Seeking Clarity on Imaging Options: MRV vs. CT Scan
I'm a 23-year-old woman, measuring 5'2" and weighing 140 pounds. My only occasional health supplements consist of melatonin and a multivitamin. Currently, I'm grappling with a dilemma regarding an imaging test. My doctor insists on scheduling a CT scan, but I would prefer an MRV and I’m looking for some independent advice on what the best course of action is. At the start of 2025, I visited an OB/GYN due to my New Year’s resolution to address persistent discomfort I experienced with tampons and during intercourse. After conducting some internal examinations, they didn't find any obvious issues and referred me to pelvic physical therapy. The first pelvic therapist diagnosed me with vaginismus and suggested I engage in breathing exercises to help alleviate tension in the pelvic floor. I expressed skepticism, feeling that my situation was more complex than simply a meditation issue. Eventually, I performed the recommended exercises, but instead, I began to feel a significant discomfort in my lower back that was alleviated while sitting on a toilet or a cushion. This change occurred gradually over a span of roughly five weeks. When I reported this new pain to my therapist, her response was concerning; she decided to connect me with another specialist who could better address nerve-related issues. Upon meeting with the new therapist, she conducted several physical assessments, discovering that my symptoms were connected to nerve dysfunction. She explained that I couldn't effectively engage my pelvic muscles due to nerve irritation. We attempted some gentle nerve gliding exercises, but after just one session, I was in excruciating pain for a month, to the extent that even brief sitting became impossible. A couple of months later, I sought help at a pelvic rehabilitation center where they determined that steroid injections were necessary due to severe nerve irritation. I was prescribed five injection sessions over five weeks. However, after about three sessions, I began encountering strange nerve jolts and uncomfortable sensations in my legs. It was at this point that I learned I might be dealing with pelvic congestion syndrome (PCS). Throughout this process, every healthcare provider I consulted was aware that I had experienced a troubling history, having dealt with more than ten hemorrhoids and ongoing issues with bladder control and pain during sexual activities. Alarmingly, none of these professionals seemed concerned about my hemorrhoid history or suggested any imaging or treatment adjustments to address my ongoing symptoms. I later discovered that the steroid injections were supposed to be spaced out every couple of months rather than weekly and that they may have administered more than the recommended dosage. While contemplating my treatment options, I wanted to undergo a 3T MRN and MRV to investigate potential nerve scarring, fluid complications, May-Thurner syndrome, and any evidence of nerve entrapment exacerbated by the therapy or injections. However, I was initially scheduled only for a pelvic CT scan. When I inquired about the need to examine for May-Thurner syndrome, they reluctantly considered adding another test. To my surprise, they claimed they were unable to find the MRN imaging option on their list, yet assured me they would look into it. My concern was that exposing my ovaries to radiation with a CT scan seemed excessively harsh. After my research, I concluded that an MRV might provide clearer insights for diagnosing PCS, particularly in relation to my existing nerve issues, as it could reveal how the veins are compressing against my nerves, leading to my persistent lower body pain. Despite presenting this to my healthcare team, they remained adamant that an MRV would likely yield inconclusive results. I couldn't help but wonder whether their preference for a CT scan stemmed from convenience rather than medical necessity. It often feels as though healthcare professionals prioritize their own ease over patient welfare; perhaps they lean toward treatments that allow for faster administration or easier reimbursement from insurance, rather than genuinely exploring the most beneficial options for the patient. For context, I had underwent a Pelvic Venous Duplex ultrasound with Doppler, which indicated abnormal vein diameters; one side measured around 5 mm when it should have been around 3 or 4 mm, while the other measured approximately 7.5 mm. This finding prompted further urgency for a CT scan to assess PCS, but I remain apprehensive about the radiation and question whether a CT would adequately address the complexity surrounding my condition, given the involvement of hypertonia and nerve issues. I realize this might come off as a naive inquiry, but trust me, after being let down and suffering due to the oversight of multiple doctors, I now scrutinize every advice I receive from medical professionals, even when it seems sound on the surface. I regret not researching the standard care procedures prior to agreeing to those steroid injections, and I currently endure considerable discomfort while sitting, standing, or even walking. I sometimes feel a deep sense of regret about placing my trust in the medical community.

It's completely understandable to feel overwhelmed and uncertain after navigating a complex medical situation, especially with ongoing discomfort and past experiences that have led to frustration. The choice between a CT scan and an MRV can significantly affect your diagnosis and treatment, so it's essential to weigh the benefits and risks clearly.
Key Points:
-
Imaging Purpose: A CT scan is commonly used for assessing structural issues in the pelvis but does expose you to radiation, which raises concerns, especially for individuals of childbearing age. An MRV (Magnetic Resonance Venography) provides detailed images of blood vessels without radiation, which may be beneficial for evaluating conditions like Pelvic Congestion Syndrome (PCS).
