Seeking Advice on Persistent Rash in Armpit
I’m a 41-year-old male, standing at 5 feet 10 inches and weighing 165 pounds, without any known medical conditions or prescribed medications. My last annual check-up in June indicated everything was normal. Recently, I developed a rash around the edge of my left armpit. Due to excessive sweating caused by hyperhidrosis, I’ve been washing the area frequently and using absorbent powders like Zeabsorb. After a few days, I noticed some red spots appearing on the surface of my armpit. Notably, these spots have not caused any itching, neither currently nor at the onset. Some of the marks faded after I applied Sudocream overnight, but the two central spots began to merge and become increasingly irritated. I tried using Elidel cream once, but that exacerbated the issue within just 45 minutes. Subsequently, I applied hydrocortisone 1%, which yielded minimal results. Considering it might be a fungal issue, I initially began treatment with Lamisil starting Wednesday. However, I switched to Ciclopirox cream last night because Lamisil was excessively drying out the skin. Despite these efforts, I’m not observing any progress; what once resembled a ring has transformed into a patch of inflamed skin. I’m uncertain about the next steps I should take to address this issue.

It sounds like you’re dealing with a frustrating and uncomfortable skin issue in your armpit, and it’s understandable that you want relief. Based on your description, it seems the rash might be related to your hyperhidrosis and potentially a fungal or irritant dermatitis, especially since you’ve noted worsening with certain treatments.
Key Points:
- Rash Characteristics: Red spots and merging patches suggest an inflammatory process, possibly a fungal infection.
- Current Treatments: Your use of antifungal creams (Lamisil and Ciclopirox) indicates you suspect a fungal issue, but your skin is responding poorly, likely due to irritation or over-drying.
Explanation:
Your ongoing rash, especially with the symptoms you describe, can be aggravated by excessive moisture and skin friction in that area. While fungal infections are common, the lack of itching and recent changes could also indicate irritant dermatitis. Using potent treatments like hydrocortisone and antifungals without improvement might contribute to skin irritation rather than healing.
Next Steps:
-
Stop Irritating Treatments: Discontinue the use of Lamisil and Ciclopirox for now to allow your skin to recover from possible irritation.
-
Gentle Cleansing: Use a mild, unscented soap to cleanse the affected area without scrubbing. Pat dry gently with a towel instead of rubbing.
-
Moisturize Daily: Apply a hypoallergenic, fragrance-free moisturizer (like CeraVe or Aquaphor) to keep the skin hydrated. This can help improve skin barrier function without causing irritation.
-
Monitor Symptoms: Keep an eye on the rash and note any changes in size, color, or discomfort. If the rash grows or you develop new symptoms like itching or discharge, adjust your observation accordingly.
-
Keep the Area Dry: Continue to use absorbent powders, but ensure they are non-irritating. Look for those that are specifically formulated for sensitive skin.
-
Consult If No Improvement: If the rash doesn’t improve within a week or worsens, considering your ongoing concerns, it may be beneficial to have a more in-depth evaluation by a healthcare professional.
It's essential to be patient with skin conditions like these, as they can take time to resolve. Remember, caring for the skin gently and consistently often yields the best long-term results. Please let me know if you would like to explore any specific aspects further!

Wrist Rash Associated with Apple Watch?
I’m a 24-year-old woman, 5'7" tall, weighing approximately 9.5 stone, and I am Caucasian. I’ve been experiencing a rash on my wrist for the past three days. Up until now, I’ve had no health concerns and I’m not taking any medication. The rash first appeared on Friday morning and was quite itchy. Thankfully, the itching has subsided, and its condition has remained stable since its onset. Being someone with sensitive skin, I've dealt with similar rashes in the past due to various products like fabric softeners and lotions, so this situation isn’t completely unfamiliar to me. After examining similar cases, I found that others have reported comparable rashes after using their Apple Watches. I’ve been wearing my watch frequently and have noticed that I tend to sweat, which might be contributing to this issue. I suspect I haven’t cleaned the strap adequately or possibly used cleaning products that are a bit too harsh for my skin. Currently, the rash appears slightly elevated, resembling a typical allergic response. It has a yellowish tint but does not exhibit any pus.
