CT Scan for Persistent Headaches: Key Considerations
Age: 34, Male For more than a month, I’ve been experiencing recurrent headaches, accompanied by a strange tingling sensation in my left leg. Concerned about these symptoms, I went to the emergency room, where they performed blood tests and conducted a CT scan without the use of contrast. Three years ago, I underwent a CTA/CT scan with contrast, and the medical team had previously collected those images and sent them to a radiologist for comparison with the latest scans. If a brain tumor were responsible for my symptoms, would the CT scan have been able to detect it?

The CT scan you had can often detect significant abnormalities in the brain, including tumors, but there are limitations to what a CT scan can show. Your symptoms, recurrent headaches and tingling in your left leg, may warrant ongoing evaluation, especially considering the persistence of these symptoms.
Explanation:
-
CT Scan Capabilities: A CT scan is effective at identifying large masses or lesions in the brain, including tumors. However, smaller tumors or early signs of some conditions may not always be visible on a CT scan, particularly if they are located in less commonly scanned areas.
-
Symptom Context: The headaches and tingling could be caused by a variety of factors, including tension headaches, migraines, neurological conditions like multiple sclerosis, or other issues unrelated to tumors. Given that you've had these symptoms for over a month, it’s crucial to continue monitoring them.
Next Steps:
-
Track Your Symptoms: Keep a detailed diary of your headaches (frequency, duration, intensity) and the tingling in your leg (occurrence, duration, and any other accompanying symptoms). This can help identify patterns or triggers.
-
Consider Follow-Up Imaging: Discuss with your healthcare provider whether further imaging studies like an MRI could be beneficial. MRIs are more sensitive than CT scans for detecting certain brain conditions.
-
Monitor New Symptoms: Pay attention to any new or worsening symptoms, such as changes in vision, difficulty speaking, or weakness. If these occur, seek immediate attention.
-
Seek Neurological Evaluation: If your symptoms persist or worsen, consider asking for a referral to a neurologist for further assessment and tailored diagnosis.
You’re not alone in facing these concerns, and it's clear you’re proactive about your health. Tracking your symptoms closely and pursuing further evaluation will guide you towards understanding your condition better.

Unusual Painless Lump Beneath My Jaw
I'm an 18-year-old female with no significant health issues, though I do partake in vaping. For a number of years, I’ve noticed an odd lump along my right jawline, which I initially assumed was merely lymphatic fluid. It isn't visible on my face, but occasionally, after using my gua sha tool, it would feel firm — although it usually diminished after several sessions. Earlier today, while casually feeling around my neck and jaw, I came upon this bump again. This time, however, I recognized it had a different texture — resembling a small, very solid ball, akin to a marble. It doesn’t cause me any discomfort and is quite mobile in the area beneath my chin. It's been persistent for a long time, and as far as I'm aware, I haven't encountered any related symptoms. What could this possibly indicate? I haven’t found anything comparable in my searches online. A quick addition: I should clarify that my family does not have a history of cancer, aside from typical skin-related issues. I often come across suggestions online that it may be a swollen lymph node, but given how long it’s been present and the lack of any recent illness or complications, I remain uncertain.
Seeking Advice for Knee Issues
Hello, I’m Alex, a 20-year-old male. I’m reaching out because I've had two MRIs that showed no problems, yet my knee continues to buckle and remains swollen. I've dealt with this since I injured it while playing volleyball, and I’m also experiencing a sharp, stabbing pain. I’m curious about what steps I should take next or any suggestions for relief.
Should I Consider Another Lymphoma Test? Persistent Tonsil and Lymph Node Swelling
At 20 years old, standing 5'6" and weighing 126 pounds, I’m currently taking medications including Adderall, Motegrity, Propranolol, and Wellbutrin. I also live with hypermobile Ehlers-Danlos Syndrome (hEDS) and come from a family with a history of various cancers, notably leukemia and lymphoma. **Background Information:** In 2019, I underwent an ultrasound on the lymph node area behind my ear, which resulted in a diagnosis of a "benign-appearing reactive occipital lymph node" measuring approximately 1.9 x 0.7 x 0.3 cm. It hasn’t changed size, and the discomfort is usually only present when I am ill; it remains solid and minimally mobile. Moreover, I tend to experience very reactive lymph nodes in my neck that become swollen and painful during illnesses, although currently, they are not causing any issues. I was also prone to strep throat in my childhood but never had my tonsils removed. **Timeline of Health Issues:** - In August 2024, I caught a cold. - By September, I developed tonsillitis that left me feeling miserable, although my tonsils were not as swollen as they are now. - I experienced a strep throat scare in June 2025, which resulted in a negative test; however, the doctor administered antibiotics under the assumption that I may have caught it early. - This past August, I noticed persistent irritation in my throat and found one of my tonsils to be noticeably inflamed. - After testing for strep, which returned negative, doctors did not suspect mononucleosis due to a lack of additional symptoms—no fever, no fatigue, and only rare occurrences of a scratchy throat. On occasion, I struggle to clear my throat or experience slight pain, but these episodes pass swiftly. Now, nearly a month has passed, and rather than decreasing, the inflammation in my tonsil has intensified. While I’m uncertain about the size of my lymph node, I do feel its presence when I position my head in specific ways. I plan to share some images for reference in the comments. I have set up an appointment with student health services, yet I’m curious if I should consult my general practitioner back home instead? Any advice or insights would be immensely appreciated! Thank you in advance!
Could Globus Sensation Be Confused with Throat Cancer?
At 18 years old and having smoked for roughly 2 to 2.5 years, I've started to feel a strange tightness in my neck and noticed a small, movable lump on the left side near my lower jaw. Throughout the summer, I've been dealing with a persistent cough and occasional breathing issues, which I attribute to my smoking habits. Presently, I'm making efforts to quit smoking, but I notice my symptoms often worsen when I abstain for an extended period. Recently, I experienced a brief episode of tongue numbness, which heightened my anxiety. Though I can't pinpoint the cause, I constantly feel as if something is lodged in my throat. Initially, I believed this was due to my prominent Adam's apple, but I'm uncertain. Despite this uncomfortable sensation, I've not encountered any trouble with drinking or swallowing, which makes the experience even more puzzling. I'm seeking insights into what might be causing these feelings. Any feedback or suggestions would be greatly valued!
Should I Be Concerned About Bright Green Stool?
At 21 years of age and assigned female at birth, I've experienced a peculiar gastrointestinal issue for the past two days involving stool that is an intense, vibrant green. While I've read that some green stools can be typical, this particular shade resembles something straight out of a paint swatch—almost like candy! I understand that green stool can indicate that food passed through the digestive tract too quickly. However, considering I’ve been experiencing slight constipation lately and haven't had many bowel movements, this explanation doesn't fit my situation. I'm also feeling unusually bloated, adding to my apprehension. A couple of days ago, I took an excessive dose of Benadryl (a decision I won't repeat) and I'm currently on Lexapro. Additionally, I've recently incorporated new multivitamin gummies into my routine. Generally, my bowel movements aren't affected much by food dyes, as I only notice greenish stool perhaps once a year. Thus, I find it difficult to attribute this change solely to dietary factors. Should I be worried about these symptoms, or am I perhaps overreacting?
