Red Itchy Bumps on the Abdomen
Greetings, I'm a 26-year-old male without any ongoing medications or identified health issues. The weather lately has been extremely cold, plunging below freezing. During my shift, I was bundled up to fight off the chill, but I had to spend some time indoors, which led to some sweating. The following day, I noticed the appearance of raised red spots on my stomach, which began to itch on the second day. I suspect it might be a heat rash or a contact dermatitis response from my wool undershirt, as I had a rare opportunity to sweat for about thirty minutes. I'm reaching out to see if anyone with more expertise could help determine whether this is likely due to my clothing or if there could be a chance of a bacterial or viral infection instead?

It sounds like you're experiencing raised red bumps on your abdomen that are itchy, possibly related to your clothing and the recent weather changes. The symptoms you're describing could very well be a heat rash or contact dermatitis from sweating or irritation from the wool fabric. Let’s break it down and explore your next steps.
Explanation:
- Heat Rash (Miliaria): This is caused by blocked sweat glands, which can happen when you sweat, especially if you’re bundled up in warm clothing. It typically appears as small red bumps and can be itchy.
- Contact Dermatitis: This occurs when your skin reacts to an irritant, like wool, especially if you sweat while wearing it. This can also lead to redness and itching.
- Bacterial or Viral Infection: While infections can cause similar symptoms, they are often accompanied by other signs, such as fever, swelling, or discharge. Your description suggests that a rash related to clothing or heat is more likely.
Next Steps:
- Keep the Area Dry: Change out of any sweaty clothing promptly and wear loose, breathable fabrics to minimize irritation.
- Cool Compresses: Apply a cool, damp cloth to the affected area for relief from itching and to reduce inflammation.
- Avoid Scratching: Itching can worsen irritation, so try to avoid scratching the area.
- Topical Treatments: Over-the-counter hydrocortisone cream can help reduce itching and inflammation. Alternatively, antihistamines (like diphenhydramine) may provide relief from itching as well.
- Monitor Symptoms: If the rash does not improve within a few days, spreads widely, or if you develop other symptoms like fever, consider a more thorough evaluation.
By addressing the irritation and keeping your skin cool and dry, you should see improvement. If symptoms persist or worsen, it's important to reassess and consider other possible causes. Take care!

Seeking Answers: Ongoing Chest Pain
For the past 20 days, I've been experiencing persistent chest pain accompanied by difficulty breathing and extreme fatigue. Initially, I sought medical attention where I underwent an electrocardiogram and a CT scan of my chest. The results revealed inflammation in my Thymus gland, for which the physician prescribed an anti-inflammatory medication and tramadol to alleviate the pain. However, after four days, my condition deteriorated, prompting me to return to the emergency room where I was admitted. My blood pressure was alarmingly high. While tests on my heart and lungs appeared normal, there was a slight strain noted on my left ventricle, yet this was not cited as a source of my discomfort, and the inflamed Thymus was overlooked. Morphine was the only medication that provided relief from the pain. Upon discharge, doctors suggested a tentative diagnosis of dyspepsia, though there was still uncertainty surrounding my condition. A week later, my symptoms persisted, leading me to visit a different hospital where I was told that my issues might be related to anxiety. Surprisingly, my psychiatrist disagrees with this assessment. Prior to these complications, I was in good health and regularly took medication for depression. I feel lost and overwhelmed. Is it possible that my Thymus gland is the root cause of these issues? A little about me: I’m a 28-year-old woman, I struggle with being overweight, and I’ve never engaged in smoking or drinking alcohol. My medical history includes just one surgery for gallbladder removal. I appreciate any guidance you can offer regarding potential diagnoses or next steps I should consider. Thank you!
Odd Symptoms: What Should We Be Wary Of?
Hello, my housemate (28-year-old female) has been experiencing some unusual symptoms for the past month. - She suffers from pain that occurs precisely every 5-6 days, having endured this for three weeks now. - The discomfort begins in the center of her chest, radiating towards the right side and then upwards to her throat. - Additionally, both of her ears have been intensely itching. - She characterizes the pain as both piercing and dragging. Despite our efforts, we have been unable to identify any specific triggers since nothing in her routine changes when these episodes occur (they generally arise when she is at rest). There are no signs of heart palpitations or dizziness. However, the intensity of the pain is significant, and it lingers regardless of her attempts to alleviate it. She intends to see a physician but is hoping to gather some insight into her situation beforehand to ensure that her concerns are taken seriously.
What Could This Bump Be?
I'm a 19-year-old male who recently had a wart excised from the bottom of my foot.

Is it Safe to Open L-Methylfolate Capsules?
I’m a 25-year-old female weighing 180 pounds, and I’m currently prescribed a daily dose of 20mg of Lexapro. While I don’t use marijuana, I occasionally consume THC-infused edibles. The L-Methylfolate capsules I have contain 1,000 mcg of this active ingredient but do not specify whether they are designed for slow release or extended absorption. I intended to blend the contents with yogurt or another food. Due to my OCD, I've found it challenging to swallow pills lately, and I've taken to cutting those I can. I simply want to verify that opening the capsules won’t compromise their safety or effectiveness. I also apologize if this inquiry is out of place; the pharmacy-related subreddits haven't been responsive to similar questions.
Understanding Delayed Satiety: Seeking Insights from a Doctor
Greetings everyone! Throughout my life, I’ve embarked on numerous journeys to shed some pounds, achieving varying levels of success. Lately, I’ve noticed a peculiar pattern regarding my appetite: I tend to experience a sense of fullness several hours after consuming my meals, typically around three to four hours later. During meals, I find that I can consume large quantities of food without feeling satisfied. However, as time passes—usually during that 3- to 4-hour mark—I suddenly become aware of a strong sensation of fullness that can at times be quite uncomfortable. I’m curious, what might be the underlying cause for this delayed response? For context, I’m not currently taking any GLP-1 medications. Interestingly, I seem capable of eating significantly more than the average person without registering any feelings of fullness initially. It’s only after a substantial interval that I realize, "Wow, I’ve overeaten." Additionally, it’s worth mentioning that I struggle with severe constipation, and attempts to increase fiber intake have only aggravated the situation. Perhaps my digestive system operates at a slower pace? After undergoing an endoscopy, I’ve also been informed that I have a J-shaped stomach, which could be relevant to my experiences. Any insights or explanations would be greatly appreciated!
