Understanding Lymph Node Examination and Imaging Concerns
Title: Do medical imaging procedures also reveal unrelated issues? What’s the correct technique for checking lymph nodes—is it a gentle press or a firmer touch? Background: I’m 26 years old and have accrued seven years of experience in pest control, which involves exposure to pesticides. I'm a non-smoker and have a 2mm pituitary tumor that has not shown any signs of growth as far as I know. Last December, I was involved in a high-speed car crash that led to my admission in the emergency room. During my evaluation, various CT scans were conducted: one of my head without contrast, one of my spine without contrast, and one of my abdomen and pelvis with contrast. Fortunately, all these scans yielded normal results, and no issues were detected at that time. Notably, my bloodwork indicated elevated neutrophil levels at 73.1% while lymphocyte levels were low at 17.9%. I do not recall any lymph node concerns during this visit, and everything else appeared to be normal. In February, my household was affected by a common illness. By March 6th, I became aware of a swollen, painless lymph node located on the left side of my neck. Despite the passage of time, it remains enlarged. On March 25th, I visited my general practitioner regarding the swollen lymph node. At that appointment, she noted that I was experiencing illness again—my son had contracted RSV, and it seems I've caught it too, though I'm still on the mend. She suggested that we wait another month to see if the swelling subsides; if it doesn't, I will then undergo an ultrasound for further evaluation. I have a couple of inquiries: Given my health anxiety and the assumption of possible lymphoma, if the lymph node was present during my car accident, would it have been identifiable in the imaging, or could it have been overlooked? Additionally, could you clarify the proper technique for assessing a lymph node? Should it be a gentle touch when feeling for its characteristics?

Main Points: Medical imaging can sometimes reveal incidental findings unrelated to the primary reason for the exam, and the proper technique for checking lymph nodes involves a gentle touch to assess their characteristics without causing discomfort.
Explanation:
-
Medical Imaging and Incidental Findings: Imaging tests, like CT scans, often look for specific issues, but they may unintentionally show unrelated findings. Enlarged lymph nodes could potentially be noticed during such imaging. However, their visibility depends on several factors, including the size of the lymph node and the area being scanned. If the lymph node was not visibly enlarged at the time of the crash, it may not have been reported.
-
Assessing Lymph Nodes: When checking for lymph nodes, using a gentle press is recommended. Firm pressure could cause discomfort and might not provide a better sense of the lymph node's characteristics. You should feel for size, shape, and any tenderness while ensuring to check with light pressure.
Next Steps:
-
Monitor the Swollen Lymph Node: Continue to observe the swollen lymph node. Take note of any changes in size, tenderness, or new symptoms in the coming weeks. It's OK to expect that it might resolve, especially if it's related to a recent illness.
-
Follow Up as Planned: Since your doctor suggested waiting for another month for reevaluation, adhere to this plan. Should the lymph node remain enlarged after this period, proceed with the scheduled ultrasound for further assessment.
-
Managing Anxiety: Given your health concerns, consider discussing methods for managing health anxiety with a professional. This can help ease your mind while waiting for more information about the lymph node.
-
Stay Informed: If you have any signs of fever, night sweats, or unintentional weight loss, report these to your healthcare provider immediately, as they can be important clues for further investigation.
By being proactive but also patient, you can navigate this situation while keeping your health goals and concerns in focus.

Unexplained Urticaria Episodes
A 28-year-old woman, measuring 158 cm and weighing 72 kg, has been experiencing episodes of urticaria for the past month without any obvious cause. The issue began following a localized reaction to her migraine treatment, particularly the medication erenumab. Generally, she has minor reactions to this injection; however, the last two doses have led to significant flare-ups. Subsequently, she began to notice hives appearing sporadically, primarily without identifiable triggers. These episodes tend to intensify during the night but usually subside after taking cetirizine, an antihistamine. Additionally, she has known drug allergies to ciprofloxacin and penicillin. Recently, after taking cefpodoxime, she developed a rash within a few hours, although cefixime did not provoke any adverse reactions.
