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!

Challenging Pain Journey with Nerve Involvement
Greetings! My name is Philip, and I recently celebrated my 20th birthday. Over the past several months, specifically since March, I have been grappling with significant pain affecting various parts of my body. This is my inaugural post, and I appreciate your patience with the length as I share the entire narrative and complexities regarding my situation. I want to split this information into two sections: Orthopedic Concerns (1) and Rheumatological Concerns (2). (1) To provide some background on my physical condition, I currently weigh 150 lbs and stand at 5'11" tall. I started weightlifting in October 2022, and within a few months, I significantly increased my weight and strength, jumping from 143 lbs to a peak of 167 lbs by late February to early March. My workout routines were intense, often lasting six days a week without breaks, leading to excessive volume, which I learned was not optimal. In late November, I began working in the kitchen doing various tasks, including dishwashing and heavy lifting, and ceased this employment in early-mid July. In mid-December, I also started practicing Jiu-Jitsu, which soon became one of my greatest passions, providing me mental relief during a challenging time. However, about a month into my Jiu-Jitsu training, I began experiencing discomfort in my left forearm and elbow, primarily exacerbated by certain weightlifting techniques and grappling. Despite the pain, I was reluctant to interrupt my activities, opting for regular doses of Ibuprofen instead. By March, the discomfort worsened, affecting both elbows: my left elbow experienced intense pain, and there was now tenderness in my right elbow. Activities became increasingly unenjoyable, and the pain became a constant companion, compelling me to consume significant amounts of Ibuprofen daily (between 600-1000mg). Reluctant to pause my routines, I finally sought orthopaedic advice when the pain became unbearable. After undergoing x-rays, my doctor diagnosed me with tendonitis and recommended rest. After approximately 10 or 11 days without exercise, my elbows felt much better, and I prepared to re-enter the gym. I believed I was starting off slow, but after just two sessions, the pain returned. Another extended rest didn’t yield the same relief this time, and I returned to the orthopaedic for further assistance, leading to a referral for occupational therapy, which proved ineffective. Matters escalated by early June as I experienced neck and upper back pain along with ongoing numbness and tingling in my hands and fingers. Sleeping at night became a challenge as I struggled to find a suitable position that wouldn't irritate my elbows or neck. My doctor theorized about potential nerve involvement and planned an EMG/NCS but decided to conduct further assessments of my elbows first. He prescribed me physical therapy for bilateral cervical radiculopathy and arranged MRIs for both elbows, along with a seven-day Medrol (methylprednisolone) steroid regimen. Simultaneously, my pediatrician ordered several blood tests to exclude autoimmune conditions; all results came back normal. The steroid pack provided substantial relief, especially for my elbows, but the benefits diminished shortly after completing the treatment, and my prior symptoms returned with a vengeance. The MRI revealed lateral epicondylitis (tennis elbow) with mild common extensor tendinosis and signs of ulnar neuropathy in the cubital tunnel on the left elbow. The right elbow reflected similar ulnar issues, leading my doctor to proceed with the NCS/EMG. The electrical study indicated that the nerves in my arms and hands appeared intact, but I likely have a pinched nerve at the C5-C6 level, creating irritation. An x-ray of my cervical spine showed normal results. After a subsequent MRI of the neck confirmed the absence of significant issues, my neck symptoms improved slightly, but I continued to struggle with my elbows and began feeling pain in my lower back and hips. Certain positions, especially while driving, triggered notable pain radiating into my legs and feet. A lumbar spine x-ray returned normal too, prompting an MRI for further investigation. I was also referred to a physiatrist skilled in acupuncture, who evaluated my symptoms and suggested a pricey elbow brace. Skeptical due to previous unsuccessful attempts with other braces, I expressed hesitation about purchasing it. A follow-up is scheduled for mid-September, with acupuncture appointments set for October. At this point, I continue to experience discomfort in my elbows, neck, upper back, and lower back/hips. The "shooting pain" has become infrequent, mostly resulting from prolonged poor posture. Although the meloxicam helps manage elbow pain, its effects do not extend to my neck or back. I follow a daily stretching plan and have shifted my PT visits due to a busy work schedule. Post-stretching provides some relief, but it doesn’t seem enduring. I still sleep with pillows underneath my knees and use a towel roll for neck support. I remain unconvinced that the issues with my elbows and back/neck are entirely separate, as I often feel tension radiating to my neck, tightness in my chest, muscle knots in my back, and discomfort flowing into my shoulders and triceps. I have an MRI for my lumbar region scheduled today (August 25), followed by an appointment with my spine specialist. (2) The reason for my rheumatology visit stems from a notable family history of autoimmune diseases such as Crohn's disease, rheumatoid arthritis, and sacroiliitis. After evaluations, I underwent blood testing and received a referral for an x-ray focused on my sacroiliac joints. My tests indicated elevated creatine kinase levels (218, exceeding the normal maximum of 200), while another assessed rheumatoid factor found normal levels. The HLA-B27 test for ankylosing spondylitis returned negative results. My recent follow-up with the rheumatologist five days ago revealed no significant abnormalities in the x-ray. Additional MRI tests for my sacroiliac joints and further blood tests for dermatomyositis and polymyositis were ordered. A follow-up appointment is scheduled in three weeks to discuss the findings of both tests. If anyone has insights or similar experiences to share regarding any of the topics mentioned, I would be incredibly grateful. I feel disoriented and eager to find ways to improve my situation, longing to return to activities I cherish. Thank you to anyone who takes the time to read my story or provide guidance; it truly means so much to me.
