Concerns Regarding Legionnaire's Disease: Should I Seek Antibiotics?
I'm a 39-year-old male, standing at 5'10" and weighing around 180 pounds. Currently, I'm not on any medication, don't have a history of smoking, and consume alcohol only occasionally. I consider myself quite healthy; I engage in physical activity approximately three times each week and make an effort to maintain a nutritious diet, though I do indulge in cheat meals. Recently, I took a week-long trip during which I turned off my water heater and set it to vacation mode. Upon my return, I reactivated both the water heater and its valve. I used some hot water to clean the bathtub and tidy up around the house, and later, about five hours after turning the hot water back on, I took a shower. At that moment, I didn’t think about the potential for bacterial growth in the water tank. Now, I’m feeling anxious. What should I do next? Should I visit a walk-in clinic and request antibiotics to help prevent Legionnaire's disease, or would it be better to simply wait and see? I reside in the United States, just for context.

It's understandable to feel anxious about potentially harmful bacteria like Legionella after your recent trip and water heater use. However, there are some important points to consider regarding Legionnaire's disease and how to proceed.
Key Points:
- Legionnaire's disease is a type of pneumonia caused by the Legionella bacteria, often linked to contaminated water sources.
- It generally requires exposure to a significant amount of the bacteria, typically from sources like hot tubs, cooling towers, or large plumbing systems—not just from individual residential water usage.
- Symptoms include cough, fever, muscle aches, and shortness of breath, which often appear within 2 to 14 days after exposure.
Explanation: Given your description, it's reassuring that you consider yourself healthy and have no significant risk factors (like smoking or chronic illness). Simply resetting your water heater and using hot water in the home doesn’t inherently pose a high risk for Legionella unless you're experiencing symptoms.
Next Steps:
-
Monitor Symptoms: Keep an eye on your health over the next week. Look for any emerging symptoms such as fever, cough, or difficulty breathing. It might be helpful to note any specific changes in how you feel.
-
Hydration & Health: Maintain good hydration and continue your healthy habits. Eating a balanced diet and staying active supports your immune system.
-
Avoid Irrational Worry: It’s common to feel anxious about potential health issues, but unless you're experiencing symptoms, there's no immediate necessity to seek antibiotics. Overuse of antibiotics is generally discouraged to prevent antibiotic resistance.
-
Stay Informed: If you do develop respiratory symptoms or continue to feel unwell, then consider seeking medical advice. A healthcare professional can evaluate your symptoms and determine if further testing or treatment is needed.
-
Educate Yourself: Familiarize yourself with safe water heater maintenance practices to mitigate potential Legionella growth in the future.
By focusing on these steps, you can manage your anxiety more effectively while ensuring your health is prioritized. Let me know if you have any more concerns or if you need further information!

Guidance on Managing Concussion Symptoms
Hello, I'm a 32-year-old woman currently taking propranolol for postural orthostatic tachycardia syndrome (POTS). I also have Hashimoto's thyroiditis and am a smoker. Eight days ago, I experienced a head injury while driving my car. Approximately twelve hours later, I began to suffer from headaches alongside symptoms resembling the flu, including dizziness and nausea. Four days post-injury, I began to notice swelling in my face, which appeared similar to Bell's palsy. After a visit to the emergency room, I was informed that I have Bell's palsy, but a CT scan revealed no abnormalities. Since that time, my condition has deteriorated. While my headaches have been persistent, they are now more severe than they were initially. I was diagnosed with post-concussion syndrome, and the headaches are characterized by intense pressure. I also feel pressure in my temples, cheeks, and jaw. During a recent neuro examination in the ER, results were normal, but I was advised to increase my use of over-the-counter medications. Unfortunately, these do not seem effective and may even exacerbate my symptoms. I am experiencing significant anxiety, especially since I was reassured that it is not Bell's palsy. The continuing pressure in my face and temples and the relentless headache are quite frightening. Is it typical to experience a worsening of symptoms around the eighth day? How long might it take before I start to feel relief? Additionally, what strategies can I employ to manage the overwhelming sensations as if my head might burst? Thank you for your help.
