Concerns About Swelling Under One Armpit: Is It a Cause for Alarm?
I’ve observed some swelling beneath one of my armpits and I’m uncertain about it. It is painful when pressed, but it is not warm to the touch, and I don’t notice any lumps or unusual formations. I haven’t experienced any illness lately—perhaps about a month ago. I spotted this swelling around four days back, and there has been no significant change in size since then. Should I be concerned? I could visit a doctor, possibly after the upcoming week, though navigating healthcare here is challenging due to the language difference, as I live in a country where English isn’t predominant. I will provide additional details in a comment later if needed.

Swelling under the armpit can be concerning, but there are various benign causes that could explain what you're experiencing. Since the swelling is painful when pressed, but not warm to the touch or associated with any other illness, it may be due to localized inflammation or an infection, such as a swollen lymph node, rather than a serious issue.
Explanation:
The armpit area contains lymph nodes and various tissues that can become swollen due to several factors, such as:
- Infection: A superficial skin infection or a small abscess can cause swelling.
- Lymphadenopathy: This is when lymph nodes swell, often in response to infections in the body.
- Trauma: Any minor injury, even if unnoticed, might lead to localized swelling.
- Allergies or Insect Bites: Sometimes, reactions in that area can lead to localized swelling.
Next Steps:
-
Monitor Symptoms: Keep an eye on the swelling over the next few days. Note any changes in size, pain level, or the appearance of any new symptoms (like fever, redness, or spreading pain).
-
Self-Care:
- Warm Compress: Applying a warm, damp cloth to the area can help alleviate discomfort and may promote healing if there is inflammation.
- Pain Relief: Over-the-counter pain medication (like ibuprofen or acetaminophen), if appropriate for you, can help reduce pain and swelling.
- Avoid Pressure: Try to avoid pressing on the area, as this may worsen the discomfort.
-
Language Assistance: If you find it necessary to visit a healthcare provider, consider bringing someone who speaks both languages to assist you in communicating your symptoms clearly.
-
Follow-Up: If the swelling persists beyond one week, increases in size, or new symptoms develop, it's essential to seek medical care promptly.
Rest assured that many causes of underarm swelling are benign, but a careful watch over the next few days will help guide your next steps. Please update with any new symptoms if they arise.

Seeking Help for Ongoing Health Issues
I am reaching out in desperation for assistance! I'm wondering if anyone else has encountered similar health concerns or could recommend medications or specialists I should consider consulting. I'm truly at a loss and need guidance. As a 23-year-old male vegetarian weighing around 48 kg and standing at 5’4”, I have struggled with being underweight since my childhood. This condition has left me feeling utterly drained and overwhelmed. I’m eager to make a change but feel lost regarding where to begin or which healthcare professional to consult. In my youth, I was diagnosed with asthma, which has significantly improved; however, I continue to deal with low immunity, as I frequently catch colds and coughs from minor exposure to cold environments. Additionally, I’ve noticed that for the past few years, my body temperature feels abnormally high compared to those around me. I experience heat more acutely than my peers. Previously, I was quite active and could walk 4–5 kilometers daily without difficulty. Nowadays, even a short walk of 1–2 kilometers or climbing a few flights of stairs leaves me out of breath and exhausted. Even on days of little physical exertion, I feel weak and lethargic, as though all my vitality has been drained. My appetite has always been low, despite my efforts to increase it. I struggle to consume what would be considered an average meal for someone my age. Just two chapatis or a small bowl of rice or lentils fills me up completely, and attempting to eat more causes discomfort. I often find it perplexing how others manage to eat such larger portions. Dining out has become a challenge for me since even half a plate feels overwhelmingly full. Being extremely slender has made it difficult to find clothing that fits well and has adversely impacted my confidence over the years. For around 15 years, I have hesitated to take photographs of myself. Social and professional circles often regard me as younger than I am, sometimes even as a child, which has contributed to my feelings of invisibility and insecurity. My sensitivity to heat has intensified over the last few years. In seemingly normal room temperatures, I start sweating profusely while those around me remain comfortable. During cold weather, even in temperatures as low as 8°C, I don’t wear warm clothing, as I sweat excessively and feel anxious about overheating. The discomfort can escalate to a point where I feel faint from the heat. In my workplace, where the air conditioning is set at a standard temperature, I find it challenging. I begin to sweat visibly, leaving my clothes damp and prompting coworkers to inquire about my wellbeing. I often feel breathless and anxious that I might collapse if I remain there too long. This makes it very difficult to stay at the office or use public transportation, as even air-conditioned buses can feel uncomfortably warm to me. Over the past year, my situation has deteriorated further. I can no longer tolerate hot or even mildly spiced home-cooked meals, which I used to enjoy without issues. Now, even mildly spiced foods lead to excessive sweating, reddening of my face, and an intense burning sensation in my mouth, akin to consuming overly spicy dishes. As a result, my food intake has diminished even more. I often face ridicule for my dietary limitations, and I’m growing weary of trying to explain my condition, especially when my own family doesn't fully grasp the depth of my struggles, which adds to my distress. I am sharing my story because I truly need help. I wish to identify the underlying issues with my health and seek proper medical attention. If anyone has experienced similar problems or can recommend a suitable type of medical professional to consult, I would greatly appreciate your guidance and support during this challenging time. Thank you. 😭
Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.
