Seeking Guidance for Underarm Rash
I'm looking for some guidance regarding my boyfriend's health issue. He is a 27-year-old male, standing at 6 feet 3 inches tall and weighing 230 pounds. He isn't taking any medications apart from a daily vitamin and is a nicotine vaper. While he hasn't had any major health concerns in the past, he may be dealing with carpal tunnel syndrome due to his job-related activities. Recently, he developed a rash in his underarm that initially appeared mild—just some redness without bumps. However, in the past week, the condition has worsened considerably. He is quite stubborn and resistant to visiting a physician. He has chosen to stop using deodorant on that side without any noticeable improvement. We've also tried applying Lotrimin, but it seems ineffective. Any advice would be appreciated!

It sounds like your boyfriend is experiencing a troubling skin issue with his underarm rash that has worsened despite his attempts to treat it. Given the situation, here are some key points to consider, an explanation of possible causes, and prioritized steps you can take to help manage this condition.
Main Points:
- The rash could be caused by a variety of factors such as friction, irritants, fungal infections, or dermatitis.
- Immediate steps should include monitoring the rash closely and applying soothing treatments.
- If there is no improvement, or if the rash worsens, a more proactive medical approach may be necessary.
Explanation:
The rash in his underarm might result from several common issues:
- Irritant Contact Dermatitis: This can occur due to substances in deodorants or sweat.
- Fungal Infections: These can manifest as redness and irritation and can spread if untreated.
- Heat Rash: This often happens in warm, moist areas and can appear similar to the rash described.
Since he stopped using deodorant and applied Lotrimin without relief, it’s essential to reconsider the approach.
Next Steps:
-
Keep the Area Clean and Dry: Gently wash the area with mild soap and water. Pat it dry thoroughly to prevent moisture build-up, which can worsen rashes.
-
Apply a Barrier Ointment: Use an over-the-counter hydrocortisone cream (1%) to reduce inflammation if irritation is significant. Use it in small amounts for a brief period (no more than a week).
-
Reassess Moisture Control: Consider using a corn starch or talc-free powder after bathing to help absorb moisture, which may prevent further irritation.
-
Monitor the Rash: Keep a close eye on any changes—the rash should start improving with proper care within a few days. Document any changes to its color, texture, or size.
-
Avoid Irritating Activities: Encourage him to wear loose-fitting clothing, especially if he has an active lifestyle, to reduce friction and irritation.
-
Consider Allergy Testing: If the rash persists, he might want to explore potential allergies to certain materials (clothing, soaps) with the help of a healthcare provider.
If the rash does not improve in a week or worsens with new symptoms, encourage him to seek professional medical advice as further examination may be necessary to diagnose and treat the issue effectively. Being supportive and understanding during this process can help alleviate any concerns he may have about visiting a doctor.

Understanding and Addressing Persistent Yeast Infections
Greetings everyone, I’ve been struggling with recurring yeast infections for quite some time, but lately, the situation has escalated significantly. As a 25-year-old female, I’ve developed dry patches on my vulva. These areas tend to scab over, and when I refrain from touching them, they occasionally become irritated and itchy. This leads me to scratch, which sometimes results in bleeding. On one occasion, while pulling at a scab, I noticed a long white strand emerge—similar to what one might see when a pimple is popped, where the skin pulls away. This was followed by the area bleeding from the follicle. I’ve tried over-the-counter yeast infection treatments, which provide temporary relief for a few weeks before the symptoms return. I maintain a consistent hygiene routine, showering regularly, and I use only unscented soap for cleansing. I would greatly appreciate any insights or advice on how to manage or alleviate this condition. Thank you!
Need Guidance on a Rash
At 19 years old, I've developed a rash underneath my chin that is quite painful. It hurts whenever I move my chin or even touch that area. I only just noticed this mark and I'm unsure whether I should be worried about it or if it could simply be a bruise. Honestly, I'm puzzled about how I might have gotten a bruise there without realizing it. Can anyone provide advice or insight on what this could be?
