Is a CT Scan Necessary After Four Ultrasounds?
At 23 years old, I've been monitoring a lymph node located in my left groin for over a year. To assess its status, I've undergone four ultrasound examinations, all indicating that the lymph node is reactive without any alarming signs. - The initial ultrasound, conducted in March 2024, revealed mild lymphadenitis. - The second evaluation in March 2025 noted that the largest node measured 0.7 cm and appeared benign. - In April 2025, the third ultrasound showed three nodes, with the biggest measuring 1.8 x 0.7 cm; it was still classified as reactive and its hilum was preserved. - Lastly, a comprehensive abdominal and pelvic ultrasound in May 2025 returned normal results, identifying only a few sub-centimeter nodes in the groin, which also displayed a fatty hilum. Importantly, I have not experienced any concerning symptoms such as fever, unintentional weight loss, or night sweats. My blood work shows normal results with the exception of a slight iron deficiency. Despite this reassuring information, my physician has recommended that I proceed with a CT scan using both oral and intravenous contrast for further investigation. However, I'm left questioning whether this additional imaging is truly warranted or if it might be excessive.

It's understandable to question the necessity of a CT scan after having multiple reassuring ultrasounds, especially given your history and the findings so far. Here's a clear breakdown of the situation:
Main Points:
- Your previous ultrasounds show reactive lymph nodes without alarming features.
- CT scans provide more detailed imaging, but may not always be necessary after multiple ultrasounds.
- Discussing your concerns with your physician is essential to make an informed decision.
Explanation:
Reactive lymph nodes can often signify a response to infection or inflammation and typically do not suggest a serious condition, particularly when accompanied by normal lab results and the absence of worrisome symptoms like weight loss or night sweats. Ultrasounds are useful for monitoring lymph nodes, especially since yours have remained stable over time.
A CT scan delivers a more comprehensive view and can sometimes help rule out other issues, but it also comes with exposure to radiation and additional costs. The recommendation for a CT scan might stem from a desire for a more definitive assessment, but it's crucial to weigh its risks and benefits.
Next Steps:
-
Consider Your Concerns: Reflect on how you feel about the necessity of the CT scan. It's okay to be cautious and seek clarification.
-
Consult Your Physician: Schedule a follow-up discussion with your physician to express your doubts about the CT scan. Ask:
- What specific information do they hope to gain from the CT that the ultrasounds haven't already provided?
- Are there alternative monitoring strategies that might be just as effective?
-
Monitor Symptoms: Keep tracking any changes in your health, especially symptoms that might develop in the future. Documenting any new concerns can help during discussions with your physician.
-
Seek A Second Opinion: If still uncertain, consider getting a second opinion from another healthcare professional, particularly one who specializes in internal medicine or oncology.
Taking these steps will empower you to make an informed decision regarding your health while ensuring you feel comfortable with the plan moving forward.

Exploring Princess Rongshou's Appearance and Health
Princess Rongshou, known as the First Rank Princess (Chinese: 榮壽固倫公主; 1854 – 1924), has always piqued my interest due to her distinctive facial characteristics. This curiosity led me to ponder whether her appearance might be linked to a genetic condition or if it simply reflects her unique beauty. I would be grateful for insights from experts or history enthusiasts who might identify any possible indicators of a syndrome. Alternatively, it would be equally interesting to consider if she merely exhibited the traits of a perfectly healthy woman with unconventional features. In my research, I managed to locate images of her father, Prince Gong, who can be seen in the portraits available online. However, a careful comparison of his likeness — along with other family members depicted in the photographs — reveals no significant resemblance in those notable features associated with Princess Rongshou. Although there exists a general familial similarity, they all appear conventionally healthy aside from her unique traits. I sincerely appreciate any assistance or perspectives anyone might provide regarding this intriguing subject.
Understanding Radiation Exposure from Medical Procedures
I'm seeking insights from medical professionals regarding the radiation dose (measured in mSv) associated with a certain radiological procedure I underwent. This event took place in Tijuana, Mexico.

Understanding Lab Results Over Time
Over the course of two years, you may observe a decline in your lab results, such as a 3% drop in red blood cells (RBC), a 33% reduction in white blood cells (WBC), and a 16% decrease in platelets. While these changes indicate a downward trend, it’s worth noting that all values remain within the normal range, albeit with RBC and WBC numbers being somewhat on the lower end. This situation raises the question of whether such fluctuations are to be considered typical or concerning.
Understanding the Absence of Hunger Signals
I am a 25-year-old Caucasian woman, standing at 5 feet 4 inches tall, weighing approximately 120 pounds. I do not take any medications and have no underlying health issues, although I do smoke. Lately, I have noticed a strange absence of what I consider typical hunger sensations. The feeling of hunger in my stomach rarely occurs and, when it does, it vanishes quite quickly. Occasionally, I find myself feeling extremely fatigued, dizzy, or lightheaded, prompting me to lie down. In these moments, after I eat, I realize that I had indeed been hungry, even though my stomach hadn’t indicated it. When I start eating, I either feel satiated very quickly or still find myself feeling hungry. This seems to happen when I have not consumed a sufficient amount of nutrients, or perhaps my stomach simply failed to communicate my hunger. I tend to encounter three distinct scenarios related to my energy levels, which I'll summarize under the umbrella of tiredness: 1. I experience no hunger sensations, along with no fatigue or other symptoms. 2. I notice a brief feeling of hunger, which may or may not be accompanied by tiredness. 3. I have no indications of hunger but feel tired; upon eating, my stomach finally starts to register the hunger once I begin consuming food. My diet mainly consists of home-cooked meals that I consider healthy, but I also indulge in fast food and homemade sweets occasionally. Typically, I consume two meals a day, skipping breakfast as I don’t feel hungry until lunchtime. I usually rise around 5 am, which is too early for my appetite to kick in. Is it typical to not experience hunger signals in your stomach?
