Concerns About Amoeba Infection
I'm feeling extremely anxious and need some guidance. Recently, I've sustained an injury on my body that is currently covered with two adhesive bandages. I sat down forcefully on a couch in Arizona, where the temperatures frequently reach between 106°F to 110°F, and the environment remains quite arid. Notably, this couch had been damp last week but has since dried out. I observed a hint of pink on the second bandage, which raises my concerns that part of my injury may have become exposed. My primary worry revolves around the potential risk of an Acanthamoeba infection, as I’ve come across information indicating that such infections can occur through open wounds and polluted water. In response, I took precautions by cleaning the wound with antimicrobial wipes, alcohol, and applied a liquid bandage, followed by a fresh dressing. As there has been no moisture on the couch for several days, I'm uncertain if the previous dampness contained harmful microorganisms. Is it conceivable that my wound could only be exposed to the cutaneous form of the amoeba rather than the granulomatous amoebic encephalitis (GAE)? Is there a possibility of the amoeba traveling from my leg to my brain through the wound? Furthermore, can Acanthamoeba persist on a dry couch given these high temperatures? Could it have somehow made its way into my wound? I'm overwhelmed with worry and fear about the potential for a serious infection. - Am I facing a legitimate risk of Acanthamoeba infection? - What symptoms should I monitor as my wound heals? - Is it crucial for me to consult a doctor immediately, or can I opt for a telehealth appointment?

It's completely understandable to feel anxious about your injury and the potential risks associated with infections, especially when you've researched something as serious as Acanthamoeba infections. Let's break down your concerns clearly.
Key Points:
- The risk of Acanthamoeba infection from your situation is generally low, especially since the conditions are less favorable for the amoeba in dry environments.
- Monitoring symptoms as your wound heals is essential.
- Consulting a healthcare professional is advisable, but the urgency depends on how your wound progresses.
Explanation:
Acanthamoeba infections are primarily associated with exposure to contaminated water, commonly linked to contact lenses or injuries sustained in water. The risk from your specific scenario (a wound that sat on a couch) is lower, particularly since the couch has been dry for several days. Acanthamoeba thrives in wet environments, and dry conditions, along with high temperatures, would hinder its survival.
Regarding your concerns:
- The possibility of developing a cutaneous infection from Acanthamoeba due to a dry couch is minimal.
- It is much less likely that Acanthamoeba would travel from your leg to your brain. GAE typically occurs with exposure to contaminated water, not through typical skin injuries.
Next Steps:
-
Monitor Your Wound:
- Watch for signs of infection such as increasing redness, swelling, warmth, or discharge from the wound.
- If the pink you noticed on the bandage is from mild irritation, that’s often normal. Keep the wound clean and dry.
-
Self-Care:
- Continue cleaning the wound gently with mild soap and water instead of alcohol, if possible, to avoid irritation.
- Change the dressing regularly to maintain cleanliness while ensuring it isn’t too tight (which can hinder healing).
-
Assess Symptoms:
- Look out for fever, persistent pain, or any unusual changes around the wound. If you experience any severe symptoms (like significant swelling or discharge), it would be wise to seek immediate help.
-
Consulting a Professional:
- If your wound shows improvement, a telehealth appointment can be a convenient option. However, if things worsen, don't hesitate to seek in-person medical attention.
It's normal to feel a bit overwhelmed, but focusing on wound care and monitoring your symptoms will help manage your anxiety. Don't hesitate to reach out if you need support or further guidance!

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.
24M | Unexplained Fainting Incident
**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?
Swelling Beneath My Chin Near the Jawline
18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.
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
