Swollen Underarm Concerns
I’m a 28-year-old female. Am I simply noticing additional fat or an unusual shape in my armpits, or is there a different issue at play? The primary concern is with my left underarm, where I’ve felt a firm area that is quite noticeable. It’s about the size of an egg when I apply pressure, yet there’s no redness or discomfort associated with it. My right underarm exhibits some minor puffiness and firmness as well, but it's not nearly as pronounced as what I experience on the left side.

It's understandable to feel concerned about a firm area in your underarm. Swelling or firmness in that area can occur due to various reasons including benign issues like swollen lymph nodes, lipomas (benign fat tumors), or even hormonal changes. Given that there is no redness or pain, it's likely less urgent, but it's important to monitor the situation closely.
Explanation:
The firm swelling you're feeling could potentially be due to swollen lymph nodes, especially if you've had recent infections or illnesses, or it might be a lipoma, which is a harmless growth of fatty tissue. Hormonal fluctuations can also affect breast and underarm tissue, leading to firmness. Noticing changes is important, but many times these issues resolve independently.
Next Steps:
-
Monitor the Firmness: Keep an eye on the size and shape of the firm area. Take note if it changes or if you start experiencing any new symptoms, such as pain, redness, or fever.
-
Self-Examination: Gently check both underarms regularly to note any changes in the firmness or size. Also, feel for any additional lumps or changes in texture.
-
Lifestyle Considerations:
- Maintain a healthy diet and exercise to support overall health, which can sometimes help with body composition concerns.
- Stay hydrated and avoid tight clothing that may irritate the area.
-
Schedule an Appointment (if needed): If the lump grows, remains persistent for several weeks, or if you develop any other symptoms, it may be wise to consult a healthcare professional for further evaluation.
Remember, it’s always best to trust your instincts when it comes to your health, so do reach out for advice if your concern persists or worsens.

Understanding My Symptoms: A Personal Account
A 27-year-old male, standing at 179 cm and weighing 86 kg, has observed a troubling set of symptoms developing after an unfortunate habit of scratching at his scalp wounds. His health concerns escalated significantly after an incident involving vaginal secretions mixed with blood coming into contact with his nails, followed by intense scratching of his head injuries for an extended duration. **Week 1**: Symptoms emerged swiftly. He began to experience a tingling sensation throughout his entire body, and the urge to urinate became increasingly frequent, occurring every hour. The patient also noted episodes of cold sweats and persistent dryness in his mouth, indicating potential dehydration or anxiety responses. **Week 2**: The discomfort progressed to include numbness across the tongue and mouth, accompanied by a burning feeling affecting his tongue. Alongside these sensations, he suffered from joint and muscle aches and bouts of diarrhea, indicating possible systemic involvement. **Week 3**: After scratching the wounds on his scalp and inadvertently rubbing his eyes, he developed irritation that sparked occasional stinging sensations. Alarmingly, his vision started to decline rapidly, to the point where he feared complete loss of sight within days. **Week 4**: Sleep eluded him due to the unsettling electric shocks racing through his limbs, along with uncontrolled reflexes. Tinnitus set in, causing persistent ringing in his ears, compounding his distress. **Week 5**: Seeking medical attention, he visited the emergency room for an eye evaluation, during which a blood test was conducted. A sudden, sharp electric jolt in his right thumb during the blood draw precipitated an ongoing tingling sensation in that digit. Subsequently, extending his arm heightened the electric sensations in his thumb, which then radiated through his entire hand and forearm, further intensifying the alarming symptoms. The following day, the sensations began to manifest in his left hand as well, indicating a troubling spread of symptoms. By the end of this week, the electric shock sensations had extended to his legs, and the tinnitus had become intolerable and progressively worsened day by day. **Week 6**: Currently, his symptoms continue to escalate without relief. His joints are severely impacted, making even walking a painful endeavor. At night, he experiences a pervasive tingling throughout his veins, almost as if his body is alive with an abnormal buzzing sensation. To address these alarming developments, he underwent multiple PCR tests for HIV, administered at 1.5 and 3 weeks, yielding negative results. Follow-up tests for Hepatitis C and Hepatitis B also returned negative after 4 weeks, as did the VDRL test conducted at the 6-week mark.
Rice Lodged in Throat for Hours
I’m a 20-year-old, standing at 5 feet 2 inches and weighing 120 pounds. There's a grain of rice lodged in my throat, and it's causing quite a bit of discomfort. Despite my efforts to swallow it down with water, it just won’t budge. I even attempted to eat some yogurt in hopes of easing the situation, but to no avail. I'm feeling quite desperate at this point – any advice would be appreciated!
Understanding Recurrent Mesenteric Adenitis: A Personal Account
At 23 years old and weighing 140 pounds, I have experienced mesenteric adenitis on multiple occasions throughout my childhood. Although I cannot access my old medical records, I recall being informed that these episodes lasted for weeks, occurring at least four times. Following that, there was an episode that stretched from July to October in 2021, and another for three weeks in 2023, both of which transpired after having COVID-19, and currently, I’m dealing with it again after a brief span of four days. Importantly, I have not encountered any viral infections or illnesses prior to these symptoms surfacing, and I haven't had vomiting, nausea, or fever during these episodes. In 2021, I experienced a significant weight drop of 45 pounds due to this condition, prompting further medical investigations. Although a biopsy yielded no concerning results, my laboratory tests revealed elevated white blood cells, reduced red blood cells, increased lipase levels, and a higher lymphocyte percentage, yet the overall findings were largely unremarkable. A colonoscopy also returned normal results, as did a gastric dumping test. However, my current experience has been particularly challenging. My lab results appear consistent with previous ones. Initially, I suspected my appendix had burst due to the severity of my symptoms. I endured frequent diarrhea, having 18 episodes on the first day, followed by 10 on the second, and 11 on the third day, and only experiencing three episodes today. I have not consumed any food since the midday of the third day. Each time I attempt to eat or drink, I face severe spasms and pain across my upper and lower right abdomen that is debilitating. Even when not eating, a dull ache persists, and standing for more than a few moments triggers an overwhelming urge to use the restroom, despite there being nothing left. On Monday, I plan to reach out to a new gastroenterologist in hopes of expediting an appointment to further investigate potential solutions to my issues. Are there known factors that could lead to increased occurrences of mesenteric adenitis in some individuals? Is it merely unfortunate luck, or should I consider advocating for additional medical evaluations?
