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.

Concerns About Angular Cheilitis

I’m a 23-year-old woman with no history of smoking, and I’m seeking assistance regarding a health issue. Back in January, I experienced angular cheilitis three times, each episode involving a minor crack at the corner of my mouth that healed within a few days. Following the last occurrence, I became quite anxious due to saliva accumulation in that area. I found myself frequently brushing my finger along that spot. After a few days, I observed a small area forming that appeared white and had a rough texture. Eventually, I realized it was not just a coincidence, and I started taking action, but only after it became noticeably larger. To address it, I cleaned the area with a mix of alcohol and apple cider vinegar. I’m uncertain about what this issue could be, but I’ve recently begun using over-the-counter Clotrimazole cream while also keeping the area moisturized with either lanolin or petroleum jelly. Unfortunately, I haven’t noticed any improvement, and I’m concerned as it seems to be expanding. The patch continues to be rough and excessively dry. Although I can open my mouth wide without any cracks forming, I do feel tension in the skin, similar to having a bandage over that location. At times, I experience a burning sensation after thorough washing, and I’ve noticed tiny red spots appearing on the outer edges of the patch sporadically.

Unusual Heart Sensation

I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.

Experiencing Heart Palpitations Following Chest Impact

I'm a 17-year-old female who has struggled with tachycardia for several years, having been diagnosed with postural tachycardia syndrome (POTS) about five years ago, although I haven't pursued further testing because I haven't completely lost consciousness. Recently, over the past month or two, I've started to experience sensations of my heart skipping beats, accompanied by difficulty in breathing during these episodes. These occurrences have become significantly more frequent, even when I'm at rest. Five years ago, I underwent a Holter monitor test, which indicated primarily tachycardia with occasional premature ventricular contractions (PVCs), but nothing alarming was found. In early December, I was struck hard in the chest by an elbow while in a mosh pit, which resulted in some pain when taking deep breaths for a few days. My sternum became bruised and slightly swollen, and it remained tender to touch for about two weeks, but this discomfort was manageable. I still feel some soreness when stretching, although it’s not severe. Additionally, I have diagnoses of Crohn’s disease and hypermobile Ehlers-Danlos syndrome (HEDS), and I am currently on immunosuppressants. Given these circumstances, would it be advisable for me to seek medical evaluation, or could these symptoms be considered typical?
