Minor Hard Lump in Armpit
Greetings! I'm a 32-year-old woman, and I recently noticed a minuscule, firm lump in my left armpit about three weeks ago. This bump is immobile and does not resemble a pimple (there's no white head). Interestingly, it’s neither red nor inflamed and is not visible to the naked eye; it can only be detected by touch. I haven't experienced any illness in several months. I'm feeling a bit anxious, especially since my father was diagnosed with non-Hodgkin's lymphoma due to swollen lymph nodes. While I understand my situation involves a small bump rather than widespread tenderness, I can't help but worry because it's located in the same region. I would greatly appreciate any insights you might have!

It's understandable to feel concerned when you notice a new lump, especially given your family history. However, many small lumps in the armpit area are benign and not serious.
Main Points:
You discovered a small, firm, immobile lump in your left armpit that is not inflamed or visible. While it's natural to feel anxious, it's important to note that there are several common causes for such lumps, many of which are harmless.
Explanation:
Lumps in the armpit can arise from various sources, including:
- Lymph nodes: Your body has lymph nodes in the armpit that can become slightly enlarged or firm due to infections or other benign causes.
- Sebaceous cysts: These are small bumps that can develop from clogged oil glands.
- Fibroadenomas or lipomas: These are usually harmless growths of tissue and fatty tissues, respectively.
While your family history of lymphoma increases your awareness, it's important to remember that most lumps are not cancerous, especially when they are firm, immobile, and not associated with significant symptoms like redness or pain.
Next Steps:
-
Monitor the Lump: Keep an eye on the lump for any changes in size, shape, or texture. Take note if you experience any other symptoms such as fever, weight loss, or night sweats.
-
Self-Examination: Continue to perform gentle self-examinations regularly to stay aware of any changes.
-
Lifestyle Adjustments: Focus on maintaining a healthy lifestyle, including a balanced diet, regular exercise, and good hydration, which can support your immune system.
-
Reassurance Techniques: Engage in relaxation techniques if anxiety persists, such as deep breathing or meditation to help manage your worries.
-
Documentation: Consider keeping a diary of your observations regarding the lump (size, any changes, and symptoms) to help if you decide to seek further information later.
If the lump increases in size, becomes painful, or you have significant symptoms arise, reach out for further medical evaluation. Let me know if you would like more specific advice or have any other concerns!

Could an Abdomen/Pelvis CT Detect Lymphoma or Indicate Lupus?
I am a 33-year-old woman, standing at 5'4" and weighing 145 pounds. At present, I am not taking any medications and I do not smoke or drink alcohol. For approximately five months, I have been experiencing severe discomfort, which includes persistent pain in my lower back, hips, left side of my rib cage, and shoulders. This has coincided with a decrease in my appetite, ongoing fatigue, noticeable hair thinning, and unintentional weight loss. Recent blood tests have revealed elevated neutrophil levels alongside diminished lymphocytes, raising concerns for me, especially since I have not been ill. In March, I visited the emergency room due to abdominal pain. During that visit, I underwent a contrast-enhanced CT scan of my abdomen and pelvis. The results indicated no apparent cause for my discomfort, and I was advised to seek further evaluation from a gastroenterologist. However, I have refrained from reviewing my CT results, as I prefer to avoid triggering anxiety. My apprehension about lymphoma stems from my family’s history of cancer, compounded by the knowledge that my erythrocyte sedimentation rate (ESR) was elevated six months ago, although I did not pursue follow-up tests at that time. With my doctor having recently departed from their practice, I find myself in search of a new physician, but I am uncertain about which tests I should request.
Unexplained Bruising: Seeking Insights
Greetings! I'm a 20-year-old female, generally in good health and maintaining a fit lifestyle with a height of 5’6” and a weight around 121 lbs. Approximately twelve days ago, I discovered a small bruise on my left leg, which had what appeared to be a bite mark or a tiny puncture at its center. Initially, I dismissed it as inconsequential. During the first couple of days, I felt fairly normal, although I did experience some discomfort, along with a severe headache, and an odd sense of malaise—similar to having a mild cold. As the days passed, however, my condition deteriorated significantly. I began to feel very ill—experiencing nausea, episodes of overheating akin to hot flashes, and an overall sense of unwellness, despite not having a fever. The bruise and surrounding area began to noticeably worsen, with a stark contrast evident between the eleventh and twelfth days. The situation escalated on the twelfth day, coinciding with a severe leg cramp. The bruise on my leg has enlarged, darkened, and become increasingly painful. Additionally, my leg feels crampy, and now, after twelve days, I've sensed slight numbness in my left foot. I also noticed smaller bruises appearing on my other leg and my arm, which emerged suddenly from day eleven to day twelve without any clear explanation for their appearance. This is an unusual experience for me—I have never encountered a bruise that changes or expands in such a manner. I am uncertain whether this is simply an odd bruise or indicative of a more serious issue. Could anyone provide insight into what might be happening? Thank you for your help!
Understanding Antibiotic Recovery Time: What to Expect
As a 19-year-old female from the Philippines, weighing 52 kg and standing at 148 cm, I was recently given a 7-day prescription for amoxicillin by my physician. The diagnosis revealed a throat infection characterized by redness and yellow patches. Additionally, I've noticed three lumps in my neck that emerged simultaneously with the throat symptoms, coupled with difficulty swallowing and some numbness in that area. These lumps are situated on the right side of my neck, just below my chin, and near the left side, at the jaw's end. I’ve been on the antibiotic for several days now. While I do observe a little progress, I still experience discomfort and persistent pain, particularly when I swallow or move my neck. I'm making an effort to drink plenty of fluids and get as much rest as possible. I'm curious about how long it generally takes to feel entirely better. Should I be noticing significant improvement by the halfway point of the amoxicillin treatment, or can it sometimes take until the conclusion of the entire 7-day cycle to feel fully recovered? This information would help me determine whether I need to visit another doctor, as I am contemplating seeking a second opinion. My anxiety levels have increased since I’ve never encountered a situation like this before. I would greatly appreciate any insights or shared experiences that could provide some clarity. Thank you for your understanding!
Concerns Over IV Injection Issues After Pneumothorax Treatment
A 44-year-old woman, standing at 5 feet 2 inches and weighing 160 pounds, was hospitalized for a pneumothorax. During her time in the hospital, she was aware that her IV line was malfunctioning. After informing the nurse about the issue, she observed the nurse still proceeded with administering 0.25 mg of Benadryl, followed by 4 mg of morphine through the compromised IV. Fluids were continued to be infused until the next morning when she firmly indicated that the IV was indeed blown, noting that her forearm had become hardened and swollen. Now, two weeks post-discharge, she has experienced complications and found a 2-inch section of her vein to be rigid and sensitive to touch. She is contemplating whether it would be prudent to visit her primary care physician to have this issue recorded.
Recurring Eyelid Swelling: Seeking Guidance
I’m a 21-year-old male, standing at 6'1" and weighing 220 pounds. Lately, I've been experiencing intermittent swelling in my eyelid, which appears to occur without any clear reason. Unsure of how to proceed, I consulted a dermatologist, but they dismissed it as a consequence of allergies. However, I have encountered allergy-related eyelid swelling before, and this feels distinctly different. I'm beginning to suspect that it might be some kind of fluid accumulation in that area. I've noticed that applying a warm cloth often alleviates the swelling entirely. I’m reaching out for assistance because I'm worried about the potential for lasting damage to the skin surrounding my eyelid.
