Concerns about Flesh-Eating Bacteria
I'm a 19-year-old, standing 5'4" tall and weighing 135 lbs, generally maintaining good to slightly above-average health. To my knowledge, I do not face any immune system issues. I have a long-planned trip to a lake with friends that has been in the works for several months. Recently, while out for a run, I tripped on pavement and scraped my shoulder. The abrasion is only a few inches in length and superficial, and it has started to heal with mostly dry scabs forming. I’m eager to enjoy swimming this weekend since this outing has been anticipated for such a long time, and I’m uncertain when I might have a similar opportunity. However, I've heard some discussions regarding the presence of flesh-eating bacteria in lakes. What is the level of risk associated with Lake Ontario regarding this issue? Furthermore, should I be unfortunate enough to contract it, what are the odds of facing serious health complications or even mortality?

It's understandable to be concerned about potential health risks from swimming, especially with your recent scrape. Wounds can lead to infections, but the risk of contracting flesh-eating bacteria from lakes, including Lake Ontario, can be managed with proper precautions.
Main Points:
- Risk Assessment: The overall risk of contracting flesh-eating bacteria in lakes is relatively low for healthy individuals, but it's not zero—especially if you have an open wound.
- Precautionary Measures: Taking specific steps can help minimize your risk and protect your health while still enjoying your trip.
Explanation:
Flesh-eating bacteria, or necrotizing fasciitis, are rare but can exist in warm freshwater, especially during warmer months. These infections typically occur in individuals with weakened immune systems or significant other health vulnerabilities. Given your generally good health and lack of immune issues, your risk is lower; however, an open wound can still be a potential entry point for bacteria.
Prioritized Next Steps:
-
Protect Your Scrape: Cover your wound with a waterproof bandage to keep it dry and clean. This reduces the chance of bacteria entering through the scrape while swimming.
-
Avoid Murky Water: Choose swimming areas that are clear, as cloudy or murky water can have higher bacteria levels. This applies especially to areas with many people or wildlife.
-
Monitor for Symptoms: After swimming, check your wound regularly and watch for any signs of infection, such as increased redness, swelling, warmth, pain, or discharge.
-
Enjoy the Trip: If everything looks good and you feel healthy, going for a swim can be a fun experience! Just ensure that you follow the precautions mentioned.
If you do develop any concerning symptoms after your trip, it’s important to seek medical evaluation promptly. Enjoy your outing with friends! Stay safe and have fun!

Unexplained Bruising and Intense Itching
Hello, I’m a 20-year-old female, standing at 5 feet 2 inches and weighing 135 pounds. Recently, I have been experiencing intense itching that has resulted in significant bruising on my skin. Currently, I’m on several medications including spironolactone (which I haven’t taken for the last two weeks), Effexor, Aimovig, Wegovy, and Linzess. I do not use tobacco or consume alcohol. Apart from experiencing a generally sluggish digestive system, I have no pre-existing health issues. However, my family medical history indicates occurrences of Multiple Sclerosis, Hashimoto’s disease, diabetes, and eczema. The itching has become severe, leading to large bruises forming on my body. I consulted a virtual urgent care service, which advised me to visit the emergency room to check for potential blood clots or internal bleeding. Upon arriving at the ER, I underwent various tests, and I noticed that my resting heart rate has been notably elevated between 120 and 140 beats per minute, though I am uncertain if this is a new development. Eventually, I was discharged without any conclusive information, except with the advice to refrain from scratching. I have shared images of the tests conducted during my visit.
Understanding Prednisone Usage and Withdrawal
A 38-year-old woman, measuring 5’10 and weighing 125 pounds, with no smoking or drinking habits and a background of autoimmune disease, encountered a viral infection in December. In response to her condition, a specialist recommended a tapering regimen starting with a 40mg dose of prednisone for five days, followed by a gradual reduction through 30mg, 20mg, and 10mg over a total period of 20 days. After completing the course and halting the medication, she experienced severe symptoms approximately 36 hours later, including intense vomiting, debilitating headaches, and widespread pain throughout her body. Any physical contact provoked discomfort, leaving her in distress. Unable to reach her original provider, she consulted another physician who prescribed a lower dosage of 4mg of prednisone, instructing her to decrease the amount by 1mg every three days. Remarkably, she felt relief upon returning to the 4mg dose. However, she expressed concern regarding the potential effects when she ultimately weans off the medication entirely. She is seeking guidance on whether this method of tapering is typical and which specialist might be best suited to manage her prednisone treatment moving forward.
Recurring Mysterious Rash Every Year, All Tests Negative
Hello everyone! I'm an 18-year-old female, and I don't consume alcohol, smoke, or engage in any recreational drug use. Around the middle of January last year, I noticed a gradual appearance of a rash across my body that escalated into a severe illness after approximately a week and a half of its onset. Currently, I find myself in a similar situation, suggesting that this might be a yearly recurring issue. At the moment, the rash isn't itchy, although I've recently had a mild sore throat. Thankfully, I don't have any other signs of illness right now. Last year, when I was unwell, it was an incredibly challenging experience; I felt extremely weak, had a runny nose, persistent cough, sore throat, and even experienced moments of confusion due to fever. The rash did become itchy once I fell ill. During last year's episode, I sought medical advice and underwent several tests while dealing with the rash. All results came back negative, including tests for mononucleosis. The only positive result was for a common cold. Having received vaccinations for measles, mumps, and rubella during my childhood (despite having had those diseases), I'm fairly certain this isn't related to any of them, and I believe I tested negative for those as well last year. Any insights or advice would be greatly appreciated! Thank you from a financially struggling college student!
Concerns About Abdominal Distension
Hello, I'm a 25-year-old female, weighing approximately 51 kilograms and standing at 155 centimeters tall. I have established allergies to Prospan and certain vitamins, which I actively avoid in my diet. My daily caloric intake is around 2250 kcal, and I supplement my nutrition with B complex vitamins, omega-3 fatty acids, and vitamins C and D. I do not have any identified food allergies that I know of. I maintain a workout regimen that spans four days each week, followed by a day of rest. However, I’ve noticed a consistent issue where my lower abdomen noticeably swells after each meal. To me, it resembles the growth associated with early to mid-pregnancy, and it seems to occur only in that specific area. This situation is worrying me, and I would greatly appreciate any advice you might be able to provide. I am contemplating visiting a gastroenterologist soon, but I thought I’d ask for perspectives here as well, just in case. Thank you for any insights you can share.

Sore Throat and Tonsil Discomfort for Three Weeks
For the past two weeks, I have been experiencing significant pain in my tonsils. After consulting with urgent care, I underwent tests for both strep throat and mononucleosis, but the results were negative. The doctor advised me to be patient as the discomfort was expected to subside on its own. Unfortunately, my condition worsened, prompting me to return to urgent care three days later. During this visit, I was prescribed dexamethasone, a type of steroid, along with a ten-day course of amoxicillin. Remarkably, my symptoms began to diminish within hours. However, just three days later, I am starting to feel the throat and tonsil pain return. I am still on the amoxicillin regimen. What could be causing this resurgence of pain, and what steps should I take next?
