Is This a Sign of Something More Serious?
Recently, I (30M) underwent treatment for what was thought to be a spider bite on my lower left leg. Fortunately, the symptoms weren't severe, but I did experience some infection along with headaches and fever. On Friday (March 14), I received an intravenous dose of antibiotics, followed by a second administration 24 hours later on Saturday. The following day, I was prescribed Cephalexin 500mg, instructed to take one tablet four times daily until the course was complete. Shortly after the first dose, I encountered severe diarrhea, the kind that disrupts your sleep and requires lengthy trips to the bathroom. In my quest to understand whether this reaction was typical, I stumbled upon information regarding C. difficile infections, which has left me feeling anxious about the possibility. I’ve noticed some blood in my stool and am uncertain whether this is due to the frequent bathroom visits or something more concerning. Initially, the blood appeared as bright red streaks on the toilet paper, but now it manifests as spots within the stool itself. Additionally, the stools are extremely watery and yellow. I’m not entirely sure if there’s mucus present, since I'm unfamiliar with the characteristics, but based on my findings, it might be possible.

It sounds like you've been through a lot with your leg infection and subsequent treatment, and your current symptoms are understandably concerning. To summarize, you're experiencing significant diarrhea and blood in your stools after starting antibiotics, which raises questions about your health.
Explanation
Diarrhea, particularly after antibiotic treatment, can occur due to changes in your gut bacteria, which can sometimes lead to infections, including Clostridioides difficile (C. diff). The blood you've noticed in your stool, especially if it has changed from bright red streaks to spots mixed within watery stools, is a concern and should be taken seriously. It may indicate irritation in the intestinal lining or an infection, among other issues.
Next Steps
-
Monitor Symptoms: Keep track of your diarrhea and any changes in the color or consistency of your stool. Pay attention to any increasing severity in pain or additional symptoms like fever.
-
Stay Hydrated: Diarrhea can lead to dehydration, so it’s essential to drink plenty of fluids. Consider rehydration solutions or electrolyte drinks to maintain your hydration levels.
-
Stop the Antibiotics: If you suspect that Cephalexin is causing these side effects, discontinue it but do this cautiously. It’s important that you speak to a healthcare provider when possible to discuss your symptoms and the best way to proceed.
-
Seek Further Evaluation: Due to the presence of blood in your stool and severe diarrhea, it's important to get a medical evaluation as soon as you can. This could involve a stool test to rule out infections like C. difficile or other causes.
-
Consider a Symptom Diary: Keeping a detailed log of your bowel movements, any additional symptoms, and your fluid intake can be very helpful for healthcare professionals when assessing your situation.
Your health is paramount, and while some gastrointestinal side effects can be common after antibiotic use, the presence of blood and substantial discomfort warrants attention. Please take care, and let me know if you have more questions or need further guidance.

Rash on the Dorsal Side of My Hands
A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?
Understanding Foam in Urine: When is it a Concern?
Age 24, I've observed a notable increase in the amount of foam in my urine over the past couple of years, compared to what I remember from before. About a year ago, I mentioned this to my primary care physician, who seemed somewhat dismissive of my concerns. Nonetheless, they proceeded to conduct a urinalysis, which returned normal results, indicating no elevated protein levels. I frequently undergo blood tests, and both my eGFR and creatinine levels typically fall within the normal range, although I did experience some fluctuations linked to a bout of mononucleosis a couple of years back, where my eGFR dipped near 70; it currently remains above 100. I suspect that changes in my urological function, likely from aging, are contributing to a stronger urine stream now than in my youth. The foam generally settles down after a few minutes, although occasionally it lingers longer than expected. I make a concerted effort to stay hydrated, even though I don’t always succeed, so I wonder if mild dehydration could partially account for the foaming. This concern is particularly relevant as I'm resuming strength training and planning to increase my protein consumption. I want to ensure that my kidneys are not overtaxed due to any potential underlying issues. Additionally, I have a history of taking 5 grams of creatine daily, paired with plenty of water, which makes me cautious about this, too. Is there a point at which foaming in urine is considered excessive, or does a specific threshold exist that I should be aware of?
Understanding Symptoms of Salmonella: What to Do Next
My boyfriend, who is 26, experienced a fever that peaked at approximately 99.5°F yesterday morning. Thankfully, after resting and taking NyQuil, his fever subsided by this morning. However, he has been dealing with severe abdominal pain and persistent diarrhea since last evening, which has not shown much improvement. He has been making frequent trips to the restroom, nearly every hour throughout the night and again today. While I initially thought he might be improving since the fever has decreased, I became alarmed upon noticing bright red blood in his stool and on the toilet paper after he wipes. It has been around 40 hours since the fever began, and my concern has heightened now that blood has appeared. I’ve come across some online information suggesting these symptoms might be typical for salmonella infections, and I’m uncertain whether we should seek medical attention immediately or if it’s advisable to wait another day or two to see if his condition improves. I realize that consulting a doctor as soon as possible would be the best course of action. However, he currently lacks insurance, which makes him hesitant to get checked right away. Any guidance on this matter would be greatly appreciated, thank you.
Navigating Alcohol Challenges
My partner has recently developed issues with alcohol. Over the past year, he has been consuming significant amounts—roughly two bottles of distilled spirits each week, in addition to beer. A decade ago, he struggled with inhalants and even faced near-fatal consequences, but he had maintained sobriety until he turned to drinking. He believes he has plenty of time before the effects of alcohol will manifest. How long can he continue this way before it becomes a serious problem? He is a 53-year-old male, weighing 325 pounds, standing at 5 feet 11 inches, and he is currently on medication for hypertension. Although we plan to separate later this year, it’s clear that this situation will have an impact on our three children.
Persisting Chills Without Fever for Three Weeks After a Cold
Greetings! I'm a 30-year-old male dealing with a rather unusual situation, and I'm at a loss for what to do next. As mentioned in the title, I recently experienced a cold, which presented all the expected symptoms, but the chills have lingered. It's been around three weeks now, and I still feel cold despite wearing multiple layers and having the heater running in my home. Strangely, throughout this episode, I haven't had a single fever. I consulted my primary care physician, who also seemed puzzled by my symptoms. She has requested some blood tests which are scheduled for Monday, even though I had blood work done three months ago that showed normal results. Does anyone have insights into what might be causing this? I understand there could be various explanations, but I'm unsure how to proceed. I am not currently on any medications and don't have any known chronic health conditions. Any guidance on how to tackle this issue would be greatly appreciated! 🙏