Concern Over Possible Botulism Exposure: Seeking Guidance
Greetings, everyone! I'm a 37-year-old male, weighing approximately 80 kilograms and standing at about 1.75 meters tall. To provide some context, I'm currently visiting a friend in another country, but I don’t have any travel health insurance. My friend had to work through the weekend and encouraged me to help myself to whatever food I found in her refrigerator. Upon arriving, I discovered some gravy that appeared and smelled fine. I decided to prepare some frozen fries in the oven while simultaneously heating the gravy in a dish, which I placed in the oven at a temperature of around 225 degrees Celsius. Following the instructions, I set a timer for 20 minutes when cooking the fries. However, when the timer went off, the fries didn’t seem fully cooked. I opted to give them an additional 10 to 15 minutes to bake (the gravy was still on the bottom, and I had completely forgotten about it). Eventually, the fries emerged from the oven, slightly overdone, but I didn't mind. Upon pulling everything out, I noticed that the gravy had begun to burn and char during the process. Afterward, I proceeded to eat the fries along with some of the gravy, which had turned into a paste-like consistency. I later called my friend to catch up and mention what I had for dinner. To my dismay, she panicked when I mentioned the gravy, informing me that it was actually 12 days old and stored in a plastic container. Now I’m left worried about my situation. How serious is this? To provide additional context: - It’s been 12 hours since I consumed the food, and I have not yet experienced any symptoms. What signs should I be vigilant for? - I heated the gravy thoroughly; it was in the oven for over 30 minutes, and the edges of the plate were charred. - Prior to this meal, I hadn't eaten anything for nearly 24 hours, so I'm hoping my stomach's acidity might be a protective factor. I didn't consume a large amount, discarding approximately half of what I had. I would greatly appreciate any advice or insights regarding this situation.
Rash on the Dorsal Side of My Hands
A 24-year-old male, standing 5'3" and weighing 125 pounds, is not currently taking any medications. While I do not smoke, I am often exposed to secondhand smoke from those around me, and I have recently spent time in an environment where a significant amount of unpleasant smoke is produced due to casting activities. For approximately three weeks, I have been experiencing a rash on the backs of both my hands. I initially became aware of it after working on my car's engine. The rash has led to dryness and itching, and I took a photo after my shower today, highlighting the redness that has become particularly noticeable. What are some effective treatments for this condition?
Understanding Foam in Urine: When is it a Concern?
Age 24, I've observed a notable increase in the amount of foam in my urine over the past couple of years, compared to what I remember from before. About a year ago, I mentioned this to my primary care physician, who seemed somewhat dismissive of my concerns. Nonetheless, they proceeded to conduct a urinalysis, which returned normal results, indicating no elevated protein levels. I frequently undergo blood tests, and both my eGFR and creatinine levels typically fall within the normal range, although I did experience some fluctuations linked to a bout of mononucleosis a couple of years back, where my eGFR dipped near 70; it currently remains above 100. I suspect that changes in my urological function, likely from aging, are contributing to a stronger urine stream now than in my youth. The foam generally settles down after a few minutes, although occasionally it lingers longer than expected. I make a concerted effort to stay hydrated, even though I don’t always succeed, so I wonder if mild dehydration could partially account for the foaming. This concern is particularly relevant as I'm resuming strength training and planning to increase my protein consumption. I want to ensure that my kidneys are not overtaxed due to any potential underlying issues. Additionally, I have a history of taking 5 grams of creatine daily, paired with plenty of water, which makes me cautious about this, too. Is there a point at which foaming in urine is considered excessive, or does a specific threshold exist that I should be aware of?
Understanding Symptoms of Salmonella: What to Do Next
My boyfriend, who is 26, experienced a fever that peaked at approximately 99.5°F yesterday morning. Thankfully, after resting and taking NyQuil, his fever subsided by this morning. However, he has been dealing with severe abdominal pain and persistent diarrhea since last evening, which has not shown much improvement. He has been making frequent trips to the restroom, nearly every hour throughout the night and again today. While I initially thought he might be improving since the fever has decreased, I became alarmed upon noticing bright red blood in his stool and on the toilet paper after he wipes. It has been around 40 hours since the fever began, and my concern has heightened now that blood has appeared. I’ve come across some online information suggesting these symptoms might be typical for salmonella infections, and I’m uncertain whether we should seek medical attention immediately or if it’s advisable to wait another day or two to see if his condition improves. I realize that consulting a doctor as soon as possible would be the best course of action. However, he currently lacks insurance, which makes him hesitant to get checked right away. Any guidance on this matter would be greatly appreciated, thank you.