Understanding Persistent Sore Throats: Seeking Answers
Greetings everyone, I’m a 42-year-old male who has struggled with severe sore throats accompanied by fever on an annual basis for as long as I can remember. While these episodes don’t occur at the same time each year, they are indeed a consistent occurrence. In my childhood, these infections were typically strep throat, which would respond well to antibiotics. However, during periods without insurance, I had to endure the discomfort without treatment. Currently, I have health coverage. My initial visit to a doctor for this issue revealed what she described as an exemplary case of strep, prompting her to prescribe penicillin, which led to my recovery. Interestingly, despite the test results indicating negative for strep, she trusted her clinical impressions and advised me to complete the antibiotic course. On another occasion, when I sought medical help as soon as symptoms emerged, the physician suggested it was likely viral. After conducting a rapid test with a negative result, she advised me to manage the symptoms on my own. A subsequent visit confirmed a positive strep test, and I was successfully treated again with penicillin. Most recently, I consulted my doctor immediately after feeling unwell; she suspected it might be viral again and performed a test, the results of which I will receive shortly. In addition, my fevers tend to be quite severe, reaching highs of up to 104°F, though Tylenol helps reduce it to around 102°F. Typically, I will have about two days at 102°F before escalating to 104°F for a span of two days, followed by another three to four days at around 101°F to 102°F. This pattern can change if I am prescribed antibiotics. Notably, throughout these episodes, I have never transmitted the illness to anyone, including my two past partners and my young son; none seem to contract it from me. Is this simply a recurring issue that I must endure, or is there further investigation I should request from my doctor? I would greatly appreciate any guidance or insights you might have!
Encounter with a Raccoon
A 26-year-old male, measuring 5'9" and weighing 180 pounds, currently not on any medications, shares his experience. Residing on a college campus that features a small lake, he recounted a happening from last night while comfortably seated by the water, engrossed in a book. To his surprise, two raccoons approached him. In a moment of curiosity, he extended his hand, which resulted in one raccoon giving him a light nip; fortunately, it wasn’t puncturing enough to harm his skin. Soon after, the raccoon moved on to bite his shoe. When he illuminated them with his flashlight, they swiftly scurried up a nearby tree. He has since noticed a tiny red spot on his finger where the raccoon made contact, which was mildly itchy for a while. He is now concerned whether this situation poses a risk for rabies exposure.
What Could Be Causing Discomfort and Tightness in My Left Index Finger?
At 34 years old, standing at 189 cm and weighing 91 kg, I find myself concerned about a recurring discomfort in my left index finger. The pain presents as an aching and throbbing sensation, particularly noticeable during flexing or while the finger is at rest. Overall, my health is stable; I have no notable medical history to report, and I don’t take any medications. I maintain a clean lifestyle, refraining from alcohol, tobacco, or recreational drugs. I currently reside outside of the United States. The issue arises specifically at the distal phalanx joint of my left index finger. Upon flexing, I experience a tight sensation. I can completely contract the finger, and when compared to my right index finger, there appears to be no difference in its position or angle. There is no visible discoloration to indicate an injury, such as bruising or frostbite. Interestingly, my right index finger has a slightly reddish appearance and feels warmer to the touch—currently, it’s 2 degrees Celsius warmer than the left finger. At times, I notice a mild throbbing sensation and slight pain at the joint of the left finger, especially noticeable during the morning when I’m still in bed. This discomfort commenced approximately a month ago while I was removing a car battery from my vehicle, which was parked in a frigid garage just a short distance away. The temperature outside was extremely low, around -16°C (3.2°F), and windy. Although I was only outdoors for about half an hour, I found it necessary to remove my winter gloves for a brief moment. Ironically, I had brought along a new pair of gloves intended for assembly work, which I later wore. Unfortunately, despite their decent quality, they were only lightly insulated and not suitable for such cold conditions—a lesson I learned the hard way. Shortly after completing the battery removal, I began to feel discomfort in my left index finger when I tried to flex it, even fourteen hours later, when I was back indoors and had warmed up. Curiously, there were no clear signs of frostbite; I simply had cold hands. Could the sensation be related to blood vessels, nerves, or something else entirely? Is it possible for veins to sustain damage from extreme cold, even with brief exposure times? I have recollections of experiencing similar symptoms in this very finger around eight years ago, which eventually subsided without intervention. While I suspect this could resolve again on its own, it does make me ponder why this issue happens exclusively to my left index finger and always at the same location.
