Seeking Clarity on CT Results After Vehicle Collision: Is Lymphoma a Concern?
Background: I am a 26-year-old male and do not smoke. My career in pest control exposed me to pesticides and silica dust during my first two years. Two years ago, a 2mm pituitary lesion was discovered, which my neurologist assured me was non-hormonal and not a cause for concern unless it manifested through vision problems. Recently, for about a month, I have noticed a painless enlargement of a lymph node in my jaw. This coincided with two recent illnesses in late February and late March, leaving me hopeful that it's related to those infections. However, the CT results make me wonder if I should investigate the possibility of lymphoma, which is why I’m seeking advice. Additionally, I was involved in a car accident in December, during which a comprehensive CT scan was performed. Here are the concerning findings from that scan: **Chest:** There are no signs of enlarged lymph nodes in the mediastinum. The presence of calcified lymph nodes in the mediastinal and left hilar regions suggests a past granulomatous infection. **Abdomen/Pelvis:** The central mesenteric root appears hazy, with several clearly defined prominent mesenteric lymph nodes, which might indicate mesenteric panniculitis or adenitis. Could the impact from my seatbelt at the time of the accident have led to this condition? **Brain:** The detail in this area is limited due to interference. There is a slight prominence of the ventricles and sulci, but no midline shift or areas of unusual density. There are also no signs of bleeding or extra-axial fluid collections. This CT scan was conducted two months prior to my recent issue with a swollen submandibular gland or lymph node under my jaw that has persisted for over a month now. My general practitioner advised me to allow it to resolve naturally over the next month and mentioned that if I were to have lymphoma, it would likely have been visible on the CT scan three months ago. Is his assertion accurate?

Based on the details you've provided, it sounds like you have several health concerns related to your recent symptoms and imaging results. Here’s a breakdown of the key points:
- Lymph Node Enlargement: You have a swollen lymph node under your jaw that has lasted for over a month.
- CT Scan Findings: Your CT results from the car accident indicated no signs of lymphoma in your chest and noted potential past infections, while the abdominal findings raised some questions about lymph node activity.
- Previous Lesions and Performances: You have a history of a non-concerning pituitary lesion.
Explanation
Swollen lymph nodes are often a response to infection or inflammation, and given your recent illnesses, it is reasonable to consider that this swelling may be related to those infections. The general practitioner’s assertion that a lymphoma would likely have been visible on your past CT scan is generally accurate. CT scans can often reveal prominent lymph nodes associated with lymphoma or other malignancies, but not all conditions are visible at all stages of their development.
The calcified lymph nodes in your CT suggest past infections, which is common and often not a cause for concern. The prominence of mesenteric lymph nodes could relate to various benign conditions, but it can also merit further investigation if you have ongoing symptoms.
Next Steps
-
Self-Monitoring: Continue to observe the swollen lymph node. Note any changes in size, tenderness, or new symptoms like fever, night sweats, or weight loss.
-
Pain Management: If you experience discomfort with the swollen gland, over-the-counter pain relievers like acetaminophen or ibuprofen may help.
-
Hydration and Nutrition: Keep well-hydrated and maintain a balanced diet to promote your immune response.
-
Follow Up: If the lymph node has not decreased in size after a month or if you develop any concerning symptoms, reach out to your healthcare provider for further evaluation. This may include blood tests or imaging studies to determine the cause of the lymph node enlargement.
-
Further Investigations: Discuss with your doctor the possibility of performing blood tests to check for signs of infection or lymphoma, or getting another imaging test if the swelling persists.
Your proactive approach to your health is commendable. Remember, while it’s natural to worry, many lymph node enlargements are benign and resolve on their own, especially following infections. Please feel free to reach out if you need further clarification or support.

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.
Navigating Alcohol Challenges
My partner has recently developed issues with alcohol. Over the past year, he has been consuming significant amounts—roughly two bottles of distilled spirits each week, in addition to beer. A decade ago, he struggled with inhalants and even faced near-fatal consequences, but he had maintained sobriety until he turned to drinking. He believes he has plenty of time before the effects of alcohol will manifest. How long can he continue this way before it becomes a serious problem? He is a 53-year-old male, weighing 325 pounds, standing at 5 feet 11 inches, and he is currently on medication for hypertension. Although we plan to separate later this year, it’s clear that this situation will have an impact on our three children.
