Persistent Painful Lump in Armpit — Ultrasound Diagnosis Indicated Tear but Discomfort Continues
Age/Sex: 27 Female Medical Background: Diagnosed with rheumatoid arthritis and early thyroid antibodies. Recent blood tests show normal results. I do not smoke and am currently making an effort to quit vaping. I maintain a healthy diet, exercise every day, and generally consider myself to be in good health. Symptoms & Timeline: - A few months prior, I discovered a painful lump located under my armpit. - The lump is mobile and its form varies; at times it appears round, while at other moments it takes on a longer or thicker appearance, or becomes oddly shaped. - Touching it, lowering my arm, or pressure from my bra intensifies the pain. - There are no visible signs of redness or infection. Medical Evaluations: - An ultrasound was conducted. - The physician’s assistant indicated a possible musculoskeletal tear and recommended taking Aleve or ibuprofen for relief while monitoring the situation. - I have followed this advice, but the discomfort persists. - The ultrasound results did not indicate any issues with lymph nodes or any worrisome conditions. Current Condition (Months Later): - The pain persists, and the lump remains unchanged. - It is still movable, occasionally feeling swollen, and its shape continues to alter. - This condition disrupts my daily activities and comfort. My Concerns/Questions: - How long is it typical for a musculoskeletal tear to produce this level of pain? - Does my description align with a musculoskeletal tear? - Should I seek additional imaging, such as an MRI, or consider obtaining a second opinion? Thank you for any insights or suggestions you can provide!

It sounds like you're dealing with a persistent and uncomfortable issue, and it's understandable to be seeking clarity and relief. Let's break this down:
Key Points:
- Persistent Pain: Musculoskeletal tears can vary in recovery time, but ongoing pain after several months can be concerning.
- Symptoms Monitoring: Your description suggests ongoing irritation, which is not uncommon for musculoskeletal issues, but it may also indicate the need for further evaluation.
- Next Steps: Consider monitoring your symptoms, exploring additional imaging, and possibly seeking a second opinion, especially if your current symptoms interfere significantly with daily life.
Explanation:
A musculoskeletal tear such as those affecting muscles or soft tissue can indeed cause chronic pain. The discomfort may persist for several weeks or even months, depending on the nature of the injury and your body's healing response. The fact that the lump is movable and varies in shape can align with a benign condition, but persistent pain warrants further investigation—in particular, since there are no signs of infection or worrisome imaging findings.
Actionable Steps:
-
Symptom Tracking: Keep a detailed log of your symptoms including pain intensity (on a scale from 1-10), any activities that worsen or alleviate the pain, and any new symptoms that arise. This can help identify patterns and provide crucial information for healthcare providers.
-
Pain Management: Since you’ve been advised to take Aleve or ibuprofen, you might continue this for short-term relief. Ensure to follow the recommended dosages. If you notice that medications are not helping or you're experiencing side effects, this is worth mentioning to your doctor.
-
Consider MRI: Discuss the possibility of obtaining an MRI with your healthcare provider. Given that you have persistent pain without improvement, an MRI can provide a more detailed image of soft tissues that an ultrasound may not fully capture, allowing better insight into any ongoing issues.
-
Second Opinion: If symptoms persist or worsen, consider seeking a second opinion from another physician, perhaps a specialist in musculoskeletal conditions or a rheumatologist who can provide a fresh perspective on your situation and suggest additional tests if necessary.
-
Physical Activity Adjustment: While maintaining physical activity is great, consider modifying your routine to avoid any exercises that exacerbate your pain. Sometimes gentle stretching or physical therapy can aid recovery without adding strain.
It's clear that you're taking proactive steps toward understanding and managing your discomfort, and I encourage you to continue doing so. Make sure to advocate for your health, and don't hesitate to reach out for further evaluations if the pain continues to disrupt your life.

