Clarification on Brain MRI Findings
Hello, I recently underwent a brain MRI and I am seeking some clarity regarding the results. I am a 26-year-old woman, and I've been diagnosed with Hashimoto's disease since 2018. In 2021, I began experiencing migraines, vertigo, along with a persistent stiffness in my neck and shoulders. Additionally, I have noticed a lump at the base of my skull during this time. After ruling out any cardiac issues through various tests and confirming that my blood work is normal, I opted for the MRI to exclude the presence of tumors. Fortunately, no tumors were detected, but the scan did reveal a few cysts. Here’s where I’m confused: the report mentions a Thornwaldt cyst; however, from what little information I've found—since this condition is quite uncommon—it appears to be located in the nasal cavity. Yet, my MRI suggests that it is related to the bump at the back of my head. Is this discrepancy possible? Could there be an error in the interpretation of my results? The lump I’m concerned about is situated on the left side at the base of my skull, quite close to where the occipital nerves would typically be situated. Is it feasible for the cyst to have moved to this area, or might the MRI diagnosis be inaccurate? I appreciate any assistance in helping me understand this situation better.

It’s understandable to feel concerned about the findings of your brain MRI, especially given your symptoms and medical history. I’ll clarify the information regarding the Thornwaldt cyst and its implications for your situation.
Key Points
- Thornwaldt Cyst Location: Thornwaldt cysts are usually located in the nasopharynx (the area behind the nose) and are often asymptomatic. They can sometimes be detected incidentally on imaging.
- Lump at the Base of the Skull: The lump you’re feeling at the base of your skull may not be directly related to the Thornwaldt cyst. It’s possible that the MRI findings mentioned could describe two separate issues.
Explanation
- Cyst Details: Thornwaldt cysts can appear on MRI, but they generally wouldn't cause a lump on the neck or base of the skull. The lump you described could arise from several causes, including muscular tension, benign bone growths, or even lymph nodes reacting to inflammation.
- Interpreting the MRI: It’s essential to remember that imaging can be complex, and subtle variations may need clarification. While it’s uncommon for a Thornwaldt cyst to cause noticeable symptoms, it is unlikely for it to present as a lump in that area.
Next Steps
- Document Symptoms: Keep a detailed record of your symptoms (such as pain, stiffness, or changes in the lump) to share with your healthcare provider.
- Follow-up Appointment: Request a follow-up consultation with your doctor or neurologist to discuss the MRI results in detail. Ask for clarification specifically about the Thornwaldt cyst and the lump.
- Consider Imaging Review: If you still have concerns about the accuracy of the MRI interpretation, discuss the possibility of having the scans reviewed by another radiologist for a second opinion.
- Evaluate Symptoms: Monitor the lump for any changes in size, shape, or associated pain. If you notice any rapid changes, that would warrant more urgent evaluation.
Your symptoms and concerns are valid, and seeking clarity is a critical step toward understanding your health. Please don’t hesitate to reach out for more information as you navigate this process.

Dealing with Esophageal Cramping and Heartburn while on Oral Minoxidil
Hello everyone. I’m a 37-year-old male who frequently experiences alopecia areata, particularly during stressful periods at work. Recently, my dermatologist recommended oral minoxidil in 2.5mg capsules to speed up my hair restoration process. Since I began this treatment, I’ve encountered several side effects, including elevated heart rate, dizziness, shortness of breath, heartburn, and esophageal cramps, albeit not all at once. Most of these issues have subsided, but the cramps and intermittent heartburn persist. I find the cramps tend to occur after meals, accompanied by a sensation as if I can feel the food moving through my esophagus; this uncomfortable feeling can linger for hours before fading, only to return with my next meal. The discomfort isn’t severe enough to incapacitate me, but it can be quite bothersome, with some days being better than others. Should I consider halting the medication, or should I wait until my next scheduled appointment to discuss this? I live in a rural area, making it difficult to find sooner availability, as the next appointment isn’t for another month. I appreciate any advice you might have!
