Rash Underarms
F33, based in the U.S., BP2, without any other known health issues. I have been dealing with an armpit rash for several months, which has significantly deteriorated over the last few days. There haven't been any changes in my deodorant, skincare products, laundry detergent, or any other potential contributing factors during this period. I've experimented with several approaches: I went several weeks without shaving, spent five days without using deodorant, focused on keeping the area dry and well-ventilated, and applied Aquaphor as well as an antifungal cream—not simultaneously, of course—but unfortunately, none of these efforts has yielded substantial results. The rash initially appeared at the edges of both armpits, and now it has spread, showing redness throughout the armpit fold, along with a thin white layer in the central region. It's causing significant itchiness and discomfort, although I do not have a fever or any other signs of illness.

It sounds like you've been experiencing a distressing and persistent armpit rash for several months, which has now worsened. This can be frustrating, especially when common remedies haven't provided relief. The symptoms you're describing, along with the rash's appearance and itching, may suggest a few potential causes, such as contact dermatitis, a fungal infection, or intertrigo (a rash from skin rubbing together).
Main Points:
- Your armpit rash may be due to a dermatological condition like dermatitis or a fungal infection.
- Keeping the area dry and ventilated is essential, but further targeted treatment or adjustments may be necessary.
Explanation:
- Contact Dermatitis: This can occur due to irritation or an allergic reaction to substances in deodorants, soaps, or even some fabrics.
- Fungal Infection: The thin white layer you mentioned may indicate a yeast infection, which occurs in warm, moist areas of the skin.
- Intertrigo: This is inflammation caused by skin folds rubbing together, leading to irritation and potential infection.
Next Steps:
-
Keep the Area Dry: Continue to keep your armpits dry and avoid any tight clothing that may cause friction.
-
Try a Different Antifungal Cream: Since you've already used one, ensure you're using a product specifically designed for fungal infections, such as one containing clotrimazole or miconazole. Apply it as directed for at least 2 weeks.
-
Hydrocortisone Cream: If you do not have any fungal infection, a mild hydrocortisone cream can help reduce inflammation and itchiness. Use it sparingly for short periods.
-
Monitor for Changes: Keep an eye on the rash over the next week. If it does not improve or worsens, consider re-evaluating your self-care regimen.
-
Avoid Irritants: Steer clear of scented products, and consider switching to a fragrance-free deodorant or none at all while you address the rash.
If you notice any signs of infection (increased redness, swelling, or pus), or if symptoms persist beyond another week’s trial of these measures, further evaluation may be necessary. Please let me know if you need more assistance or specific product recommendations.

Understanding the Reality of End-Stage Pancreatic Cancer
Navigating the complexities of end-stage pancreatic cancer can be overwhelming, and I'm seeking clarity on what lies ahead. My mother, who is 59 years old and weighs about 115 pounds, received her diagnosis of terminal pancreatic cancer in October 2025. Unfortunately, she has largely rejected the option of chemotherapy and is consuming her pain relief medications—specifically oxycodone and morphine—at an alarming rate. While I’m not worried about the dosage, the severity of her pain has reached a level that is becoming unbearable. Despite this, she is adamant about avoiding any hospital treatment, even though that's where she would receive the most effective pain management. I’ve attempted multiple times to get her medical attention, calling both hospitals and emergency services. However, due to her refusal for assistance, they have also turned us down. It was explained to me that taking her against her will could be considered kidnapping. After consulting with various healthcare professionals, I have been informed that her time may be measured in days or weeks. There’s also a chance that she could slip into unconsciousness, leaving me deeply unsettled. I am already in a state of mourning, yet I am desperate to understand what to expect in the coming days. It is crucial for me to prepare myself—emotionally and mentally—so that I can help ensure her comfort in these final moments. Plans are underway to engage hospice care, but the uncertainty fills me with apprehension. This is my mother, and I want to alleviate my fear so I can provide her with the support she needs as she nears the end of her journey. I yearn to be present for her without being entirely consumed by grief before she passes away. Any guidance or insight you could provide would be invaluable. I'm at a loss for what steps to take next and truly desire to navigate this situation with as much grace and readiness as possible.
Concerns After Gallbladder Surgery (Three Weeks Post-Op) - Is It an Infection?
Profile: - Age: 35 - Gender: Female - Height: 5 feet 4 inches - Weight: 160 pounds - Ethnicity: Asian Duration of Symptoms: Last Three Weeks Location: United States Recent Medical History: Nearly three weeks have passed since my gallbladder removal surgery. Over the last few days, I've noticed a small amount of unclear fluid coming from the incision. I just observed what seems to be pus oozing from the surgical site. Although there is slight tenderness when I move or touch the area, it isn't painful. Thankfully, I haven’t experienced any fever or chills, and there’s no unpleasant odor emanating from the wound. Should I continue to clean it with soap and water, or is it necessary for me to visit the emergency room for further evaluation?
Injury to the Sciatic Nerve
At 25 years old and weighing 135 pounds, I am currently taking naproxen and Lyrica to manage my sciatic nerve injury. The pain in my right leg has made it incredibly difficult for me to remain upright. It’s been two weeks since I first sought treatment; I consulted a physician who advised medication and attended a physiotherapy session. Initially, I experienced some relief after the appointment, but unfortunately, the pain returned the following day—even the prescribed home exercises exacerbated my discomfort. Just yesterday, I attempted the cobra pose, along with the flossing technique, which only heightened my pain. I find it nearly impossible to stand for more than a few seconds before the discomfort becomes intolerable. Additionally, I have an appointment with an osteopath on Tuesday, but I can't shake off my worries— is it normal to still struggle with walking after two weeks? Although I am experiencing some numbness in my toes, I haven’t encountered any loss of bladder or bowel control, worsening numbness, or weakness in my legs, so I feel stable in that regard. Nonetheless, I fear the possibility of never fully recovering and being left with a lasting disability. The pain is overwhelming, adding to my anxiety about the future.
Concern Regarding Persistent Tongue Bump with White Coating
I am a 24-year-old male, standing at 190 cm tall and weighing 109 kg. For the past five weeks, I've experienced a peculiar issue on my tongue. Specifically, there's a noticeable bump on the right side near the tip, which I believe may have been developing over time, although I'm not entirely sure about that timeline. Recently, I've been troubled by an unusual sensation, including dryness, an odd taste, and a slight decrease in my sense of taste. Additionally, I've observed a white coating that is more pronounced on the aforementioned side of my tongue. The bump in question: - Does not cause any pain. - May have increased slightly in size over the weeks, though I'm uncertain. - Appears smooth with a pink surface, free of bleeding or ulceration. Given that this issue has persisted for over a month, I am feeling quite anxious and am concerned that it may indicate a serious problem. I have no significant medical history, but I confess that my dental hygiene has not been up to par, as I haven’t been brushing regularly. At this moment, I’m also under medication for H. pylori, known as Pylera, but this tongue concern predates my treatment. I am a non-smoker and am reaching out for any insights on this condition. Has anyone experienced something similar? Could this be a sign of irritation, infection, or something benign? I really appreciate any guidance you could provide. Thank you!
Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
