Lesions in the Armpit Area

8/9/2025, 10:10:21 AMMale25-34

I am a 47-year-old woman, standing at 5 feet 4 inches tall and weighing 205 pounds. I deal with several medical issues, including hypothyroidism, Hashimoto's disease, osteoarthritis, bone spurs in my cervical spine, adenomyosis, fibromyalgia, chronic fatigue syndrome, chronic pain, TMJ disorder, irritable bowel syndrome, and optic nerve disk drusen, which has not yet posed any problems for me. Recently, I noticed some lesions located on the backside of my armpits. Although I had been experiencing discomfort for some time, my vision issues require me to wear glasses, which hindered my ability to see properly while showering. Initially, I assumed the irritation was a reaction to shaving. However, during a recent change near a mirror, I spotted these lesions for the first time. What might these be? I appreciate your assistance in this matter.

It's understandable to be concerned about lesions, especially given your complex medical history. The lesions you noticed under your armpits could be due to a few common causes, such as:

  1. Folliculitis: This is an inflammation of hair follicles, often caused by bacteria or irritation from shaving.
  2. Seborrheic keratosis: These are non-cancerous growths that can occur due to aging or skin irritation.
  3. Eczema or contact dermatitis: These skin conditions can cause red, itchy patches due to irritation from soaps, deodorants, or shaving.
  4. Heat rash: Especially in warmer weather, clogged sweat glands can lead to small, red bumps.

Given your situation, it's important to evaluate these lesions carefully.

Next Steps:

  1. Observe and Document: Keep an eye on the lesions for any changes in size, color, or symptoms (such as increased redness, pain, or discharge). Take note of any factors that seem to worsen or improve them.

  2. Gently Clean the Area: Wash the area gently with mild soap and water daily, and avoid harsh products. If you shave, consider pausing or using an electric razor to minimize irritation.

  3. Moisturize: Apply a gentle, fragrance-free moisturizer to keep the skin hydrated, which may help reduce irritation.

  4. Avoid Irritants: Pay attention to deodorants or skin products that may be aggravating the area. Opt for hypoallergenic products if needed.

  5. Control Other Factors: Stay hydrated and consider wearing looser clothing to minimize friction and sweating.

Keep monitoring these lesions. If they don't improve within a week or two, or if they worsen, consider reaching out to a healthcare professional for a more in-depth evaluation. They can provide tailored advice and treatment based on an examination. Remember, being proactive is beneficial for your health! Let me know if you need more specific guidance.

24M | Unexplained Fainting Incident

**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?

Healing Progress Post-GBS: Toe Concerns

I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.

Swelling Beneath My Chin Near the Jawline

18-Year-Old Male: I'm reaching out to any medical professionals who might provide insights into my situation. I've been using marijuana since I was 14, but now, at 17, I'm making an effort to stop and have been clean for 18 days. Recently, I've discovered an unusual swelling located just beneath my chin, behind my jaw. It causes some discomfort when I move, yet it doesn’t feel painful continuously. I'm somewhat anxious that this could be indicative of a more serious issue, especially considering it's positioned near my chin's lymph nodes. Any advice or information would be greatly appreciated as it might help alleviate my worry.

Challenges with Appetite and Discomfort While Eating — Difficulty in Gaining Weight

As an 18-year-old male, I find that I become satisfied after consuming rather minimal amounts of food. This situation presents a considerable challenge, particularly since I only need to have a standard breakfast, lunch, or dinner to feel completely satiated for the remainder of the day. My goal of increasing my weight has made this issue even more complicated. When I limit myself to one meal per day, I often face weight loss or an uncomfortable sensation of fullness that leaves me feeling sluggish. Opting for two meals makes me feel excessively bloated, distracting me from my daily responsibilities. Moreover, I suffer from an unusual issue with my throat, where almost any food I consume causes discomfort, as detailed in the list below. I have contemplated focusing on having just lunch while continuing my weightlifting regimen to maintain my current weight and gradually build muscle. What advice could you offer? Could there be an underlying cause for these symptoms? Lastly, would it be wise for me to consult a healthcare professional? Foods That Cause Discomfort: Bread, flour, pizza, fruits, sugary or starchy items, seed oils, chips, and essentially everything else. Foods That Are Tolerable: Rice, salads, chicken, fish, and vegetables. Overall Symptoms Include: * Quick satiety after normal meals * Challenges in gaining weight * Bloated and lethargic sensations when consuming more than one meal * Persistent throat sensitivity to a wide variety of foods
