Finding a Lump in My Right Armpit
For the past five weeks, I've noticed a small lump, approximately the size of a grain of rice (0.5 cm), in my right armpit. After visiting my general practitioner, they suggested it might be due to an ingrown hair or possibly an infection. I was prescribed antibiotics, but there has been no improvement; the lump persists, although it may have slightly reduced in size recently. From the onset, I’ve experienced persistent pain and discomfort. **What could be the underlying cause? What actions should I consider taking next?** Aside from this issue, I do not have any additional symptoms. I continue with my regular jogging routine, and I don't experience night sweats or any other health concerns. However, I find myself sweating more from my armpits due to my preoccupation with this lump. I am a man in my 30s.

It's understandable to feel concerned about a persistent lump in your armpit, especially given the discomfort and your efforts to treat it. Since the lump has not improved significantly despite antibiotic treatment, there are a few possibilities to consider, such as an inflamed lymph node, a cyst, or another benign growth. However, the absence of additional symptoms is reassuring.
Explanation:
Lumps in the armpit can arise from various causes:
- Ingrown hairs: These might cause lumps filled with pus (abscesses), which can resolve with treatment.
- Lymph nodes: They can become swollen due to infections in the area or other benign causes.
- Cysts: These are fluid-filled sacs that can also develop in this region and might not disappear easily.
Persistent pain and discomfort in the area further suggest that follow-up is prudent, especially since your symptoms haven't resolved with initial treatment.
Next Steps:
-
Monitor the lump: Observe any changes in size, shape, or associated symptoms (e.g., redness, warmth, or new lumps nearby). Keeping a simple diary can help track these changes.
-
Apply warm compresses: Gently applying a warm compress to the area may help reduce pain and encourage any possible fluid to drain if it is a cyst or localized infection.
-
Consider a follow-up with your doctor: Since the original antibiotic treatment hasn't resulted in improvement, it may be beneficial to discuss the need for further evaluation. This could include imaging (like an ultrasound) or a more thorough examination to rule out other causes.
-
Manage discomfort: You can take over-the-counter pain relievers (like ibuprofen or acetaminophen) as needed for pain management, unless advised otherwise by your healthcare provider.
-
Stress management: Since you're feeling anxious about the lump, engaging in stress reduction techniques (such as mindfulness, breathing exercises, or light physical activity) can help ease your preoccupation and potentially lessen sweating.
Your health and well-being are paramount, so advocating for further evaluation with your healthcare provider is important if you have ongoing concerns. Let me know if you have any more questions or need further guidance!

Seeking Guidance on Bowel Movement Challenges for My Disabled Brother
I am reaching out for advice regarding my brother, who is 30 years old and resides in a care facility for individuals with disabilities. While my separated parents share custody and make medical choices for him, it is likely that I will eventually take on that responsibility. My brother has been diagnosed with autism, yet the situation is more complex. His cognitive abilities and conversational skills resemble those of a young child, making it difficult for him to communicate or understand his own needs reliably. The crux of the issue is that over the past two years, he has been experiencing significant difficulties with bowel control. His underwear often ends up soiled, and in unfortunate circumstances, so do his pants. When we are in public, it becomes apparent that he frequently requires access to a restroom. He has consulted with a medical professional and undergone tests for gluten and lactose sensitivities, which came back negative. There seems to be a consensus that he does not purposely soil himself, and I sometimes doubt that he is even aware that there is a problem. If he realized he was doing something inappropriate, it would likely cause him distress. Additionally, his personal hygiene habits are quite mechanical—he approaches wiping as he does brushing his teeth or washing his face, relying on instinct rather than genuine understanding. We cannot continue on this path; it is crucial to investigate the underlying issues. The current state is affecting his overall well-being. I am at a loss for how to proceed, so I would greatly appreciate any suggestions or insights you might have.
