Unexplained Rash on Left Arm for the Past Week
Hello! I would really appreciate any information regarding the unusual condition affecting my arm. I’m a 27-year-old woman, standing 5'9" and weighing 240 lbs. I vape regularly, but I don't take any medications currently. The last time I was on medication was two years ago when I was prescribed antibiotics. I consume alcohol moderately and have no current medical diagnosis. Additionally, I had my gallbladder removed in August 2024. About a week ago, I noticed a peculiar rash or hives solely on my left arm. The appearance of the bumps varies; they are generally small and red but sometimes appear white. Their forms shift, with some showing as patches and others appearing long and horizontal. While the area itches, it isn't enough to compel me to scratch or apply immediate relief. Initially suspecting an allergy, I began washing my hands and arm after each activity, yet the condition persists. This occurrence began last week around 6 PM while I was at work. I wear long sleeves as part of my uniform, and there have been no alterations to it. My daily schedule remains unchanged—a morning shower, feeding the animals (including chickens, emus, and a cow), and going to my job. There haven’t been any new foods, beverages, or soaps introduced into my life. My routine has been quite consistent and predictable for many years. The rash is limited to my left arm and exhibits a fluctuating pattern; it appears to diminish and expand during the day, disappearing for short times before returning. There’s no significant swelling or pain, just a series of slightly itchy, red, raised bumps that are asymmetrical in appearance.

A rash on your arm that has been present for a week, especially one that is itchy and exhibits changes in appearance, can be concerning. While many skin rashes are benign, they can also be caused by allergies, irritations, or other underlying conditions. Let’s address your situation clearly and compassionately.
Main Points:
- Possible Causes of Rash: The changes and symptoms suggest that it could be an allergic reaction, an insect bite, or a form of dermatitis.
- Recommendations: Monitor symptoms, determine triggers, and consider self-care options.
Explanation:
Given that you have not introduced any new foods, soaps, or routines, and considering the rash is only on one arm, it may be a contact irritant or an allergic reaction to something you come into contact with during your daily activities. With your routine involving animal care, the rash may also be a reaction to hay, animal dander, or even insect bites.
Next Steps:
-
Monitor and Record: Keep a diary of your symptoms. Note any activities you are doing when the rash appears or worsens. Look for patterns that might help identify a trigger, such as specific animals you handle or after specific tasks.
-
Minimize Irritants: While you are already washing your hands and arms frequently, consider wearing gloves when feeding or interacting with animals to reduce direct contact with potential allergens or irritants.
-
Apply Soothing Treatments: Over-the-counter hydrocortisone cream may help alleviate itching and redness. Antihistamines (like diphenhydramine or loratadine) can also provide relief from itching but consult with a pharmacist if you’re unsure.
-
Avoid Known Irritants: If you've been doing any tasks that might expose your skin to potential irritants (such as tars, chemicals, or rough materials), try to avoid those for the time being.
-
Observe for Changes: If the rash begins to swell, spread, or cause severe discomfort, or if you experience other symptoms like fever or difficulty breathing, these would be reasons to seek further evaluation from a healthcare professional.
Keep a close eye on the situation and don't hesitate to reach out if symptoms worsen or change in an alarming way. You're taking a proactive approach, which is essential! Let me know if you need further guidance or have any other questions.

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.
Developing an Itchy Rash Following a Client Visit
A 44-year-old woman, without any significant health issues apart from allergies and not currently taking any medications, encountered an uncomfortable situation after a client visit. While working in social services, she noticed an itchy rash that appeared shortly after leaving the client’s residence. Although she initially suspected a bed bug infestation, no evidence of these pests has been found since her departure. Upon returning home, she took certain precautions but now finds herself uncertain about the source of the rash. She visited multiple clients the previous day, making it difficult to pinpoint when the irritation began. The rash became noticeable yesterday and is indeed bothersome. Currently, she has observed the rash on her back, as well as on her lower thigh, and has noted a few spots on her arm and leg. The situation remains concerning as she seeks to identify the cause of this unexpected skin reaction.
Managing Allergic Reactions to Bactrim: Should I Wait It Out?
I'm a 31-year-old female residing in the USA. I’ve been experiencing symptoms such as discomfort during urination and pain on one side of my back. After seeking attention at an urgent care center, the medical professionals suspected I might have a urinary tract infection or a kidney infection, with lab results still pending. They prescribed me Bactrim, instructing me to take it twice daily over the course of 14 days. Having taken my first dose roughly an hour ago, I’m now experiencing itching (without any hives) along with some redness and warmth in my face. My breathing feels normal, and I don’t have any additional concerns at this moment. Is it advisable for me to simply pause the medication until I can consult with my doctor tomorrow?