-
Health Context: Given your history of pelvic pain, nerve issues, and abnormal vein diameters, a more targeted imaging approach, such as the MRV, might help highlight vascular conditions affecting your nerves.
Explanation:
-
CT Scan vs. MRV:
- CT Scan: Fast and useful for identifying bony abnormalities, tumors, or major vascular issues, but does involve radiation, which can be a concern for reproductive health.
- MRV: Helps visualize veins and blood flow without radiation. Particularly relevant for diagnosing PCS since it can show vein compression affecting the pelvic nerves.
-
Your Concerns: Given your apprehension about the health impacts of radiation, combined with the need for clarity about your nerve and vein issues, it seems reasonable to advocate for an MRV.
Next Steps:
-
Communicate with Your Healthcare Team: Share your research and concerns regarding the CT scan with your doctor. Emphasize the potential benefits of an MRV, such as its safety profile and relevance to your symptoms.
- Prepare a list of questions or points you want to convey, including your fear about radiation exposure and your desire for a comprehensive understanding of vein interactions with your nerves.
-
Consider Getting a Second Opinion: If your provider remains insistent on the CT scan and dismisses the MRV, seeking a second opinion from a specialist in pelvic pain or vascular disorders might provide a fresh perspective and alternative options.
-
Track Symptoms: Keep a detailed log of your discomfort, noting when it occurs and any factors that seem to exacerbate or alleviate it. This information can help guide further evaluation and may support your case when discussing imaging options with healthcare providers.
-
Stay Informed and Empowered: Continue researching your conditions. Understanding the implications of your symptoms and the typical imaging methods can provide you with more confidence when discussing your options with health care professionals.
I encourage you to prioritize your health and ensure you feel comfortable and informed about the investigations you undertake. It's commendable that you're seeking to advocate for yourself in your health journey. Please feel free to reach out if you need further information or support.

Experiencing Severe Health Issues at 25
At just 25 years old, I'm facing some serious health challenges. It truly feels like my body is being overwhelmed. I've been dealing with rapid heartbeat, episodes of dizziness, a feeling of tightness in my chest, and a profound sense of fatigue. My ability to engage in daily activities has been significantly hindered. I consulted with a hematologist who has arranged for me to receive iron infusions; however, the earliest appointment is a month away. According to the doctor, my iron levels are critically low, but I'm starting to question if waiting a month is too long. Should I be concerned that these symptoms may indicate something more serious than mere discomfort? I’ve shared my lab results in the comments for reference.
Skin Irritation Following Cat Scratches
I am a 40-year-old male living with Type 2 diabetes. Recently, my rather overweight cat has been scratching me when he jumps into my lap (I assure you, these are purely feline-related injuries and not self-inflicted). Typically, I sit with my leg elevated on my knee, which gives him a good spot to leverage himself up. The marks are reddish but not swollen, and there are no signs of infection like foul odors or discharge. The areas are just slightly warm if touched. I have been keeping the scratches clean by using antibacterial soap and allowing them to air dry before applying a thin layer of Neosporin. I'm considering visiting urgent care for a professional opinion on whether they require further examination. The photo was taken just after I showered, showcasing the condition.
Assessing the ER Treatment for a Child with Mastoiditis
Recently, I had to take my son to the emergency room due to his discomfort from left ear pain, accompanied by a fever of 101°F, notable yellow discharge, and pronounced swelling and redness around the mastoid bone situated behind his ear. A pediatrician friend of mine, who practices out of state, advised me to visit the ER for a scan of the mastoid area for a thorough assessment. Upon arrival at the ER, after about an hour of monitoring, his vital signs and overall condition appeared to stabilize; his fever had subsided, and the redness on his mastoid had diminished slightly, with only a minor forward tilt of his ear remaining evident. The medical team conducted various tests, including blood work—showing a SED rate of 54, a CRP of 21.3, and a WBC count of 15.85—as well as a CT scan with contrast. This imaging revealed moderate to severe opacification of the mastoid cavity but thankfully indicated no skeletal damage. An ENT consultation was arranged, during which I interacted with the ENT team, albeit not directly with the physician. Eventually, my son was diagnosed with acute mastoiditis and otitis externa. The treatment approach recommended involved standard oral medication, specifically Augmentin, dosed at 40 mg per kg (totaling 800 mg daily), along with Cipro/Dex ear drops. They administered an initial dose of the oral Augmentin before we were discharged from the ER that evening. My pediatrician friend expressed surprise at the conservative nature of this treatment strategy, which was echoed by three others—Dr. Grok, Dr. Gemini, and Dr. ChatGPT. Fortunately, my son appears to be recovering well. During today’s follow-up visit with his pediatrician, she remarked that he should have received a dose of Rocephin in the emergency room. She then proceeded to administer it to him in her office and increased his Augmentin dosage to Augmentin ES. This leads me to question whether the treatment my son received in the ER was appropriate based on standard medical guidelines for mastoiditis, or did it fall short of what is typically expected for such a condition?
