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.

Understanding My Symptoms: A Personal Account
I’m sharing my experiences here, as I haven’t received much feedback elsewhere. I am a 15-year-old female, measuring about 5 feet tall (152 cm) and weighing between 105 and 110 pounds (47-50 kg). I identify as Hispanic and Cuban, and legally fall under the white classification. I reside in Palm Beach County, Florida, and I am a U.S. citizen. I have a diagnosis of Autism and previously had ADD, although that diagnosis has been dropped, which leaves me unsure about my current condition—whether ADHD applies or not. Additionally, I have a past history of anemia, although it is currently not diagnosed. For the past year, I've experienced a range of symptoms that appear intermittently and are often present almost daily. While these symptoms vary, they haven’t subsided. I’ve noticed that both physical activity and caffeine can either trigger or exacerbate these issues. Now, I’d like to detail the symptoms I've been facing. One of my major concerns is my balance; when I stand, I often feel unsteady, and sometimes I even limp. This particular symptom is quite troubling as it occurs frequently. I also experience occasional dizziness and fatigue, which leaves me feeling too weak to move, causing me to remain still for prolonged periods. During episodes of significant fatigue or balance issues, I find myself starting to stutter and I suspect my speech may slur at times. Additionally, my hands sometimes shake, especially when I struggle to walk. There could be other symptoms I haven’t recalled yet, but this is what I remember for now. I will provide updates if I think of anything else, and I welcome any engagement. Furthermore, I’ve noticed irregularities with my heart rate. Initially, when these symptoms began, my resting heart rate dropped from the 80s and 90s to the 50s and 60s; this lower rate has persisted. Lately, however, even simple tasks such as standing, walking short distances, or rocking back and forth (which I do as a self-soothing mechanism) have caused my heart rate to spike to the 100s. These changes are new, while the other symptoms have been consistent for about a year. I genuinely seek guidance or support, as I feel uneasy relying on AI for self-assessment. Unfortunately, I can't afford doctor visits at this time, and my caretaker has shown little concern for my well-being. Therefore, please refrain from suggesting medical consultations. Thank you for taking the time to read my story. I’m open to any questions.
Understanding Lymph Node Sensitivity
A 32-year-old female with a BMI of 28 poses a concern about potential lymph node activity. Over the past three months, she has noticed tender areas coinciding with her menstrual cycle. She has detected slight lumps, but is careful not to press deeply into the tissue to avoid further discomfort. Initially, in December, the sensitivity was localized to the left side of her breast. In January, she observed similar tenderness in her inner left thigh, and by February, both areas and the region above her armpit were affected. Additionally, she has been experiencing fluctuations in her hormonal balance lately. The discomfort in her left breast has persisted for most of this time since December. She wonders whether this is a typical response from lymph nodes due to hormonal changes or if it would be advisable to consult her general practitioner for further evaluation.
What Could This Bump Be? Should I Be Concerned?
I’m a 22-year-old male, standing at 6 feet 2 inches tall and weighing 180 pounds. I currently don’t take any medications and have no significant medical history. Recently, I discovered two small, white bumps on my finger, which appeared around two days ago. They feel firm, much like the sensation of a splinter lodged underneath the skin, and they stick out slightly above the surface. One bump is located at the joint of one finger, while the other is positioned at the tip of another finger on my opposite hand. These bumps are neither painful nor bothersome, but I’m curious to know whether I should consider having them removed or if they might resolve on their own over time. I would appreciate any guidance regarding this matter. Thank you!
Is This a Hemorrhoid or Something Different?
Greetings everyone, I'm a 24-year-old male weighing 82 kg, and I’ve noticed a small, pinkish growth at the edge of my anus that appeared last Wednesday. This bump doesn’t seem to be deeply rooted, is only mildly painful, and mainly causes an uncomfortable sensation when I cough or tense the area. Notably, I haven’t observed any pus, significant swelling, or fever accompanying this. Currently, I am on a regimen that includes sertraline, Bifilac (a probiotic), and omeprazole. It's worth mentioning that I had an abscess before—located in my abdominal area—and that experience was quite distressing. Because of this, I find myself feeling anxious and concerned that I might overlook any early indicators this time around. Interestingly, the same day the bump appeared, I also began experiencing nasal congestion and a general sense of fatigue, resembling mild cold or viral symptoms. Do you think this situation aligns more with the characteristics of a hemorrhoid or perhaps a skin tag (papule), rather than an abscess? What typical signs and sensations might accompany early-stage hemorrhoids? I apologize for any discomfort caused by this topic, but I’m not looking for a diagnosis, just some insight into whether this aligns with common issues. Thanks for your help!
Seeking Guidance on Recurring Pilonidal Sinus Issues
I'm a 17-year-old male of Indian descent, standing at 5'8" and weighing 103 kilograms, and I'm dealing with pilonidal sinus problems. My issues began when I noticed blood on the toilet seat; I initially dismissed it as perhaps an anal fissure. However, after four months, I visited a doctor who diagnosed me with a pilonidal sinus. My symptoms included an unpleasant odor and bloody discharge that often stained my clothing. Subsequently, I was placed on a surgical waiting list. By the time my surgery arrived, the situation had worsened significantly, making the procedure even more traumatic and painful than anticipated. The surgeon ended up removing more tissue than originally planned. During my recovery, I inspected the surgical site and discovered a noticeable indentation at the top with various irregular bumps extending down. The doctor assured me that these would eventually fade, but instead, they collected lint and hair over time. Fast forward a year, and I began to notice the same familiar odor again, filling me with anxiety about a potential recurrence. Now, as an 11th grader, I am under pressure to maintain good grades and cannot afford to miss school. Presently, my symptoms include the telltale smell, although I haven’t observed any discharge or developed any additional openings aside from the dimple left from my previous surgery. Before the operation, the infected sinuses extended close to the rectum, which is why I am concerned that a new pilonidal sinus may have formed in the same area. At this moment, I am free from pain but cannot shake the anxiety surrounding the reappearance of the odor associated with this uncomfortable condition.