Seeking Advice on Post-Surgery Pain
I'm a 35-year-old woman weighing 175 pounds and standing 5 feet 5 inches tall. I've been diagnosed with anxiety and depression, and my current medications include Klonopin and Wellbutrin. I do not smoke or consume alcohol, and I identify as Caucasian. I underwent surgery on April 10 and continue to experience significant discomfort. I am concerned about whether this level of pain is typical. My doctor reassures me that everything appears to be healing well and that post-operative pain can be expected. However, I sometimes feel as if I’m walking on rocky surfaces, yet the x-rays and the physical examination of my foot indicate no abnormalities. Additionally, it is painful to apply pressure on my big toe, regardless of the type of shoes I wear. I have a vacation planned for next week, and I am anxiously worried that it will be spoiled by my current condition. I will include a description of the procedure I had in the comments for reference. I just feel overwhelmed because it often seems that complications arise whenever I undergo a medical treatment. Any insights or advice you could offer would be incredibly appreciated. Thank you kindly in advance for your help!
Variable Redness Around Recent Injury
46-year-old female, weighing 140 lbs, diagnosed with EDS and POTS, experiencing perimenopause, currently on low-dose birth control, refraining from alcohol consumption, uses medical marijuana. On Friday evening, while preparing an old area rug for disposal, I accidentally scraped my ankle/shin with a utility knife. The blade was freshly changed, resulting in a clean cut approximately half an inch in length. I rinsed the cut with water, treated it with hydrogen peroxide (as it was my only option aside from scented soap), applied polysporin, and sealed it with a bandaid, then resumed my activities. By Saturday morning, my ankle felt somewhat tight, exhibited minor swelling, and exhibited an emerging red spot that progressively intensifying throughout the day. To be cautious, I planned to visit urgent care if the condition remained unchanged or worsened by morning. However, upon awakening on Sunday, I noticed noticeable improvement; most of the redness had subsided, swelling and stiffness had diminished, so I opted against a medical visit. Later that evening around 5 PM, when I went to redress the wound, I discovered that the redness had reappeared and had increased in size. The area adjacent to the cut is somewhat tender to touch, but I am not experiencing any significant pain, discharge, or unusual odor; it doesn’t feel notably warm, perhaps just slightly. I have noticed occasional itchiness but it is not persistent. Upon inspection, the cut appears to be deeper than originally assessed, potentially requiring stitches. Additionally, my air conditioning is malfunctioning, leaving my home at approximately 82 degrees, which may contribute to the situation.
Understanding Noncompaction Cardiomyopathy: Insights on EF Levels
A 36-year-old woman weighing 132 pounds is currently only taking a multivitamin and Restasis. Previously, she was prescribed Plaquenil and Meloxicam; however, she stopped these medications two months ago at the request of her rheumatologist, who wants to prioritize addressing her heart condition first. She has been diagnosed with Sjogren's Syndrome, Polycystic Ovarian Syndrome, and Postural Orthostatic Tachycardia Syndrome. She is uncertain about the implications of her cardiac MRI results. Seeking clarity, she expresses a desire to avoid misinformation from online sources. Her pulmonologist referred her to a cardiologist due to symptoms including chest pain, palpitations, and episodes of shortness of breath. Following this referral, the cardiologist recommended a cardiac MRI and has suggested consulting with the Cleveland Clinic for further evaluation, though specifics on the reasons for this referral remain vague, mentioning only that there may be some concerns. The report from her cardiac MRI indicates "findings consistent with cardiomyopathy with increased trabeculations," a condition more commonly known as noncompaction cardiomyopathy, as per the Peterson criteria. The report specifies her left ventricular ejection fraction (EF) at 52 and her right ventricular EF at 49, both of which are categorized as "low normal."
Guidance on Unexpected Hand Swelling
Hello! I’m a 24-year-old female currently taking birth control along with medications for depression (Venlafaxine) and ADHD (Vyvanse). I reside in Canada. Yesterday, I attended a birthday celebration for my nephew at a public indoor swimming facility. The day was pretty standard, consisting mainly of enjoying some waterslides and keeping an eye on the kids. However, upon returning home, I started to feel discomfort in my left hand. By 8 PM, the pain had intensified to the point where I couldn't bend my fingers at the knuckles. Today, my left hand remains both painful and swollen, although I've noticed the swelling doesn’t bother me when it's resting in a neutral position. I’ll share images in the comments for reference. After doing some digging into potential causes, I’m starting to think this might be a kind of injury or perhaps a sprain. I can't recall any moment when I hurt myself or felt any pain before this incident. Some friends are urging me to visit the emergency room, but I believe that could be an overreaction. I would appreciate any advice!
