scans that come back normal. The medical care I have received thus far has been far from satisfactory; for instance, I was prescribed eye drops that nearly resulted in serious damage to my vision when I consulted an eye specialist. This is just one of many frustrating experiences I’ve faced. I feel completely overwhelmed and in agony, and I have no way to reach out for specialized medical help since my only means of transportation is my father, who is also afflicted by arthritis. I feel lost and in deep pain without a clear path forward.

Seeking Guidance on Persistent Chest Discomfort After Extensive Testing

I'm a 43-year-old male, standing at 5'11" and weighing 180 pounds. My journey began around March to April of 2025 when, despite regularly hitting the gym four times a week, I was struck by severe chest pain along with frequent belching and a tight feeling in my diaphragm. At times, the pain became so intense that I feared it might be a heart attack. **Medical History:** In May 2019, I received a diagnosis of **PVS** and have since been under the care of a cardiac electrophysiologist. Upon experiencing these new symptoms, I consulted my EP, who conducted an EKG right then and set me up with a 7-day heart monitor. The results showed no irregularities. Subsequently, I was directed to a cardiologist, who carried out both a **stress test** and an **echocardiogram**, both of which yielded normal findings. Afterward, I returned to my primary care physician, who speculated that my gallbladder might be involved. An **ultrasound** was performed but revealed no issues. I then requested a **chest X-ray**, which also came back normal. My PCP then considered the possibility of a **hiatal hernia** and referred me to a gastroenterologist; unfortunately, that appointment took almost **five months** to materialize. In the meantime, my symptoms persisted, prompting me to cease weightlifting and switch my focus to **cardio and running**. Surprisingly, these activities didn’t exacerbate my symptoms, though the chest pain remained constant. When I finally saw the gastroenterologist, they suggested an **upper endoscopy**, which took another roughly three months to arrange. During this procedure, I was diagnosed with **Eosinophilic Esophagitis (EOE)**, a condition I had not previously experienced. The doctors also placed a pH monitoring device for acid reflux assessment, which indicated **no unusual acid exposure**. Following this, I began a treatment plan that included a swallowed steroid inhaler and an increased dosage of **omeprazole**. Sixty days later, I underwent another endoscopy, which showed that the EOE had largely resolved, with minimal residual symptoms. Unfortunately, my chest discomfort persisted without any improvement. It has now been about **a year** since these issues emerged, and I still have not found substantial relief. A recent chest MRI completed at a dedicated imaging center revealed no abnormalities. I entertained the idea of **costochondritis**, but again, the MRI did not support that hypothesis. The only minor relief I find comes from consciously pulling my shoulders back and expanding my chest. I continue to experience discomfort around my **diaphragm** and tenderness in the area of the **xiphoid process**. My PCP prescribed a steroid pack, which was somewhat beneficial for the pain but failed to alleviate the pressure or constant discomfort. At this juncture, I feel quite lost and uncertain about my next steps. I would greatly appreciate any insights or experiences from others who have faced similar issues. Additionally, if there are any physicians here willing to offer advice, I am open to traveling to find the answers or relief I'm desperately seeking.

Understanding Mild Uncomplicated Diverticular Disease

I am a 29-year-old female, standing at 5'7" and weighing 130 pounds. Recently, a CT scan revealed that I have mild diverticulitis. About a week ago, I experienced significant discomfort, particularly in the pelvic region, along with pain in my right leg and hip, and some mild discomfort on the left side. After undergoing a CT scan, which confirmed the presence of mild diverticular disease, I was surprised that no one from my medical team provided any follow-up or acknowledged the condition. My blood tests returned normal results, and I was discharged without further information. While the pain subsided after about three days, it has unfortunately reappeared four days later. Is this something I should be worried about? What does this mean for me? I had a colonoscopy around 11 months ago, which indicated no issues.