Ongoing Symptoms Post-Concussion: Seeking Insights
Hello everyone, I’m a 25-year-old male and experienced a significant car accident about two and a half years ago. Although I didn't black out during the incident, I felt disoriented and unsettled immediately afterward. Since that day, my health has noticeably deteriorated, and I'm attempting to discern whether my current struggles are commonplace or if something more serious might be overlooked. Here’s what I've been grappling with: I endure daily headaches that typically originate in the back of my head or neck, gradually migrating towards my temples or eyes. Conditions that intensify these headaches include bright screens, excessive light, noise, and bustling surroundings. When I attempt to power through the discomfort, I sometimes see halos around lights or experience visual static. Mentally, I find myself exhausted very quickly. Concentrating becomes a challenge, and I frequently lose track of my thoughts or encounter difficulty finding the right words. Engaging in conversations or attending meetings can drain me significantly. Additionally, I become easily overwhelmed, especially in loud or crowded situations. Tinnitus is another issue I face, as the ringing in my ears is a constant presence. Since the incident, I’ve noticed weakness in my left hand; my ring and pinky fingers often curl up like claws. An electromyography (EMG) test revealed damage to the ulnar nerve, which accounts for some of this phenomenon. Unfortunately, it hasn't improved, impacting my ability to type, grip objects, and carry out everyday tasks. I also experience occasional facial twitching, jaw tightness, and short bouts where different parts of my body feel weak or tremble, but these symptoms are temporary. Fatigue is a significant battle for me. I struggle with poor sleep quality, waking up feeling unrested, and sometimes experiencing anxiety first thing in the morning. Even on days when the pain level is tolerable, my energy depletion restricts my activities. Here’s a summary of what medical evaluations have revealed: • My brain scans returned normal results, revealing only minor, nonspecific findings like white matter changes in certain regions. • The blood vessels in my brain appeared healthy. • EEG results indicated some slowing but no evidence of seizures. • More invasive tests ruled out any major health concerns. • Mild sleep apnea was detected. • Cognitive assessments showed deficits in attention, processing speed, and memory. • Eye examinations indicated challenges with tracking and focusing post-injury. What has proven somewhat beneficial includes: • Migraine medication has helped lessen the severity of my headaches. • Telecommuting allows me to take frequent breaks. • Engaging in occupational, speech, and vision therapy whenever possible has been somewhat advantageous. I maintain a full-time job, but managing it drains a considerable amount of my energy, leaving little for family interactions, social engagements, or time for recovery. I’m at a stage where I’m seeking clarification on several points: 1. Is it common for post-concussion symptoms to persist for such an extended period despite normal scan results? 2. When is it appropriate to seek an alternative explanation rather than accepting a diagnosis of merely post-concussion syndrome, stress, or anxiety? 3. Is it typical for fatigue to be the most pronounced and debilitating symptom? 4. Are there often overlooked aspects, such as sleep quality, visual processing, nerve health, or nervous system function, that should be reevaluated? I’m not seeking a diagnosis—just some insight. I want to determine whether I’m on a reasonable track or if I should be considering different inquiries. Thank you to all who have taken the time to read my message.
Understanding Post-Surgical Pain After Ganglion Cyst Removal
I’m 17 years old (female, though I prefer He/him pronouns) and I have Ehlers-Danlos Syndrome (EDS) along with Dysautonomia. Currently, I’m not taking any medications that might impact my situation apart from an SNRI and birth control to manage cramping. Around a month ago, I underwent surgery to remove a ganglion cyst located on my dominant wrist (the right one). This cyst had been present for roughly three years, and despite my doctor attempting to aspirate it, the procedure was unsuccessful due to its firmness, leading to surgical intervention. This cyst significantly limited my wrist mobility. Now, after approximately four weeks post-surgery, I can say that my wrist is mostly improved. The scar is healing fairly well, and I’ve regained about half of my wrist’s mobility compared to the left one. Yet, I still experience significant pain when I move or apply pressure on the area that housed the cyst. Is this pain considered normal? Additionally, my fingers are in constant discomfort, and my wrist seems to dislocate frequently. Due to my EDS, I am accustomed to joint pain and dislocations, but this particular pain feels more severe than what I usually endure. When I brought this up with my surgeon, he dismissed my concerns, stating that such dislocations are common for individuals my age. However, I experience dislocations at least twice daily, and the process of resetting them creates such a loud sound that I've been asked to leave classes to avoid disturbing others. Is this normal? Could it be related to the cyst? Moreover, about four days ago, I noticed a small lump forming on my wrist just above the surgical area. When I consulted my doctor about it, he informed me that it was a benign fatty tumor and assured me it wasn't a serious issue. However, I've never encountered anything like this before, and while the lump is not painful, soft, and relatively small, I’m puzzled about its sudden appearance. Why did this occur, and what could explain my doctor’s nonchalant attitude towards my symptoms? I understand that experiencing pain and limited mobility after surgery is not unusual, but given my doctor’s dismissive approach towards my concerns, I felt compelled to seek insight here as well. He often seems skeptical about the symptoms I report, making it difficult for me to fully trust his evaluations.
Concerns About Changes in Partner's Semen Consistency
At 19 years old, I’m seeking some insights regarding a situation. My girlfriend, who is also 19, has experienced a noteworthy change in her semen consistency during our intimate encounters over the last two to three weeks. To provide some background, she stands at 5 feet 5.5 inches tall and weighs approximately 130 pounds. Her ethnicity is Caucasian, and she is from Canada. Historically, my girlfriend has been in good health without any significant medical conditions. Currently, she is not taking any medications. Previously, she had a history of frequent vaping, but that was about a year ago, and now she limits it to occasional use. The change in her semen is quite striking; it appears very thick, white, and somewhat chunky, rather than being mostly liquid. There are some liquid components, but the thick texture predominates. Throughout this period, she has maintained her regular diet, and importantly, there are no signs of a urinary tract infection or sexually transmitted disease. Neither does she experience any pain or unusual odors. This alteration has raised some concerns for her, and while I am trying to be supportive, I am uncertain about the potential causes. We searched online for explanations, but the reactions we found mostly related to digital sources that discussed various infections or medical conditions, none of which seemed to match her symptoms. Does anyone have insights or similar experiences regarding this matter? It would be appreciated in easing her worries and determining the best course of action.
