Concerns About Radiation Exposure
Hello everyone, I’m hoping to get some insights, particularly from those in the radiology or oncology fields: I’m a 39-year-old male who, during my 20s, dealt with significant anxiety that stemmed from various traumatic experiences, including a turbulent relationship and witnessing the decline of my partner’s father. This led to a fear of illness and a desire to not leave my children behind. Over that period, I found myself frequently visiting hospitals due to persistent headaches and chest pains, which later turned out to be undiagnosed migraines along with discomfort from upper respiratory issues and exercise-related strain. Prior to this, I had several sports-related injuries that necessitated CT scans, particularly after sustaining concussions. Fast forward to now, at 39 years old, I have undergone around 25 CT scans of my head, including several more recent ones. Just lately, I had two scans that played a crucial role in diagnosing Guillain-Barré syndrome, after other conditions were ruled out. Thankfully, I successfully overcame my hypochondria years ago through therapy. Currently, however, I am experiencing a headache accompanied by weakness in my legs and a soreness that feels akin to after running a marathon, along with a heightened pressure sensation in my ears. I suspect it could be viral in nature. The headache initially surfaced following ejaculation; it subsided but has returned. A nurse informed me that a CT scan might be necessary as there are concerns about a possible brain bleed based on my symptoms. The physician is set to make a decision later tonight. While I have my doubts about the severity of my condition, I acknowledge that I’m not a medical professional. I have some questions regarding my risk concerning potential cancer due to my history with CT scans: 1) What is my current risk level for developing brain cancer based on my previous CT scan history? 2) Would undergoing another CT scan significantly increase this risk, or is it justified given my current symptoms? Ultimately, my priority is to be present for my children; their mother is quite difficult, and they truly need a stable, caring parent in their lives. But if it turns out that I may indeed have a bleed, I understand that the need for imaging surpasses the concern of radiation exposure. Thanks for your help and insights. If I allow them, the scan is scheduled for tomorrow morning. I truly value your support and all the work you do.

Thank you for sharing your situation and concerns. It’s understandable to be worried about your health given your extensive history with CT scans and recent symptoms. Let’s address your questions about radiation exposure and your current health status.
Main Points:
- Risk from Previous CT Scans: Your risk of developing cancer from prior CT scans is very low, especially when balanced against the immediate need for accurate diagnosis.
- Justification for New CT Scan: Given your current symptoms, particularly the headache, weakness, and possible pressure in the ears, a CT scan may be necessary to rule out serious conditions, like a brain bleed.
Explanation:
-
Risk of Developing Brain Cancer: While CT scans do involve radiation, the risk of cancer from the dose received from 25 scans is cumulative but generally remains quite low for most individuals. According to the American College of Radiology, the lifetime risk of a fatal radiation-induced cancer from one CT scan of the head in a younger adult is about 1 in 10,000.
-
Need for Further Imaging: The urgency of identifying a potential brain bleed or other serious condition typically outweighs the risks of radiation exposure. Your current symptoms—particularly the headache and leg weakness—could indicate a serious issue that warrants immediate investigation. The medical team has access to guidelines that help them determine when the imaging is necessary, and they are prioritizing your safety.
Next Steps:
-
Follow Through with the CT Scan: If your physician recommends the CT scan, it’s important to proceed. It provides critical information that can guide your treatment and help ensure your safety.
-
Monitor Symptoms: Note any changes in your symptoms, especially regarding headache severity, leg weakness, or new symptoms. This information can be crucial for your healthcare team.
-
Stay Hydrated and Rest: Ensure you maintain good hydration and rest as your body may be under stress from the current symptoms.
-
Reassure Yourself: Remember that you're taking proactive steps to ensure your health and the well-being of your children. Addressing a potential problem now can prevent larger issues later.
-
Seek Support: If feelings of anxiety arise, consider engaging with a mental health professional to help navigate these moments and reinforce your coping strategies.
Please remember, your health is the priority, and the scan will help provide clarity on your current situation. You’re taking the right steps by seeking answers and understanding the implications of your health history. Let me know if you have any further questions or need more clarity on any aspect.

Understanding EEG Results for My 22-Month-Old Son: Insights Needed
Could someone help clarify this for me? My son, who is just 22 months old, hasn’t started walking yet, becomes tired easily, and has been experiencing behavioral outbursts. He had a febrile seizure in February 2025, followed by another unexplained seizure in April 2025, which led us to consult a neurologist. Since he was 3 months old, he has been receiving therapy from a physical therapist for torticollis. At birth, he spent five days in the NICU due to issues with meconium aspiration. A recent MRI showed normal results, and he also had a follow-up EEG after one conducted in July 2025. The results from this recent EEG were abnormal for a pediatric patient in awake, drowsy, and sleeping states. Notably, there were brief episodes of left frontotemporal delta slowing, which occurred mainly when he was awake and drowsy. There were no signs of epileptiform activity detected. In contrast, the EEG performed back on July 3, 2025, was deemed normal for both awake and drowsy states, again with no evidence of epileptiform irregularities, although it did not capture any sleep data. This examination was prompted by the child's existing history of febrile seizures. Importantly, he is not currently on any anti-seizure medications. The EEG procedure used standard electrode placements per the 10-20 system, conducted a single-lead EKG, and included continuous video monitoring. During the analysis, the background activity was symmetric, indicating some anterior-posterior (AP) organization, with a dominant rhythm of 50-80 microvolts at 7 Hz. His drowsy state was marked by a reduced amount of eye blink activity, less breathing motion interference, and a generalized slowing in theta/delta frequencies. Stage II sleep exhibited spindles and vertex waves patterns. Additionally, there were intermittent bursts of 250-300 microvolts in the left frontotemporal region with semi-rhythmic activity of 2-4 Hz, mostly observed during wakefulness and drowsiness. No definitive epileptiform discharge was noted. Photic stimulation during the test did not elicit a strong response, and hyperventilation was not conducted during this session.
