Unexplained Rash and Unpleasant Smell in the Armpit
I've noticed an unusual rash developing in my armpit, particularly in the crease area. While it’s not itchy, there is some mild sensitivity when I touch it. What’s particularly concerning is that there's a peculiar smell emanating from the rash, distinct from my regular sweat; it's quite strong and unpleasant. This condition has persisted for approximately 3 to 4 days now. Recently, I applied a new type of spray deodorant, which I've never used before. Could this possibly indicate an allergic reaction, even though my other armpit seems to be unaffected? Additionally, I've been sweating more than normal lately due to the warmer weather—is it possible that this could indicate a yeast infection instead?

Based on your description, it sounds like you might be experiencing a skin reaction that could be related to the new deodorant you've been using, combined with increased sweating. The unusual rash and unpleasant smell can often indicate a minor irritation or an allergic response. Here’s a breakdown of what might be happening and what you can do next.
Explanation:
-
Possible Causes:
- Contact Dermatitis: This is a skin reaction to substances that irritate the skin or cause an allergic reaction. Since you've introduced a new deodorant, it could indeed be a contributing factor.
- Yeast Infection: Increased moisture from sweating can enhance the growth of yeast, leading to a rash and odor.
-
Symptoms: The presence of a rash that is mildly sensitive but not itchy aligns with both contact dermatitis and a yeast infection. The distinct smell you’re noticing may be due to the combination of sweat and irritated skin or yeast growth.
Next Steps:
-
Stop Using the New Deodorant: Discontinue the use of the new spray deodorant immediately to see if your symptoms improve.
-
Keep the Area Clean and Dry:
- Gently wash your armpits with mild soap and lukewarm water.
- Pat the area dry thoroughly, as moisture can worsen the rash.
-
Use an Over-the-Counter Cream:
- Consider applying a mild hydrocortisone cream to reduce any inflammation, or an antifungal cream if you suspect a yeast infection (these are often available without prescription).
-
Monitor Symptoms:
- Keep an eye on the rash for any changes. If it starts to get worse or you develop additional symptoms like itching, more severe pain, or a spreading rash, it will require further attention.
-
Avoid Irritants: Wear loose-fitting clothing to minimize friction and irritants that could worsen the rash.
Please keep in mind that while these steps are effective for common skin issues, if your symptoms do not improve within a few days or worsen, seeking a professional opinion would be advised. Let me know if you have any more questions!

Severe Itching in the Genital Area
At 38 years of age, standing at 5 feet 2 inches and weighing 155 pounds, I am currently on a course of antibiotics, specifically sulfameth/trimethoprim at a dose of 800 mg. Recently, I experienced significant discomfort that led me to suspect I might be dealing with a kidney stone, as I was enduring considerable pain in my side and faced difficulties while urinating. The situation was so distressing that I sought medical attention at an urgent care facility on a Sunday, where I submitted a urine sample for analysis. Fortunately, the results indicated there was no urinary tract infection (UTI). Given my marital situation—having been married for five years and engaged in sexual activity only with my wife—I find it highly unlikely that I have a sexually transmitted infection (STI). Fortunately, two days later, the painful urination subsided notably, but subsequently, I began to experience intense itching. The area at the rear of the head of my penis, along with part of the shaft, has become so itchy that I can hardly tolerate it. Attempting to scratch only exacerbates the discomfort. There are no visible signs such as red bumps, sores, or any unusual discharge. Everything appears normal without dry or flaky patches. Despite that, I am plagued by a persistent, irritating burning sensation that remains throughout the day. I am unsure about the next steps to take, as this situation is extremely unsettling and uncomfortable.
Could This Be a Fungal Infection?
I'm a 23-year-old weighing 240 pounds and have been taking Wellbutrin regularly. Approximately a week ago, I observed that my fingers and some areas around my wrists were developing a slight redness. There's no itching involved, and the discoloration seems to worsen when my skin is warm or damp, which leads me to suspect it might be a fungal issue. Additionally, I've been dealing with a persistent ringworm situation after rescuing a stray cat, so I wonder if my current symptoms are connected, although it doesn't quite resemble ringworm to me. Today, I began using clotrimazole cream in the hopes of resolving this issue, but I wanted to confirm whether this is the most appropriate approach to take.
Concerns About Medication Left in Heat
At 27 years old, standing 5’5" tall and weighing 150 pounds, I have no history of smoking. Recently, I was diagnosed with mastitis and received a prescription for Keflex. After taking my initial dose on the way home, I completely overlooked the fact that my medication had been left in the car under the scorching sun for several hours while I dealt with a fussy baby. Although I ended up taking my nighttime dosage, I'm now worried about the safety of the medication. Should I reach out to the pharmacy in the morning to inquire about obtaining a replacement?
Ongoing Struggles with Yeast Infections
Hello everyone, I’m a 21-year-old woman, approximately 5'3" and weighing 125 lbs. This whole ordeal began in 2023 after I was prescribed antibiotics to combat persistent tonsillitis. Since then, I’ve been caught in a relentless cycle of yeast infections one after the other. I’ve consulted countless doctors, yet they all suggest the same treatments without any real solutions. The discomfort is overwhelming; my vagina often feels off, and sexual intercourse has become quite painful. Additionally, I’ve noticed two large lumps at the top and bottom of my vaginal opening, which adds to my distress. I feel like I have exhausted all possible remedies: I’ve tried Diflucan, changed my underwear frequently, used boric acid, and even applied Monistat, but nothing seems to provide relief. It’s driving me to the brink of frustration; I long to relish my intimate life again without the constant worry about my vaginal health. I find myself becoming increasingly anxious, almost feeling as though I might contract a yeast infection from mere breathing. Despite undergoing numerous tests, the results have only confirmed the presence of yeast. I’m desperate for help and answers—any guidance would be greatly appreciated!
Is This Bite Worth a Doctor's Visit?
I’m an 18-year-old female, and about a week ago, I discovered some bites around my ankle that I believe might be from fleas, considering the current flea problem in my home. Oddly, most of them haven't itched, apart from one that seemed to appear as a cluster. I initially scratched at it instinctively in the middle of the night after being awakened, but I don’t think I targeted the exact bite at the time. Recently, this particular bite has escalated; it's become redder and increasingly itchy. I've had additional bites since then, but none are as concerning as this one. I’m uncertain whether I should consult a physician, as I'm unsure if this reaction is typical. My mother suspects it could potentially be a fungal infection, though I’ve noticed a puncture mark in the center, leading me to believe it’s still more likely to be from a bite. I haven't experienced any fever or other symptoms. I’ll upload some pictures for reference in the comments.