Could These Be Simple Ingrown Hairs Instead of Herpes?
(18M) Today, I underwent a swab test, and my physician expressed a strong belief that what I’m experiencing is merely an irritation from shaving, as I had groomed myself a few days earlier. I was initially quite anxious when I discovered some fluid-filled bumps at the base of my penis. In my nervousness, I ended up popping them, and they now resemble typical ingrown hairs. Still, I would appreciate hearing others' perspectives on the matter. My girlfriend has undergone two tests for herpes, both blood and swab, and both returned negative. I’ve faced a similar situation before, had it tested, and those results were negative as well, leading me to believe it’s not herpes. I’m curious to know your thoughts. Thank you!
Annoying Eye Twitch That I Can't Shake Off
Lately, I've been experiencing this strange twitch in my eye that makes it seem like I'm winking at people without even trying. It's becoming incredibly frustrating, and I honestly don't know what to do about it. Anyone else dealt with this issue? I'm 29, and this has been bothering me a lot lately!
Exploring Memory Concerns: Should I Discuss This with My Doctor?
I am a 33-year-old woman weighing 195 pounds and standing 5 feet 9 inches tall. I have been diagnosed with OCD, for which I currently take 75 mg of Zoloft, although I typically require a higher dosage. For the past several years, I have experienced increasing difficulties with word recall. This issue becomes more pronounced during moments of frustration or distress, yet it is a persistent challenge regardless of my emotional state. While no one in my family has been diagnosed with dementia, we do have a history of vascular disorders that have occasionally impacted brain health, including early strokes and aneurysms. This concern has been present for around six years, but I have noticed a steady escalation in memory lapses over the past three years. I began my OCD treatment about six years ago, and although I have increased my dosage to a maximum of 150 mg previously, I currently take 75 mg after consulting with my doctor due to its sedative effects. I also gave birth to my first child around the same time I started my medication, leading me to attribute my memory difficulties to the phenomenon often referred to as “mom brain.” My worries intensified lately, however, as I find myself forgetting common words in everyday conversations, such as "hairbrush" or "storage bin." Should this issue be discussed with my primary care physician? Is it merely a result of being a new mom, or is there something more serious at play? How pressing is it to schedule an appointment with my PCP to address these memory concerns? For context, my OCD tendencies do not revolve around health matters; my compulsions mainly focus on morality and interpersonal relationships.
Recurrent Internal Itching in Inner Thigh Since Childhood
Greetings. Since I was approximately 4 years old, I've been dealing with an unusual issue: a deep, itching sensation in my inner thigh, which feels as if it's originating from within the muscle itself. The only methods that seemed to provide any comfort were either patiently waiting for it to subside or applying pressure by gently tapping the area. This peculiar sensation ceased when I reached around 8 years of age, but now that I am 19, it has reemerged. Previously, I underwent several X-rays, and healthcare professionals assured me that everything appeared normal. In my childhood, my physical activity was quite limited; however, I have since adopted a more active lifestyle, yet the symptoms still intermittently arise. Should I be worried about this resurgence? Which type of medical practitioner would be most appropriate to consult regarding this condition?