Should I Be Worried About a Possible Concussion?
A 25-year-old woman, around 5 feet 8 inches tall and weighing 165 pounds, who is not currently on any medication or drugs, encountered an incident while hiking at a historical castle. While navigating through a low brick archway, she miscalculated her height and struck her head against the top. For a brief moment, she experienced a loss of vision. Following the impact, there was some tenderness in her head, coupled with dizziness and mild nausea which subsided quickly—possibly attributed to anxiety or dehydration. However, a more pressing concern has arisen: she is finding it increasingly difficult to maintain focus with her eyes, about 45 minutes post-incident, and even articulating this message is proving to be quite challenging. She is uncertain whether she should seek medical attention and if so, whom she should consult and when.
Concerns About an Epidermoid or Dermoid Cyst
I currently have what medical professionals believe to be an epidermoid or dermoid cyst located in my submandibular region, near the neck. Following a difficult experience with a fine needle aspiration (FNA), the cyst became infected, necessitating two drainage procedures and a five-day hospital stay for intravenous antibiotics. Since then, I have been shuffled between various specialists without a clear plan of action. The cyst does not react like a standard cyst typically would, leading them to refrain from immediate surgical intervention. Initially, I was examined by an Ear, Nose, and Throat (ENT) specialist, then referred to a plastic surgeon. Following this, I underwent an MRI, which revealed some dubious findings that might involve my salivary gland and there were signs of scarring. This has now led to yet another referral to a maxillofacial surgeon. A significant issue I face is the long wait times for each appointment due to the inefficiencies within the healthcare system. In the meantime, I am dealing with an opening in the cyst that remains unhealed. This has led to the formation of a fistula, which continually produces keratin, a situation that genuinely worries me, particularly because I also suffer from intermittent severe, pulsating pain. The opening measures approximately 2 mm, large enough for debris to enter, which means that water from showering easily gets into the cyst. After showering, I gently expel some of the accumulated water along with the softened keratin. Additionally, I apply rubbing alcohol to keep the area sterile. While the cyst appears mostly deflated at this point, I'm uncertain about the best course of action. On one side, physicians have advised against squeezing the cyst as it could drive bacteria deeper and promote further infection. On the flip side, it feels alarming to allow tap water, known to harbor bacteria, or keratin, which could nourish bacteria, to remain inside. For months, I’ve managed this routine without triggering a secondary infection, but I’m unsure if I’m truly safeguarding my health or merely risking it. I feel directionless—no one has provided a definitive diagnosis or coherent guidance, and surgery seems to be a distant prospect.
Concerns About Colon Cancer Following Unusual Blood Test Results
In July, I underwent blood examinations which revealed a Hemoglobin level of 12.70 and a Hematocrit level of 39.2. These results pointed to anemia, prompting my primary care physician to recommend a consultation with a gastroenterologist. He informed me that gastrointestinal problems, particularly bleeding, are among the leading causes of anemia in younger men. Given my family history—my mother was diagnosed with colon cancer in her 40s—I'm feeling quite anxious about my situation. Is there a reason for me to be concerned?
Seeking Your Recommendations for Medical Guidance
Hello everyone, I'm a 29-year-old female reaching out for your recommendations. I have an upcoming appointment on October 28th, but I would appreciate any perspective you might offer beforehand. As someone diagnosed with celiac disease, I strictly adhere to a gluten-free diet. I can guarantee this since I prepare all of my meals myself and ensure that every product I use is gluten-free, being extra vigilant about my choices. Lately, I've been struggling with symptoms of gastroparesis nearly around the clock for more than a month. The discomfort has become quite challenging to manage. In addition to this, I've been experiencing persistent joint pain, frequent headaches, and discomfort at the junction of my head and neck. I've noticed small bruises appearing on my legs, and I'm becoming increasingly prone to bruising just from light scratching, which seems to happen often. While I'm not looking for a specific diagnosis, I would appreciate suggestions on what type of medical professional I should consult next, aside from my gastroenterologist. For context, I reside in New York, USA, and I typically visit Northwell Doctors and hospitals.