Desperately Seeking Answers After Six Years
I kindly implore anyone who can shed light on my situation or provide assistance. For the past six years, my journey for a correct diagnosis has left me with nothing but a series of misdiagnoses. This ordeal took root after an extended stay in the United States, followed by my return to Sydney, Australia, where I found myself confined in a room plagued by black mould during the lockdown. While in the U.S., I endured episodes of food poisoning, lived with mould, and had to contend with a smoking environment, despite my repeated pleas for it to stop due to my struggles with breathing. Moreover, the food quality there contributed to my gastrointestinal issues. Upon my return, I began facing respiratory troubles and developed multiple food intolerances, resulting in unusual reactions to certain foods. I experienced symptoms such as shortness of breath, shakiness, heart palpitations, hot flashes, and persistent nausea. Eventually, I discovered that black mould had exacerbated some of my issues, but I continued to struggle with foods that I had previously consumed without trouble. Through extensive self-exploration and experimentation, I concluded that sulphur-rich foods, particularly garlic and onions, along with acidic, oily, and carbonated items, were primarily responsible for my symptoms. An upper endoscopy was performed, which the doctors deemed normal, although there is a disagreement on whether biopsies were conducted. I had specifically requested one, but my gastroenterologist claims he cannot access the results. The procedure left me feeling extremely ill and weak for a week, making me hesitant to undergo it again. During my hospitalization post-endoscopy, I was briefly evaluated by an endocrinologist, but the encounter was unprofessional as he made advances towards my mother and left abruptly after her rejection. He subsequently misdiagnosed me with anorexia nervosa, declaring my mother as an enabler. It took me a year and a stool test ordered by my hormone specialist to refute that diagnosis, which severely damaged my trust in healthcare. Standing at 164 cm and weighing 47 kg, at age 26 and as a non-drinker and non-smoker, I often find myself scrutinized by doctors regarding my food intake. However, after showing them my food diaries, they generally fall silent, as I consume more than most healthcare professionals I've encountered, including substantial meals. The best responses I receive are suggestions to address my anxiety, perhaps consider returning to contraceptives (which I had hoped might help with weight gain but did not), or dismissing my symptoms based on the results of the endoscopy. Even though they claim no reflux was observed during the procedure, I hold strong reservations about whether they performed it correctly, given their inclination to prescribe SSRIs under the pretense of my anxiety and presumed anorexia, while I have no documented results verifying anything from the endoscopy. Additionally, they asserted I was not gluten intolerant, despite having been diagnosed with it at 12 years old. My dietary restrictions are a direct consequence of my health issues, and I assure you this isn’t just about anxiety. I am coping with Complex PTSD and Panic Disorder, but I am well aware of the distinct nature of my physical symptoms. Recently, I was diagnosed with Dysautonomia and possibly hypermobile Ehlers-Danlos Syndrome (hEDS), which are known to be associated with gastrointestinal conditions, though the specifics remain unclear. Furthermore, I experienced silent reflux during infancy, which was misdiagnosed until it caused severe damage to my oesophagus and led to extensive bleeding. As for my symptoms: *I suffer from chest spasms and the sensation of trapped gas. About two hours after ingesting garlic, I experience shivering, nausea, gas discomfort, tremors, heart palpitations, weakness, and shortness of breath, although I have yet to faint.* I had an appointment scheduled with an allergy specialist, but when I inquired about being tested for potential allergies to garlic and coconut, I was met with refusal, being told that those allergies won’t be tested since both are ubiquitous in foods, thus implying they are unavoidable. This response left me feeling bewildered, leading me to question if the issue lays with me. I earnestly seek assistance in understanding what is transpiring with my body and how I may compel medical professionals to take my concerns seriously, rather than dismissing them with the usual narratives that many women encounter: "it's anxiety, it's your weight, or it's your hormones." My hope is fading.
Eye Redness and Mild Discomfort
A 24-year-old male, who does not engage in drinking or smoking, has experienced discomfort in his left eye. Recently, he had been coping with a sore throat and had been using paracetamol and throat lozenges for relief, along with melatonin to aid sleep. Approximately a day ago, he became aware of a dull ache in his left eye while working at his computer. Upon inspecting his eye in the mirror, he observed redness localized in the lower part of the left eye. After 24 hours, the individual notes that the redness appears to be largely unchanged and the pain persists at the same level. He seeks advice on whether this condition warrants concern and if it is likely to resolve on its own.