INTENSE Spine Discomfort, Breathing Difficulties, Muscle Twitches, and Sweating
To elaborate on the situation mentioned in the title, I’ve been experiencing unusual muscle twitches and spasms for the past few days, along with some discomfort in my back. However, today, I felt an unexpected sharp pain shoot through my spine, which has left my legs feeling numb and made it impossible for me to sit up straight. Additionally, I’ve been dealing with cold sweats for the last hour and struggling to breathe properly. Perhaps I’m just overanalyzing things and it’s a common occurrence, but the intensity of the pain is overwhelming—it's truly unbearable. I’m shaking quite a bit, and unfortunately, my parents aren’t responding to my attempts to reach them for help. I have a history of a chronic heart condition and arthritis, yet I’ve never experienced pain this severe, especially in my spine. For context, I am nearly 15 years old and female. My current medications include pain relievers, anxiety medication, beta blockers, and some vitamins, though those specifics may not be particularly relevant. I don’t smoke; however, I have tried vaping a few times, which might not matter much, but I thought it was worth mentioning as it was requested.
Understanding Atrial Fibrillation and Thyroid Issues: Variability in Cardioversion Decisions
Hello everyone, I’m reaching out for guidance regarding my mother’s current health situation, and I’d greatly appreciate any shared experiences or thoughts. **My mother's background:** - **Age**: 55 years - **Weight**: Recently dropped to 116 kg from 118 kg in just two days, likely due to diuretics. - **Health history**: Previously an underactive thyroid, undiagnosed and untreated, now presenting as overactive. - **Medications**: Currently taking thyroid medication and a beta-blocker (Rapiblock). **Current health status:** My mother has been hospitalized since Tuesday, experiencing **atrial fibrillation with heart rates exceeding 200** beats per minute due to her thyroid's hyperactivity. - The plan for cardioversion was initially settled on Tuesday. However, the following day, the medical team advised postponing it until her thyroid levels could be stabilized, believing that her heart rate would return to normal once her thyroid condition was managed. - Her **obesity** precludes her from undergoing a transthoracic echocardiogram, and due to her thyroid concerns, she cannot handle contrast dye (this has been a consistent issue for over four years). Therefore, the only feasible option was a **transesophageal echocardiogram (TEE)**, which has yet to be performed. - She has been prescribed various medications including beta-blockers and thyroid treatments in the past. - On Friday, a doctor proposed proceeding with cardioversion; however, the attending senior physician objected. - Today (Saturday), another clinician has expressed a desire to move forward with cardioversion, having initiated a new medication, as the senior physician is unavailable. - **Communication has been unclear**, as we were notified of developments by a nurse rather than the physician in charge, causing confusion and anxiety. - Currently, only a **chest X-ray** is scheduled, and the TEE remains unaddressed. **My inquiries are as follows:** 1. Is it common for medical professionals to have varying opinions and frequently revise medication or treatment plans like cardioversion? 2. Is it safe to conduct cardioversion in the absence of a TEE? I presumed that this was a standard procedure to exclude the presence of blood clots. 3. Is it usual practice to have only a chest X-ray prior to moving ahead with cardioversion? 4. How typical is it for patients or their families to not be directly informed about treatment changes and learn about them through nursing staff instead? I recognize that this cannot substitute for professional medical advice. I’m simply trying to discern whether these circumstances are typical or if we should express our concerns more assertively with the healthcare facility. Thank you for your insights!
28-Year-Old Male Experiencing Scalp Sensations Post-Amitriptyline Treatment
I am a 28-year-old man in generally good health, without any cardiac concerns. Approximately a month ago, I encountered intense pain localized to one side of my head, which was unresponsive to paracetamol. However, a single dose of a migraine treatment provided substantial relief. Following that, I began a regimen of amitriptyline, starting at a nightly dose of 10 to 25 mg. While my head pain has diminished significantly—by about 90 to 95%—I now experience occasional uncomfortable sensations on my scalp. These feelings include pins and needles, a cooling sensation, and some crawling feelings near my hairline and ears. There are fleeting moments where I feel brief throbs lasting a second, but I do not have any persistent headaches. To clarify, I do not experience any of the following: - Nausea - Weakness in my limbs - Numbness - Changes in my vision - Coordination difficulties - Seizures The symptoms I have are transient, shifting around and often intensifying when I become conscious of them or as the day progresses. I would like to know: Is it common to experience these sensations during the recovery stage following episodes of neuralgia or migraine-like discomfort? Additionally, could the amitriptyline potentially be causing these temporary paresthetic sensations? I am seeking some reassurance or advice on what is typically observed during this healing process. Thank you.
