Red Bumps Detected Under Daughter's Armpit

7/1/2025, 5:30:30 PMMale25-34

Recently, I noticed my daughter has developed some hard, red bumps located just beneath her right armpit. Initially, I suspected they might be caused by sweat or perhaps some irritation from her bra. However, while a couple of these bumps are showing signs of a whitehead, they don't resemble typical pimples and are only present on one side of her body. Additionally, they seem to be expanding and hardening, resembling skin tags or moles. I'm unable to share an image, but she has approximately 12 to 15 of these bumps. Normally, I wouldn’t rush to the doctor for minor concerns, but this situation is making me somewhat uneasy. Does anyone have any insights?

It's understandable to feel concerned about the hard, red bumps under your daughter’s armpit, especially since they’re increasing in number and hardening. The main points to consider include potential causes such as irritation, skin conditions, or infections. It's good that you are observing these changes closely.

Explanation: The bumps you described could be due to several factors. Some common possibilities include:

  1. Folliculitis: An inflammation of the hair follicles, which can appear as red, itchy bumps and sometimes have a whitehead.
  2. Contact Dermatitis: This occurs from irritation or an allergic reaction to products like soaps, lotions, or even the fabric of clothing.
  3. Lymphadenopathy: Swelling of lymph nodes, which can sometimes be felt as hard lumps under the skin, especially if there is a nearby infection.
  4. Skin Tags or Warts: These can develop in various areas, but usually appear over time rather than suddenly.

Since you noted the bumps are only on one side and expanding, this warrants attention.

Next Steps:

  1. Monitor Symptoms: Keep an eye on the bumps for any changes such as increased size, pain, or if they start draining fluid.
  2. Avoid Irritants: Make sure to minimize any potential irritants. Change her soap and use mild, fragrance-free options to see if this helps.
  3. Warm Compresses: You can apply a warm compress to the area for about 10-15 minutes a few times a day, which may help reduce inflammation or discomfort.
  4. Record Observations: Write down any changes or new symptoms, noting when they occur and their appearance. This will be useful if you need to seek further advice.

If the bumps do not improve, continue to grow, or if your daughter experiences symptoms like pain or fever, it would be wise to consult a healthcare professional for proper assessment. Your instinct to monitor the situation is important—trust your feelings in seeking additional support if necessary.

Navigating Potential Rheumatological Conditions: Seeking Advice

At just 19, I'm facing significant health challenges that have raised concerns about a rheumatological condition, possibly Behçet’s disease. My symptoms include skin lesions reminiscent of those associated with Behçet’s, joint pain, oral ulcers, neurological issues like seizures, severe eye problems, gastrointestinal distress, persistent low-grade fevers, and overwhelming fatigue. Despite undergoing an ANA test that returned negative, four different specialists have suggested that Behçet’s might be a factor, yet a definitive diagnosis remains elusive. A key consideration is my laboratory results, particularly the consistently high levels of C-reactive protein (CRP), which stand out even when I’m not experiencing flare-ups; I recorded values of 47 mg/L two months prior and spiked to 59 mg/L recently. Additionally, I show mild elevations in leukocytes, lymphocytes, monocytes, and eosinophils, all of which have remained elevated for several months. It’s important to note that many of these symptoms presented long before any potential chronic infections, and based on my research, the symptomatology does not align with typical infection profiles. I’m increasingly concerned about this ongoing high CRP level — should I be alarmed? Is there a significant possibility that I may indeed have Behçet’s disease? Compounding my worries is the need to change rheumatologists due to adjustments in my health insurance. This transition might prolong my journey to a diagnosis. How can I effectively communicate my case to the new specialist to ensure my concerns are taken seriously, and avoid starting from scratch?

MRI Results for Knee Pain – What’s Next?

Knee MRI Findings for a 27-Year-Old Female, 5’1", 130 lbs Apologies if my English isn’t perfect, as it’s not my first language. I underwent an MRI on my knee due to persistent discomfort. I experience pain when seated, especially when crossing my legs, and occasionally have difficulty returning to a straight position. Prolonged sitting can make it hard to extend my knee back out comfortably. This issue has been ongoing for several years, and I don’t engage in any high-impact activities. **MRI Findings:** - Minimal joint effusion was observed. - No cysts detected in the popliteal area. - No significant changes noted in the bone marrow signals. - The articular surfaces appear normal with no visible cartilage lesions. - There are changes noted in the posterior horn of the medial meniscus, which do not extend to the articular surface, likely indicating degenerative or contusion-related alterations. - Other parts of the meniscus show no signal changes. - The lateral meniscus remains intact. - The cruciate and collateral ligaments are in good condition. - The extensor mechanism is normal, with no signal changes in the quadriceps or patellar tendons. - The patella is positioned appropriately within the femoral trochlea. - Hoffa's fat pad shows no abnormalities. - Mild signal changes noted at the proximal attachment of the medial gastrocnemius muscle, indicating entesopathy. - Other tendons and the major bursae in the knee are without significant issues. **Conclusion:** - The alteration in the posterior horn of the medial meniscus is likely a sign of degenerative or contusion changes, not extending to the joint surface. - Signs of enthesopathy at the proximal insertion of the medial gastrocnemius muscle have been noted. What steps should I take next? This MRI was requested by my rheumatologist.

Understanding Inflammation in Relation to MRI Scans

Greetings everyone, I’m a 36-year-old male scheduled to undergo an MRI on my right elbow this week. This procedure is necessary because a potential loose body may be causing complications. I've been dealing with this issue for approximately two decades, but the discomfort has intensified recently. Typically, my elbow feels fine during daily activities, but any physical effort—lifting weights, playing ping pong, or relocating furniture—leads to significant inflammation and a sensation of it being "locked" the next day. Interestingly, while I can manage the discomfort in the moment, after a mild workout I found myself unable to hold my 5-month-old son for three days. I have a query: Should I attempt to provoke the inflammation before the MRI? At present, I’m resting the joint and have regained full mobility, but I want the imaging results to be as clear as possible in identifying the underlying problems. My concern is whether inducing inflammation might result in a noisier MRI, obscuring the clarity of the findings. Unfortunately, I wasn’t able to discuss this with the elbow specialist during my visit to the orthopedic clinic. Instead, I spoke with the physician's assistant who arranged the MRI, and I’ve been referred to a scoping specialist post-scan. Consequently, I haven’t been able to get insights from my full medical team. I would greatly appreciate any guidance or experiences you can share. Thank you!

Numbness Between Toes: A Concern

I am a 41-year-old man, weighing 190 pounds and standing 6 feet 1 inch tall. For the past week, I've been experiencing intermittent numbness between my big toe and the second toe. This sensation isn’t constant; it comes and goes. Initially, I noticed it during a swim when I felt a quick stinging sensation that led me to suspect a bee sting. However, there’s been no visible discoloration, no injuries, and no swelling—just occasional numbness. It hasn’t changed significantly over the last week. Could this be related to a pinched nerve or something else?

Unusual Bruise-like Rash on My Leg

Yesterday, I noticed an odd mark on my leg that resembled a bite. It was leaking a strange fluid. Initially, I didn’t pay much attention to it, but now it has swollen significantly, creating what looks like a crater. I struggle to find the right words to describe it, but the center feels entirely dry and seems unremovable. The coloration is somewhat green, with faint black lines running through it, and it becomes very painful when I apply pressure or put weight on that leg. After doing some research, I’m worried this could be something serious, like cancer or possibly a spider bite. I would appreciate any advice on this matter, and I apologize if my description is unclear.