Increasing Swelling from RT Conjunctivitis: Need Advice on What to Do Next
About two weeks ago, on February 19, I noticed a clear liquid leaking from one of my eyes, which quickly led to swelling within a few hours. After consulting a doctor, I was prescribed eye drops that resulted in significant improvement over the next few days. However, I stopped using them afterward. Fast forward to about five days ago, I developed a severe cough alongside a cold that has been recurring since early February. That same day, the previously affected eye began to produce a whitish discharge. I sought medical attention for the cough and received a week’s worth of medication, with advice for further tests if my condition didn't improve. The prescribed medications included: - **Doxophylline 200 mg** - **Azithromycin Dihydrate** - **Montelukast Sodium** The following day, the whitish discharge shifted to a clear one. My eyes became red, but the swelling was somewhat bearable. Fortunately, I didn’t experience much pain or blurry vision—though my eyelids occasionally felt sticky, and the redness continued to be an issue. Despite using two prescribed eye drops for four days, I didn’t see any improvement: - **Moxifloxacin Hydrochloride** (0.5% solution) - **Povidone Iodine** (5% sterile eye drops) Since last night, however, the swelling in my eyes has escalated dramatically, making it extremely difficult to keep them open, resembling the aftermath of a severe insect bite. I’m feeling uncertain about what steps to take next. Is this reaction typical considering my diagnosis of right conjunctivitis? Are my cough medications potentially influencing my eye condition? I’m looking for input or suggestions before I consider seeking a new doctor or waiting a few more days, as my symptoms worsen. I’ve already seen an eye specialist twice and have another appointment scheduled in two days. Additionally, because my pay is being reduced due to this extended medical leave, I am being cautious about any expenses related to changing doctors or treatments. This query comes from a friend, as I’m currently unable to use my phone effectively due to my health issues. On a side note, two family members developed conjunctivitis four days ago, but they seem to be recovering well.
A Regretful Mistake
Lately, I've been feeling mentally exhausted and longing for a break from school (I'm 18). In a moment of poor judgment, I came across a stir fry in the fridge that had clearly overstayed its welcome—three months old, and it only had three carrots left. One of them showed signs of spoilage with a dark spot. Honestly, it tasted really unpleasant. Now I'm left worrying about my health. I feel queasy right now, and I'm not sure if it's due to my anxiety or if it’s a reaction to what I just ate. It completely slipped my mind that botulism is a risk, and only after finishing the carrots did I remember that wasn’t the wisest decision. Logically, I'm guessing I’ll be okay since it was just a small quantity of food, but should I reach out to a healthcare professional for advice? I can only hope that the worst outcome is merely food poisoning.
Concerns About Persistent Throat Discomfort and Blood Coughing
**Personal Information** *Age:* 31 *Gender:* Male *Height:* 5'11" *Weight:* 206 lbs *Ethnicity:* Caucasian **Duration of Symptoms:** 2-3 weeks **Relevant Medical History:** None **Current Medications:** None For the past five years, I've experienced intermittent bouts of tonsil stones, which began during the COVID-19 pandemic. While these stones usually vary in their frequency and severity, I have recently encountered the unsettling feeling of having one lodged near my Adam's apple that has persisted for the last couple of weeks. Despite this, I hadn’t expelled any tonsil stones until this morning when, while showering, I coughed up a small amount of blood. This is an alarming first for me, and I verified that the blood did not originate from a nasal source. Should I be worried that this could indicate a more serious underlying health issue?
Assistance in Stroke Rehabilitation
Hello, everyone. My mother, an 81-year-old woman who stands at 5’6 and weighs 130 pounds, is currently in short-term rehabilitation following a stroke. She has lost the ability to use the left side of her body but is gradually recovering movement in her left hand. Remarkably, about a week after her stroke, I noticed her left leg beginning to move again, although this occurred while she was resting. Unfortunately, I haven't observed any leg movement since then, but she can still slightly move her toes due to pain. Her physical therapy sessions last around 10 minutes daily, five times a week. However, I’ve noticed that the diaper changes are quite distressing for her, especially since she has dementia and is often confused about her circumstances. My presence seems to help when I talk to her during these moments. Given my mother's advanced age and my concerns about her recovery, my ultimate objective is for her to regain the ability to walk. My dilemma is whether to keep her in the rehabilitation facility to let the professionals continue their efforts or to bring her home for outpatient rehabilitation. I would appreciate any advice, especially since time is critical for her recovery. ❤️🩹
