Exploring MRI vs. CT Scans for Headache Evaluation
Greetings! My husband, aged 33, has been suffering from persistent headaches for the past couple of months. These headaches predominantly affect the right side of his head, specifically behind his eye, and tend to surface several times each week, particularly in the evenings. Relief is often found with extra-strength Tylenol, although there have been instances where the pain has persisted throughout the night and into the following day. The discomfort intensifies when he bends over or makes any sudden movements. In an effort to manage his symptoms, his doctor recommended magnesium supplements, which initially seemed to reduce the frequency of the headaches for a few weeks; unfortunately, the relief was only temporary as the headaches returned. He underwent blood tests, revealing that all results were normal apart from a minor elevation in his white blood cell count, which the physician indicated could potentially relate to a bacterial infection. My husband experienced a mild cold during this time, yet the doctor reassured us that these two issues were unrelated. Although he takes a multivitamin designed for men, he has maintained that routine long before these headaches began. For additional context, he sustained a moderate traumatic brain injury in his early twenties, which resulted in a blackout and a loss of about two weeks of memory. Fortunately, he has been doing well since that incident. With the resurgence of his headaches, his doctor has recommended a CT scan. However, I’m curious if opting for an MRI might be a more suitable choice. He has undergone approximately five CT scans in total due to his previous TBI and a back injury. I recall my doctor expressing concern over frequent CT scans at a young age, which has led me to seek guidance. My main inquiry is: would an MRI provide sufficient imaging quality to help determine the underlying cause of his headaches?

It’s understandable to be concerned about your husband’s persistent headaches, especially given his medical history. Both CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) scans are valuable tools, but they serve different purposes and have different considerations.
Main Points:
- Persistent headaches require careful evaluation to identify potential causes.
- Both MRI and CT scans can help diagnose underlying issues, but they differ in imaging quality and risks associated with frequent use.
- Given his history of a traumatic brain injury and your concern about repeated CT scans, an MRI might be a prudent option.
Explanation:
Your husband's headaches, especially localized behind his eye and worsening with certain movements, may indicate various conditions, including migraines, tension-type headaches, or even issues related to his prior brain injury. While CT scans are often used in urgent settings to check for significant issues such as bleeding or fractures, MRI scans provide more detailed images of soft tissues and can help visualize the brain's structure more comprehensively.
Regarding your concern about exposure to radiation: CT scans involve X-rays and can add up over time, which is why you might be aware of the possible risks associated with multiple scans. MRI, on the other hand, does not use radiation, making it a safer option for those needing frequent imaging.
Next Steps:
-
Discuss the MRI Option: Talk to your husband’s doctor about the benefits of an MRI over a CT scan in this context, especially considering the details of his headaches and medical history.
-
Monitor Symptoms: Keep a log of his headaches, noting the frequency, intensity, duration, and any possible triggers or accompanying symptoms. This can provide valuable information for his healthcare provider.
-
Consider Additional Treatments: In addition to magnesium, explore other preventive treatment options for headaches such as lifestyle modifications (hydration, regular sleep, dietary tracking) or consultation on medications specifically for headache management.
-
Follow-Up: Ensure there is a plan for follow-up after the imaging to discuss results and adjust his treatment plan accordingly.
By approaching this proactively, you’ll help ensure that your husband receives the best care possible while minimizing unnecessary procedures. Let me know if you have further questions or need more specific information!

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.
Persisting Chills Without Fever for Three Weeks After a Cold
Greetings! I'm a 30-year-old male dealing with a rather unusual situation, and I'm at a loss for what to do next. As mentioned in the title, I recently experienced a cold, which presented all the expected symptoms, but the chills have lingered. It's been around three weeks now, and I still feel cold despite wearing multiple layers and having the heater running in my home. Strangely, throughout this episode, I haven't had a single fever. I consulted my primary care physician, who also seemed puzzled by my symptoms. She has requested some blood tests which are scheduled for Monday, even though I had blood work done three months ago that showed normal results. Does anyone have insights into what might be causing this? I understand there could be various explanations, but I'm unsure how to proceed. I am not currently on any medications and don't have any known chronic health conditions. Any guidance on how to tackle this issue would be greatly appreciated! 🙏
Questioning Cipro for C. diff Treatment
My mother, who is 53 years old, has developed C. difficile which seems to have occurred without any recent antibiotic use, suggesting a potential viral source for the infection. In the emergency room, she was prescribed Ciprofloxacin (Cipro) taken twice daily for a week, along with Metronidazole (Flagyl) at the same dosage and duration. However, I am puzzled by the inclusion of Cipro in her treatment regimen. Isn't there a possibility that this medication could aggravate the situation? I’ve come across information indicating that Cipro might potentially lead to C. diff infections rather than help treat them. Is this correct? Would it be advisable for her to consult her primary care physician to discuss alternative antibiotic options?
Am I at Risk of Rabies?
I’m starting to worry. An unvaccinated cat was on the couch with me, and I had a fresh cut on my thigh where his fur made contact. That was yesterday, but the cat hasn’t returned home today—it’s been roughly four days since I last saw him. Should I be concerned about potential rabies exposure? For context, I’m a 5’7” female, weighing around 150 pounds. I’m not on any prescribed medications, and I don’t smoke, drink, or use any recreational drugs.
Should I Consider Preventative Treatment for My Cats with Worms?
F19, I currently only have a Nexplanon for medication, and I often feel self-conscious about my height and my weight, feeling a bit stubby. This situation feels particularly unsettling for me since I have an existing fear of pests on animals. I'm questioning if my reaction is overly intense or if I'm not taking this seriously enough. Right now, I’m taking care of my mom’s house from Wednesday until early Monday. They have a spacious home and five cats that live partially indoors (since they are on a farm, some cats stay fully outdoors while others are indoor pets). Recently, I believe I spotted one of the cats vomiting a worm, likely intestinal worms. I would typically ask the vet forum for advice, but they don’t allow medical inquiries, so I’m wondering just how concerned I should be about this situation. I’m avoiding any contact with them, keeping things clean, but the thought of getting worms is really disturbing to me. Is this something to be genuinely concerned about? The house itself is tidy, and it doesn’t have that unpleasant, musty smell often associated with haywire cat environments. They also own two dogs, one of which enjoys licking my legs, which I find pretty gross. I lack regular access to medical services due to my current unemployment and not being in school. If I had that option, I would simply schedule a checkup. However, if this is a matter of real concern, I am open to seeking medical assistance. If there are any over-the-counter preventative treatments available at stores like Walmart, I would appreciate any suggestions. I find it difficult to discuss this with my mom because she often dismisses my concerns about pests and bugs, so I can’t rely on her for help. Please advise me on the best course of action! 😭