Concerns about Lymph Node Changes
I'm a 30-year-old woman sharing my health concerns. In early 2025, I began experiencing difficulties with swallowing—there was a sensation of something lodged in my throat that caused pain each time I attempted to swallow. Along with this, I dealt with extreme fatigue, a persistent feeling of congestion without any accompanying cough, night sweats, and my temperature fluctuated with inconsistent fevers. An initial ultrasound revealed a lymph node that was mildly enlarged. While I awaited feedback from my primary care physician, I discovered a minuscule bump on my neck and became anxious. This led me to seek immediate care where a CT scan was performed, showing that the lymph node appeared to be normal. Fast forward three months, and that same lymph node has grown slightly larger. I can now both see and feel the bump when I turn my neck, though it’s not causing any pain. The symptoms I previously experienced—ongoing congestion, tiredness, and night sweats—persist even after seven months, while the swallowing difficulties and fevers have lessened in frequency.Generally, my blood tests came back normal, but I did find that my iron and ferritin levels were low, alongside a high TIBC count. This was surprising to me, as my diet usually includes foods rich in iron. My doctor suggested we should repeat the ultrasound in a few months if the neck bump remains apparent. To be candid, I'm feeling quite anxious about the situation. Both of my grandfathers passed away due to cancer (though neither had lymphoma), and recently, a second cousin of mine was diagnosed with non-Hodgkin's lymphoma. Given my circumstances, should I advocate for a biopsy? Is there a reason to feel reassured since the CT scan didn’t reveal anything worrisome three months ago? Could it have possibly been overlooked? Thank you for your insights!
Unexplained Discomfort
I want to share my experience with an ongoing, enigmatic pain located on my right side, specifically between my hip and thigh. To get clarity, I’ve undergone several imaging tests, including: - CT scan - Ultrasound - Transvaginal ultrasound - Hip X-ray - Back X-ray Unfortunately, all the results appeared normal. When my doctor reviewed the hip scan, they suggested the possibility of a bone island, a benign condition that shouldn’t cause issues. Yet, despite this explanation, I’m left feeling puzzled and increasingly frustrated. The pain has escalated to a point where it disrupts my sleep, leaving me in considerable discomfort. Despite repeated consultations, the conclusions remain the same: - "You’re only 20; it’s probably pregnancy" (which I assure you, isn’t the case). - "Maybe it’s your appendix" (definitely not). - "Everything shows normal results". The discomfort has intensified to a sharp, stinging sensation, and I’m feeling lost about what steps to take next. Financial constraints limit my options for exploring specialized treatments. I’m honestly at a loss and would appreciate any insights or suggestions. Does anyone have an idea of what might be going on? Your questions or advice would mean a lot to me.
Navigating Lower Back Pain Management as a 24-Year-Old with Autism
At 24 years of age, I find myself grappling with persistent pain in my lower back. I suspect that this discomfort stems from lifting a particularly heavy object while not maintaining proper posture. My diagnosis of autism complicates my ability to effectively plan and manage this condition. I am seeking guidance on how to apply the recommendations outlined on the NHS website regarding lower back pain treatment. Some of the strategies I wish to consider include: - Taking anti-inflammatory medications such as ibuprofen to alleviate discomfort. - Applying an ice pack, or a bag of frozen peas wrapped in a towel, to help diminish both pain and swelling. Additionally, incorporating walking into my routine could be beneficial. I also learned there are exercises demonstrated in a video that provides stretching techniques specifically for back relief, along with links to other helpful videos. Could someone advise me on the duration and frequency for each of these methods I have mentioned?
Inquiries Regarding Ultrasound Procedure
When an ultrasound technician is capturing images and taking measurements on the monitor, is it reasonable to think they might be identifying a potential issue?

Exploring Low Blood Pressure Symptoms
I’m a 24-year-old female experiencing several concerning symptoms: - Lightheadedness and dizziness - Discomfort in my legs, feet, and right arm - Increased fatigue compared to my normal levels Recently, during a dental appointment, I had my blood pressure checked, and it was found to be lower than average. This is unusual for me as I've never encountered similar issues or symptoms before, and they seem to have emerged over the past few weeks, roughly from mid-August until now. After my visit to the dentist, I did a bit of research and discovered that these symptoms might indicate hypotension. For some background, I have a history of prediabetes, polycystic ovary syndrome (PCOS), and I also deal with depression and anxiety. I found information suggesting that fluctuations in hormones or diabetes could be contributing factors to this condition. I received my diagnoses a few years back. I’ve noticed that upon rising from bed, my legs experience a moderate ache, and standing for about 15 to 20 minutes at work tends to strain my thighs significantly, which feels quite unusual. Additionally, there's a peculiar sensation at the top of both thighs—I can’t quite articulate it, but it feels somewhat like wearing pants that are too tight, even though I do not wear constricting clothing. It’s as if there's something pressing on both thighs. My mother thinks I might be overreacting due to the dentist’s remarks and my subsequent research, but she has acknowledged that I've been experiencing these symptoms for a while now. I welcome any advice or insights on this matter. Apologies for the lengthy explanation, but I wanted to provide as much relevant information as I could.
